Waving Goodbye to the 2°C Threshold: The Post-Copenhagen Reality

By Chip Knappenberger -- May 5, 2010

If your goal is keeping the earth’s temperature rise below 2°C, the only thing you have left is hope. Hope that the climate sensitivity—how much the global temperature rises from an increase in greenhouse gas concentrations—is far beneath what the climate models calculate it to be. When it comes to trying to use emissions cuts to achieve the 2°C goal, the cat is already out of the bag—maybe not in terms of emissions-to-date, but almost certainly so for emissions-to-come.

Such is the conclusion implicit in the recent analysis by Joeri Rogelj and colleagues published in a recent issue of Nature magazine.

Rogelj et al. did yeoman’s work in collecting all the varied (non-binding) efforts pledged by all of the various countries of the world to reduce their greenhouse gas emissions under the Copenhagen Accord that came out of last December’s big United Nations Climate Conference.…

Waxman-Markey: Inconsequential for Sea-Level Rise, Too

By Chip Knappenberger -- July 30, 2009

The American Clean Energy and Security Act, better known as the Waxman-Markey Climate Bill, has been shown to be completely ineffective at slowing the rise in global temperature that is projected by climate models to accompany mankind’s continued reliance on fossil fuels for energy production. And this, despite the bill’s mandated cut-back of U.S. greenhouse gases emissions by a whopping 83% below 2005’s levels by the year 2050. As the primary purpose of the bill is to mitigate “global warming” and any follow-on impacts, Waxman-Markey, on its own, would seem an abject failure.

If you need any more proof, consider the bill’s effect on projected sea level rise. Recall that the specter of rapid sea level rise is one of the pillars of alarmist claims for impending climate catastrophe and calls for immediate action.…
