    • The Hockey Schtick

    A paper published today in Nature Climate Change finds that global sea level rise has greatly decelerated 31% since 2002 from 3.5 mm/yr to 2.4 mm/yr. According to the authors, “This decreasing Global Mean Sea Level [GMSL] rate coincides with the pause observed over the last decade in the rate of Earth’s global mean surface temperature increase, […]

    • Ben Webster and Hannah Devlin, The Times

    Rising greenhouse gas emissions may result in better harvests of wheat and soya beans even after allowing for the damage caused to crops by more frequent heat waves, researchers say. Their findings appear at odds with the Intergovernmental Panel on Climate Change, which said in a leaked draft of a report due later this month […]

    The biggest source of climate uncertainty is white and fluffy. In recent years, the uncertainty has actually grown. UP IN THE AIR  Clouds can both warm and cool the planet. How clouds will respond to global warming is the largest source of uncertainty in climate change predictions. From space, clouds appear to perform an intricate and never-ending […]

    Everybody has noticed it: Over the last few months, solar activity has shifted into a higher gear. Since October last year, more and bigger sunspot groups have appeared on the solar disk, gradually driving the monthly sunspot number to new heights. Indeed, in February, preliminary values (SILSO) for the international sunspot number reached 102.8, the […]

    The ice on the Great Lakes this week covered more of the lakes’ surface than at any other time since the record-setting year of 1979, and could break that year’s record this week. The Great Lakes were 90.5 percent ice-covered as of Sunday, the greatest percentage of ice cover since the record-setting year of 1979, according to […]

    • Dr David Whitehouse

    Another week and another explanation for the ‘pause’ in global surface/lower atmosphere temperatures. This time it’s the return of the ‘small volcanoes add up to big effect’ explanation in the form of a paper by Santer et al 2014 in Nature Geoscience. Could the cumulative effect from small volcanoes be causing a reduction in sunlight […]

    • Julie Kent, The Cleveland Leader

    In mid-February 2014, ice cover on the Great Lakes reached 88 percent, levels that have not been observed in 20 years.   Since 1973, the average maximum ice extend is just over 50 percent. It has surpassed 80 percent only five times over the course of the past four decades. The lowest average ice extent […]

  • New Paper: Antarctic Glacier Melted Just As Fast 8000 Years Ago

    • Date: 21/02/14
    • Lewis Page, The Register

    Top boffins from the British Antarctic Survey say that the Pine Island Glacier – famous as a possible major cause of global-warming-powered sea level rises – was melting just as fast thousands of years ago as it is melting today. “This paper [just published] is part of a wide range of international scientific efforts to […]
