The National Oceanic and Atmospheric Administration (NOAA) declared 2015 is the second hottest year on record for the contiguous U.S., with the average annual temperature 2.4 degrees Fahrenheit above the 20th century average.
NOAA says the U.S. averaged 54.4 degrees Fahrenheit for the year, coming in behind 2012 in terms of record-high temperatures. 2012 averaged 55.3 degrees Fahrenheit. Liberal news outlets and politicos are using it as evidence human activities are heating the planet.

There’s just one problem: the U.S. temperature record may be contaminated with bad data, according to a recent study by climate experts.
Most of the more than 1,200 weather stations used by NOAA to calculate the average temperature have been “compromised by encroachment of artificial surfaces like concrete, asphalt, and heat sources like air conditioner exhausts,” according to Anthony Watts, a seasoned meteorologist and lead author of a recent study examining the integrity of thermometer data.
Watts and his fellow authors found these “compromised” weather stations run hotter than the 210 “unperturbed” stations use by NOAA. What’s problematic is that NOAA adjusts temperature readings from well-sited stations upwards to be in line with readings from “compromised” stations — this makes it look like the U.S. is warming faster than it actually is.

“This study demonstrates conclusively that this issue affects temperature trend and that NOAA’s methods are not correcting for this problem, resulting in an inflated temperature trend. It suggests that the trend for U.S. temperature will need to be corrected.” Watts says.
Despite the potential problems with NOAA’s weather station network, the agency and others have predicted 2015 will be the hottest year on record, “The state of the global climate in 2015 will make history as for a number of reasons,” World Meteorological Organization Secretary-General Michel Jarraud says in a statement.
