We cannot say for sure what kind of a home Earth will offer in 2080, but averages made across thousands of model runs help paint a picture of what a 2 degrees Celsius warmer world would look like.
A mother’s willingness to sacrifice her own health and safety for the sake of her children is a common narrative across cultures — and by no means unique to humans alone. Female polar bears starve, dolphin mothers stop sleeping and some spider moms give themselves as lunch for their crawly babies’ first meal. Now an…

Scientists at the Salk Institute for Biological Studies showed that two cellular switches found on the nucleus of mouse cells, known…
The World Bank is urging stepped-up efforts to meet world carbon reduction goals after looking at what it says would be the catastrophic consequences if average world temperatures rise more than 4 degrees Celsius (7.2 degrees Fahrenheit) by the end of the century.

Researchers have observed in an experiment the exact steps bacterial genes take to evolve a new ability, unexpectedly adding a new twist on an old model
