A new study reveals that the seasonal march of the mid-Pliocene East Asian summer monsoon was about 10 days earlier than today, providing implications for the future change from a paleoclimate perspective.

In April 2021, two tropical cyclones, Seroja and Odette, collided in the Indian Ocean northwest of Australia. Two researchers from the University of Oldenburg, Germany, have now studied how this rare phenomenon affected the ocean. According to their case study, the rendezvous caused an unusual cooling of the surface water and an abrupt change in the direction of the combined storm. Since the frequency and intensity of tropical cyclones are increasing as a result of global warming, it is possible that such encounters – and thus more extreme air-sea interactions – will become more frequent in the future, they conclude.

Snow cover in the Sierra Nevada is expected to shrink overall as the climate warms, but avalanche frequency could remain the same or even increase at high elevations. That’s bad news for bighorn sheep that live there, according to new research to be presented at AGU’s 2024 Annual Meeting.

A new study conducted by D-Hygea Lab of the Department of Electronics, Information and Bioengineering of the Politecnico di Milano, in collaboration with the Regional Emergency Agency (AREU), has analysed the impact of heat waves on the cardiovascular health of Milan residents. The results show that in 18 highly vulnerable districts, home to 23% of the city’s population, the risk of cardiovascular emergencies increases by 22% during days of extreme heat compared to normal days. In contrast, in 20 low vulnerability districts, the increased risk is not significant
