A new study published by researchers at the University of Hawai‘i at Mānoa sheds light on the critical role of iron in Earth’s climate history, revealing how its sources in the South Pacific Ocean have shifted over the past 93 million years. This groundbreaking research, based on the analysis of deep-sea sediment cores, provides crucial insights into the interplay between iron, marine life, and atmospheric carbon dioxide levels.

Tulane researchers found that mid-1990s climate projections of sea-level rise were remarkably accurate when compared with 30 years of satellite data. The 1996 IPCC report predicted about 8 cm of rise, close to the 9 cm observed, though it underestimated ice-sheet contributions. The study highlights both the credibility of climate models and the importance of continued monitoring. Researchers stress the need for region-specific projections, especially for vulnerable coastal areas like south Louisiana, where sea-level rise varies widely.

Researchers at the College of Design and Engineering at the National University of Singapore (NUS) Urban Analytics Lab have developed an open-source AI model that maps carbon emissions from individual buildings using only publicly available data. Applied to more than 500,000 buildings across five global cities (Singapore, New York, Melbourne, Seattle and Washington DC) the model accurately identifies emission hotspots and reveals how a city’s planning history, building density, and income levels shape urban carbon footprints. The tool, which uses satellite imagery, street views, and other open geospatial data, aims to help cities design more targeted and equitable climate policies.

The American Chemical Society (ACS) Fall 2025 meeting, held from August 17 to 21 in Washington, DC, has proven to be a monumental event in the scientific community. As the largest international academic event in the field of chemistry, it has drawn researchers, academics, and industry leaders from across the globe, all converging to discuss the latest advancements and challenges in chemistry and its multidisciplinary applications.

A new study from researchers at the University of North Carolina at Chapel Hill has revealed the key factors that determine where trees can grow at the highest elevations across the globe.

The Global Observing SATellite for Greenhouse gases and Water cycle “IBUKI GW” (GOSAT-GW), developed jointly by the National Institute for Environmental Studies (NIES), the Ministry of the Environment of Japan (MOE), and the Japan Aerospace Exploration Agency (JAXA), was successfully launched on June 29, 2025. The satellite has been in the initial functional verification operations phase. The first observations by the Total Anthropogenic and Natural emissions mapping SpectrOmeter-3 (TANSO-3) onboard this satellite were conducted from July 14 to July 20, 2025, and the proper operation of TANSO-3 was confirmed.
