    I find it amusing how whether the "issue" was global cooling or global warming the tactics are the same. The same propaganda was used way back in the 1970's to try and worry the populace about the "impending Ice Age" and lo and behold it's the same players.

    Damn, still the same old lies. Here is the reality of what the scientists were saying in the 1970s.

    And again, the facts.

    http://www.aiacny.org/2009/June/GLOBAL WARMING AND THE ARCHITECT- June 09.pdf

    Scientific studies in the 1970's re: global cooling”
    “Most predictions of an impending ice age came from the popular press (eg - Newsweek,
    NY Times, National Geographic, Time Magazine). As far as peer reviewed scientific papers
    in the 1970s, very few papers (7 in total) predicted global cooling. Significantly more papers
    (42 in total) predicted global warming due to CO2.”

    Global Warming: Fiction: Scientists in the 1970s Were Predicting a Coming Ice Age

    The cooling between 1940 and 1970 was likely a result of industrial pollution that produced sunlight-blocking aerosols, a phenomenon known as global dimming. As industry ramped up across the globe, much air pollution was being spewed out of smoke stacks along with carbon dioxide. This air pollution was blocking incoming sunlight much like that of a volcanic eruption and had the effect of masking the global warming that was well underway. Once clean air legislation began to pass across the globe, air pollution decreased considerably. Sulfate aerosols have declined significantly since 1970 with the Clean Air Act in the United States and similar policies in Europe. The Clean Air Act was strengthened in 1977 and 1990. According to the EPA (2008), from 1970 to 2005, total emissions of the six principal air pollutants, including particulate matter, dropped by 53% in the US. In 1975, the masked effects of trapped greenhouse gases finally started to emerge and have dominated ever since.

    According to Wild, M., Ohmura, A. and Makowski, K. (2007) solar dimming was effective in masking greenhouse warming, but only up to the 1980s, when dimming gradually transformed into brightening. Since then, the uncovered greenhouse effect has revealed its full dimension, as manifested in a rapid temperature rise (+0.38.C/decade over land since mid-1980s). The solar brightening durting that time could not have superseded the greenhouse effect as main cause of global warming, since land temperatures increased by 0.8oC from 1960 to 2000, even though solar brightening did not fully outweigh solar dimming within that period.

    Because of the rapid rate of industrialization of China, India, and other Asian countries in the last few decades, there is still considerable global dimming today. (Recall figure 2.9 that shows aerosols have a direct cooling effect of 0.5 ±0.4 W/m2 and an indirect cooling effect caused by clouds of 0.7 W/m2 with a range between 0.3 and 1.8 W/m2.) If these developing countries pass similar legislation, the rate of global warming will accelerate even faster.

    Two important conclusions can be drawn from this data:

    Human activities can cause global climate change on a relatively short time scale
    Legislation can mitigate that climate change

    Same players? Now if I were a thinking man instead of a partisan hack, I'd be wondering what would have made them change their minds so fast. I can never fathom how the deniers consider this to be evidence for their side. It boggles the mind how they just run away from logic!!!

    How about an even baser reason for changing their minds mr. partisan hack. That being money. If you bothered to even watch the video (which I doubt as that would actually make you have to think about your position and a person who is basing their decisions on "faith" never want to hear actual facts that attack their faith now do they?) you would see that the methods that were being suggested to control the "cooling" were ridiculous and expensive and would have been funded by you guessed it the public.

    The paople involved changed their minds because they saw that the trends were rising and the solar data said that the temps were going to rise and there was no panic amongst the masses. The people couldn't be made to care so there was no money coming to them.

    That is why they changed their minds. But your faith won't allow you to see that simple fact.
