Central Asia represents a large swath of the globe's land area where one would expect that the "powerful" temperature impact of humanity's CO2 would be rather robust.
Although the area exhibited warming in the 20th century, it is not much different than earlier warming from periods centuries ago (see graph at bottom).
And there has been a recent late 20th century cooling that is attributed to natural factors.
"[T]he recent cool-moist period from 1985 to 2000 has been related to the Arctic Oscillation...During this recent cool-moist period, ice mass accumulation of the glaciers in the Russian Altai Mountains was observed and Narozhniy and Zemtsov (2011) connected this phenomenon to annual precipitation increased by 8% – 10% especially in winter and spring (April-May) as a result of a strengthening of the zonal circulation over the Altai Mountains.”
Conclusion: Those stubborn facts again get in the way of the catastrophic anthropogenic global warming doomsday claims. Central Asia's warming and cooing during both the past and modern era look to be more a function of natural volcano variations and ocean oscillations.
