More Inconvenient Truths

Yesterday, the Obama Administration released a long awaited, definitive government report on the impact of climate change on the United States by region, economic sector and social outcome.  In what might be called an American version of the Stern report, prepared by 13 government agencies, it confirms the large existing body of scientific work on the reality of climate change and then specifically charts the impact on the United States today and far into the future.

Significantly, it argues that climate change has already impacted the US through heavy downpours, rising temperatures and sea levels, thawing permafrost, earlier snowmelt and alterations in river flows.  And change will accelerate in years to come.  Indeed, the report underscores that much of the impact of climate change will be via water.  In some areas, increased precipitation will stress water management resources, leading to flooding.  In others, it will lead to drought.  Changing water paterns will impact agriculture, coastal regions and public health.

If this report cannot drive home the point that the cost of climate change is far greater than the cost of a cap and market regime to address it, nothing may.  The real threat of climate change is that its mechanism for wreaking havoc is so broad: rain, rising rivers, drought and other changes in our overall habitat can seem too diffuse to pin on one cause.  This report shows that there is a cause, however, and it is greenhouse gases.

As the House prepares to debate the American Clean Energy and Security Act (ACES) next week it would do well recognize that the problems of climate change do indeed transcend regional or parochial boundaries and only the political courage to see the big picture, will enable America and the world to take the steps needed to solve this complex problem.
