Ozone pollution caused by Amazon wildfires is significantly reducing the rainforest's ability to absorb carbon dioxide from the atmosphere, new research reveals. Ground-level ozone is formed when pollutants from sources such as wildfires react in the presence of sunlight. This harms human health and interferes with…
Scientists have produced a first-of-its-kind assessment showing which coastal regions of Europe they believe are at greatest risk from harmful light pollution.
Fine particulate matter (PM2.5) is commonly associated with both health concerns and poor visibility. However, these two effects do not necessarily improve or worsen at the same time.
"Is there enough water? What's happening with climate change? How do I operate my hydro plant? In a world of water problems, there are problems that we need a good model to solve," says Colin Gleason, a hydrologist in the Riccio College of Engineering at the University of Massachusetts Amherst. But the models are only…
A flash flood can devastate a community for years in a matter of minutes. These disasters account for roughly 85% of floods and cause thousands of deaths annually worldwide, with water levels capable of shooting up 30 feet (9 meters) and receding to normal levels in the span of a single, unpredictable day, according…
In January 2013, Lake Michigan reached its lowest water level on record. Seven years later, in the summer of 2020, it broke the opposite record with widespread flooding, eroded shorelines and closed lakeside roads.
El Niño and warming in the tropical Atlantic could help provide advance warning of extreme heat in the Amazon, with some signals appearing as much as seven months earlier, new research has found. Researchers from the ARC Center of Excellence for the Weather of the 21st Century and the National Institute of Space…
This summer broke records around the U.K. for maximum temperatures and dry weather. According to the U.K.'s Met Office, while it was rare to hit 35°C (95°F) in the 20th century, that temperature has been surpassed in six out of the past 10 years. And temperatures are only expected to get higher.
The weather over the North Atlantic affects hundreds of millions of people. From winter storms over Europe to cold spells in eastern North America, many of these impacts are shaped by large-scale atmospheric circulation patterns that recur. Climate scientists refer to these preferred patterns as atmospheric regimes.
In the humid tropics of Southeast Asia, afternoon thunderstorms roll through almost every day. Daytime heat causes towering, fluffy cumulonimbus clouds to form and swell before unleashing torrential rain on cities such as Singapore, Hong Kong and Bangkok. In these places, drainage systems are designed to cope with…
A new global review of observed climate change impacts on plant communities reveals major gaps in where and how we monitor some of the world's most climate-vulnerable ecosystems.
Isaac Larsen, an associate professor in the College of Natural Sciences' Department of Earth, Geographic, and Climate Sciences, is a lead author of "Status of the World's Soil Resources 2026," a new report produced by the Food and Agriculture Organization of the United Nations (FAO) that draws on recent scientific…
