WEB4 days ago — This is three times higher than the amount secured last year. It is also a new capacity record, if wind power projects from 2022 that were subsequently cancelled or scaled back are excluded, according to the analysis. Carbon Brief covers climate science, energy and policy, specialising in clear, data-driven articles to improve the understanding ...
Factcheck: How electric vehicles help to tackle climate change
WEBMay 13, 2019 — Other recent studies of electric cars in Germany have reached the opposite conclusion. One study found that emissions from EVs have emissions up to 43% lower than diesel vehicles. Another detailed that “in all cases examined, electric cars have lower lifetime climate impacts than those with internal combustion engines”.

WEBDec 13, 2017 — The extent of the human contribution to modern global warming is a hotly debated topic in political circles, particularly in the US. During a recent congressional hearing, Rick Perry, the US energy secretary, remarked that “to stand up and say that 100% of global warming is because of human activity, I think on its face, is just indefensible”. ...
Explainer: The high-emissions ‘RCP8.5’ global warming scenario
WEBAug 21, 2019 — A sizeable portion of recent studies on future climate impacts have focused on a warming scenario called “RCP8.5”. This high-emissions scenario is frequently referred to as “business as usual”, suggesting that is a likely outcome if society does not make concerted efforts to cut greenhouse gas emissions. In recent years the emissions ...
