climate models

A Washington Post climate reporter traveled to Mexico to test-drive vehicles sold there but not offered in the United States, arguing that drivers in Mexico are getting a glimpse of the future of affordable, efficient cars that remain off-limits to American buyers. The piece frames US market rules and automaker choices as reasons Americans miss out on models available just across the border.

William Nordhaus, the Yale economist who won the Nobel Prize for integrating climate change into economic analysis, has died. Nordhaus developed the DICE model linking economic growth and carbon emissions, shaping decades of climate policy debate including carbon pricing. Tributes are highlighting his decades at Yale and his pioneering role in environmental economics.

Researchers have identified a previously unknown carbon assimilation pathway in Arctic Ocean bacteria, in which the microbes use acetone to fix carbon. The finding expands understanding of how carbon cycles through polar marine ecosystems and suggests microbial life in cold oceans may process volatile organic compounds in ways not captured by existing climate and carbon-cycle models.

A new explorable piece examines how mathematics and physics have been used to predict catastrophic scenarios, from asteroid impacts to climate tipping points and existential risks. It walks through the models scientists rely on when estimating how the world could end, and how accurate those predictions have proven. Readers are weighing how seriously such doomsday forecasting should be taken.

The Global Business Initiative, working with the Business and Human Rights Resource Centre, has published a briefing exploring how corporate boards can advance a just transition to a low-carbon economy. The briefing focuses on board oversight, accountability and decision-making as companies shift business models while protecting workers and communities affected by the transition.

William Nordhaus, the American economist who won the Nobel Prize in Economic Sciences for his work on the economics of climate change, has died at the age of 85. Nordhaus pioneered modeling of carbon taxes and the costs of global warming, shaping climate policy debates for decades, and tributes are highlighting his lasting influence on how governments price carbon.

The Jülich Supercomputing Centre in Germany is hosting EVE, a language model built for Earth observation and Earth science research. The model will support analysis of satellite data and geoscientific workloads, running on Jülich's high-performance computing infrastructure. The announcement highlights the growing role of large AI models in climate and environmental research, and positions Jülich as a hub for scientific AI computing in Europe.
