Bill Frezza interviews Richard Lindzen on Real Clear Radio Hour on February 12, 2016. Atmospheric physicist and MIT Professor Emeritus Richard Lindzen was the lead author of the “Physical Climate Processes and Feedbacks” chapter of the IPCC Third Assessment Report. Lindzen attributes climate hype to politics, money, and propaganda particularly taking issue with the “97% consensus” claim that is being used to stifle debate and demonize skeptics.
Recent satellite records have revealed a global greening process over drylands, but to date, the reasons for this greening have been somewhat of a mystery. A new study just published on nature.com on February 12, 2016 by authors Xuefei Wang, Lixin Wang and Matthew F. McCabe concludes that
…higher concentrations of atmospheric CO2 induce plant water saving and that consequent available soil water increases are a likely driver of the observed greening phenomena.

Frozen rivers, knee-deep snows, sleet, frigid temperatures, and other winter miseries helped shape the story of George Washington’s life.

So my question is this. Why are we defining ‘dangerous climate change’ with respect to the climate of the 18th century, which was the coldest period in the last millennia, with wicked winters? Why not use a reference point of 2000 or 1970? The IPCC doesn’t provide a convincing explanation for the overall warming between 1750 and 1950; according to climate models, human causes contributed only a very small amount to the global warming to during this period (so presumably this overall warming was caused by natural climate variability). Co-opting the period between 1750 and 1950 into the AGW argument muddies the scientific and the policy waters.
Anyone interested in a science-based understanding of Climate Change and the current state of the science, should read Dr. John R. Christy’s testimony before the U.S. House Committee on Science, Space & Technology from yesterday.
