Energy Policy Minus Climate Policy Equals Disaster

I’m telling you nothing new when I say that in confronting Climaticide we face both an opportunity and a grave danger. On the one hand, if we change our behavior, we can not only save ourselves from the worst climate catastrophe but also, as a necessary part of the process, make our civilization more sustainable and more just. On the other, if we reject fundamental change and postpone meaningful action we will only travel further down the mistaken path that we embarked on when we decided to tie our fate to the exploitation of fossil fuels. With each missed opportunity and tipping point passed our future becomes more problematic.

That the world still finds itself heading down the road to ruin is in very large measure because America has betrayed its ideals and failed in its responsibilities. The destructive consequences of the Bush administration’s refusal to participate in international efforts to combat Climaticide in favor of a jingoistic, nationalistic, energy policy became even more starkly evident this week with news stories about the headlong race to exploit Canadian tar sands and problems with the Australians efforts to establish meaningful cap and trade emissions standards.

Let’s start with Alberta’s tar or oil sands:

Shell, Exxon-Mobil, Chevron, Canada’s Imperial and other companies plan to strip an area here the size of New York state that could yield as much as 175 billion barrels of oil. Daily production of 1.2 million barrels from the oil sands is expected to nearly triple to 3.5 million barrels in 2020. Overall, Alberta has more oil than Venezuela, Russia or Iran. Only Saudi Arabia has more.[my emphasize–JR]

This is what oil sands exploitation looks like.

Oil-sands operations, including extraction and processing, are responsible for 4 percent of Canada’s greenhouse-gas emissions, and that’s expected to triple to 12 percent by 2020. Oil-sand mining is Canada’s fastest-growing source of greenhouse gases and is one reason it reneged on its Kyoto Protocol commitments. Experts say producing a barrel of oil from sands results in emissions three times greater than those from producing a conventional barrel of oil.

(85.5kg CO2 per barrel compared to 28.6kg CO2). This is on top of the CO2 emissions from the actual consumption of the barrel of oil, which are around 430kg per barrel.

According to the world’s foremost climate scientist, Dr. James Hansen:

Reserves are hotly debated and may be exaggerated, but we know that enough oil and gas remain to take global warming close to, if not into, the realm of dangerous climate effects. Coal and unconventional fossil fuels such as tar shale contain enough carbon to produce a vastly different planet, a more dangerous and desolate planet, from the one on which civilization developed, a planet without Arctic sea ice, with crumbling ice sheets that ensure sea level catastrophes for our children and grandchildren, with shifting climate zones that cause great hardship for the world’s poor and drive countless species to extinction, and with intensified hydrologic extremes that cause increased drought and wildfires but also stronger rain, floods, and storms.[emphasis added–JR]

According to other experts:

David Suzuki, Canada’s most prominent environmentalist, and other critics warn that the environmental ramifications are too dire to ramp up oil-sands production.

Their [the oil companies investing in tar sands] projected rates of expansion are so fast that we don’t have a hope in hell of reducing greenhouse-gas emissions,” said Dr. David Schindler, an environmental scientist at the University of Alberta.

Other critics raise other environmental concerns:

Many critics are worried about the amount of water taken from Alberta’s Athabasca River. The extraction process uses 2 to 4 ½ barrels of water for each barrel of oil produced, according to the Pembina Institute, a nonprofit think tank.

There are concerns, too, about the tailing ponds next to the river. The ponds contain waste made from the separation of oil from sand. The toxic ponds take up 50 square miles of northern Alberta.

Jeff Short, a U.S. government scientist who studied the long-term effects of the Exxon Valdez oil spill, said if one of the ponds spilled into the river, the impact would be felt for decades — or centuries.

“It would be the equivalent of several hundred Exxon Valdez oil spills,” he said.

Note: Apparently some of the ponds are already leaking into the river.

Meanwhile on the other side of the world in Australia:

Designing an emissions trading scheme in Australia was supposed to have been made easier by the pioneering work done in the European Union. After all, they’ve been developing their scheme since 2000 and trading for nearly four years, albeit with varied success.

But there’s a big catch. The EU hasn’t worked out how to treat its emissions-intensive trade-exposed (EITE) industries and find an equitable system for auctioning permits. Under pressure from business concerned about the erosion of their international competitiveness, the EU avoided any tough decisions on permits, simply allocating them to major emitters or applying grandfather clauses since the first trial period began in 2005.

Environmentalists derided the approach and the over-generous allocations that followed, but the underlying structural problem is genuine. The accumulation of greenhouse emissions is a global problem, but any domestic emissions trading scheme will make firms inside its borders less internationally competitive, and will just relocate many trade-exposed emissions from regulated to unregulated economies. [added emphasis–JR]

This article goes on to quote a study by the Business Council of Australia that “tested the impact of a carbon price of $40 a tonne on 14 trade-exposed firms.” (This is a extremely low price for carbon that translates into a price of less than $11 a ton for CO2. A price that would get us moving toward serious carbon reduction would probably need to be at least 10 times higher.) The study concluded that:

…without any compensation, four would close, three more would have to take drastic action and might also fail, while the remaining seven would lose more than 10 per cent of profits. Remedial action for all firms would result in significant carbon leakage to other economies.

