A new study of corals up to 200 years old suggests that the organisms are showing signs of resilience to the impacts of an increasingly acidic ocean.

For the first time, researchers have created an annual global dashboard that tracks 21st century trends in social shortfall and ecological overshoot, and reveals the extent to which wealthy countries drive most of the overshoot while poorer countries bear the brunt of deprivation.

Climate change poses a major threat to the organisms such as plankton that form the base of the marine food web. A team of scientists from MARUM – Center for Marine Environmental Sciences at the University of Bremen have used the fossil record to show that only a relatively minor amount of climatic change is needed to affect plankton communities. They have published their findings in Communications Earth & Environment.

Glacial melting in Switzerland was once again enormous in 2025. A winter with low snow depth combined with heat waves in June and August led to a loss of three per cent of the glacier volume. This is the fourth largest level of shrinkage since measurements began. Consequently, the ice mass reduced by one quarter in the last ten years. This was reported by GLAMOS, the glacier monitoring network in Switzerland, and the Swiss Commission for Cryosphere observation (SCC) of the Swiss Academy of Sciences (SCNAT).

Human-caused biodiversity loss has accelerated over the past fifty years. An opinion article published September 30^th in the open-access journal PLOS Biology by a team of renowned international authors, including Anne Larigauderie, former Executive Secretary of Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES), concludes that stopping biodiversity loss is contingent on transformative social and cultural changes across multiple scales.

Air quality in America’s largest cities has steadily improved thanks to tighter regulations. However, increased heat, wildfire smoke and other emerging global drivers of urban aerosol pollution are now combining to create a new set of challenges on the East Coast. Research from Colorado State University published in npj Climate and Atmospheric Science begins to unpack and characterize these developing relationships against the backdrop of New York City.

・First field-based evidence: Marimo face severe photoinhibition immediately after ice thaw due to low temperatures and intense light (LT-HL environment).

・Climate Change Risk: Earlier ice melt prolongs Marimo's exposure to damaging LT-HL conditions, threatening their long-term survival in Lake Akan.

・Astrobiological Significance: Marimo's resilience in extreme conditions offers insights into potential life strategies on icy extraterrestrial bodies and how life adapts to planetary environmental changes.
