Bill McKibben — author, climate activist, and founder of 350.org — is in the midst of a 21-city “Do the Math” tour to build grassroots support for combating climate change. The target of the campaign is the fossil fuel industry, and McKibben and 350.org are calling for universities, colleges, and governments to divest themselves of oil and coal company assets. (more…)

On whether Obama’s re-election and the aftermath of Sandy represent a moment for climate change action

I think it definitely is a time when more and more people are focused on the extreme weather that has disrupted so many lives. People who have not really devoted a lot of time to thinking about the climate (more…)

Climate change received scant attention in the election campaign. But with public concern about global warming growing in the wake of Hurricane Sandy, President Obama has an unprecedented opportunity to take bold action on climate and clean energy.

A new modeling study by several geoengineering experts suggests that injecting aerosols into the atmosphere to block more of the sun’s energy and reduce temperatures could be most effective when done on a region-by-region basis.

The study, published in the journal Nature Climate (more…)