I have serious doubts about the accuracy of the Business Council of Australia’s calculations. Nevertheless the fear that any country that imposes strict emissions standards on it’s most polluting, energy-intensive industries will either see those industries go bankrupt or pack up and move to some place without regulations is widespread.

Canada’s decision to exploit its tar sand resources and the failure of Cap and Trade in Europe to set an adequate price for carbon highlight what happens when there is a lack of international agreement about confronting Climaticide. The failure of the United States to sign the Kyoto Treaty and to seriously participate in the ensuing negotiations about further emissions cuts has undoubtedly been a major contributor to both of these policy failures.

What are the lessons that President Obama and Vice-President Biden should draw from this?

1) Without international agreements, all attempts to confront Climaticide are doomed to failure. No country is going to establish emissions limits on its most energy intensive, most polluting industries, if it sees large economic losses as the consequence. Without United States leadership, the establishment of a world-wide enforceable and effective Cap, Auction and Trade policy will never happen. Developing countries such as China and India will only join such a system if the developed world embraces it unanimously.

Additionally, a plan must be adopted to transfer sustainable energy technology and programs for energy efficiency to the world’s most impoverished nations at little or no cost to them. Both practical considerations (including putting an end to deforestation and sponsoring both reforestation and afforestation) and justice require that these countries be given an opportunity for development that does duplicate and exacerbate the errors committed by the developed world.

2) The energy crisis cannot be addressed outside of the context of the climate crisis. Attempts to achieve energy independence or to alleviate high energy costs that ignore the question of greenhouse gas emissions will only worsen our problems and make it less likely that we will be able to avoid catastrophic climate tipping points.

Specifically, international agreement needs to be reached banning:

a. all new coal-fired power plants that do not provide Carbon Capture and Sequestration (CCS),which at the present time means NO new coal-fired power plants.

b. any exploitation of oil from tar sands or oil shale.

c. offshore oil exploitation in newly ice-free Arctic waters.

Free market advocates have argued that high energy prices will lead to innovation that will fix the problem, but without international agreement on emissions policy, higher energy prices will only lead to the exploitation of the most dangerous remaining fossil fuels and uncertainty and delay in the adoption of real cap, auction and trade policies. We can afford neither.

Check out this new post by Joe Romm on why, even with US leadership, attainment of these goals is going to be extremely difficult.

The North Pole Today, 24 August 2008

Well, this past week has been interesting up at the North Pole webcams. It’s been below freezing much of the week, with a temperature as low as – 8°C (about 18°F), and North Pole webcam #1 has an iced-up lens this a.m., as it has for the last several days:

55 UTC

The temperature is about 26°F (-3°C) at 7:55 Universal Time today.

Webcam #3 is clear though (I think it’s heated from inside), and appears as so at 10:11 Universal Time today:
11 UTC
I honestly don’t know what the normal temperature is at the North Pole during the third full week of August, but there is information on normal and current Arctic sea ice cover:
Arctic sea ice extent (at least 15% coverage in 25 km2 grid boxes
Interestingly, this illustrates the “point” climate scientists often make, that one point does not a season (or trend, anomaly, and so on) make; the sea ice extent in the Arctic took another dive this past week, while the North Pole itself got rather cold. Winds may have driven this as well by pushing ice north; the pattern north of AK and the Bering Sea, however, bears out melting rather than pushing around of ice (see table of graphics below). Climatology for sea ice concentration and extent from 1953-1991 is shown alone in the bottom row; as we’ve seen, current (and of course, 2007) sea ice concentrations and extent continue well-below normal.

Arctic sea ice concentration, 8/24/08 color legend, % concentration Arctic sea ice concentration, 8/24/07
Arctic sea ice concentration/extent, 24 August 2008 Photobucket arctic sea ice, 24 August 2007, 2007 melt season

Arctic sea ice concentration, 17 August 2008 Photobucket Arctic sea ice concentration, 17 August 2007
Arctic sea ice extent/concentration climatology, based on 1953-1991 data set

Well, it looks like my relatively well-informed (I know earth science, after all) prediction of where the sea ice would disappear from last week was pretty good. I’m too lazy this week to annotate the current week concentration graphic, but you can bet that the areas in red, orange and yellow are at risk going into next week.

We have about 2-3 more weeks of potential melt at this point before the 2008 freeze-up begins. Current weather is shown in the graphic below. Temperatures near the pole are currently below freezing as low as −7°C (about 20°F) as can be seen in the graphic of 12 Universal Time 24 August 2008 weather conditions (temperatures only for Arctic Ocean generally, though):

Arctic weather, 12 UTC 24 August 2008

Sea surface temperatures (SSTs) in the Northwest and Northeast quandrants of the Northern Hemisphere appear below. We still have the pattern of above normal SSTs along the North American and Siberian Arctic Ocean coasts; below normal temperatures where the meltwaters from the Greenland Ice Sheet appear:

Sea surface temperature anomalies, NW quadrant of earth, 23 August 2008, °C
Sea surface temperature anomalies, NE quadrant of earth, 23 August 2008, °C

I’m awaiting the next report from the National Sea Ice Data Center on their observations and expectations for the remainder of the ice melt season. Should be interesting.

An Open Letter to the New York Times’ Andy Revkin

Before reading this letter, I recommend that the reader read Andy’s piece (and the comments on it) at the New York Times.

