Marine heatwaves, episodes of abnormally high ocean temperatures, are increasingly affecting marine ecosystems globally. From die-back of key species to migration of entire populations, these extreme events pose urgent challenges for biodiversity, fisheries, and coastal communities.
Wildfire smoke and pollution indexes show again that public health, urban planning and climate action have become central variables in organizing major sporting events.
UCLA’s STOP Methane report identified the Norte III Environmental Complex, operated by CEAMSE, as the municipal waste site with the highest observed hourly methane rate in 2025. The finding reopens the debate on landfilling, biogas and circular economy in the Buenos Aires metropolitan area.
The Seaweed-Based Products for Decarbonization tool identifies opportunities, limits and priorities for scaling seaweed-based products in agriculture, biomaterials, critical minerals, food, animal feed and biofuels.
MCi Carbon’s Myrtle plant captures carbon dioxide from an Orica industrial facility in Newcastle and mineralizes it to produce carbonates and silica for use in concrete, paint, glass, plastics and coatings. Its initial scale is limited, but it opens an important discussion on industrial decarbonization and the circular economy.
The European Commission proposed changes to the Emissions Trading System, the bloc’s main climate tool, with a more gradual reduction path after 2030 and stronger support for industrial decarbonization. The debate shows that the energy transition also depends on rules, financing, competitiveness and institutional trust.
Recent satellite images and scientific studies indicate that the Perito Moreno Glacier has moved beyond its historic stability and entered a phase of accelerated retreat. The signal calls for stronger cryosphere monitoring, freshwater management and climate planning in southern Patagonia.
Preliminary assessments of the June heatwave recorded at least 12,000 additional deaths in Europe and a sharp rise in excess mortality during the most critical week. The episode shows that warnings, health plans, urban adaptation and protection for vulnerable people must be treated as essential infrastructure.
A subpolar Atlantic region south of Greenland and Iceland is cooling while much of the planet warms. Recent studies link that signal to changes in ocean heat transport and reinforce the need to monitor the AMOC without simplified diagnoses or alarmism.
The World Meteorological Organization’s regional climate report recorded high temperatures, marine heatwaves and historically low surface pH levels in 2025. The impacts extend to ecosystems, fisheries, economies and communities, while coordination and capacity gaps still hinder risk anticipation.
