The recent release of the Berkeley Earth Surface Temperature (BEST) study, which showed a worldwide temperature increase of about 1°C since 1950, was heralded by many as proof of global warming. Some skeptics, however, noted that the BEST data also showed that temperatures had remained unchanged for the past decade, suggesting that any warming trend had ended around the turn of the century.
Meteorologist and climate-science blogger Anthony Watts has gone those skeptics one better. Having analyzed U.S. temperature data from the National Oceanic and Atmospheric Administration’s National Climatic Data Center, Watts declared in a column for the Daily Caller: “The trend for the continental United States for the past 10 years is not flat, but cooling.”
Watts broke the data down by winter, summer, and annual temperatures in each of nine designated regions in the continental United States. For wintertime he found that “every region … has a negative temperature trend for the last decade,” ranging from -1.3°F in the Western Region (California and Nevada) to -8.74°F in the East North Central Region (Minnesota, Iowa, Wisconsin, and Michigan).
