So, is it time to become worried when an anti-liberal rag like the Wall Street Journal runs a story like this? (subscriber link)
Global concentrations of CO2 in 2006, not surprisingly then, reached the highest level since the record-keeping began in 1958, the World Meteorological Organization recently announced in its annual greenhouse-gas bulletin. Based on samples from 40 countries, the level of carbon dioxide in the air reached 381.2 parts per million, up fractionally from 2005—concentrations not seen in 650,000 years, scientists said.
You’d think that when a paper as conservative as the Journal starts talking about CO2 levels reaching lower Paleolithic levels, perhaps it’s time to shift debate in the U.S. from “is Global Warming” happening (all the while getting hung up over short- and mid-term noise affecting slower-emerging, long-term trends) to a discussion of the most efficient ways to adapt (probably by some mix of limiting future damage and preparing for a generally warmer world)?
