    Nicola Scafetta (2013) Discussion on climate oscillations: CMIP5 general circulation models versus a semi-empirical harmonic model based on astronomical cycles, Earth-Science Reviews 126 (2013) 321–357 Abstract: Power spectra of global surface temperature (GST) records (available since 1850) reveal major periodicities at about 9.1, 10–11, 19–22 and 59–62 years. Equivalent oscillations are found in numerous multisecular paleoclimatic records. The Coupled Model […]

  • Did The IPCC AR5 Take The ‘Dangerous’ Out Of Global Warming?

    • Date: 04/10/13
    • Judith Curry, Climate Etc.

    Abrupt changes that aren’t really abrupt and irreversible changes that aren’t really – er – irreversible. Catastrophe? Er – we don’t know. Section 12.5.5 in the WG1 Report provides some important insights on what is most commonly regarded as the ‘dangerous’ aspects of AGW. For background on this topic, see this previous Climate Etc. post Redefining dangerous climate […]

    For the Swiss Alps 2013 was a good summer. Not since ten years ago have the glaciers lost as little mass as this year. And some seem to be gaining a little weight.   «It would appear that the Findel glacier is gaining mass», says Swiss glaciologist Matthias Huss. Foto: Keystone The Findel glacier high above […]

  • David Whitehouse: Don’t Mention The ‘Pause’

    • Date: 27/09/13

    The press conference associated with the release of the AR5 Summary for Policymakers was notable by the elephant in the room – the lack of warming the surface of the world has experienced over the past 16 years. Many observers have called this fact ‘the greatest problem in climate science,’ and it certainly is its […]

  • David Whitehouse: ‘Pause’ For Thought

    • Date: 23/09/13
    • Dr David Whitehouse

    The media’s handling of the ‘pause’ in global surface temperature has been a failure for science communication and science journalism.   This week’s IPCC AR5 report will state that the ‘pause’ in the global land and sea surface temperature observed since 1997 is a real and unexplained phenomenon, despite the IPCC’s head Rajendra Pachauri’s puzzling […]

  • Climate Consensus ‘Skewing’ Science

    • Date: 20/09/13
    • Graham Lloyd, The Australian

    CONSENSUS decision-making on climate change has oversimplified the problem and how to solve it, and unduly politicised the process, a leading US climate scientist has said. Writing in The Weekend Australian today, Judith Curry, professor and chairwoman of the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology, said the consensus-building process […]
