Underground Caves Suggest Temperature Today Is Like Earth 81,000 Years Ago

Apparently, according to some scientists and a study, today's temperatures are similar to Earth 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.
