In 1997, GISS showed 0.8ºC warming in the Northern Hemisphere from 1885 to 1940 – when CO2 was 310 PPM. Over the next 45 years, only 0.2ºC additional warming has occurred.

No wonder Hansen decided to rewrite history. There is no CO2 footprint in the actual temperature record.
Venus is a perfect example of the greenhouse effect. Sunlight passes through the clouds in the form of radiation. The sunlight is absorbed by the surface causing it to heat. The cloud layer, which is opaque, traps the heat causing the greenhouse effect. Because of the heavy cloud layer, only about 2% of the sunlight reaches the surface of Venus. Imagine what it would be like if 100% of the light reached the surface.
A place which receives almost no light and is very hot, is obviously not being heated by the greenhouse effect. Venusian nights last for months, there is no incoming SW radiation, yet the temperature never cools down at all. Only a complete moron would blame the heat on Venus on “the greenhouse effect.”
Enter Sagan and Hansen.
In 1997, GISS showed that the Southern Hemisphere warmed from 1882 to 1910. Now they show the exact opposite.

Also in 1997, Hansen said he knew temperatures accurately within 0.07 degrees.
The annual-mean global-mean temperature anomaly in recent decades is estimated to have a two-sigma uncertainty of about 0.07°C due to incomplete spatial coverage of stations. Thus the relative rank of different years is uncertain for years whose temperatures differ by less than that amount.
So was he lying then, or is he lying now?
Omaha has never had a summer with less than 55 days over 80 degrees.
If he meant to say 90 degree days, they have dropped dramatically since 1895 and are now below 30/year for the first time. Hansen has absolutely no clue what he is talking about.
America’s newest, most expensive coal-fired power plantis hailed as one of the cleanest on the planet, thanks to government-backed technology that removes carbon dioxide and keeps it out of the atmosphere.

Making electricity prices skyrocket, just as he promised! We can all breathe easier knowing that an undetectable amount of an essential, invisible, harmless, odorless gas has been removed – at great expense.
a major puzzle in the global warming debate: why computer models have shown more significant warming than actual temperature data.
Fourteen years making the same excuse, and these geniuses still haven’t fixed the models.
In 1998, Hansen thought he was on to something.
It turned out that he was wrong. Temperatures went horizontal after 1998.
Most normal people would be able to figure out that they were wrong after 15 years, but Hansen simply ramped up the BS – and the data tampering.
According to GISS 1997 global data, temperatures responded to increases in CO2 much more rapidly below 310 PPM.

The web archive never forgets.
In 1997, GISS showed that about three-fourths of global warming occurred prior to 1940. In other words, global warming started before CO2 started rising significantly, and recent global warming coincided exactly with the PDO shift in 1976.

But it is worse than it seems. It turns out that 1940 to 1970 global cooling was real, before they deep-sixed it.
The next graph shows how GISS has altered the data since 1997.

Now we know why GISS doesn’t keep their old data around. It doesn’t support global warming theory.
