Projections of our future under climate change paint a picture of extreme weather and acidified oceans, a world many of today’s animals — including humans — may struggle, or fail, to survive. Yet ...

Reliable predictions of how the Earth's climate will respond as atmospheric carbon dioxide levels increase are based on climate models. These models, in turn, are based on data from past geological ...