Dear Andy,

I’m going to be blunt. This post is a perfect example of why I have so little respect for you as a writer on global warming. Your wishy-washy prose and, worst of all your, failure to provide any context (and I know that you are perfectly aware of the context) for your stories make you a great source of comfort for the denialist ideologues and ignoramuses who frequent this site.

It is a fact that polar bears can spend long amounts of time in the sea and swim long distances. Historically, they have swum between chunks of sea ice, which they hunt from. One doesn’t need to do years of studies to understand that the huge summer sea ice melt of the last few years inevitably makes their lives harder, because there is less ice, it is farther from shore and the distances to be swum are greater. Are the bears drowning in greater numbers? We don’t know yet, but simple logic says that we ought to entertain the possibility and do the research.

But the big story in the Arctic isn’t the polar bears. It’s the rise in temperature and the melting of the ice and permafrost and the feedbacks from reduction of the earth’s albedo and the potential for methane release. Denialists want to talk about polar bears precisely because they don’t want to talk about these other issues where the evidence is irrefutable.

See my post, Temperatures Hit 80 Degrees in the Arctic: 2008 May See a Record Sea-Ice Melt After All, on this topic at

Temperatures Hit 80 Degrees in the Arctic: 2008 May See a Record Sea-Ice Melt After All

You write:

In the meantime, the latest news will serve, I’m sure, to heat up the climate fight, providing powerful imagery for climate campaigners and more ammunition for foes of greenhouse gas restrictions who argue that such imagery belies the marine mammals’ resiliency in both watery and frozen seas.

Explain to me, if you can, how the latest news provides ANY ammunition for foes of greenhouse gas restrictions. It may not provide evidence for those concerned about Climaticide (although it raises questions), but it provides N0 support for the denialist position.

Is it the faux sense of “balance” that hobbles the Traditional Media, which makes you write so tentatively that you end up distorting the truth? To report facts out of context is to enable people who have no real interest in facts at all, and, frankly, not much better than publishing out-and-out lies (which, by the way, you let people do in your comments section all the time).

Sincerely,

Johnny Rook

“The American West’s canary in the coal mine”

For Peggy Sue Smith, who introduced me to pikas Pika

If you hike in the mountain west, chances are that at one time or another, probably while crossing a talus slope, you have heard, if not necessarily seen, a pika. These shy creatures with their bunny-like cuteness (the two creatures are relatives), live camouflaged among the rocks and feed on alpine flowers. Unfortunately, due to rising temperatures at higher elevations caused by global warming (they currently live, on average, 900 higher feet than in the past) over a third of the known populations in the Great Basin region of Oregon and Nevada has gone extinct.

With temperatures in the west expected to rise at double last century’s rate, little pika habitat will remain by the end of the century.

pika 2

Today, Earthjustice Legal Defense Fund announced that, in conjunction with the Center for Biological Diversity, it was filing two lawsuits, one (PDF) against the California Fish and Game Commission for denying a peition to protect the pika from the effects of global warming and another (PDF) against the United States Fish and Wildlife Service for failing to protect the pika under the Endangered Species Act. In October, the Center for Biological Diversity filed a separate petition with the U.S. Fish and Wildlife Service, which, by law, was to have responded within 90 days, but in a move reminiscent of the recent foot-dragging on ESA status for polar bears, Fish and Wildlife broke the law by failing to issue a response by the deadline.

From the Earthjustice web site:

Conservation groups filed two lawsuits today seeking protection of the American pika, whose survival is imperiled by global warming. The groups went to state court seeking protection of the pika under the California Endangered Species Act and to a federal court seeking protection under the federal Endangered Species Act.

The American pika, Ochotona princeps, is a small relative of the rabbit whose squeaky calls are a familiar companion to alpine hikers. Pikas live in boulder fields near mountain peaks in the western United States. Adapted to cold alpine conditions, pikas are intolerant of high temperatures and can die from overheating when exposed to temperatures as low as 80°F for just a few hours.

“The pika is the American West’s canary in the coal mine,” said Shaye Wolf, a biologist with the Center for Biological Diversity. “As temperatures rise, pika populations at lower elevations are being driven to extinction, pushing pikas further upslope until they have nowhere left to go.”

Unwillingness, to protect the pika is, of course, simply part and parcel of the Bush Administration’s attempts to evade the requirements of the Endangered Species Act because of its fear that complying with the ESA will force it to regulate greenhouse gas emissions, negatively impacting the profits of its cronies in the petroleum and coal industries.

As Daily Kos blogger Patriot Daily News Clearinghouse has explained:

Bush is killing Endangered Species law (ESA) by a proposed administrative rule because he does not want ESA to be “used as a back door” to regulate GHG. Thus, Bush is using a back-door administrative process to change the law because similar attempts to obtain legislation from Congress failed. Bush’s new rule would hasten the extinction of many species by wiping out the independent scientific review currently used to determine harmful impacts on species and replacing it with a unilateral government review devoid of scientific data. It’s an approach of ignorance is blissful for profits. After all, it was the scientific data which compelled the conclusion for the first time that climate change impacts may trigger listing a species as threatened, which recently happened with the polar bear. Moreover, Bush knows his proposed rule is illegal because a court rejected a similar rule a few years ago.

Pika on rock

What are you people, stupid, or something?

