The water cycle that shuttles Earth’s most vital resource around in an unending, life-giving loop is in trouble. Climate change has disrupted that cycle’s delicate balance, upsetting how water ...

Climate tipping points are thresholds within Earth’s climate system beyond which change becomes self-reinforcing and, in some cases, irreversible on human timescales. Rather than unfolding gradually, ...

Over the course of hundreds of millions of years, Earth has lived through a series of climatic shifts, shaping the planet as we know it today. Past changes in CO 2 levels and temperature can help us ...

Global heating over this millennium could exceed previous estimates due to carbon cycle feedback loops. This is the conclusion of a new study by the Potsdam Institute for Climate Impact Research (PIK) ...

Our Earth is an incredibly dynamic planet, constantly shifting and evolving. Beyond the daily weather reports and yearly seasons, there are vast, slow-moving climate cycles—like hidden currents in a ...

Claims that climate change is natural are inconsistent with new oceanic temperature trends. New oceanic research provides clear evidence of a human "fingerprint" on climate change and shows that ...
