The source that I found to be most interesting was the extensive "globalwarminghoax.com" particularly their documentary titled, "The man-made Global Warming Hoax." As you might expect this organization directly opposes the theory that global climate change is caused by human interaction, and supports the theory that gradual climate change is nothing new, and is completely natural.
A major argument is that if the Co2 increases in the atmosphere as a greenhouse gas, than the temperature will rise. General consensus is that the levels of Co2 are at an all time high, which would in-turn mean a serious problem. To refute this idea, the documentary uses several arguments. One argument is that the co2 levels were this high before, during the Holocene Maximum period (7-4 thousand years ago), which means it has little to do with pollution, plus it lasted 3 thousand years. These "warm periods" have occurred frequently throughout the past, and climatologists refer to them as 'hypsithermals".
Back to the idea that high-levels of co2 raise the earths temperature; the researchers in the film lay out a time-line of the 20th century, and we are shown the steady increase in temperature. The information proves that there has definitely been a an obvious increase in temperature, but at the opposite times you'd expect. The majority of increase takes place prior to the 1940's, which is significant because this is before the industrial revolution got underway, which theoretically should have been the reason for a heavy increase of co2 in the earth's atmosphere. And what happens during the post-war economic boom? When thousands of corporations were pumping out unrefined emissions by the day? the earths temperature decreased! So again it's far from black and white when it comes to the actual answer in co2 levels.
This comes up again in the mention of the "Ice core." What is the ice core?(I asked myself)
The ice core- is a record of environmental surface activity, depending on periods of extended sunlight, where surface snow can form in different layers in the Arctic. ---"The ice cores can provide an annual record of temperature, precipitation, atmospheric composition, volcanic activity, and wind patterns. In a general sense, the thickness of each annual layer tells how much snow accumulated at that location during the year." ---Paleoclimatology the ice core record.
A very interesting argument, and it was surprising to me that so much opposition towards the case of global warming was coming from Europe, and majority of the scientists were from the UK.

This article seems very interesting. The part about the Co2 is an argument that I have heard before. My understanding is that while there has been periods of fluctuation between warm and cool; it's more alarming at how quickly we have reached the point that we are at compared to past records.
ReplyDeleteAs someone fairly uninformed on the science of global warming, this is a compelling counter argument to the environmentalist endeavor. The site gives a tangible argument in its statement that CO2 levels don't line up with historically industrial/polluting periods, which is a couple steps above the hollow and overly general 'climate change is natural' argument. Of course, this could simply be a matter of attributing an incorrect cause to an observed effect.
