Government Data Show U.S. in Decade-Long Cooling

By James Taylor, Forbes.com

The National Oceanic and Atmospheric Administration’s most accurate, up-to-date temperature data confirm the United States has been cooling for at least the past decade. The NOAA temperature data are driving a stake through the heart of alarmists claiming accelerating global warming.

Responding to widespread criticism that its temperature station readings were corrupted by poor citing issues and suspect adjustments, NOAA established a network of 114 pristinely cited temperature stations spread out fairly uniformly throughout the United States. Because the network, known as the U.S. Climate Reference Network (USCRN), is so uniformly and pristinely situated, the temperature data require no adjustments to provide an accurate nationwide temperature record. USCRN began compiling temperature data in January 2005. Now, nearly a decade later, NOAA has finally made the USCRN temperature readings available.

Instead, the United States has cooled by approximately 0.4 degrees Celsius, which is more than half of the claimed global warming of the twentieth century.

Of course, 10 years is hardly enough to establish a long-term trend. Nevertheless, the 10-year cooling period does present some interesting facts.
