A new paper published in The Holocene finds the Antarctic interior was warmer than the present over a period lasting about 2000 years, from 4300 to 2250 years ago. The paper surveys 3 lakes within 10° of the South Pole and finds meltwater levels were up to 69.5 meters higher than the present, which the authors “interpreted as being the result of an increased number of meltwater events and/or degree-days above freezing, relative to the present.” The paper adds to many other peer-reviewed papers demonstrating that Antarctica has warmed for prolonged periods to temperatures higher than the present, and that there is nothing unusual, unnatural, or unprecedented in regard to present day temperatures.
