    This graphic is of Northern Hemisphere summer temperature anomalies, comparing the last 3 decades to the average of the previous 3 decades.



    It's included in this item Must-Read Hansen: 'Climate Change Is Here giving us all a heads up on a new paper.

    The paper's being released on Monday 6 August (USA time). Unlike some other papers, this one relies on records of temperature anomalies that have already occurred rather than models or projections of what might occur in various circumstances.

    Have a look at it and then we'll all be ready when the full paper is released, even though it might be a bit of a challenge to
    a) get access to it at all .... and/or
    b) make sense of the paper when we do get to read it.

    OK. Everyone's getting in on the act. Hansen on the New Math of Extreme Events Climate Denial Crock of the Week

    This ClimateCrocks piece has a brief interview with Dr Hansen. More importantly, you should look at the link to Hansen and Sato's layman's overview of the paper. That's got a few nice graphs too.

    I'm not sure why this is really considered a discussion anymore. I'm only going by the fact that no one is posting to the contrary, but it seems like the vast majority of climate-educated individuals are in agreement.

    This study looks well done. Thanks for posting it.

    nice - does it say whether this is worldwide or restricted to a particular part of the globe ?

    This particular set of graphs applies to summer (JJA) in Northern Hemisphere only.

    If you want more details there's a reasonably good discussion here.

    adelady, a one line Summary of your Thread would be appreciated. What you see as a possible explanation of what might be going on. I like Site References and I thank you for them, but sometimes I just need to know the basic prognosis as I guess I can get lost in the detail. westwind. ( at this time of the day ).
    Words words words, were it better I caught your tears, and washed my face in them, and felt their sting. - westwind

    One line? Maybe a couple of very long lines. (It's all about energy.)

    150 years ago every square metre of the earth's surface had 4 kilograms of CO2 in the atmosphere above it whereas now there are 6 kilograms of CO2 in that volume of atmosphere.

    Because CO2 both inhibits energy leaving the atmosphere and redirects energy back to the surface that extra 2 kg means there's just more energy available within the earth's surface, oceans, ice and atmosphere to drive heat, melting, storms - all the weather and climate driving forces have more energy behind them.

    More and more rapid evaporation, more and more rapid condensation mean more drought and more floods - sometimes in the same places a few months apart, more often they're in separated places at the same time (think Russia and Pakistan a couple of years ago).
    KALSTER and WorldCitizenUSA like this.

    but anyway, why we need to be so much worried when extreme temperature is real! i mean should we ignore altogether the effect of extreme temperature around us?!
