Cooking Emissions Rival Fossil Fuels as an Ozone Pollution Source in Los Angeles

4/9/2025 - By research.noaa.gov. As the adoption of cleaner-burning engines and electric vehicles drives fossil fuel emissions lower, scientists have discovered that a surprising pollution source is playing a significant role in cooking up ozone in the air over Los Angeles. According to new research from NOAA, the potent and often pungent… SEE MORE

Celebrating 65 Years of the World’s First Weather Satellite

4/3/2025 - By nesdid.noaa.gov. On April 1, 1960, the National Aeronautics and Space Administration (NASA) launched TIROS-1, the world’s first successful meteorological satellite. Nearly 68 years ago, on October 4, 1957, the former Soviet Union launched Sputnik 1, the first artificial satellite to be successfully placed in orbit around Earth. This feat… SEE MORE

What’s the Hottest Earth’s Ever Been?

3/12/2025 - By Michon Scott and Rebecca Lindsey. Our 4.54-billion-year-old planet probably experienced its hottest temperatures in its earliest days, when it was still colliding with other rocky debris (planetesimals) careening around the solar system. The heat of these collisions would have kept Earth molten, with top-of-the-atmosphere temperatures upward of 3,600° Fahrenheit.… SEE MORE

Gray Whales on the Rebound: Signs of Hope Despite Challenges

2/24/2025 - By fisheries.noaa.gov. North Pacific gray whale population increases after declines. California's gray whales are an iconic and beloved species, visible to spectators even from shore during their migrations. The whales feed up in the Arctic and sub-Arctic waters in the North Pacific, then migrate all the way down the coast of… SEE MORE

The Bowheads of Baffin Island

2/14/2025 - By Tyee Bridge. New tools—from drones to crossbows to suction-cup cameras—are helping researchers understand bowhead whales in the Canadian Arctic. Bowhead whales are fascinating creatures—even by whale standards. Named for their arched mouths, which happen to be the largest maws of any animal⁠, these whales are now also believed to… SEE MORE

Scientists Solve the Mystery of Sea Turtles’ ‘Lost Years’

2/9/2025 - By Christina Larson. Using satellite trackers, scientists have discovered the whereabouts of young sea turtles during a key part of their lives. “We’ve had massive data gaps about the early baby to toddler life stages of sea turtles,” said Kate Mansfield, a marine scientist at the University of Central Florida. “This part… SEE MORE

Arctic Tundra Becoming Source of Carbon Dioxide Emissions

1/31/2025 - By noaa.gov. 2024 Arctic Report Card tracks rapid, complex Arctic change. After storing carbon dioxide in frozen soil for millennia, the Arctic tundra is being transformed by frequent wildfires into an overall source of carbon to the atmosphere, which is already absorbing record levels of heat-trapping fossil fuel pollution. The… SEE MORE
