Dr. James Hansen, the world famous climatologist from NASA’s Goddard Institute for Space Studies (GISS) has declined to throw his support behind UK protesters organizing against a 3rd runway at Heathrow Airport. In the past Dr. Hansen has lent his considerable scientific weight in support of anti-coal protesters such as the Kingsnorth Six at whose trial he offered both written and oral testimony.
In explanation of his decision, Dr. Hansen offered the following comments:
“I don’t think it is helpful to be trying to prevent air flight,” Hansen told the Observer.
“Coal is 80% of the planet’s problem,” he said. “You have to keep your eye on the ball and not waste your efforts. The number one enemy is coal and we should never forget that.”
“The number of runways you need for your airports depends on their traffic. You don’t want to be so restrictive that you end up burning more fuel because planes are having to circle and wait to land because of lack of runway space.”

Tough one. England has a closer relationship to coal than the US.
Pick your battles.
First action is to stop denialism and lying about the true cost of using coal.
