The warmest global climates of the past 65 million years occurred during the early Eocene epoch (about 55 to 48 million years ago), when the Equator-to-pole temperature gradients were much smaller than today1, 2 and atmospheric carbon dioxide levels were in excess of one thousand parts per million by volume3, 4.
... Here we present a well-dated record of early Eocene climate on Antarctica from an ocean sediment core recovered off the Wilkes Land coast of East Antarctica. The information from biotic climate proxies (pollen and spores) and independent organic geochemical climate proxies (indices based on branched tetraether lipids) yields quantitative, seasonal temperature reconstructions for the early Eocene greenhouse world on Antarctica. We show that the climate in lowland settings along the Wilkes Land coast (at a palaeolatitude of about 70° south) supported the growth of highly diverse, near-tropical forests characterized by mesothermal to megathermal floral elements including palms and Bombacoideae.HIGH TEMPS AND HIGH CO2 AND NOT AN SUV OR HUMAN IN SIGHT FOR 50 MILLION YEARS!
IOW: CLIMATE CHANGE - AND EVEN CHANGES IN ATMOSPHERIC "GHG'S" - IS NATURAL.
ALWAYS HAS BEEN.
IOW: MAN-MADE GLOBAL WARMING AND MAN-MADE CLIMATE CHANGE IS TFBS.
