  • NASA Study Identifies New Pathway for Greenland Meltwater to Reach Ocean

    Cracks in the Greenland Ice Sheet let one of its aquifers drain to the ocean, new NASA research finds. The aquifers, discovered only recently, are unusual in that they trap large amounts of liquid water within the ice sheet. Until now, scientists did not know what happened to the water stored away in this reservoir -- the discovery will help fine tune computer models of Greenland’s contribution to sea level rise.

  • Researchers Catch Extreme Waves with High-Resolution Modeling

    Surfers aren’t the only people trying to catch big waves. Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) are trying to do so, too, at least in wave climate forecasts.

  • 'The blob' of abnormal conditions boosted Western U.S. ozone levels

    An unusually warm patch of seawater off the West Coast in late 2014 and 2015, nicknamed “the blob,” had cascading effects up and down the coast. Its sphere of influence was centered on the marine environment but extended to weather on land.

  • Canadian glaciers now major contributor to sea level change, UCI study shows

    Ice loss from Canada’s Arctic glaciers has transformed them into a major contributor to sea level change, new research by University of California, Irvine glaciologists has found.

    From 2005 to 2015, surface melt off ice caps and glaciers of the Queen Elizabeth Islands grew by an astonishing 900 percent, from an average of three gigatons to 30 gigatons per year, according to results published today in the journal Environmental Research Letters.

  • NASA Eyes the Heart of Tropical Cyclone Dineo on Valentine's Day

    On Feb. 14, 2017 at 2:45 a.m. EST (0745 UTC) the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Terra satellite captured a visible image Dineo that showed strong thunderstorms wrapping into and around the "heart" or center of the storm's low-level circulation. A thick band of powerful thunderstorms from the eastern quadrant wrapped south and west into the center.

  • Sunlight or bacteria? Scientists investigate what breaks down permafrost carbon

    A Florida State University researcher is delving into the complexities of exactly how permafrost thawing in the Earth’s most northern regions is cycling back into the atmosphere as carbon dioxide and further fueling climate change.

    Answer: It has a lot to do with tiny little bugs called microbes and little to do with sunlight.

    Assistant Professor of Earth, Ocean and Atmospheric Science Robert Spencer and a team of researchers traveled to Siberia from 2012 to 2015 to better understand how thawing permafrost affected the carbon cycle. They specifically investigated how the vast amounts of carbon stored in this permafrost transferred to the atmosphere as carbon dioxide.

  • El Niño resulted in unprecedented erosion of the Pacific coastline, according to research

    Last winter’s El Niño might have felt weak to residents of Southern California, but it was in fact one of the most powerful climate events of the past 145 years.

  • Climate change impact on mammals and birds greatly 'under-estimated'

    An international study published today involving University of Queensland research has found large numbers of threatened species have already been affected by climate change. 

    Associate Professor James Watson of UQ’s School of Earth and Environmental Sciences and the Wildlife Conservation Society said the team of international researchers found alarming evidence of responses to recent climate changes in almost 700 birds and mammal species.

    “There has been a massive under-reporting of these impacts,” he said.

  • Marine bacteria produce an environmentally important molecule with links to climate

    Scientists from the University of East Anglia and Ocean University China have discovered that tiny marine bacteria can synthesise one of the Earth’s most abundant sulfur molecules, which affects atmospheric chemistry and potentially climate.

    This molecule, dimethylsulfoniopropionate (DMSP) is an important nutrient for marine microorganisms and is the major precursor for the climate-cooling gas, dimethyl sulfide (DMS).

  • Desert Songbirds May Face Expanding Threat of Lethal Dehydration

    AMHERST, Mass – A new study of songbird dehydration and survival risk during heat waves in the United States desert Southwest suggests that some birds are at risk of lethal dehydration and mass die-offs when water is scarce, and the risk is expected to increase as climate change advances.