[Hat tip to GW Chimpzilla at Daily Kos for the following video]

The idea of abrupt climate change is only slowly making its way into the popular mind. Although scientists have been aware for over two decades that climate can lurch quickly from one state to another, geological speaking, the average person still has difficulty in imagining climate changing in anything less than millions or thousands of years or perhaps, at best, centuries. This is undoubtedly one of the reasons that many people still fail to feel any sense of urgency about Climaticide.

Abrupt climate change has been discussed by such science writers as John D. Cox in Climate Crash: Abrupt Climate Change and What It Means for Our Future and Fred Pearce in With Speed and Violence: Why Scientists Fear Tipping Points in Climate Change. Cox describes the discovery of abrupt climate change while Pearce writes of possible abrupt future climate change as a result of global warming.

However, new research now indicates that climate may change even faster than anyone imagined.

It is generally accepted that that the last glacial period began about 110,000 years ago and ended around 15,000 BP.

According to Wikipedia:

The last glacial period is sometimes colloquially referred to as the “last ice age”, though this use is incorrect because an ice age is a longer period of cold temperature in which ice sheets cover large parts of the Earth. Glacials, on the other hand, refer to colder phases within an ice age that separate interglacials. Thus, the end of the last glacial period is not the end of the last ice age. The end of the last glacial period was about 12,500 years ago, while the end of the last ice age may not yet have come: little evidence points to a stop of the glacial-interglacial cycle of the last million years.

The maximum extent of glaciation during the last glacial period occurred around 18,000 years ago. After that the earth began to warm and the great ice sheets to retreat. Temperatures eventually reached levels similar to those we experience today. Then, suddenly, around 13,000 years ago temperatures dropped and ice sheets resumed their expansion. This period, known as the Younger Dryas, after an alpine/tundra flower common at the time, lasted for approximately 1,000 years.

Dryas octopetala

There is disagreement about what caused the Younger Dryas period. The traditional interpretation is that it was caused by a shutdown or weakening of something called the thermohaline circulation or ocean conveyor. This phenomenon is also sometimes called, incorrectly, the meridional overturning circulation (MOC). For our purposes here, the differences between the two concepts are irrelevant.

In very simplistic terms what supposedly happens is this: surface currents from the tropics carry warm water north to Northern Europe where the water is cooled by northern winds, which also cause evaporation and make the water saltier (i.e. denser). This colder, saltier water then sinks into the deep ocean and returns southward. A more detailed description is available at the Wikipedia link immediately above. An important byproduct of the thermohaline circulation is that the U.K. and Northern Europe enjoy warmer temperatures than they would otherwise. (Compare the temperatures at similar latitudes in North America.)

Thermohaline Circulation

This interpretation, however, is not universally accepted. Wikipedia summarizes the state of the dispute as follows:

The thermohaline circulation plays an important role in supplying heat to the polar regions, and thus in regulating the amount of sea ice in these regions. Changes in the thermohaline circulation are thought to have significant impacts on the earth’s radiation budget. Insofar as the thermohaline circulation governs the rate at which deep waters are exposed to the surface, it may also play an important role in determining the concentration of carbon dioxide in the atmosphere. While it is often stated that the thermohaline circulation is the primary reason that Western Europe is so temperate, it has been suggested that this is largely incorrect, and that Europe is warm mostly because it lies downwind of an ocean basin, and because of the effect of atmospheric waves bringing warm air north from the subtropics.[3] However, the underlying assumptions of this particular analysis are not generally supported,[4] and much research supports the role of the THC in transporting heat to Europe.[5]

Large influxes of low density meltwater from Lake Agassiz and deglaciation in North America is thought to have led to a disruption of deep water formation and subsidence in the extreme North Atlantic and caused the climate period in Europe known as the Younger Dryas.[6]

Recent research by a team lead by Achim Brauer of the German Reseach Institute Centre for Geosciences and published on August 1, 2008 in Nature Geoscience (subs. required) with the title, An abrupt wind shift in western Europe at the onset of the Younger Dryas cold period, advances a different theory.

Lake Meerfelder Maar

Brauer’s team analyzed the varves from Lake Meerfelder Maar in western Germany. The varves in the lake, which is situated deep within a volcanic crater, contain a continuous temporal record that extends through the Younger Dryas. Brauer believes, based on geochemical and other analyses of the varves that changes in sea ice extension chilled the Northerly winds, which in turn affected the temperature of ocean currents and produced the dramatic temperature drop and growth of glaciers that marked the Younger Dryas.

It is well beyond my expertise to evaluate the merits of the competing theories, and I shall not attempt to do so. What I do want to highlight however is the degree of precision that Brauer’s team was able to obtain in dating the onset of the Younger Dryas.

According to Brauer’s paper:

With the onset of the Younger Dryas cold period, the formation of thick monospecific diatom layers (Stephanodiscus sp.) during spring/summer is explained by an increase in the wind-driven upward mixing of nutrient-rich bottom water. The reworked sediments argue for a major fall in lake level and an increase in wave activity at the shoreline due to windy conditions. Particularly striking are the pronounced inter-annual to decadal oscillations before the final shift, which occurred within one year. These short term fluctuations indicate that the change from calm and wet to windy and dry conditions began with a period of individual extreme years with Younger-Dryas like-conditions. However the depositional system in the lake switched back after these extreme years to Allerød-like conditions until the permanent shift at 12,679 varve year BP [emphasis-JR]

.

