A new study indicates that from 4,000 years ago until as recently as 1,500 years ago, or when CO2 levels ranged between 255 and 270 ppm, lake levels in Antarctica were as high as 60 meters above today’s levels. This coincided with “warmer-than-modern paleoclimate throughout the Holocene.”  During the last 2,000 years, Antarctica’s temperatures have … Continue reading Antarctic Temperatures Were ‘Up To 5°C Above Modern’ From 12,000–2,000 Years BP
