Satellites in space

Increasingly crowded orbits full of satellites and debris pose potential hazards for services on Earth, and need regulation. 

Deep-Sea Mining Guidelines Could Help us Figure Out Space Debris Regulation

After burning for 24 days, the deadly Palisades Fire in the Los Angeles area finally was declared 100 percent contained on Jan. 31, 2025. Two days later, an analysis found last month to be the warmest January on record globally. Scientists believe climate change had raised wildfire risks in Southern California prior to the blaze.  In the false-color satellite view above, scorched areas are depicted in tones of orange and red. (Credit: Modified Copernicus Sentinel data processed by Tom Yulsman)

It might have felt mighty chilly where you live, but the globe overall set yet another warming record despite La Niña's cooling influence.

Last Month Unexpectedly Finished as the Warmest January on Record

This false-color image, captured from an aircraft on Jan. 11, 2025,  shows areas burned by the Eaton fire in the Los Angeles area. Charred trees and buildings in developed areas appear dark brown, whereas burned wildland areas, are seen in shades of orange. The image was produced by NASA's Airborne Visible/Infrared Imaging Spectrometer-3, or AVIRIS-3. (Credit: NASA Earth Observatory)

A confluence of factors is making wildfires worse. Among them: increasingly dramatic swings between wet and dry conditions in a warming world.

Worsening Climate "Whiplash" Helps Explain Why California's Wildfires Were so Ferocious
