• Melting Glacier Reveals More Evidence Of Very Warm Medieval Warm Period

    • Date: 17/04/20
    • Phys.org

    Melting glacial ice high in the Norwegian mountains has revealed the full extent of the Lendbreen mountain pass, an important trade route from the Roman era until the late Middle Ages. A team of researchers from the Innlandet County Council and NTNU University Museum in Norway and the University of Cambridge in the U.K. has […]

    • Susan Crockford, Polar Bear Science

    From 3-7 April this year, sea ice around Svalbard Norway has been the highest since 1988, but only 6th or 7th highest since records began in the 1970s. Pack ice is year surrounds Bear Island (Bjørnøya) at the southern end of the archipelago for the first time since 2009 at this date, and continues the pattern of high extent […]

  • Rare Ozone Hole Opens Over Arctic — And It’s Big

    • Date: 29/03/20
    • Nature

    Cold temperatures and a strong polar vortex allowed chemicals to gnaw away at the protective ozone layer in the north. A vast ozone hole — likely the biggest on record in the north — has opened in the skies above the Arctic. It rivals the better-known Antarctic ozone hole that forms in the southern hemisphere […]

  • New Paper: Observational Data Point to Less Warming

    • Date: 19/03/20
    • American Association for the Advancement of Science

    An important new study has found that when climate models are constrained by observational data, they yield lower estimates for climate sensitivity. Abstract Future global warming estimates have been similar across past assessments, but several climate models of the latest Sixth Coupled Model Intercomparison Project (CMIP6) simulate much stronger warming, apparently inconsistent with past assessments. […]

  • Arctic Meltdown Put On Ice

    • Date: 06/03/20
    • Paul Homewood, Not A Lot Of People Know That

    Arctic sea ice extent continues to run well ahead of the last few years, as it has done for most of this year so far, and continues to grow at a time of year when it normally begins to stabilise and recede. Average extent in February was the highest since 2013, and stands greater than […]

  • Svalbard Norway Now Has More Polar Bear Habitat Than Two Decades Ago

    • Date: 02/03/20
    • Susan Crockford, Polar Bear Science

    Sea ice around Svalbard, Norway at the end of February 2020 is way above average, as the graph below shows – with more polar bear habitat now than there has been in two decades. Some comparison charts below show that the graph above includes some very high ice years in the 1980s (reaching that dotted […]

  • Staying Power Of Kilimanjaro Snow Defies Al Gore’s Gloomy Forecast

    • Date: 17/02/20
    • The Times

    Kilimanjaro has a habit of defying predictions. Some climate scientists had forecast that all of its icefields and glaciers would have completely melted by now. Yet data suggests a number are stubbornly clinging on, albeit shrunken. Predictions that there would be no more snow on Africa’s highest peak long before we entered this decade spurred […]

  • Arctic Sea Ice Much More Resilient Than Thought

    • Date: 13/02/20
    • Meteorologist Paul Dorian, Perspecta, Inc.

    In recent years the Arctic sea ice has shown great resiliency and is currently at higher levels for this time of year when compared to all but two years going back to 2005.  Overview Sea ice covers about 7% of the Earth’s surface and about 12% of the world’s oceans and forms mainly in the […]
