The downward trend in snowfall across the entire alpine range between 1920 and 2020 is notable, with an overall 34% decrease. These are the results of a study coordinated by Eurac Research and published in the scientific journal International Journal of Climatology on December 4. The analysis also took into account how altitude and climatological parameters such as temperature and total precipitation affect the picture. Seasonal data on snowfall and rainfall came from 46 locations scattered throughout the Alps.

You may have noticed that every year the leaves turn yellow and fall later and later. You didn't: a review of 64 studies from 1931 to 2010 in Asia, Europe and North America confirmed that rising global temperatures have delayed leaf fall in the Northern Hemisphere. Michael Lavelle, a senior lecturer in the Department of Landscape Management at Anglia Ruskin University, examined the causes and consequences of this trend in the pages of The Conversation.

People in the world's smallest countries, those that contribute the least to climate change, are the hardest hit, especially by flooding. And the situation is getting worse. These are the results of a study conducted by the University of Bristol and published Nov. 10 in the journal Environmental Research Letters. The research found that, on average, nearly one in five people among the inhabitants of small island developing states - about 8.5 million people in total - are currently affected by coastal and inland flooding. Three of these 57 countries, concentrated in the Pacific, Caribbean, Indian Ocean and South China Sea, namely the Bahamas, Guyana and Tuvalu, tripled that percentage to more than 60 percent of the population, according to the findings.

This year Azerbaijan is hosting the 29th session of the Conference of the Parties to the UN Framework Convention on Climate Change (COP-29). This is the largest international event in the country's history. About 80,000 foreign guests will arrive at COP29, which will be held from November 11 to 22 at the Baku Stadium, and more than 50 heads of state and government have confirmed their participation in this large-scale event. The main expectation from COP29 is to agree a fair and ambitious New Collective Quantitative Goal (NCQG) for climate finance.

The Mediterranean Sea temperature record since the beginning of modern observations was set in 2023, with the average surface temperature increasing by more than 1 degree Celsius in 25 years, there has been a gradual increase in temperature since 2013 in the southern Tyrrhenian Sea, spreading northwards, and warming of deeper layers, up to 800 meters. This is the conclusion reached by ENEA and INGV within the MACMAP project in collaboration with GNV, the ferry company of the MSC Group. This was reported on November 8 by the Italian publication AGI.

Swedish activist Greta Thunberg attended a rally in support of climate change and Palestinians in Milan on Friday. More than 1,000 people, many of them teenagers, joined a peaceful march in this northern Italian city organized by Fridays For Future, a climate change movement that Thunberg helped found. Wearing a kufiya - a traditional scarf symbolizing the Palestinian struggle against Israel - Thunberg walked at the front of the procession, while other protesters waved flags, held banners and danced to music.

Massive rainfall inundated parts of Central and Eastern Europe in mid-September, dumping as much as two-thirds of some cities’ annual rain in just a few days. The rainfall from the weather system, called Storm Boris, drove floods that claimed 24 lives. But early warnings from weather forecasters gave many cities time to prepare, and infrastructure improvements in others helped protect residents from the deluges, says Maja Vahlberg, a climate risk consultant with the Red Cross Red Crescent Climate Centre. It’s a sign, she says, that some parts of Europe, at least, are beginning to adapt to the more extreme weather brought on by human-caused climate change.
