Millions of children will be affected in unprecedented ways by heat waves, crop failures, river flooding, droughts, forest fires and tropical storms during their lifetime under current climate policy measures.

A new study in the journal Nature Climate Change shows that the richest ten percent of the world's population is responsible for two-thirds of the global warming observed since 1990 and the associated extreme weather events such as heat waves and droughts.

Up to that 9.4% of Earth's terrestrial ecosystems face potential transformation by 2050 due to changes in tropical cyclone activity. In their study, Chahan M. Kropf and colleagues from ETH Zurich show the significant impact of changing tropical cyclone patterns on global ecosystems.

Pioneering study reveals that limiting global warming to 1.5?C could reduce the global economic costs of climate change by two thirds. If warming continues to 3?C, global GDP will decrease by up to 10 percent - with the worst impacts in less developed countries.

Antarctica harbours a large concentration of meteorites imbuing the icy continent with an unparalleled wealth of information on our Solar System. However, these precious meteorites are rapidly disappearing from the ice sheet surface due to global warming.

At the UN Climate Change Conference in Dubai 2023 (COP28), an international research team has presented the global carbon budget for 2022, with a forecast for 2023. More than 120 researchers have contributed to this year¡¯s "Global Carbon Project". Also involved are ETH climate scientists Nicolas Gruber and Luke Gregor. ?

The Swiss National Supercomputing Centre (CSCS), ETH Zurich and the European Centre for Medium-Range Weather Forecasts (ECMWF) are teaming up to develope more accurate weather and climate models that are even better adapted to the latest computer architectures.

Researchers at the Paul Scherrer Institute PSI and ETH Zurich have performed calculations to work out how air traffic could become climate-neutral by 2050. They conclude that simply replacing fossil aviation fuel with sustainable synthetic fuels will not be enough. Air traffic would also have to be reduced.
