Real Climate Science

In 1988, NASA’s James Hansen predicted a huge increase in heat and drought.

If you liked last summer’s record temperatures, you’re going to love the 1990s, says James Hansen, the NASA scientist who, during congressional hearings on the Midwestern drought, linked greenhouse warming to the heat wave. Last summer was a preview of the average summer 10 years from now, and the hottest summers during the ’90s will be even hotter and drier than the one we just struggled through, he says.

If we do nothing to cut down on pumping carbon dioxide into the atmosphere, temperatures in 2050 will be 6 to 7 degrees higher than they are today. Washington, D.C., for instance, would go from its current 35 days a year over 90 degrees to 85 days a year.

He got all of his forecasts exactly backwards. The number of hot days in the DC area peaked in 1911, and have been declining ever since.

The number of hot days in the Midwest peaked in 1936, and have been declining ever since.

The last really dry year in the Midwest was 1988, and recent years have been record wet.

Hansen made temperature forecasts for three emissions scenarios.  Scenario A was increasing emission growth rates. Scenario B was decreasing emission growth rates. Scenario C was no emissions after the year 2000.

 

 

“We have considered cases ranging from business as usual, which is scenario A, to draconian emission cuts, scenario C, which would totally eliminate net trace gas growth by year 2000.”

So how did Hansen do? The graph below shows the five year mean of lower troposphere temperatures measured by satellite.

The next graph overlays the satellite lower troposphere temperatures in red, on Hansen’s 1988 forecasts – at the same scale and normalized to the early 1980’s. Lower troposphere temperatures have tracked Hansen’s zero emissions scenario.

The press quite predictably responded to Hansen’s massive failures, by declaring them to be correct.

James Hansen wishes he wasn’t so right about global warming

From May 21-31, 1922 – France had temperatures over 90 degrees every day. Paris was 95 degrees on May 24, 1922 – twenty-one degrees warmer than this year.

Look what just showed up in my Twitter recommendations.

Squaw Valley, California has had seventy-eight snow days since November 22 – totaling 715 inches of snow. They are thirteen inches behind the record year from two years ago, and may pass the record tomorrow. Average snowfall is 450 inches.

They will be skiing past July 4th this year.

Climate experts have been predicting the demise of Sierra Nevada snow, since the dawn of the global warming superstition.

This year they will be skiing in July, but in 1960 they barely had enough snow to hold the Winter Olympics in February.

But history is completely malleable for climate alarmists, so they simply rewrote the history of the 1960 Olympics.

Forty-six years ago this month, the world’s athletes frolicked in the snow at the 1960 Winter Olympics in Squaw Valley, Calif.

Climate alarmism is based on a superstition about carbon dioxide, which causes them to make baseless projections about the future, and having no morals or ethics – rewrite the past.
