  1. landfill

    California landfills are belching high levels of climate-warming methane

    Airborne remote sensing spots the Golden State’s biggest emitters of the potent greenhouse gas from the sky.

  2. Monsoon season in China

    Geology, not CO2, controlled monsoon intensity in Asia’s ancient past

    For millions of years, shifting geologic plates — not carbon dioxide levels —held the most sway over the intensity of Asia’s seasonal winds and rains.

  3. Earth

    Powerful storms may be causing offshore ‘stormquakes’

    A perfect-storm mixture of hurricane, ocean and seafloor topography can create distinct seismic signals called “stormquakes.”

  4. Diplodocus dino head

    Big dinosaurs kept cool thanks to blood vessel clusters in their heads

    Giant dinosaurs evolved several strategies for cooling their blood and avoiding heatstroke.

  5. Mumbai aerial

    In a climate crisis, is geoengineering worth the risks?

    Some scientists say the world needs to reconsider some human-made ideas to cool the climate as dire warnings about the looming crisis ramp up.

  6. Malin Pinsky

    Malin Pinsky seeks to explain how climate change alters ocean life

    As global temperatures rise, Malin Pinsky’s research attempts to understand how marine ecosystems are changing and why.

  7. Climate strike

    IPCC report warns of a bleak future for oceans and frozen regions under climate change

    A new IPCC report offers dire warnings about how climate change is altering oceans, the polar regions and the high snowy mountains.

  8. ice core drilling

    Expanding ice slabs are increasing Greenland’s contribution to sea level rise

    Since 2001, melting and refreezing have created vast ice layers near the surface that could drastically amp up meltwater runoff and sea level rise.

  9. Hawaii's Big Island

    How Kilauea’s lava fed a massive phytoplankton bloom

    Kilauea’s heavy flow of lava into the ocean in 2018 added both food and heat to fuel a sudden bloom of ocean algae.

  10. Hurricane Dorian radar image

    Hurricane Dorian’s slow pace makes it dangerous and hard to predict

    Hurricane Dorian is one of several recent hurricanes that moved extremely slowly. Whether that's due to climate change isn't yet clear.

  11. diatom

    Ocean acidification could weaken diatoms’ glass houses

    Ocean acidification may lead to smaller, lighter diatoms in seawater, which could also shrink how much carbon the tiny ocean algae can help sequester.

  12. cod fisherman

    Mercury levels in fish are rising despite reduced emissions

    Climate change and overfishing can increase how much mercury accumulates in fish, counteracting efforts to reduce human-caused emissions.
