On his trans-Arctic journey aboard an icebreaker ship, global systems professor Thomas Homer-Dixon notes the increasing patchwork of open water and small ice chunks where formerly there had been one continuous expanse of 8 foot thick sea ice. His observations highlight scientists’ claims of accelerating climate change that is hitting the Arctic twice as fast as anywhere else.
Writing in an op-ed in today’s New York Times (‘Disaster at the Top of the World’), professor Homer-Dixon suggests that a reluctance to implement effective climate change policies–particularly in the U.S.–is the result of a perceived challenge or threat to our identity. Referencing Yale University professor Dan Kahan’s theory of “protective cognition”, and noting the exploitation of identity threats by powerful coal and oil interests, Homer-Dixon asserts “we’ll almost certainly need some kind of devastating climate shock to get effective climate policy.”
Though noting the Kennedy School of Government’s recent study (‘Responding to Threat of Climate Change Mega-Catastrophes’), the author cites a general lack of adequate and realistic plans in place to deal with an acute climate crisis and calls for “aggressive preparation”
Homer-Dixon goes on to ask the difficult questions that will inevitably arise, such as: where will the money come from to rapidly over-haul the world’s energy systems? Homer-Dixon acknowledges that there will be different climate impacts in different parts of the world and questions whether poorer nations will be able to adapt quickly enough to forestall wide-spread devastation and/or a consequent armed conflict (such as from a major crop failure or drought).
He also brings up the controversial issue of geo-engineering and who will undertake these operations (such as injecting sulfates into the upper atmosphere to cool the planet).

This is the second, rather alarmist (perhaps necessarily so), climate-related op-ed to appear in the NY Times in two weeks. The first, ‘The Sun Also Surprises’ penned by Lawrence E. Joseph, focused on the likely, negative impacts to agriculture, infrastructure and communications during a future phase of high solar activity (sunspots, flares, etc.). That op-ed may be found here
As I conclude this post, I will note that the floods in Pakistan, and more recent ones in Northeast China, continue.

Michael Ricciardi is a well-published writer of science/nature/technology articles and essays, poetry and short fiction. Michael has interviewed dozen of scientists from many scientific fields, including Brain Greene, Paul Steinhardt, and Nobel Laureate Ilya Progogine (deceased). Michael was trained as a naturalist and taught ecology and natural science on Cape Cod, Mass. from 1986-1991. His first arts grant was for production of the environmental (video) documentary 'The Jones River - A Natural History', 1987-88 (Kingston, Mass.). Michael is also an award winning, internationally screened video artist. Two of his more recent short videos; 'A Time of Water Bountiful' and 'My Name is HAM' (an "imagined memoir" about the first chimp in space), and several other short videos, can be viewed on his website (http://www.chaosmosis.net). Michael currently lives in Seattle, Washington.
