| Description | NOAA’s Global Monitoring Division reports that global concentrations of the primary heat-trapping greenhouse gas, carbon dioxide, jumped 2.28 ppm in 2008.
A study in Science from the Global Carbon Project (see “More on soaring carbon concentrations“) noted:
The present concentration is the highest during the last 650,000 years and probably during the last 20 million years.
Worse, the rate of growth of CO2 concentrations this decade is 2.1 ppm a year — 40% higher than the rate from the 1990s. At the same time that CO2 emissions are soaring, CO2 sinks are saturating (see “The ocean is absorbing less carbon dioxide“).
This post is based on preliminary data for 2008 from NOAA’s network of air sampling sites. Reuters has a story based on sampling off northern Norway, which wins the prize for the most confused climate article of the year, starting with the headline: |
