A new university-led study with NASA participation finds ancient Antarctica was much warmer and wetter than previously suspected. The climate was suitable to support substantial vegetation -- including stunted trees -- along the edges of the frozen continent.
The team of scientists involved in the study, published online June 17 in Nature Geoscience, was led by Sarah J. Feakins of the University of Southern California in Los Angeles, and included researchers from NASA's Jet Propulsion Laboratory in Pasadena, Calif., and Louisiana State University in Baton Rouge.
By examining plant leaf wax remnants in sediment core samples taken from beneath the Ross Ice Shelf, the research team found summer temperatures along the Antarctic coast 15 to 20 million years ago were 20 degrees Fahrenheit (11 degrees Celsius) warmer than today, with temperatures reaching as high as 45 degrees Fahrenheit (7 degrees Celsius). Precipitation levels also were found to be several times higher than today.
- IOW: AGW = TFBS.
- PEOPLE WHO ARGUE THAT CLIMATE CHANGE IS MAN-MADE AND THAT WE NEED TO CURB OUR PRODUCTION OF CO2 ARE DUPES, HUCKSTERS OR SCOUNDRELS.
- PEOPLE LIKE OBAMA - WHO HAS SAID HE WILL MAKE MAN-MADE CLIMATE CHANGE HIS MAJOR GOAL IF HE GETS A SECOND TERM.
