    2018 was the fourth-hottest year on record, and it’s getting even hotter

    Overall, 2018 was the fourth-warmest year on record, and climate change trends suggest that temperatures will only continue to climb, scientists said February 6 during a joint news conference by the National Oceanic and Atmospheric Administration and NASA.

    The agencies’ data show that global atmospheric temperatures in 2018 were on average 0.79 degrees Celsius warmer than the average...

    Five explosive things the 2018 eruption taught us about Kilauea

    After a stunningly volatile 2018, Hawaii’s Kilauea volcano, which had been continuously erupting since 1983, finally seems to be taking a break. Following 35 years of nonstop activity, no lava is currently flowing from the Big Island’s most famous volcano.

    Scientists thought they knew Kilauea pretty well. It’s one of the most closely monitored volcanoes in the world, with instruments...

    Earth’s core may have hardened just in time to save its magnetic field

    Earth’s inner core solidified sometime after 565 million years ago — just in time to not only save the planet’s protective magnetic field from imminent collapse, but also to kick-start it into its current, powerful phase, a new study suggests.

    The finding, reported online January 28 in Nature Geoscience, supports an idea previously proposed by simulations that Earth’s inner core is...

  • 50 years ago, scientists tried to control earthquakes with earthquakes

    The Federal Council for Science and Technology … recommends a 10-year national earthquake research program to find ways to predict when and where quakes will strike and … [how to] defuse and prevent earthquakes, or at least modify them. Basically, the idea is simple: Inject fluid into underground rock, release the strain and produce a gradual series of tiny earthquakes or tremors...

    Erosion has erased most of Earth’s impact craters. Here are the survivors

    When it comes to impact craters, Earth is the pauper of the solar system.

    Even with a recent, still-to-be-confirmed crater discovery under Greenland’s ice, there are fewer than 200 known impact craters on the planet. Mars, for comparison, has hundreds of thousands.

    Produced by falling space rocks, most impact craters on Earth have been wiped away over time by wind, rain, shifting...
