Carbon Capture
“It’s very well-documented that the oceans are a big missing piece in the social cost of carbon.”

Urban Methane Emissions Are Rising, Despite Cities’ Pledges
Eyes in the sky could help cities get on track to decrease emissions of the potent greenhouse gas—and monitor whether their efforts are working.
Fatal landslides in April 2026
In April 2026 I recorded 36 fatal landslides causing 90 fatalities, the lowest monthly total for 2026 to date. This is my regular update for the number of fatal global landslides, focusing on March 2026. As usual, this data has been collected in line with the methodology described in Froude and Petley (2018) and in Petley (2012). References…
Want to Predict Wildfire Severity? Look to the State of Vegetation
A new study connects satellite data on vegetation condition, topography, and weather conditions to examine the predicted versus actual burn severity of the 2025 Los Angeles wildfires.
Drivers of Day-to-Day Temperature Swings Across Continents
Abrupt temperature swings aren’t random—large-scale air mass shifts and seasonal processes drive day-to-day variability across major Northern Hemisphere regions.
How Wildfires Worsen Flood Risk
A new approach to analyzing watersheds shows how storms occurring after a wildfire can have higher flooding risk than similar storms that occurred before a fire.
Toward Marine Cloud Brightening at Scale: A Science Agenda
Marine Cloud Brightening (MCB) is a Solar Radiation Management (SRM) solution to cool the planet by changing the albedo of low-altitude marine clouds to increase reflected shortwave radiation.
Antibiotic Resistance Might Get a Boost from Droughts
Drought has the potential to turn normal soils into perfect breeding grounds for antibiotic-resistant bacteria, new research has found.
Temperatures in Nearly All Major U.S. Cities Have Warmed Since First Earth Day
After more than half a century of Earth Days, one planetary challenge—climate change—threatens our planet more than ever.
In 1970, the year Sen. Gaylord Nelson, D-Wisc., organized the first Earth Day events, the annual average concentration of carbon dioxide in the atmosphere was 326 parts per million. In 2025, it was 31% higher, at 427…
Location, Location, Location: The “Where” of Reforestation May Matter More Than the Extent
A new study finds that focusing reforestation efforts in strategic locations, such as the tropics, can accomplish global cooling levels comparable to less strategic reforestation efforts covering twice as much area.
Weather Radar Data Reveal the Dynamics of Rapidly Spreading Wildfires
New research demonstrates the use of operational weather radar measurements to track long-range ember fallout and rapid spread of intense wildfires.
