Chevrolet Chevelle Forums - Interesting New Data that Al Gore needs to Read

Maybe this'll liven things up a bit.

New facts throws Global Warming theories in the sewer...again.

Most scientists believe that ocean levels dropped for the past 100,000 years as Earth cooled, but a new study of these stalactites in ancient undersea caves suggests otherwise. Today's temperatures are similar to Earth's 81,000 years ago.

Sea levels on Earth change as glaciers grow and shrink, lowering as temperatures cool and more ice forms. According to a release about the study, which appears today in Science:

81,000 years ago, the level of the sea was actually more than a meter above where it stands now, a result seemingly at odds with prevailing ideas about ice sheet growth. Since the sea rises and falls with the melting and forming of large glaciers, respectively, this finding therefore implies that polar ice sheets were smaller and global temperatures were at least as high (or even higher) 81,000 years ago than they are now, even though the concentration of carbon dioxide in the atmosphere was much lower back then. In order to reach these new conclusions, Jeffrey Dorale and colleagues took measurements from a cave formation on the Spanish island of Mallorca which has been intermittently submerged in the Mediterranean Sea over hundreds of thousands of years. Their data suggest that glaciers may grow and shrink faster than experts had believed, and if verified, the results of this study are poised to change the debate over precisely how ice ages come and go.

One possibility is that so-called glacier cycles are not necessarily related to cycles of carbon and methane in the atmosphere.

No kiddin' Sherlock.
