Dialing Back the Alarm On Climate Change

An anonymous reader writes "A leaked copy of a report by the Intergovernmental Panel on Climate Change (IPCC) has made the rounds and the good news is that the predicted temperature rise expected as a result of man-made emissions of carbon dioxide is lower than predicted in 2007. From the article: 'Admittedly, the change is small, and because of changing definitions, it is not easy to compare the two reports, but retreat it is. It is significant because it points to the very real possibility that, over the next several generations, the overall effect of climate change will be positive for humankind and the planet. Specifically, the draft report says that "equilibrium climate sensitivity" (ECS)—eventual warming induced by a doubling of carbon dioxide in the atmosphere, which takes hundreds of years to occur—is "extremely likely" to be above 1 degree Celsius (1.8 degrees Fahrenheit), "likely" to be above 1.5 degrees Celsius (2.4 degrees Fahrenheit) and "very likely" to be below 6 degrees Celsius (10.8 Fahrenheit). In 2007, the IPPC said it was "likely" to be above 2 degrees Celsius and "very likely" to be above 1.5 degrees, with no upper limit. Since "extremely" and "very" have specific and different statistical meanings here, comparison is difficult.'"

    The CO2 graph (direct measurement) is clearly climbing at a never-before-seen rate. How does this compare to the conclusions in the report?

  2. Ignore the evidence by huckamania · · Score: 4, Interesting

    Ignore the pause, ignore the missing heat, ignore the solar cycles, ignore the lack of sea level rise, ignore an arctic that is not ice free, ignore ENSO effects, ignore weather stations next to tarmacs, ignore urban heating, because they don't match the models.

    Ignore the money being made, ignore the cost to society, ignore the lack of true peer review, ignore the missing data, ignore academic misconduct, ignore the denied FOI requests, ignore the emails, because that is just human nature.

    When you are blind, everything is 'Nothing to see here, move along'...

    There's a big omission in Spencer's graph - datasets of ground-based temp measurements.
    The satellite readings have always been cooler and have needed numerous adjustments one way or the other.
    If he were thinking like a scientist and not a regulator, he'd incorporate other observation-based data instead of taking the satellite measurements as, well, gospel.

  4. Billions of tons [Re:Excellent!] by Geoffrey.landis · · Score: 4, Interesting

    When Obama flies around nilly-willy on Air Force One he dumps tons of greenhouse gases into our atmosphere. Are you saying there's no climate change when he does that?

    Have you ever heard of a form of ignorance called innumeracy? No? You should, because you have it.

    If, in fact, flying Air Force One (which all presidents fly in, not just Obama, of course) dumps merely tons of greenhouse gas into the atmosphere, yes, that would be irrelevant to climate change. If it dumped thousand of tons, that would be irrelevant. If it dumped millions of tons, that would be irrelevant.

    Do you have the slightest idea how many tons of carbon dioxide are put in the atmosphere by humans every year?