In other words, after some years of erratic weather a tipping point was passed and in a single year norther Europe went from temperatures similar to those we now experience to glacial conditions. Temperatures at the summit of Greenland plummeted to 15C less than today.

Dr. Brauer’s research is worth remembering the next time that you are talking with a climate denialist/delayer who is arguing that we need to do more research before we decide what to do about Climaticide. We now know that the earth’s climate is capable of making dramatic long-lasting jumps within extremely short time frames. It has already happened.

We could get lucky… Maybe it won’t happen again…

But wouldn’t it be wiser to take action now to cut our emissions and eventually rollback levels of greenhouse gases which we know are heating up the planet and destabilizing the climate? Or do we want to cross our fingers, continue to point the gun at our head and and hope each time we pull the trigger (which is what we do every year that we postpone dealing with Climaticide) that the chamber beneath the firing pin is one of the empty ones?

As the New York Times’, Thomas Friedman, Daily Kos’s A. Siegel, and Climate Progress’s Joseph Romm, have all pointed out, there are a lot of lies coming from John Mccain’s BS Express, particularly as regards alternative energy policy and McCain’s support of it. See the following for more information.

Eight Strikes and You’re Out

McCain: Liar, Liar, Pants on Fire …

McCain: Simple, Direct, Deceitful

The real, Luddite McCain: “The truly clean technologies don’t work”

Speech, Part 1: Anti-wind McCain delivers climate remarks at foreign wind company

Why McCain hates renewables but pretends he loves them

Will McCain’s cynical lies destroy the chance for serious energy and climate policy?

The video below shows McCain clearly lying about his voting record on renewable energy. (Click the links above for to see the evidence of McCain’s lies.)

And as this video makes evident, he doesn’t even take renewable energy seriously.

So, why does Straight-Talker McCain run ads filled with windmills and solar panels and claim that he supports renewable energy when he neither believes in it or votes for it?

That’s a question that I would like to hear him asked by the Traditional Media and not just once. He needs to be asked until he gives us a straight answer. Unfortunately, no one in the Traditional Media insists on getting a straight answer to their questions anymore. The interviewer asks a question, the person being interviewed says whatever they feel like, and then interviewer goes on to the next question. Maybe this is why John Stewart of the Daily Show is The Most Trusted Man in America.

The Ice Continues to Melt: Two Greenland Glaciers Breaking Up

The 2008 ice melt continues. Researchers at Ohio State University’s Byrd Polar Research Center have announced that satellite photos reveal that an 11 square mile piece of ice (about half the size of Manhattan) broke off Greenland’s Petermann Glacier in late July of this year. The breakup actually took place just a few days before the collapse of 7 square miles of the Ward Hunt ice shelf off Ellesmere Island west of Greenland that I reported on previously.

In the July 25th MODIS satellite image below you can clearly see that a large chunk has broken away from the glacier’s upper left-hand corner.

Petermann Glacier breakup

Even more worrisome, according to Ohio State University geographer, Jason Box, is the presence of a crack farther up the glacier’s tongue.

“If the Petermann glacier breaks up back to the upstream rift, the loss would be as much as 60 square miles (160 square kilometers),” Box said, representing a loss of one-third of the massive ice field.

Petermann Glacier crack August 2008

Since the tongue is an ice shelf (meaning that the ice is already floating), the breakup will not directly contribute to sea-level rise, but as research on the Larsen B ice shelf in the Antarctic has shown, the demise of ice shelves, which often serve as breaks on the ice fields behind them, can accelerate the speed of ice field movement. In the case of the Larsen B the speed increased by between 3 and 8 times.

Meanwhile, the margin of the Jakobshavn Glacier on Greenland’s southwest coast has retreated to a point never before seen in 150 years of observations and perhaps where it has not been in 4,000 to 6,000 years.

The Northern branch of the Jakobshavn broke up in the past several weeks and the glacier has lost at least three square miles (10 square kilometers) since the end of the last melt season.

The Jakobshavn Glacier dominates the approximately 130 glaciers flowing out of Greenland’s inland into the sea. It alone is responsible for producing at least one-tenth of the icebergs calving off into the sea from the entire island of Greenland, making it the island’s most productive glacier.

Jakobshaven Glacier August 2008

The retreat of the Jakobshavn’s margin has already sped up the glaciers flow. Between 1997 and 2003 the glacier doubled its speed. with significant consequences for sea-level rise.

Jakobshavn Isbrae is Greenland’s largest outlet glacier, draining 6.5 percent of Greenland’s ice sheet area. The ice stream’s speed-up and near-doubling of ice flow from land into the ocean has increased the rate of sea level rise by about .06 millimeters (about .002 inches) per year, or roughly 4 percent of the 20th century rate of sea level increase.

Also, the rapid movement of ice from land into the sea provides key evidence of newly discovered relationships between ice sheets, sea level rise and climate warming.

The researchers found the glacier’s sudden speed-up also coincides with very rapid thinning, indicating loss of ice of up to 15 meters (49 feet) in thickness per year after 1997.

Research presented at last year’s meeting of the American Geophysical Union by Box and graduate student Adam Herrington, showed that the glacier behaved in a similar fashion in the 1920’s during another period of rising temperatures. However the situation now is more worrisome because of global warming:

The fact that recent changes to Greenland’s ice sheet mirror its behavior nearly 70 years ago is increasing researchers’ confidence and alarm as to what the future holds. Recent warming around the frozen island actually lags behind the global average warming pattern by about 1-2 degrees C but if it fell into synch with global temperatures in a few years, the massive ice sheet might pass its “threshold of viability” – a tipping point where the loss of ice couldn’t be stopped.

