  • How drones and AI are changing the way we fight wildfires

    The U.S. Forest Service's drone program has rapidly scaled from 734 flights in 2019 to over 17,000 in 2024, enabling safer and more efficient wildfire management by replacing dangerous pilot reconnaissance missions with unmanned thermal imaging that can detect hotspots and guide ground crews more precisely.

  • The 'frying pan of Spain' shows how cities can deal with extreme heat

    Seville has implemented three innovative water-based cooling solutions—ancient Persian qanat technology, adiabatic cooling systems in 450+ schools, and urban evapotranspiration projects—that collectively reduce temperatures by 6-12°C in public spaces and buildings while using minimal energy and attracting international attention as replicable models for heat adaptation.

  • Alaskans work to analyze and reduce risks of glacial outburst flooding

    In response to recurring glacial flooding outbursts, Juneau has implemented an early warning dashboard, $8 million temporary flood barriers, and ongoing scientific research. The solutions are too new to demonstrate measurable flood damage reduction, but increased community participation in preparedness activities is one promising impact.

  • Can rainwater-fed ponds revive Bangladesh's hilly streams?

    In Bangladesh's Chittagong Hill Tracts, conservationist Mahfuz Ahmed Russel is reviving dying streams by building artificial ponds that harvest rainwater to use in streambeds during dry seasons. Over seven years, aquatic life and vegetation have begun to repopulate and streambeds have remained wet throughout the dry season.

  • The Aromatic Roots Indians Turn to for Cooling Relief

    Khus (vetiver grass) curtains are a traditional, climate-friendly cooling method in India that is seeing a revival as extreme temperatures rise. Locals hang woven curtains made from dried vetiver roots in doorways or windows and spray them with water throughout the day. As hot air passes through them, evaporative cooling reduces indoor temperatures. This low-cost, low-energy solution has been implemented in homes and public areas like bus stops to combat the heat.

  • New App Alerts Users to Rising Rivers and Streams

    RiverAware, an app that uses real-time data from a national network of gauges, has helped citizens, first responders, floodplain managers, scientists, and recreational users such as paddlers and anglers access river-flow data, informing or alerting communities as to when it's time to evacuate or seek higher ground. The data is aggregated from more than 13,000 stream-gauging stations around the country maintained by the U.S. Geological Survey, the U.S. Army Corps of Engineers, the Bureau of Reclamation, the Bureau of Land Management and the National Weather Service.

  • Can Maine's heat pump and workforce development boom last?

    Throughout the state, Maine launched several workforce development programs to meet clean energy goals by training workers to help install heat pumps and perform other clean energy jobs. For example, Kennebec Valley Community College's heat pump lab has trained more than 300 students since 2021.

  • Long-term efforts to clean air in Alaska's second-largest city are paying off

    The Fairbanks North Star Borough implemented a comprehensive strategy to combat winter air pollution from wood-burning stoves, including: a stove replacement program that swapped over 4,000 inefficient stoves for more modern, clean-burning models, promoting kiln-dried wood with lower moisture content that burns better and adopting low-sulfur fuel requirements. The efforts have cut particulate levels in half and sulfur dioxide in the atmosphere has been reduced by 50%.

  • How Pakistan pulled off one of the fastest solar revolutions in the world

    Faced with severe heat waves, escalating electricity costs and frequent blackouts, Pakistan took a grassroots approach to transitioning to solar power, making electricity more accessible and affordable. They’ve become a major market for solar, importing 17 gigawatts of solar panels from China in 2024 alone, doubling their 2023 numbers, making Pakistan the world’s third-biggest importer of solar panels.

  • Global warming is melting Arctic ice. Can science refreeze it?

    Researchers from Real Ice, a United Kingdom-based climate-focused nonprofit, are piloting an ice-sheet conservation project that pumps ocean water to freeze on top of preexisting sea ice, aiming to reverse glacial melt.
