Blocking the Sky to Save the Earth
To the relief of climate scientists around the world, it appears that the polar ice cap hasn’t shrunk as much this summer as it did last summer.

What should we do with the carbon we produce when we burn fossil fuels? Some experts say we should fight climate change by putting the carbon back underground, whence it came.

A few years ago, these scientists regarded global warming as a matter of serious concern; now many appear to think that it’s a matter of grave urgency – that we may be running out of time. The recent Intergovernmental Panel on Climate Change (IPCC) reports are increasingly viewed as out of date.
The Arctic ice cap melted this summer at a shocking pace, disappearing at a far higher rate than predicted by even the most pessimistic experts in global warming. But we shouldn’t be shocked, because scientists have long known that major features of earth’s interlinked climate system of air and water can change abruptly.
On July 18, the National Petroleum Council delivered a blockbuster report to the US Secretary of Energy. The council advises the US federal government on energy issues. The council’s report—entitled Facing Hard Truths about Energy—assesses the “future of oil and natural gas to 2030 in the context of the global energy system.” Its 400 pages reveal a major shift in the energy industry’s publicly stated views about humankind’s energy prospects: We’re running out of cheap oil.
Thomas Homer-Dixon writes here on causality in complex systems, in response to Alex de Waal’s earlier post Is Climate Change the Culprit for Darfur? and to Declan Butler’s June 28th Nature article Darfur’s climate roots challenged.
DOES climate change threaten international peace and security? The British government thinks it does. As this month’s head of the United Nations Security Council, Britain convened a debate on the matter last Tuesday. One in four United Nations member countries joined the discussion — a record for this kind of thematic debate.
If we unleash Canada’s capitalist creativity, we could be an international leader in a suite of technologies urgently needed in a warming world that will depend on fossil fuels for many decades. These include technologies for the clean combustion of coal, for storing carbon dioxide underground, and for using hydrogen as a transportation fuel. We could make staggering amounts of money selling these technologies around the world.
What is the relationship between environmental stress—especially shortages and degradation of cropland, forest stocks, and supplies of fresh water—and civil violence in developing countries, including insurgency, ethnic strife, and revolution?
