New Antarctica evidence conclusively refutes IPCC global warming scientists' speculation that modern temperatures are "unprecedented" and "accelerating" higher
Read here. The UN's IPCC attempted to convince the public and policymakers that there was a scientific "consensus" that the last 150 years have witnessed "accelerating" global warming that is "unprecedented."
Instead, the evidence now points to the IPCC and its Climategate scientists conspiring to mislead. Thankfully, the vast majority of the world's scientists do not believe in the IPCC's climate political-science proclamations and thus continue performing/producing empirical research to determine the science truth.
The non-IPCC research team of Thamban et al is an example of this and the adjacent chart (click to enlarge) is a product of their research: Antarctica's modern temperatures are not unusual, nor are they rapidly warming versus what has occurred naturally in the historical past. As the evidence clearly shows, a natural warming has been taking place over the last 400+ years.
"Working with an ice core (IND-22/B4) that had been extracted during the austral summer of 2003 from the coastal region of Dronning Maud Land, East Antarctica... -- the authors developed 470-year histories of δ18O and δD that "showed similar down core fluctuations with [an] excellent positive relationship (R2 = 0.9; n = 216) between the two."..."the estimated surface air temperature at the core site revealed a significant warming of 2.7°C with a warming of ~0.6°C per century for the past 470 years."..."...Thamban et al.'s results clearly indicate that all three of these climate-alarmist claims are false in regard to this portion of the planet's southern polar region."
