"AMS Certified Meteorologist Mark Johnson Claims ‘Earth Hasn’t Warmed In 15 Years’"

Climate denier Mark Johnson, an AMS Certified Broadcast Meteorologist

Cleveland television meteorologist Mark Johnson, one of the anti-science weathermen exposed by the Forecast the Facts campaign, is now claiming that the “earth hasn’t warmed in 15 years.” Johnson, the chief meteorologist for ABC affiliate WEWS-TV in Cleveland, OH, is an American Meteorological Society Certified Broadcast Meteorologist.

Cribbing from a mendacious Daily Mail article, Johnson deliberately misrepresents the findings of the UK Meteorological Office that show the 2000s are the hottest decade on record:

Last week, the UK Met released its latest global temperature data to the world. It shows that the Earth has not warmed in 15 years. The warming ceased after the great super El Nino of 1998. The numbers are based on readings from more than 30,000 measuring stations around the planet. The data was quietly released last week without fanfare and it confirms that the rising trend in world temperatures ended in 1997.

In line with projections by climate scientists, the 2000s were significantly hotter than the 1990s, which were hotter than the 1980s, reflecting the steady rise in carbon dioxide emissions. This consistent increase in average temperature is partially masked by natural variability on short time spans. Johnson’s nonsensical claim rests on that deliberate misinterpretation of temperature data, as this infographic from Skeptical Science shows:

According to the American Meteorological Society, the Certified Broadcast Meteorologist program certifies that the “holder meets specific educational and experience criteria and has passed rigorous testing in their knowledge and communication of meteorology and related sciences needed to be an effective broadcast meteorologist.”

The AMS statement on climate change, last updated in 2007, concludes that “there is adequate evidence from observations and interpretations of climate simulations to conclude that the atmosphere, ocean, and land surface are warming; that humans have significantly contributed to this change; and that further climate change will continue to have important impacts on human societies, on economies, on ecosystems, and on wildlife through the 21st century and beyond.”

Update

This morning, the American Meteorological Society forwarded a debunking of the Daily Mail article to its members in its “News You Can Use” email.
