The Alaskan Permafrost Is Thawing. Here’s Why That’s so Worrying
A new study shows that a Wisconsin‑sized area of Alaskan permafrost now releases about 12 cubic kilometers (three trillion gallons) of fresh water each year, a volume exceeding the total output recorded in the early 1980s. Between 1980 and 2023, dissolved organic carbon discharged by northern Alaska’s rivers grew from roughly 120 to 170 gigagrams, adding about 50,000 metric tons of carbon annually to the ocean. The influx of freshwater disrupts sea‑ice formation, alters coastal salinity, and could destabilize global ocean circulation. Researchers say the findings sharpen our ability to quantify permafrost‑driven carbon emissions, a critical feedback in a region warming three times faster than the globe.
Inside a Bold Plan to Pulverize an Earth-Bound Asteroid
Researchers at UC Santa Barbara propose "Pulverize It," a planetary‑defense concept that would shatter hazardous asteroids using Falcon 9‑launched penetrators, ranging from tungsten rods to nuclear explosives.
