The Australian monsoon season (ASM) typically arrives in mid-December to mid-January each year but arrived on 7 February 2025 during the 2024-2025 season, more than five weeks later than usual. A group of researchers investigated whether the official arrival of the ASM in 2024-2025 was due to a true delay of the monsoon season or monsoon measurement criteria and variations in local weather conditions.

Deadly PM 2.5 air pollution that crosses state and national borders remains a serious global health issue. New research from the University of Notre Dame provides a tool to track responsibility and inform policy.

After maritime shipping emissions were sharply reduced following a mandated switch in fuels, University of Utah atmospheric scientists sprang into action to see how the change would affect cloud formation over North Atlantic. Review of satellite observations and weather data determined few droplets formed, yet the clouds’ ability to reflect sunlight remained surprisingly stable.

Researchers at the University of Kansas have shown the National Severe Storms Laboratory’s Warn-on-Forecast System(WoFS) has potential to help weather forecasters issue warnings to emergency managers and the general public well before tornado formation. Their study appears in the peer-reviewed journal Weather and Forecasting.

Methane eating microbes could help turn a powerful greenhouse gas into everyday products like animal feed, green plastics, and cleaner fuels, according to a new scientific review of fast moving research on these unusual bacteria. The study highlights how methane consuming communities, known as methanotrophs, are emerging as biological “gatekeepers” that can both curb climate warming emissions and convert waste gases into valuable resources.
