World Peatland Day: Protecting a crucial carbon sink

World Peatland Day: Protecting a crucial carbon sink - SLRPNK

> Peatlands are one of the world’s biggest carbon sinks. These naturally waterlogged boggy swamps can hold thousands of years’ worth of compressed, partially decomposed vegetation matter — despite covering just 3-4% of Earth’s land surface, they’re thought to store more carbon per area than the world’s forests combined. > > In honor of World Peatland Day on June 2 we present three recent Mongabay stories that shed light on this critical ecosystem. archived [https://web.archive.org/web/20250602045000/https://news.mongabay.com/short-article/2025/06/world-peatland-day-protecting-a-crucial-carbon-sink/] (Wayback Machine)

Experts have strong theories on the causes of the Birch glacier's collapse in Switzerland, and to what degree the disaster is linked to climate change — though these are yet to be confirmed by scientific analysis. https://www.japantimes.co.jp/environment/2025/06/02/earth-science/switzerland-birch-glacier-collapse/?utm_medium=Social&utm_source=mastodon #environment #earthscience #glaciers #flashfloods #climatechange #switzerland

There are strong theories on the causes, and to what degree it is linked to climate change — but these are yet to be confirmed by scientific analysis.

Weakened Atlantic Meridional Overturning Circulation causes the historical North Atlantic Warming Hole

Weakened Atlantic Meridional Overturning Circulation causes the historical North Atlantic Warming Hole - SLRPNK

cross-posted from: https://slrpnk.net/post/22954674 [https://slrpnk.net/post/22954674] > > Abstract > > > > Most oceans over the globe have experienced surface warming during the past century, but the subpolar Atlantic is quite otherwise. The sea surface temperature cooling trend to the south of Greenland, known as the North Atlantic Warming Hole, has raised debate over whether it is driven by the slowing of the Atlantic Meridional Overturning Circulation. Here we use observations as a benchmark and climate models as a tool to demonstrate that only models simulating a weakened historical Atlantic overturning can broadly reproduce the observed cooling and freshening in the warming hole region. This, in turn, indicates that the realistic Atlantic overturning slowed between 1900 and 2005, at a rate of −1.01 to −2.97 Sv century−1 (1 Sv = 106 m3 s−1 > ), according to a sea-surface-temperature-based fingerprint index estimate. Particularly, the Atlantic overturning slowdown causes an oceanic heat transport divergence across the subpolar North Atlantic, which, while partially offset by enhanced ocean heat uptake, results in cooling over the warming hole region. > > archived [https://web.archive.org/web/20250531133714/https://www.nature.com/articles/s43247-025-02403-0] (Wayback Machine)

Cluster scientist spotlight!

Kerry Kelly, PhD Associate Professor, Chemical Engineering, University of Utah

What advice do you have for students interested in science?

"It is never too late. I took a non-traditional path to my PhD, and I think the somewhat random skills I developed along the way helped me."

Chinese banks rise to claim top spot among largest funders of companies linked to deforestation - a trend that could further imperil the world’s most climate-critical forests, study finds - SDF Chatter

cross-posted from: https://lemmy.sdf.org/post/35625917 [https://lemmy.sdf.org/post/35625917] > While China touts climate goals and sustainability, its banks are pouring billions into commodities from the world’s rainforests, an investigation by the international NGO Global Witness has found. > > Archived [https://web.archive.org/web/20250530112211/https://globalwitness.org/en/campaigns/forests/chinese-banks-rise-to-claim-top-spot-among-largest-lenders-to-forest-risk-businesses/] > > Chinese banks became the largest creditors of “forest-risk” companies globally between 2018-2024 – excluding financial institutions based in Brazil and Indonesia – according to a new analysis by Global Witness, based on data released in September 2024 by the Forests & Finance coalition. > > The financial sectors of Brazil, Indonesia and Malaysia provide a disproportionate amount of “forest-risk” financing to commodity producers in their own countries and are excluded from this analysis, which focuses on international financial flows. When including these countries, China ranked third globally overall in 2023, the final year for which full data is available. > > The Forests & Finance database, compiled by Dutch research firm Profundo, tracks financial flows to over 300 “forest-risk” companies involved in agricultural supply chains such as beef, palm oil and soy production – industries that are major drivers of tropical deforestation. > > Key findings > > - Recent data shows that Chinese banks have become the largest creditors to “forest-risk”* companies, after major producing countries Brazil and Indonesia, with over $23 billion in financing provided from 2018 to 2024. > - Key Chinese banks, including CITIC, Industrial and Commercial Bank of China and Bank of China, are among the top creditors for “forest-risk” companies such as Royal Golden Eagle Group, which has faced repeated allegations that its supply chain has driven deforestation. > - The increasing flow of finance to “forest-risk” companies undermines China’s climate and environmental goals under the Glasgow Leaders’ Declaration and national Green Finance Guidelines. > - Meanwhile, Chinese banks rank poorly compared to their international counterparts in terms of deforestation-related policies, with four out of six major Chinese lenders scoring zero in the Forest 500 annual policy assessment.
