Global warming is, by definition, experienced worldwide. But a new study shows that the tropics were the first places on earth where the human effect on climate outstripped normal climate variations.

The latest science on hurricanes and climate change explained – vital information for coastal regions to prepare for the effects of more intense storms.
Sea level rise represents one of the most worrying aspects of global warming, potentially displacing millions of people along coasts, low river valleys, deltas and islands.
What happens beneath the surface before a volcano erupts? Can we predict when one will blow? And how can typhoons and melting glaciers contribute to big eruptions?
NASA’s former climate chief, James Hansen, is lead author on a paper that predicts rapidly rising seas this century, but not all climate scientists believe the study’s models are convincing.
Some atomic ratio detective work on our solar system neighbors tells us a lot about their watery pasts. That Venus and Mars are mostly dry now could be a cautionary tale for us on the Blue Planet.
Climate models have been criticised because observations could not find the predicted “hot spot” of strong warming in the troposphere. But analyses now show that the tropospheric hot spot is indeed real.
Over the past decade, warming air temperatures at Earth’s surface appear to have slowed. But that ignores the vast majority of heat going steadily into the ocean. And, a new paper shows, that makes no difference to the long-term prognosis.
A causal relationship between cyclone behaviour and anthropogenic global warming is a very real possibility. But most climate scientists hesitate to attribute any single event to global warming.
If you’re always above average, it’s probably time to redefine what’s normal. The new normal for Earth’s climate is systematically rising temperatures.
Attacks on institutions that keep records of global temperatures, such as NASA, the US National Oceanic and Atmospheric Administration, the UK Met Office, and Australia’s Bureau of Meteorology, continue…
Cities may only occupy about 2% of the world’s habitable land, but they are big drivers of global climate change. Cities are usually hotter than rural areas, and get referred to in the jargon as “urban…
Earth’s climate is changing rapidly. We know this from billions of observations, documented in thousands of journal papers and texts and summarized every few years by the United Nations’ Intergovernmental…
Many people around the world, in certain locations, have asked, “where is global warming?” This is because they have experienced very cold wintry conditions and weird weather that they do not associate…
