Glacier Grows Despite Global Warming, page 1

Okay, now I know why you designated me as a respected foe so no need to respond to my U2U message. Here's the thing. Over 31,000 scientists, including over 9,000 Phds, have signed a petition to Congress that says that there is no conclusive proof that man-made CO2 is causing global warming and that the Kyoto agreement will be a huge mistake. So much for Al Gore's contention that the scientific debate is over and that there's a consensus. Oh I forgot to mention that these 31,000 scientists are ALL American so there are bound to be more worldwide that also agree. Now your contention that glaciers and polar ice caps are melting may have been true up to a couple of years ago but there is conflicting data coming out now. The most recent data for polar ice coverage is that the maximum coverage is 30% larger than the year before. I'm not saying that all glaciers are growing but some clearly are and the only way they can grow is if new accumulations of snow add more mass than is lost by melting. Your contention that CO2 levels have gone up 50% due to manmade sources is a guess. The world's oceans both absorb and give off CO2 depending on water temperature. which is a function of energy received from the sun. When the average temperature of oceans goes up, more CO2 will be released than absorbed and vice versa and the amount of CO2 involved is an order of magnitude larger than even the highest estimates of human produced CO2. If you had bothered to do your homework like I did, you would have come across the report of the scientist who analyzed the ice core samples from Greenland and Antarctica. His data was used by Al Gore to generate the large screen charts covering 600,000 years of temperature and CO2 levels in the movie Inconvenient Truth. In his report, he states quite clearly that average temperature and CO2 levels don't move together. There is a lag of at least 400 YEARS up to a maximum of 1700 years where CO2 lags behind average temperature ie. when the trend changes from up to down or from down to up, average temperature ALWAYS changes direction first and CO2 levels ALWAYS changes direction later. That means that there were periods of at least 4 centuries when average temperatures had already started to drop even while CO2 levels were still rising (because ocean temperatures were still too high). Since the laws of physics and chemistry haven't changed in the last 600,000 years, if rising CO2 levels couldn't stop temperatures from dropping, then they CAN NOT be causing them to rise. Not then and not now. What we're seeing now is the exact reverse. Rising ocean temperatures are CAUSING the rise in CO2 levels. Rising ocean temperatures also by the way explain rising sea levels. Cold water is more dense than warm water so as the oceans warm up, they expand slightly. That can explain the 3mm rise per year even during the three decades from the 1940's to the 1970's when air temperatures were dropping(at the same time that CO2 levels were still increasing I might add). The oceans being so huge take a long time to react to temperature changes due to sheer mass just like a supertanker takes a long time to change direction.

Most of the mainstream media do not report evidence that contradicts manmade global warming so those of you who don't do your homework, are only getting one side of the story. What Al Gore didn't talk about is the previous 3 or 4 spikes in CO2 levels over the last 600,000 years and how CO2 levels dropped on their own due to some natural feedback mechanism. Why do global warming proponents assume that this same natural feedback mechanism won't work again this time?

I'm not saying that climate change isn't a potentially serious issue. What I'm saying is that IF average temperatures are STILL going up, and there is more and more evidence that they are no longer doing so, then it's a natural cycle that we will have to adapt to rather than try to resist.