“Once you pass that threshold,” Box said, “the current science suggests that it would become an irreversible process. And we simply don’t know how fast that might happen, how fast the ice might disappear.”

A complete melting of the Greenland ice sheet, although not considered an immediate threat, (in reality, as mentioned above, scientists are uncertain about what the rate of melt might be if a tipping point were reached) would raise the level of the world’s oceans by over 20 feet.

Greenland melt days 2005

Warmer temperatures are increasing the number of summer days when portions of the surface of the Greenland Ice Sheet melt. Along the margins of the ice sheet, up to 20 additional days of melting occurred in 2005 compared to the average since 1988. (NASA map by Robert Simmon and Marit Jentoft-Nilsen, based on data from Marco Tedesco, GSFC.)

For a fascinating account of how scientists have determined that the Greenland ice sheet as a whole is losing mass see this Earth Observatory article here.

David Roberts at Grist and Matt Stoller at Open Left have given Al Gore and We Can Solve It grief of late for not taking a hard enough stance against the wingnuts in their campaign to stop Climaticide. One of their complaints had to do with an early We Can Solve It ad that they thought gave green cred to right wing scumbag Newt Gingrich. Maybe Gore was listening. This new ad definitely hits a better tone.

“We DEMAND that we use them.”

Yes! This is how WE we all need to be talking. We’re not asking any more. Kudos to Al Gore and the We Campaign for getting it right this time.

Each new ad has been better than the last. Here are two earlier ones from the campaign. The last one is the one that so ticked off Roberts and Stoller (not without reason).

North Pole today, 17 August 2008

NOTE: crossposted at Daily Kos.

This week, the camera direction at NOAA webcam #1 was moved once again to a position similar to when I started doing these diaries in early July. There was no still image from the camera today; the last one was from 22:25 UTC yesterday, 16 August 2008. Temperature at that time was -2°C, and it appeared there was some ground fog beneath a generally clear sky.

25 16 August 2008

I’ve also included an image from today from the “fisheye” lens webcam #3, taken 20:16 UTC, below.

NOAA North Pole webcam #3

Note the hoarfrost on the pole to the right and the precipitation gauge to the left. It’s been colder this past week in the Arctic, at least the part where these webcams are located.

Colder weather notwithstanding, Arctic sea ice loss continues at the same pace as last season, though the amount of coverage is still greater than in 2007. This can be seen in the graphic below:

Arctic sea ice extent, area greater than 15% sea ice

Eyeballing the figure shows that coverage is at about 6 million km2; last year that level was reach about 5 August, so we’re about 12 days behind that season. If the ice melt rate reverted back to the normal rate (bold gray line), coverage would bottom out at about 5.5 million km2, which would put the 2008 minimum at third lowest behind 2005 and 2007. That might be considered the best case scenario. If ice melt goes at the same rate as last year, on the other hand, minimum sea ice extent will probably reach about 5 million km2, which would result in a second-least ranking behind last year.

Large areas of the Arctic Ocean have relatively low concentrations of sea ice (50% or less) as can be seen in the upper left graphic in the table below (yellow-green to red).

What’s the future hold? Normally, the ice melt season ends in early September, as we see the average minimum appears at that time. With an extended ice melt season as has been seen in recent years, ice melt probably won’t end until mid-to-late September. How that will evolve, and how low we will go in 2998, will depend on the weather over the next month. What did the full Arctic look like today? Here’s a graphic from the University of Cologne (Germany) showing air temperatures at the crosses over the Arctic Ocean (not bad coverage considering):

Temperature are in °C. Most are within a degree or two either side of 0°C, with darker blue from 0 to -2°C, lighter blue from 0 to +2 or so °C.

Finally, here are the western hemisphere sea surface temperature anomalies as of today, 17 August 2008. Note how warm the Arctic Ocean is north of AK and how warm Hudson’s Bay is (as much as +5°C above normal). The colder-than-normal water around Greenland is the result of fresh water ice melt from the Greenland ice sheet; it’s been a prominent feature now for a number of years in boreal summer.

You might be surprised to find out that despite being the number three wind producer in the world, Spain is dead last among developed countries in meeting its Kyoto targets. In this post we’ll take a look at how that happened and why Spain (and the rest of the United States) needs a dose of Californication.

According to the 1997 Kyoto Protocol, the European Union is to cut its emissions of greenhouse gases by 8% relative to 1990 levels by the period 2008-2012. Because at the time the agreement was signed, Spain was considered one of the less developed economies (it currently ranks 5th) among the then 15 European Union members (there are currently 27), its emissions target was set at a 15% rise over 1990 levels. (Greece, Ireland and Portugal were also allowed to grow their emissions.)

However, as of 2007, Spain is 52.3% above its Kyoto target and despite optimistic government promises that it can still meet the target it seems extremely unlikely that the Spanish will be able to reduce emissions by 35% relative to 1990 levels in only 4 years.

