following the most recent science... it looks like this... the oceans are warming a bit. change in co2 matches but lags the change in ocean temps. Is it natural, is it the sun, is it underwater volcanoes, is it something man is doing? Note... its very unlikely co2 is causing the oceans to warm. As the oceans warm the out gas co2. http://www.climatechangedispatch.co...ture-rises.html In a study recently published in Global and Planetary Change, Humlum et al. (2013) introduce their analysis of the phase relation between atmospheric carbon dioxide concentration and mean global air temperature by noting that over the last 420 thousand years, "variations in atmospheric CO2 broadly followed temperature according to ice cores, with a typical delay of several centuries to more than a millennium," citing Lorius et al. (1990), Mudelsee (2001) and Caillon et al. (2003). And they explain this relationship by stating it "is thought to be caused by the slow vertical mixing that occurs in the oceans, in association with the decrease in the solubility of CO2 in ocean water, as its temperature slowly increases at the end of glacial periods (Martin et al., 2005), leading to subsequent net out-gassing of CO2 from the oceans (Togweiler, 1999)." So if this be true for glacial cycles, should it not also be true for seasonal cycles? Feeling that such might indeed be the case, the three Norwegian researchers intensively studied the phase relations (leads/lags) between atmospheric CO2 concentration data and several global temperature data series - including HadCRUT, GISS and NCDC surface air data, as well as UAH lower troposphere data and HadSST2 sea surface data - for the period January 1980 to December 2011. And what did they find? Humlum et al. report that annual cycles were present in all of the several data sets they studied and that there was "a high degree of co-variation between all data series ... but with changes in CO2 always lagging changes in temperature." More specifically, they state that "the maximum positive correlation between CO2 and temperature is found for CO2 lagging 11-12 months in relation to global sea surface temperature, 9.5-10 months [in relation] to global surface air temperature, and about 9 months [in relation] to global lower troposphere temperature," so that "the overall global temperature change sequence of events appears to be from the ocean surface to the land surface to the lower troposphere."

if you really examine your chart the data shows co2 trails temperature. see the study I cited above... you can then download the data and see for yourself that change ocean temps lead change in co2
There is no lag. CO2 and temps rise essentially rise simultaneously when CO2 is the driving factor. You know why?
So far, I know why... its because so far its only in your mind. You have produced no science showing this when asked. First antarctica warmed... then co2 got released and then co2 climbed. That is the historical record. That is the current day record. Just looking at the monthly data.
OK. You win. Here is the science showing CO2 leads temps higher. Now you can't say I did not show you the science.
EVERY SCIENCE ORGANIZATION IN THE WORLD EXXON BP THE WEATHER CHANNEL NOAA NASA THE MET OFFICE The science is clear, overwhelming and obvious. Man's release of greenhouse gasses - mostly CO2 - has increased the greenhouse effect of earth's atmosphere which has caused heating of the earth and it continues to increase unabated. There is nearly unanimous agreement among the world's science community and the experts are in 97% consensus about this. Anyone currently denying AGW is an idiot. Period. Or a Republican, same thing.
you are simply a lying ignorant drone. posting the same chart when you are aware the monthly data shows temps lead co2. http://www.climatechangedispatch.co...ture-rises.html In a study recently published in Global and Planetary Change, Humlum et al.
