Both Chen et al. (Science, 01.2025) and Gebrechorkos et al. (Nature, 06.2025) report similar trends, e.g. that droughts are intensifying globally, driven by warming, and affecting larger areas.

Bert Wuyts is sharing our latest work on modeling #tipping-points in mountain ecosystems ⛰️ at the #TipESM annual meeting. Do #mountain #ecosystems hit critical tipping points in a warming world — and if so, when? 🌍⚠️ A great chance to exchange ideas. @tipesm.bsky.social ial @wsl-dme.bsky.social

#CHELSA has now entered its 15th year of development, and yesterday, I had the pleasure of presenting it at the #MeteoSwiss 🇨🇭, Switzerland’s national weather service. I really appreciated the insightful discussions and the open exchange on current and future challanges. @wsl-dme.bsky.social

6/ Why does this matter?

💧 Water shortages could impact drinking water, agriculture & hydropower
🌲 Forests weakened by drought are more vulnerable to wildfires & disease
⛰️ The Alps are already under significant climate stress—rising drought frequency will make this worse.

David L. Hoover and William K. Smith also published an amazing overview in @science.org on how our study fits into the recent research on this topic and that "... a deeper understanding of multiyear droughts is still lacking." www.science.org/doi/10.1126/... @wsl-dme.bsky.social

All our data is freely available for public use: Climate data: chelsa-climate.org. Drought data: envidat.ch With open access we hope to better support understanding and action of these events. 🌎(7/7) envidat.ch#/metadata/gl...,

For example, in Pacific Palisades, Los Angeles, almost no wet years have been recorded since 2000. Droughts in this region as shown in the graph with red = drier years, and blue = wetter years have contributed to the devastating wildfires in recent days (6/7)

Droughts also drive other disasters, like wildfires. In the U.S. West, prolonged droughts since 1980 have made vegetation more flammable, fueling widespread wildfires amd water shortages. The image shows all the multi-year droughts from 1980-2018 that happend in this region (5/7)

Chile offers a stark example: a 14-year mega-drought has devastated local agriculture and water supplies. Entire regions have been abandoned. The pictures show the region around Los Andes, where dead vineyards in the Aconcagua basin highlight these severe effects (4/7)

Not only is the area affected by droughts increasing, but their impact on global ecosystems is intensifying. Satellite data show plants drying out more severely, a trend observable even from space. (3/7)
January 17, 2025 at 1:35 PM
Extreme droughts are rising worldwide due to the instability of a warmer atmosphere. This leads to more climate extremes like droughts, extreme rainfall, heatwaves, and storms. Each year, the area affected by droughts grows by the size of Switzerland. (2/7)

🌍 Mega-droughts are becoming more frequent and intense globally. Our study in Science www.science.org/doi/10.1126/... shows that multi-year droughts have significantly increased over the last 40 years with severe impacts @wslresearch.bsky.social @wsl-dme.bsky.social @extremeswsl.bsky.social (1/7) 🧵

🌍 Exciting day at #SeoulNationalUniversity! 🇰🇷 Dr. HyeJin Kim and I shared our vision for Korea's #NatureFutures, exploring how land use, economic development, #biodiversity, & #ClimateAction can shape a sustainable future. @wslresearch.bsky.social

Had an excellent exchange with the National Assembly Futures Institute (NAFI), the think tank of South Korea’s National Assembly. Together, we aim to build resilient, sustainable future scenarios for Korea.

🌏 Honored to participate in the DMZ Open ECOPEACE FORUM in Goyang, South Korea , where we explored how ecology can play a vital role in fostering peace on the Korean Peninsula.

With #COP28 for the first time agreeing that the days of fossil fuels are numbered, lets all make sure its not all empty promises. Sequestering 50% of emissions for free, protecting nature and #biodiversity is essential to fight #climatechange.

Starting to explore the Green Zone of #COP28 before our session tomorrow on #Biodiversity and #ClimateChange mitigation tomorrow
