    Extreme ocean heat off Florida has ebbed. But for marine life, the danger remains

    After the recent heat wave, corals have received too much heat too early in the summer, and other sea life could see lingering effects too.

    Irrigation may be shifting Earth’s rotational axis

    Computer simulations suggest that from 1993 to 2010 irrigation alone could have nudged the North Pole by about 78 centimeters.

    Satellite data reveal nearly 20,000 previously unknown deep-sea mountains

    By looking for tiny bumps in sea level caused by the gravity of subsurface mountains, researchers have roughly doubled the number of known seamounts.

    50 years ago, researchers discovered a leak in Earth’s oceans

    An analysis of oceanic rocks hinted that ocean water drains into Earth’s mantle. How much makes it back into the ocean remains unclear.

    50 years ago, scientists discovered the Great Pacific Garbage Patch

    In 1973, plastic bottles adrift in the North Pacific alarmed scientists. Fifty years later, more than 1.8 trillion pieces of plastic litter the area.

    Rapid melting is eroding vulnerable cracks in Thwaites Glacier’s underbelly

    Thwaites is melting slower than thought, but the worst of it is concentrated in underbelly cracks, threatening the Antarctica glacier’s stability.
