Real Climate Science

Please ignore the fact that most of the Northern Hemisphere and Antarctica are running far below normal.

In 1981, James Hansen of NASA published these graphs of  surface temperatures. Note that northern latitudes and global both showed 1940 as warmest, with a sharp global cooling to the early 1970’s.

But the current NASA graphs don’t look anything like that. Global surface temperatures no longer show any cooling from 1940 to 1970.

Data.GISS: GISS Surface Temperature Analysis: Analysis Graphs and Plots

I overlaid current GISS global surface temperatures (red) on Hansen’s 1981 version. Hansen massively cooled his own pre-1980 data, and added a huge spike in 1979.

Also note that Hansen has nearly wiped out all of his own 1940-1970 cooling.

Now let’s look at just the 24N-90N temperatures, current data in red. Hansen has knocked 0.2C off his own 1940 temperatures. The shape of the data is nearly identical, but NASA now adds an increasingly larger cheat factor of cooling to progressively older data.

Everyone agreed about the post-1940’s global cooling at the time, including Hansen. But Hansen and now Gavin have deleted it from the temperature record.

Leading climate scientists discussed with each other how to get rid of the 1940’s warmth, which might have impacted their ability to extort taxpayer money.

Phil,

Here are some speculations on correcting SSTs to partly
explain the 1940s warming blip.

If you look at the attached plot you will see that the
land also shows the 1940s blip (as I'm sure you know).

So, if we could reduce the ocean blip by, say, 0.15 degC,
then this would be significant for the global mean -- but
we'd still have to explain the land blip.

If the present refuses to get warmer, then the past must get much cooler.

The heat around Katherine Hayhoe’s house is just too much for a bear to bear.

In 1981, Hansen predicted this CO2 warming. This is from his conservative days, which Gavin’s FakeClimate likes to brag about.

I overlaid GISS 1997 global temperatures on top of Hansen’s 1981 forecasts for CO2 warming. It shows that most warming occurred before CO2 warming “kicked in.”

Warming by 1940 was 5X CO2 warming.. A special thanks James Hansen for proving that natural variability overwhelms CO2.

Urgent request for all climate experts at CU/CSU/NOAA. Please turn off your fossil fuel powered heating this morning, and prevent these outbreaks of Mann-made global warming from recurring.
