    Often we see posted on this board how wildly erroneous Dr. James Hansen's predictions have been. Almost always without any supportive links. So what is Dr. Hansen's record on his predictions. Here is one from an early paper in 1981. The whole paper is available at the link.

    http://thedgw.org/definitionsOut/..\docs\Hansen_climate_impact_of_increasing_co2.pdf

    Summary. The global temperature rose by 0.20C between the middle 1960's and
    1980, yielding a warming of 0.4°C in the past century. This temperature increase is
    consistent with the calculated greenhouse effect due to measured increases of
    atmospheric carbon dioxide. Variations of volcanic aerosols and possibly solar
    luminosity appear to be primary causes of observed fluctuations about the mean trend
    of increasing temperature. It is shown that the anthropogenic carbon dioxide warming
    should emerge from the noise level of natural climate variability by the end of the
    century, and there is a high probability of warming in the 1980's. Potential effects on
    climate in the 21st century include the creation of drought-prone regions in North
    America and central Asia as part of a shifting of climatic zones, erosion of the West
    Antarctic ice sheet with a consequent worldwide rise in sea level, and opening of the
    fabled Northwest Passage.

    So you're saying he is correct? All this happened and increased CO2 made it happen?

    It was 50 degrees this morning - late April in Florida. I've never seen that before.

    So, you get your science from Time magazine?

    So what Exit DID Frank take?

    Oh and it's too bad we didn't beat the Soviets.

    So that's 0 for 2 on the left's predictions in 1977

    What were climate scientists predicting in the 1970s?

    The fact is that around 1970 there were 6 times as many scientists predicting a warming rather than a cooling planet. Today, with 30+years more data to analyse, we've reached a clear scientific consensus: 97% of working climate scientists agree with the view that human beings are causing global warming.

    LOL......all the k00k predictions in the past 5 or 6 years have fallen flat on their face...........which is exactly why the whole green movement is moving at a snails pace.

    The public gets this shit now.........I posted up the new Pew poll the other night ( concerns of the voters). Global warming isnt even on the list of the 20 top concerns anymore. Its now only an internet hobby thing........

    Already have many times. A few scientists looked at the decreasing temperatures in the 60s and early 70s without factoring in the aerosols. And predicted an imanant ice age. The press picked it up and ran with it. Over six times as many scientists predicted warming because of the increasing GHGs. The OP has the predictions made by Dr. Hansen in 1981. Predictions for this century, many of which have already happened.
