• Not Even The Global Covid-19 Disaster Will Make A Big Difference To Atmospheric CO2 Levels

    • Date: 18/05/20
    • Roy Spencer blog

    Why the current economic slowdown won’t show up in the atmospheric CO2 record Summary: Atmospheric levels of carbon dioxide (CO2) continue to increase with no sign of the global economic slowdown in response to the spread of COVID-19. This is because the estimated reductions in CO2 emissions (around -11% globally during 2020) is too small a […]

  • Is Global CO2 Fertilisation Cooling The ‘Greenhouse Effect’?

    • Date: 15/05/20
    • Patrick J Michaels, Climate Etc.

    A new paper finds higher than expected CO2 fertilization inferred from leaf to global observations.  The paper predicts that the Earth is going to gain nearly three times as much green matter as was predicted by the IPCC AR5. Earlier this month, I posted a short piece about an explosive paper on planetary greening that appeared in the […]

    The warm start to 2020 is mostly the product of one region – Siberia. And Siberia is on fire as never before. It has been reported widely that as far as the global temperature goes 2020 has gotten off to a very warm start with a temperature possibly second only to the strong El Nino […]

  • Canada’s Cool-Headed Antidote To Hot Arctic Alarmism

    • Date: 30/04/20
    • Terence Corcoran, Financial Post

    A new government report by Canada’s Department of Fisheries and Oceans is a welcome cool-headed antidote to the sensational portrayal of the Arctic as a melting disaster that’s killing polar bears. We now leave this southern coronavirus hell to take you way, way up North to the Canadian Arctic where, according to a news report, “the […]

  • 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. […]
