- accelerated significantly over the 20th century; is
- unprecedented with respect to the past millenium and
- should be greatly amplified in the earth's polar regions
What was learned
In the words of the four Indian researchers, "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."
What it means
Climate alarmists have long predicted that CO2-induced global warming -- which they claim has (1) accelerated significantly over the course of the 20th century and is (2) unprecedented with respect to the past millennium or more -- should be (3) greatly amplified in earth's polar regions. However, 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.