It is common to hear reference to Spanish wind power in conversations about global warming and energy independence. The Spaniards have grown wind power to nearly 9% of their electrical mix and Spanish companies are busy selling wind technology around the world including in the United States. But wind is only a small part of the Spanish energy story, albeit the most successful.

Part of Spain’s problem is that it has been so successful economically. This has led to increased energy usage. According to a report (PDF in Spanish), Evolution of Greenhouse Gas Emissions in Spain (1990-2007), compiled by the Spanish labor union Comisiones Obreras and the Spanish-language version of World Watch magazine the sectors experiencing the most growth in emissions are electricity generation and transportation. Emissions from electricity generation (up 66% since 1990) account for 24.3% of total Spanish emissions while emissions from transportation (up 97% since 1990)are responsible for 22.9%.

Until very recently the Spanish economy was growing rapidly, largely based on a boom in the construction industry which is very electricity intensive. Around 800,000 new homes were constructed in Spain last year, more than France, Germany and Britain combined and Spain was the second largest market for cement in the world after China. (Cement production is itself a significant source of GHG emissions accounting for 5% of emissions worldwide.) Many of the houses were constructed in coastal or island regions (link in Spanish) which cater to the enormous Spanish tourist industry.

Only this year has the government approved new building codes requiring that new homes be more energy efficient with better insulation and solar panels on every roof. AS Socialist party Environment Secretary Soraya Rodriguez put it “Up to now, we’ve been using 1970s building standards.”

Changing rules regarding housing and transportation can be politically tricky however. Witness the ongoing furor over gas prices and drilling in the United States.

CO2 emissions from households and transport are difficult to stabilise without politically unpopular measures such as restricting cars in city centres or hiking electricity prices.

Javier Tordable, managing director of the Barcelona-based carbon exchange Sendeco2, says the trend is towards obliging makers of household appliances and cars to price in the CO2 their goods will produce.

“As more sectors are included, the national CO2 allocation plan will be easier to manage,” he says. “Liberalising Spain’s electricity industry so that it no longer has to sell power below cost will be another major step.

Surveys show Spanish consumers are gradually becoming more environmentally conscious, but they are still among the most wasteful in Europe and the most prone to take out their cars for short journeys.

But transportation is a problem throughout the European Union:

A surge in transport in the European Union is jeopardizing goals for cutting greenhouse gases blamed for global warming, the European Environment Agency (EEA) said on Monday.

Emissions from transport, led by a near-doubling in aviation traffic, rose on average by 25 percent across Europe from 1990-2004 even as most EU nations managed to cut emissions from other sectors such as industry or agriculture.

“The environmental performance of the transport sector is still unsatisfactory,” the EEA said in a report covering EU nations along with some details of outsiders Turkey, Switzerland, Norway, Iceland and Liechtenstein.

“This tendency threatens both Europe’s and individual EU member states’ progress toward their … targets” under the U.N. Kyoto Protocol, it said in a 44-page report. “Therefore, additional policy initiatives and instruments are needed.”

“Transport — bottom of the Kyoto class again,” it said.

Transport, based mainly on burning oil, accounts for about a fifth of European emissions of heat-trapping gases from human activities. Cars and trucks account for more than 90 percent of transport emissions, ahead of ships, planes and trains.

From 1990-2003, passenger transport volumes in Europe grew by 20 percent, the EEA said. More people own cars and often drive further, for instance to out-of-town shopping malls. Air transport alone surged by 96 percent, aided by cheaper flights.

If Spain fails, as it most surely will, to cut its emissions by 35% relative to 1990 before 2012 it will cost the country around 4 billion Euros, as it will have to purchase carbon credits from nations which have been successful in reducing their emissions.

“They’re looking at a huge bill now,” said Mike Rosenberg, management professor at the University of Navarra’s IESE Business School in Barcelona. “That is because none [referring to Spain, Ireland and Japan-JR] would pay to reconvert factories, power plants and paper mills” to trim gases blamed for the planet-warming “greenhouse effect.”

The cost of a permit to spew a ton of CO2 into the skies surged this year after evidence of global warming mounted and European states reacted by restricting the supply of allowances. The price for a 2008 certified emission-reduction credit rose 14 percent in the three months through Nov. 27 to a record 18.20 euros ($26.85) to release a ton of CO2, according to Nord Pool ASA power exchange prices on Bloomberg.

To summarize, despite the growth of wind power in Spain, the country’s emissions have continued to grow (without the increase in wind power, however, last year Spain would have emitted an additional 26 million tons of CO2). Rapid economic growth has spurred demand for electricity, which has grown 63.4% since 1990, in absolute terms far beyond what the new wind power can offset. As nuclear power and hydroelectric power have stayed the same or dropped (due to drought in the case of the latter) the remaining power has had to come from fossil fuels, which still make up 50% (more if you include cogeneration plants using fuel oil and gas oil) of the Spanish energy mix.

So, what did the Spanish do wrong? Their biggest error was a lack of political will. They ignored non-sexy energy efficiency, focusing instead on alternative energy production and treeplanting as the vehicles for meeting their Kyoto obligations. This lack of energy efficiency in Spain is a focus of the Comisiones Obreras-World Watch report {PDF in Spanish], which calls for the passage of an Energy Efficiency Law applicable not only to new construction but also providing for the retrofitting of older buildings as well as for new, higher standards in lighting, appliances, etc. The reports authors also call for greater fuel efficiency for automobiles and a transition first to hybrids and then to electrical vehicles.

