Message #696268 from combjelly at 1/30/2013 9:18:58 PM I posted a link to an article that totally refutes what you are claiming. *CO2 lags an average of about 800 years behind* the temperature changes-- confirming that CO2 is not the cause of the temperature increases Here the full article: For more than 2 million years our earth has cycled in and out of Ice Ages, accompanied by massive ice sheets accumulating over polar landmasses and a cold, desert-like global climate. Although the tropics during the Ice Age were still tropical, the temperate regions and sub-tropical regions were markedly different than they are today. There is a strong correlation between temperature and CO2 concentrations during this time. Historically, glacial cycles of about 100,000 years are interupted by brief warm interglacial periods-- like the one we enjoy today. Changes in both temperatures and CO2** are considerable and generally synchronized, according to data analysis from ice and air samples collected over the last half century from permanent glaciers in Antarctica and other places. Interglacial periods of 15,000- 20,000 years provide a brief respite from the normal state of our natural world-- an Ice Age Climate. Our present interglacial vacation from the last Ice Age began about 18,000 years ago. Over the last 400,000 years the natural upper limit of atmospheric CO2 concentrations is assumed from the ice core data to be about 300 ppm. Other studies using proxy such as plant stomata, however, indicate this may closer to the average value, at least over the last 15,000 years. Today, CO2 concentrations worldwide average about 380 ppm. Compared to former geologic periods, concentrations of CO2 in our atmosphere are still very small and may not have a statistically measurable effect on global temperatures. For example, during the Ordovician Period 460 million years ago CO2 concentrations were 4400 ppm while temperatures then were about the same as they are today. Do rising atmospheric CO2 concentrations cause increasing global temperatures, or could it be the other way around? This is one of the questions being debated today. Interestingly, *CO2 lags an average of about 800 years behind* the temperature changes-- confirming that CO2 is not the cause of the temperature increases. One thing is certain-- earth's climate has been warming and cooling on it's own for at least the last 400,000 years, as the data below show. At year 18,000 and counting in our current interglacial vacation from the Ice Age, we may be due-- some say overdue-- for return to another icehouse climate**! And here the link including the plots of temperature vs CO2 changes from the last 400,000 years: geocraft.com CJ, as usual your liberal pseudo science and leftist 'facts' confuse what's left of your brains. /Taro [object]

Last 400,000 years CO2 vs Global Warming "So what's the latest on the issue? To our knowledge, the most recent study to broach the subject is that of Caillon et al. (2003), who measured the isotopic composition of argon -- specifically, ð40Ar, which they argue "can be taken as a climate proxy, thus providing constraints about the timing of CO2 and climate change" -- in air bubbles in the Vostok ice core over the period that comprises what is called Glacial Termination III, which occurred about 240,000 years BP. The results of their tedious but meticulous analysis led them to ultimately conclude that "the CO2 increase lagged Antarctic deglacial warming by 800 ± 200 years." Last 400,000 years CO2 vs Global Warming Facts, CJ. Just facts :) Why don't you Google before you post 'your' opinion about something you don't know doodoo about? Believing only is great and being a strong believer in something, even better. But it is best practised in your church and should be confined to that location. /Taro
