    What I am asking is why it happened. I understand the Earth warmed but why did it warm. Was it because the sun’s output went up or something else? Since there is a great debate now about the climate and its changing, I want to know why it warmed up and why it cooled down to form the ice sheets in the first palce?

    :confused:

    I don't know, but it was surely the fault of humans...and of course cow farts.

    OMFG, You don't even know what caused the fucking ice ages? Hint-> Milankovitch cycles,. They caused a decrease with solar energy within the polar and arctic parts of earth, which allowed for more ice to remain year around. As the ice grew in size and scale it helped lower the avg temperature of the earth, which was a feed back that grew the ice sheets even more.


    Orbit and Axial tilt (obliquity of the earth.) being the main factors. Also what got us into the ice age in the first place 20,000,000 years ago was a decrease in Atmospheric co2. Most likely because of india slamming into Asia. Co2 was as much as 1,200-2,000 ppm 40 million years ago and as high as 3,000 ppm 100-150 million years ago.

    If you can't except this then how the fuck can you except that the earth was ever warmer then today? As the data that gave us the idea above are the same that gave us the thinking that it was much warmer 20, 40, 100 million years ago.

    What got us out of the glacial? Lets just say that the orbit and axial tilt changed to favor more solar energy within the polar and arctic area's of the earth. Same reason that we're shitting our pants about the decrease of arctic sea ice as ice reflects solar energy back to space, while open water takes it up and causes a warming.

    You sound like you might have about the scientific understanding, education and intuitive understanding that I have which ain't much.

    Here is an excellent site for those of us who go comatose at the site of the Periodic Table. It presents the whole argument for both sides using the data in understandable pictures charts and graphs.

    The Milankovitch Cycles are depicted along with the recurring Ice ages and the Interglacials. Interesting stuff.

    Bart.........the k00ks never have a good answer to your question.........the best they do is throw out this "cycle" crap, which doesnt work anymore.......taken a back seat to greenhouse gases. These people have perfected the art of being cameleons.

    OK

    You want a definition for the word "disconnect"? Hang out in this forum for a few weeks.



    Fact is, no warming has occurred since 1998 and the global warming science community has been falling all over themselves to manipulate the data to make it look otherwise.................http://www.businessinsider.com/what-ever-happened-to-global-warming-2011-7.............its become a whole industry.

    So the Earth is on a 400,000 year cycle with mini-cycles inside that. Now the sun has constance output. Therefore we can expect a new ice age shortly. Opps, I mean a hot period until the evil humans are gone.

    :eek:

    Perhaps before displaying your enormous ignorance on this subject, you should try a little research. You have the means right in front of you.

    Lil' bitty particles w-a-y up inna air slowin' down human-induced global warming...

    Study: Upper-Atmosphere Particles Slow Pace of Global Warming
    August 09, 2011 : A recent study finds tiny particles suspended high in Earth’s atmosphere are having a greater impact on global climate than previously believed. The airborne particles, known as aerosols, are blocking radiation from the sun, and that’s cooling the Earth's surface. According to an international team of climate researchers, this cooling has been significant enough over the past decade to slow human-induced global warming.
