Petition Project on Global Warming

Found this abstract and the surrounding material today, and it is a MUST READ! Read the whole thing and digest the graphs.

Here's a couple of samples-


Figure 2: Surface temperatures in the Sargasso Sea (with time resolution of about 50 years) ending in 1975 as determined by isotope ratios of marine organism remains in sediment at the bottom of the sea (7). The horizontal line is the average temperature for this 3,000 year period. The Little Ice Age and Medieval Climate Optimum were naturally occurring, extended intervals of climate departures from the mean.



Figure 8: Tropospheric temperature measurements by satellite MSU for North America between 30º to 70º N and 75º to 125º W (dark line) (17, 18) compared with the surface record for this same region (light line) (24), both plotted with 12-month smoothing and graphed as deviations from their means for 1979 to 1996. The slope of the satellite MSU trend line is minus 0.01 ºC per decade, while that for the surface trend line is plus 0.07 ºC per decade. The correlation coefficient for the unsmoothed monthly data in the two sets is 0.92.
