New report on climate change and security

by Judith Curry

Mother Jones has an article entitled “CIA’s Weather Underground.”  Its closing sentence:

In this political climate, it’s no wonder the CIA declined to discuss its global-warming research for this article. For the time being, the climate spooks have gone underground.

The Myth(?) of Easter Island’s Ecocide

by Judith Curry

Update:  response from Jared Diamond.

Several years ago, I read with great interest Jared Diamond’s book Collapse: How Societies Choose to Fail or Succeed. The starkest example in the book was the ecological collapse of Easter Island.

Mark Lynas has written a provocative essay that argues that “recent archaeological work suggests that the eco-collapse hypothesis is almost certainly wrong – and that the truth is far more shocking.

4 degrees

by Judith Curry

John and Michel are hypothetical pub owners in Britain and France.  Lenny Smith asks the following questions:

Can today’s science tell John what +4 degrees would be like for his pub? Or his insurer? (or their reinsurer?) Or better still “climate-proof” his business? Is it a question of mere probabilities? Or might models see a “Big Surprise”? How to best manage Expectations (Theirs) and Credibility (Ours) ? Why is this so hard? Should Michel care about global mean temperature?

Storm surges on the Arctic Ocean coast

by Judith Curry

The latest analysis of sea ice extent by the NSIDC shows that early June sea ice extent is lower than corresponding 2007 value.   A recent article at Yale360 discusses how as Arctic sea ice retreats, storms take toll on the land.

The new geopolitics of food

by Judith Curry

Pursuant to the issues raised on the previous food (in)security thread, I spotted this article published by Lester Brown in Foreign Affairs.  The subtitle of the article is “From the middle east to Madagascar, high prices are spawning land grabs and ousting dictators.  Welcome to the 21st century food wars.”

Climate change and food (in)security

by Judith Curry

A recent NYTimes article highlighted the issue of climate change impact on global food insecurity.  Roger Pielke Jr has criticizes this analysis in several posts [here and here], arguing that recent extreme weather events are not attributable to AGW and that self-reported food insecurity is at odds with model results from the FAO and USDA.   Lets take a deeper look at the issue of food security, and place climate change in a broader context of this complex issue.
