Scientist Behind Global Warming Theory Admits Data is False

Claims Al Gore took incomplete 'worst case scenario' data to promote climate change fear

Former NASA scientist James Hansen says the data used for Global Warming was false

The scientist who is widely regarded as the "Father of Global Warming" has admitted that the data used to promote his theory was false and manipulated to fit an agenda.

The former NASA scientist, James Hansen, was called on in the 1980s by Congress during a hearing on global warming organized by then-Congressman Al Gore to produce scientific models based on a number of different scenarios that could impact the planet.

According to Hansen, Gore took the data provided in a "worst-case scenario" and ran with it, rebranding it as "Global Warming."

The model, one of many provided to Congress by Hansen, titled Scenario B, left out significant factors meaning it didn't reflect real-world conditions.

A new study has compared real-world data to the original Scenario B model and found no correlation, to which Hansen responded saying he's "devastated" by the way his data has been used.

Real World data shows "no warming"

The dire climate prediction that was taken from Hansen's data model “significantly overstates the warming” observed in the real world since the 1980s, according to a new analysis.

Western Journal reports: Economist Ross McKitrick and climate scientist John Christy found observed warming trends match the low end of what Hansen told Congress during a hearing on global warming organized by then-Congressman Al Gore.

“Climate modelers will object that this explanation doesn’t fit the theories about climate change,” the two wrote.

“But those were the theories Hansen used, and they don’t fit the data.

"The bottom line is, climate science as encoded in the models is far from settled.”

Cato Institute climate scientists Patrick Michaels and Ryan Maue wrote that “surface temperatures are behaving as if we had capped 18 years ago the carbon-dioxide emissions responsible for the enhanced greenhouse effect.”

“But we didn’t. And it isn’t just Mr. Hansen who got it wrong,” Michaels and Maue wrote in The Wall Street Journal in June.

The WSJ op-ed set off a fierce debate over the accuracy of Hansen’s predictions.

Several media reports interviewing climate scientists claimed Hansen’s predictions — issued in 1988 — were pretty much correct.

Hansen’s dire global warming predictions turned 30 this year, sparking fawning media coverage of their accuracy.

The so-called “godfather” of global warming even told The Associated Press “I don’t want to be right in that sense.”

Some scientists moved the goalposts and argued even though Hansen’s temperature predictions were off, he got the radiative forcing from greenhouse gas emissions correct.

However, McKitrick and Christy’s analysis takes into account such objections, pointing out that Hansen’s prediction of carbon dioxide emissions was actually close to what was observed — there just wasn’t much warming.

It turns out Hansen’s worst-case scenario projection of global warming, known as Scenario B, only takes carbon dioxide emissions into account, but still showed too much warming, McKitrick and Christy wrote.

“What really matters is the trend over the forecast interval, and this is where the problems become visible,” McKitrick and Christy wrote.

Hansen’s conclusion, they wrote, “significantly overstates the warming.”
