Study links wildfires and heat to worse air quality in megacities

A recent study highlights how increasingly frequent wildfires and heat events are aggravating air pollution in major urban areas. Researchers found that these climate-driven factors significantly elevate levels of harmful particulates and ozone. The findings underscore the growing environmental challenges for densely populated cities.

Absurdist theater artist readies New Yorkers for climate floods

In Brooklyn, theater artist Alexx Klein stages absurd performances to confront New York City's climate vulnerabilities. His project 'Flood Futures' simulates disaster scenarios to blend humor with urgent warnings about rising seas. Through laughter and mock evacuations, Klein aims to ease climate anxiety while educating the public.

Scalise leads GOP effort to block Colorado climate lawsuits

House Majority Leader Steve Scalise and 102 Republican lawmakers have filed an amicus brief with the Supreme Court, urging it to halt climate lawsuits against Exxon and Suncor Energy from Boulder, Colorado. The Republicans argue that such cases represent a federal matter involving global emissions, not state jurisdiction. The move comes after the Colorado Supreme Court allowed the suits to proceed in May.

Researchers develop sunlight-powered carbon capture method

Scientists have unveiled a new photocatalyst that uses sunlight to convert carbon dioxide into usable fuel, offering a promising tool for combating climate change. The breakthrough, detailed in a study published on October 3, 2025, achieves high efficiency without needing additional energy inputs.

At least 170 US hospitals face major flood risks

A recent analysis reveals that at least 170 hospitals across the United States are vulnerable to severe flooding, posing risks to healthcare infrastructure amid worsening climate conditions. Experts attribute part of the escalating threat to policy decisions under former President Donald Trump that rolled back environmental protections. This vulnerability could disrupt critical medical services for millions during disasters.

A group of young Americans who sued the federal government over climate change in 2015 continues their legal battle despite repeated court setbacks. The plaintiffs, represented by Our Children's Trust, argue that government policies violate their constitutional rights. Recent efforts focus on new strategies to revive the case.

Marine heat waves clog ocean's carbon sequestration mechanism

Two major marine heat waves in the northeastern Pacific have disrupted the ocean's natural process of sinking carbon to the seafloor via zooplankton fecal pellets. A new study reveals shifts in phytoplankton and zooplankton communities that reduced carbon export during these events. This malfunction could impair the ocean's ability to absorb a quarter of human CO2 emissions.

Plumas National Forest pursues ambitious wildfire protection plan

The U.S. Forest Service has launched the Plumas Community Protection project to safeguard 285,000 acres of Northern California's Plumas National Forest from megafires through thinning, logging, and prescribed burns. Funded by $274 million from Congress in 2023, the initiative aims to build forest resilience following the devastating 2021 Dixie Fire. However, progress has been slow amid bureaucratic challenges and limited transparency.

Scientists revive microbes dormant in permafrost for 46,000 years

Researchers have successfully awakened ancient microbes trapped in Siberian permafrost for up to 46,000 years. The experiment demonstrates the remarkable resilience of these microorganisms. The findings, published in Nature Communications, raise concerns about potential pathogen release as permafrost thaws due to climate change.

Study shows climate change intensifying Europe's largest hailstorms

A new study reveals that climate change is making Europe's biggest hailstorms more severe, with larger hailstones forming due to warmer temperatures. Researchers analyzed data from the record-breaking 2023 hailstorm in northern Italy, where hail up to 15 centimeters fell. The findings highlight how rising atmospheric moisture is fueling these extreme weather events.
