Byron York writes at Human Events:
Given how deeply the IPCC is invested in the issue — it shared the Nobel Peace Prize with Al Gore in 2007 — there’s little doubt the report will give environmental activists at least something to work with. For example, it appears IPCC scientists will declare even more forcefully than before that they are absolutely certain human activity is causing warming. They will repeat previous calls for action against warming on a global scale. There will still be dire warnings.
But the political debate will change. There’s no way Congress will consider upending the American economy with far-reaching tax or regulatory schemes on the basis of flawed computer projections about a phenomenon that may or may not require any action at all. The activists can produce as many ads as they want. They can call opponents “deniers” all they like. It just won’t work.
