1. Climate

    Tropical cyclones have slowed over the last 70 years

    Tropical cyclones are moving 10 percent slower, on average, than they did in the mid-20th century, potentially making them more dangerous.

  2. Paleontology

    The Chicxulub asteroid impact might have set off 100,000 years of global warming

    About 66 million years ago, the Chicxulub asteroid impact set off 100,000 years of global warming, an analysis of oxygen in fish fossils suggests.

  3. Climate

    Bull sharks and bottlenose dolphins are moving north as the ocean warms

    Rising temperatures are making ocean waters farther north more hospitable for a variety of marine species.

  4. Animals

    ‘The Curious Life of Krill’ is an ode to an underappreciated crustacean

    A new book makes the case that Antarctic krill and the dangers they face deserve your attention.

  5. Oceans

    Masses of shrimp and krill may play a huge role in mixing oceans

    Hoards of migrating shrimp and krill can cause large-scale turbulence in the ocean, a new study suggests.

  6. Climate

    Cargo ships must cut their emissions in half by 2050

    A new international agreement places a cap on greenhouse gas emissions from international cargo ships.

  7. Oceans

    Ocean heat waves are becoming more common and lasting longer

    Over the last 100 years, the world’s oceans have sweltered through a rising number of heat waves.

  8. Environment

    Microplastics may enter freshwater and soil via compost

    Compost is pinpointed as a source of plastic pollution, but environmental fate and effects unknown.

  9. Climate

    Seafloor map shows why Greenland’s glaciers melt at different rates

    A new high-res look at the seafloor shows how ledges and dips affects whether relatively warm ocean water reaches the ice.

  10. Animals

    Humpback whale bumps have marine biologists stumped

    Christine Gabriele is taking tissue samples from humpback whales in Hawaii to determine why more and more have nodular dermatitis.

  11. Environment

    The great Pacific garbage patch may be 16 times as massive as we thought

    The giant garbage patch between Hawaii and California weighs at least 79,000 tons, a new estimate suggests.

  12. Ecosystems

    Pollution regulations help Chesapeake Bay seagrass rebound

    Regulations that have reduced nitrogen runoff into the Chesapeake Bay are driving the recovery of underwater vegetation.
