Koch-Funded Study Finds Recent Global Warming “On the High End” and Speeding Up

A recent Koch-funded study has been released that finds that “global land temperatures have increased by 0.911 ± 0.042 C since the 1950s”. The study reports, “this data is consistent with previous global land-surface warming results, but with reduced uncertainty.”

“The study found that the average land temperature from Jan 1950 to Dec 1959 was 8.849 ± 0.033 C (47.93 degrees Fahrenheit), and that the temperature average during the most recent decade (Jan 2000 to Dec 2009) was 9.760 ± 0.041 C (49.57 degrees Fahrenheit)  — an increase of 0.911 ± 0.042 C.”

“The trend line for the 20th century was calculated to be 0.733 ± 0.096C/century, well below the 2.76 ± 0.16 C/century rate of global land-surface warming that was observed during the interval of Jan 1970 to Aug 2011.” (In other words, in the past 40 years, the land has warmed nearly 4 times faster than it did in the last cen­tury.)
