• Polar Bears Have Not Been Harmed By Sea Ice Declines In Summer

    • Susan Crockford, Polar Bear Science

    Polar bear numbers overall have increased, despite the appearance of a ‘stable’ global population since 2001 and significant declines in Arctic sea ice coverage in summer.  The polar bear biologists and professional activists of the IUCN Polar Bear Specialist Group (PBSG) continue to insist that since 1979 increasingly smaller amounts of Arctic sea ice left at the end of summer (the September […]

  • New Paper: Tree-Ring Proxy Temperature Data ‘Seriously Compromised’

    • Date: 15/08/13
    • The Hockey Schtick

    More bad news for Michael Mann: A new paper published in Climate of the Pastfinds that ‘modern sample bias’ has “seriously compromised” tree-ring temperature reconstructions, producing an “artificial positive signal [e.g. ‘hockey stick’] in the final chronology.” Needless to say, Mann’s hockey sticks are also seriously compromised by statistical techniques that produce hockey sticks from random numbers, use […]

  • Looming Weak Solar Activity May Herald Frosty Times

    • Date: 10/08/13
    • Space Daily

    The current solar activity cycle, possibly the weakest in 100 years, is approaching its maximum. This may signal a future low period for the sun, probably not unlike the one that caused the so-called Little Ice Age from the mid-16th to mid-19th centuries. The sun is currently at the maximum of Solar Cycle 24, but […]

  • The Sun’s Magnetic Field Is About To Flip

    • Nasa Science News

    Something big is about to happen on the sun.  According to measurements from NASA-supported observatories, the sun’s vast magnetic field is about to flip. “It looks like we’re no more than 3 to 4 months away from a complete field reversal,” says solar physicist Todd Hoeksema of Stanford University. “This change will have ripple effects […]

  • David Whitehouse: Raptures Of The Deep

    • Dr David Whitehouse

    The three briefing papers on the recent pause in global surface temperature released by the UK Met Office this week make interesting reading. They can be found here, here and here. But perhaps unintentionally they say more about the messenger than the actual science, of which there is very little that is new. The overall […]

  • Are Oceans Warming While Global Surface Temperatures Are Stalling?

    • Date: 22/07/13
    • Bob Tisdale, Climate Observations

    The ocean temperature data for the depths of 700-2000 meters is an important topic. With the surface temperatures no longer warming and with the slowdown in the rate at which the oceans are warming at depths of 0-700 meters, climate scientists are now saying the missing heat is being forced to depths below 700 meters. […]

  • Waiting For The Warming

    • Date: 19/07/13
    • Dr David Whitehouse

    Looking back at what was reported in the late 90s and the early years of this century everyone was expecting the rise in global temperature seen in the 90s to continue at an IPCC sanctioned rate of 0.3 deg C per decade. Only years later in the face of no temperature rise was it mentioned […]

  • Polar Ice Melt May Be Natural Event

    • Date: 16/07/13

    Rapid melting of polar ice sheets may be due to short-lived natural events rather than climate change, scientists said. New research suggests more time is needed to predict the likely impact of global warming and ice loss on sea levels. A boat skims through melting ice off Greenland. Picture: AFP The ice sheets covering Antarctica and […]