If the Spaniards seriously want to tackle their greenhouse gas emissions they could find the perfect model in one of their former colonies, the US state of California. California is about 80% the size of Spain in both area and population, yet while Spanish economic growth has been produced at a very high price in energy consumption and greenhouse gas emissions, California has has kept per capita energy consumption level for three decades. While the US federal government has shown not merely a lack of political will but a hostility to takng action on Climaticide, California has moved ahead on its own, often having to take on the Bush administration as in the case of automobile fuel efficiency.

Joseph Romm has written about California as a model not for Spain, but for the rest of the United States.

How big is the efficiency potential in this country? The global consulting firm McKinsey & Co. estimates that nearly 40% of the U.S. emissions reduction potential by 2030 is from energy efficiency (see here).

In the past three decades, electricity per capita has stayed flat in Californian while it has risen 60% in the rest of the country. If all Americans had the same per capita electricity demand as Californians, we would cut electricity consumption 40%. And if all of America adopted the same energy efficiency policies that California is now putting in place, the country would never have to build another power plant.

Energy efficiency is THE core climate solution.

Not only has California kept per capita demand flat it has done it more cheaply than it ever could have by building more power plants of any kind.

California has cut annual peak demand by 12 GW — and total demand by about 40,000 GWh — over the past three decades. The cost of efficiency programs has averaged 2-3¢ per kW — which is about one fifth the cost of electricity generated from new nuclear, coal and natural gas-fired plants. And, of course, energy efficiency does not require new power lines and does not generate greenhouse gas emissions or long-lived radioactive waste.

So why isn’t this being done everywhere? In the United States and in Spain? It may not be sexy, but it works.

Many of the strategies are obvious: better insulation, energy-efficient lighting, heating and cooling. But some of the strategies were unexpected. The state found that the average residential air duct leaked 20 to 30 percent of the heated and cooled air it carried. It then required leakage rates below 6 percent, and every seventh new house is inspected. The state found that in outdoor lighting for parking lots and streets, about 15 percent of the light was directed up, illuminating nothing but the sky. The state required new outdoor lighting to cut that to below 6 percent. Flat roofs on commercial buildings must be white, which reflects the sunlight and keeps the buildings cooler, reducing air-conditioning energy demands. The state subsidized high-efficiency LED traffic lights for cities that lacked the money, ultimately converting the entire state.

And energy efficiency doesn’t just work as public policy. It also works as company policy. One of the most inspiring examples that Romm gives of the benefits of energy efficiency comes from an otherwise uninspiring source–Dow Chemical:

You might have predicted that by 1982, after two major energy shocks, if any company in the country had captured the low-hanging fruit of energy savings, it would be one as energy intensive as a world-class chemical manufacturer. Nonetheless, energy manager for the [Dow’s Louisiana] division’s more than 20 plants, Ken Nelson, began a yearly contest in 1982 to identify and fund energy-saving projects. His success was nothing short of astonishing.

The first year had 27 winners requiring a total capital investment of $1.7 million with an average annual return on investment (ROI) of 173%. After those projects, many in Dow felt that there couldn’t be others with such high returns. The skeptics were wrong. The 1983 contest had 32 winners requiring a total capital investment of $2.2 million in a 340% return – a savings of the company’s $7.5 million in the first year and every year after that.

Even as fuel prices declined in the mid-1980s, the savings kept growing. Contest winners increasingly achieved the economic gains through process redesign to improve production yield and capacity. By 1988, these productivity gains exceeded the energy and environmental gains. The average return to the 1989 contest was the highest ever, an astounding 470% in 1989, 64 projects costing $7.5 million saved the company $37 million a year — a payback of 11 weeks.

Finally, Romm offers a plan for energy efficiency that would benefit the United States or Spain if either were to adopt it:

We should establish a federal matching program to co-fund state-based efficiency programs, with a special incentive to encourage states without an efficiency program to start one. This was a key recommendation of the End-Use Efficiency Working Group to the Energy Future Coalition, a bipartisan effort to develop consensus policies, in which I participated. The first year should offer $1 billion in federal matching funds, then $2 billion, $3 billion, $4 billion, and finally stabilizing at $5 billion. This will give every state time to change their regulations and establish a learning curve for energy efficiency.

This program would cost $15 billion in the first five years, but save several times that amount in lower energy bills and reduced pollution. Since the next president will put in place a cap-and-trade system for greenhouse gases, the revenues from auctioning the emissions permits can ultimately be used to pay for the program.

We should restore a federal focus on the energy-intensive industries, such as pulp and paper, steel, aluminum, petroleum refining and chemicals. They account for 80 percent of energy consumed by U.S. manufacturers and 90 percent of the hazardous waste. They represent the best chance for increasing efficiency while cutting pollution. Many are major emitters of greenhouse gases other than carbon dioxide. A 1993 analysis for the DOE found that a 10 to 20 percent reduction in waste by American industry would generate a cumulative increase of $2 trillion in the gross domestic product from 1996 to 2010. By 2010, the improvements would be generating 2 million new jobs.

Focusing on saving energy in the pulp and paper industry etc. may not seem very exciting at first glance, but you never know what a country might do to pick up an easy extra trillion bucks (and cut greenhouse gas emissions at the same time)–“Oh baby…, I love it when you talk efficiency to me.”
