Fossil fuel subsidies up, nuclear power down: IEA

Market-distorting fossil fuel subsidies rose 30% from 2010 to 2011, stymying efforts to boost the renewables sector and reduce greenhouse emissions worldwide, a new global report has found. The 2012 World…
Global energy use must grow substantially every year to keep up with population - our decarbonisation efforts aren’t making inroads. Carolyn Chan

Methane locked under the Arctic ice could take climate change to a whole new level. Antonio Delgado Huertas

Methane hydrates: a volatile time bomb in the Arctic

The risk with climate change is not with the direct effect of humans on the greenhouse capacity of Earth’s atmosphere. The major risk is that the relatively modest human perturbation will unleash much…
