Roy Spencer, climatologist, former NASA Scientist

Roy W. Spencer received his Ph.D. in meteorology at the University of Wisconsin-Madison in 1981. Before becoming a Principal Research Scientist at the University of Alabama in Huntsville in 2001, he was a Senior Scientist for Climate Studies at NASA’s Marshall Space Flight Center, where he and Dr. John Christy received NASA’s Exceptional Scientific Achievement Medal for their global temperature monitoring work with satellites. Dr. Spencer’s work with NASA continues as the U.S. Science Team leader for the Advanced Microwave Scanning Radiometer flying on NASA’s Aqua satellite. He has provided congressional testimony several times on the subject of global warming.

Dr. Spencer’s research has been entirely supported by U.S. government agencies: NASA, NOAA, and DOE. He has never been asked by any oil company to perform any kind of service. Not even Exxon-Mobil.

Dr. Spencer’s first popular book on global warming, Climate Confusion(Encounter Books), is now available at and

How Nations Recover

I’ve been especially interested in the way Britain revived itself between 1820 and 1848. Its comeback has some humbling lessons for us today.

Britain was roiled by economic and demographic changes. There were financial crises, bad harvests and a severe depression. There was crushing inequality. The average life expectancy nationwide was 40, but in the industrial cities of Manchester and Liverpool it was around 28.

.. The Chartists cohered around The People’s Charter, which had six demandsincluding universal male suffrage, vote by ballot and equal electoral districts. In 1842, the Chartists presented a petition to Parliament with three million signatures.

.. Finally, there was the Anti-Corn Law League. This was the best organized and best funded pressure group in 19th-century Britain. It promoted free-trade legislation to reduce the power of the landed gentry, to make food cheaper for the working classes and to encourage international exchange and cooperation.

..  Britain was blessed by a stable parliamentary system and by a legislative culture that valued deliberation and debate. Political leaders in both parties understood that the winds of change were blowing and they had better initiate reforms if they wanted to head off a revolution.

The Pessimistic Meta-Induction from the History of Science

.. because so many scientific theories from bygone eras have turned out to be wrong, we must assume that most of today’s theories will eventually prove incorrect as well. And what goes for science goes in general. Politics, economics, technology, law, religion, medicine, child-rearing, education: no matter the domain of life, one generation’s verities so often become the next generation’s falsehoods that we might as well have a Pessimistic Meta-Induction from the History of Everything.

.. The idea behind the meta-induction is that all of our theories are fundamentally provisional and quite possibly wrong. If we can add that idea to our cognitive toolkit, we will be better able to listen with curiosity and empathy to those whose theories contradict our own.
