According to measurements by The National Oceanic and Atmospheric Administration (NOAA), since 2005, U.S. temperatures have actually gone down.
NOAA’s findings were based on a network of 114 temperature stations called U.S. Climate Reference Network (USCRN) spread out across the nation.
James Taylor wrote about NOAA’s findings in Forbes:
According to the USCRN temperature readings, U.S. temperatures are not rising at all – at least not since the network became operational 10 years ago. 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.
