China pushes clean energy targets at UN climate summit
At the UN Climate Summit, China highlighted its progress in clean energy adoption amid global efforts to combat climate change. Officials emphasized accelerated goals for renewable energy and emissions reduction. The announcements underscore China's role in international climate action.
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.
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.
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.
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.
Former Google CEO funds autonomous boats for Antarctic exploration
Eric Schmidt, the former CEO of Google, has announced funding for a project deploying autonomous boat drones to navigate the treacherous waters of Antarctica's Amundsen Sea. The initiative, in partnership with Saildrone, aims to map the seafloor and collect data on ocean currents amid climate change concerns. This effort builds on Schmidt's ongoing interest in ocean exploration.
Trump administration purges negative signs from national parks
The Trump administration has ordered the removal of interpretive signs in U.S. national parks that discuss environmental threats like climate change and pollution. This effort, led by the Interior Department, aims to eliminate messaging perceived as negative. Critics argue it suppresses scientific information on public lands.
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.
Antarctic glacier passes tipping point for sea level rise
A new study indicates that the Thwaites Glacier in Antarctica has crossed an irreversible tipping point, potentially accelerating global sea level rise. Researchers analyzed decades of satellite data to reach this conclusion. The findings highlight the urgent risks posed by climate change in polar regions.
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.
Researchers develop sunlight-powered carbon capture method
4 Mwezi wa kumi, 2025 Imeripotiwa na AI
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.
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.
