The NCAR graph above from the 1970s, showed 0.6F (0.33C) global cooling from 1945 to 1970, despite the fact that CO2 increased substantially during that period.

Fortunately, through careful analysis – Hansen has been able to reduce the amount of cooling from 1945-1970 by almost 40%.

That is a cool nature trick. But not the only one. The graph below was published by Hansen in 1987. Note that the 1940 anomaly was 0.25, but in the current graph it is only 0.1. Both graphs use the same baseline of 1951-1980.

Nature trick #2. Nice!

The image below shows the 1987 Hansen graph overlaid on the current one.

Note how temperatures were nearly identical in 1900, but in 1940 they were reduced by 0.15C. What a great way to get rid of that pesky global cooling problem!

No doubt it was all due to TOBS or homogenization or some other important temperature adjustment.

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