Claim: Earth Hasn't Warmed for Last 58 Years

NOAA suppressing data.

Tony Heller at Real Science blog is countering the National Oceanic and Atmospheric Administration's claim that 2015 was the "hottest year ever" and accusing them of suppressing data that would show that the Earth in fact hasn't experienced any warming over the last 58 years.

Radiosonde data that was referenced during NOAA's recent press briefing on climate change showed only the last 37 years in the graph, according to Heller. And he gives a clue as to why:

The earlier data showed as much pre-1979 cooling as the post-1979 warming.

So, Heller explained that he combined the two graphs at the same scale and found that the earth's atmosphere "has not warmed at all since the late 1950s."

"The omission of this data from the NOAA report, is just their latest attempt to defraud the public," Heller states. "NOAA’s best data shows no warming for 60 years."

"But it gets worse," he adds. "The graph in the NOAA report shows about 0.5C warming from 1979 to 2010, but their original published data shows little warming during that period."

Other charts included on the Real Science blog shows how much the NOAA has altered temperature data to show an increase in temps and therefore "prove" global warming. But Heller has called them out:

Due to Urban Heat Island Effects, the NOAA surface data shows nearly one degree warming from 1979 to 2010, but their original radiosonde data showed little warming during that time. Global warming theory is based on troposphere warming, which is why the radiosonde data should be used by modelers – instead of the UHI contaminated surface data.

NOAA's efforts are keeping in step with President Obama's continued talking point that the last few years have been the hottest on record. It's no wonder why they have to obscure the data.
