Research attempts to quantify the value of U.S. property at risk in forested areas exposed to increased ecological disturbance associated with climate change, such as wildfire and tree mortality. Property exposed to such climate risks, especially in California, is project to climb substantially if emission-reduction measures are not taken.

Over recent decades, there was a large variation in cyclone-related excess deaths by hurricane, state, county, year, and social vulnerability for counties in the United States, with 83 percent of hurricane-related deaths occurring more recently and 94 percent in more socially vulnerable counties.

Medications to treat various chronic diseases may hinder the body's ability to lose heat and regulate its core temperature to optimal levels. The loss of effective thermoregulation has implications for elderly people receiving treatment for illnesses like cancer, cardiovascular, Parkinson's disease/dementia and diabetes, particularly during hot weather, according to a review by a team of scientists.

Birds likely hold smart insights about coexisting in popular habitats -- especially as climate change looms. Scientists peel back layers of big data to tease out real-life answers.

A new study finds that ongoing extreme heat can worsen cognitive decline among vulnerable groups -- particularly Black older adults and those living in poor neighborhoods.

With climate change, irrigating more crops in the United States will be critical to sustaining future yields, as drought conditions are likely to increase due to warmer temperatures and shifting precipitation patterns. Yet less than 20% of croplands are equipped for irrigation. A new study finds that by the middle of the 21st century under a moderate greenhouse gas emissions scenario, the benefits of expanded irrigation will outweigh the costs of installation and operation over an expanded portion of current U.S. croplands. The study maps where it makes the most sense to install irrigation for corn and soybeans and if there's enough water to do so.

Investment in 'hydromet systems' using technologies from AI to SMS would provide a nine-to-one ROI in saved lives and assets across African nations.

Dry lightning can still be disastrous even when conditions aren't so dry, a study has found. These cloud-to-ground strikes during little to no rainfall were previously thought to pose wildfire danger only if occurring with less than 2.5 mm of rain in a day (about 0.10 inches). A new study of lightning-ignited wildfires in the U.S. West found the strikes caused wildfires despite up to 7.7 mm (about 0.3 inches) of precipitation. While still a low amount of rain, the more accurate estimation could help responders detect fires earlier, especially those known as 'holdovers,' which can smolder for many days before exploding into full-blown wildfires.

While some parts of the world suffer extreme heat and persistent drought, others are being flooded. Overall, continental water volumes vary so much over time that global sea levels fluctuate significantly too. By combining the hydrological model WaterGAP with GRACE satellite data, a team of geodesists have come up with a new set of data that shows how the total distribution of water over the Earth's land surfaces has changed over the past 20 years more accurately than ever before.

If climate models predict that much of tropical Africa will become wetter with a warming climate, then why does it keep getting drier in the Horn of Africa?

A telecommunications fiber optic cable deployed offshore of Oliktok Point, Alaska recorded ambient seismic noise that can be used to finely track the formation and retreat of sea ice in the area, researchers report.

Scientists have identified large-scale climate patterns that could be used to predict the co-occurrence of extreme heat and ozone days in China months before they occur. Like predictions for hurricane and wildfire seasons, the forecasts could help the government prepare resources and implement policies to mitigate the severity of the season.

In-water monitoring shows hard coral cover across the Great Barrier Reef remains at similar levels to that recorded in 2022, with small decreases in the Northern, Central and Southern regions. AIMS' Annual Summary Report on Coral Reef Condition for 2022/23 found that while some reefs continued to recover, their increased hard coral cover was offset by coral loss on other reefs. Most reefs underwent little change in coral cover.

City life favors species that are adaptable and not too fussy about what they eat, among other characteristics. A worldwide consortium of scientists calls the resulting collection of traits an 'Urban Trait Syndrome.'

Extreme events in Antarctica such as ocean heatwaves and ice loss will almost certainly become more common and more severe, researchers say.

A new study analyzing toxins produced by Microcystis, the main type of cyanobacteria that compose the annual harmful algal bloom (HAB) in Lake Erie, suggests that the toxicity of the bloom may be overestimated in earlier warm months and underestimated later in the summer.

Ecologists examined the distribution patterns of canopy soils, and their soil properties, across Costa Rican forests. The researchers suggest canopy soil may store more carbon than previously thought. Consideration of the time needed for reforestation of system with tree canopies should include the time needed for canopy mat regrowth.
