European institutions launch campaign for International Coccolithophore Day

Five European research institutions have announced an initiative to establish October 10 as International Coccolithophore Day, highlighting the crucial role of these microscopic plankton in regulating Earth's climate. Coccolithophores, tiny algae smaller than dust grains, capture carbon dioxide, produce oxygen, and form geological records of climate history. The campaign aims to raise awareness of their impact on ocean ecosystems amid climate change threats.

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.

Study links extreme heat to workplace injuries as OSHA faces delays

A new study reveals that extreme heat contributes to thousands of workplace injuries annually, with risks rising above 85 degrees Fahrenheit heat index. Researchers confirm that basic protections like water, shade, and breaks reduce these risks. However, a federal government shutdown threatens to delay OSHA's proposed national heat standard.

Youth climate plaintiffs persist in lawsuit against US government

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.

Plumas National Forest pursues ambitious wildfire protection plan

8. Oktober 2025 Von KI berichtet

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 develop nanotechnology for efficient carbon capture

Researchers have unveiled a new nanotechnology-based method that captures carbon dioxide at 90% efficiency in lab tests. This innovation could significantly aid global efforts to combat climate change. The findings were published in Nature on October 3, 2025.

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.

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.

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.

Opinion piece urges rethinking urban design for climate resilience

Dr. Rob Moir argues in a guest opinion that climate change intensifies storms and flooding through warmer air and impervious urban surfaces. He calls for reconnecting with natural land and water cycles to build resilient cities. Solutions like permeable pavements and rain gardens could mitigate risks.

Scalise leads GOP effort to block Colorado climate lawsuits

11. Oktober 2025 Von KI berichtet

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.
