  • Richard Lindzen presentation at Fermilab

    http://vmsstreamer1.fnal.gov/VMS_Sit...0Lindzen/f.htm

    Notes:

    70s and 80s saw some non-scientific organizational activity around 'global warming:

    1) Climate Action Network: coordinating 100s of NGOs
    2) Tyndall Center for Climate Studies and Institute for Climate Impact Research – interlocking directorates

    Arctic Ice: Science being obscured by focus on peak/nadir ice levels.
    Example: Arctic summer temperatures are identical over a 50+ year period – it is the winter temperatures which are variable

    Lindzen comment: Any and every statement is justified by an appeal to authority rather than by scientific argument

    ‘faint sun’ paradox: doubling of CO2 impact on radiative budget = 1.5% to 2% of total energy budget - but during the ‘faint sun’ there was 20% to 30% lower incoming sunlight hence as 20% to 30% smaller budget. Yet temperatures were similar to today.

    Later talk about what CO2 levels are necessary to mimic results? 3 atmospheres of CO2 would be needed - or 10000 times as much CO2 as today. Other accepted differences: no O2 to speak of.

    Data point: 200 w/m2 incoming sun with 50 w/m2 ocean

    IPCC models overview: The models cannot duplicate the ENSO, AMI, PDO – but are said to represent natural variability. The models also cannot simulate the 70s to 90s warming. The reasoning thus is that the difference must be AGW

    Also: why hasn’t sensitivity range from 1.5 to 5 degrees C reduced in 30 years?

    Overview of 11 IPCC GCM model feedback values

    IPCC has no index. Summary doesn’t involve all authors (200 vs 13): "You write 10000 pages – no one reads that. Summary is 20 pages – no one reads that. Press release is 2 sentences and is useless.
    Half-life of CO2?
    Marine geochemical model: 100-150 years
    If AGW emissions are 50 years – then there should be more than ½ of anthropogenic CO2 in the atmosphere. Why the discrepancy? Modellers compensate via a fudging factor.
    Venus and CO2: If you try to calculate Venus’ temperature with CO2 – you get 400 degrees C – 200 degrees less than reality. You need the sulphuric acid cloud.
    Sun spots vs. temperature: no successful attempts to relate sunspots to climate. The relationship between CO2 and temperature is so poor it makes every other method look good. There are some good correlations but still no mechanism.
    How would young scientists contribute? Low noise electronics to be able to use microwaves for tracking. Alternately ERBE with more orbits and better sensors.
    Feedback measurement is days/weeks but is extremely accurate as opposed to long term temperature records.
    CO2 failed to explain the Eocene. Discussion on several papers.

    Only forecast: We will not have an Anthropogenic Climate Disaster

    If you don't want to watch the entire 1.5 hour video (1 hour plus some Q & A), many of the key points above are reused in Dr. Lindzen's presentation to the Heartland institute attached below:
