My take on George Will's latest. His column was published 1/7/15 in the Washington Post.

Summary: The world's climate has changed a lot over recorded history and before.  These changes have impacted human civilization in major ways.

Quote:

 And if climate Cassandras are as conscientious as they claim to be about weighing evidence, how do they accommodate historical evidence of enormously consequential episodes of climate change not produced by human activity?

Narrative:
In the Medieval Warm Period (800 - 1300) the Earth was warmer than anytime in the last 8,000 years.  Northern England had vinyards.  Then global cooling set in and human upheaval resulted.  Farmland had to be abandoned and people starved.

The Little Ice Age occured in the 17th. century.  1675 was known as "the year without a summer."  Lots of change.

The climate is changing because the climate is always changing.

My Views:
While he goes too far in places, (I doubt that the wars of the 1600's were caused by climate change), this does remind us that climate has changed in the past and the change has not been due to human causes.  The problem that ordinary folks like myself have is that with the large amount of emissions that present society puts into the air it is hard not to think that this would have some impact.  I wonder if global warming is a combination of human and natural causes.

George Will almost didn't make it as a syndicated columnist. His style was considered too erudite for a general audience.

Whatever one thinks of his views, read his work for use of language and for how he marshals facts and uses logic.

Here's his Wiki bio.
