NASA GISS v4 shows more than 2C warming over land since 1880.

A different version of the same V4 graph also shows about 1.6C warming over land since 1880. This graph used to be linked to from their website, but I can no longer find any links. However the graph is still present on their website.

The red lines in both of the graphs above should be identical, but they aren’t. Here is an animation showing how they are altering the land data in the new graph vs. the old graph. They have increased recent temperatures by about 0.3C and cooled past temperatures by about the same amount.

The person in charge at NASA (Gavin Schmidt) has me blocked on Twitter, but Tom Nelson questioned him about this change. This is how he responded.

He does tweet in a colorful mask however.

But the data tampering story gets much worse. In 1974, the National Center for Atmospheric Research showed no net warming from 1870 to 1970, with the warmest decade being the 1940s, followed by a sharp cooling.

This cooling was confirmed in NOAA Magazine October, 1974

In 1978, the New York Times confirmed the cooling trend was continuing.

But NASA has since erased the post-1940 cooling.

In this Climategate email, climate scientists from different agencies discussed their desire to remove the 1940s warmth.

In 1981, NASA did show a 1940s blip followed by 0.3C cooling. They also showed a Medieval Warm Period and a Holocene Optimum.

Michael Mann later erased the Medieval Warm Period.

And the post 1940s cooling has since been erased by NASA.

As of the year 2000, NASA showed no net warming from 1870 to 1979, with 1878 being the warmest year.

But they now hide data before 1880, and show about 0.7C warming prior to 1980

The 1878 warmth is important because the Atlantic Multidecadal Oscillation peaked in 1878, and produced record warmth and global drought.

This didn’t suit the agenda of climate alarmists, so Michael Mann is now trying to erase the AMO.

The Biden administration forgot to provide any money for infrastructure in their first $2 trillion public theft earlier in the month, and now want to steal another $2 trillion to do useful things like expand Amtrak lines.

During the 20th century, people stopped using trains for cross country travel when other options became available – like plane travel which takes one-tenth as long, covers a much larger number of destinations, and is much cheaper. But Joe Biden wants to take people back to the 19th century and pack them on to trains, at the same time he wants people to social distance and avoid crowds.

The 1918-1919 flu pandemic infected 500 million people worldwide and killed 50 million. It was largely spread by train travel.

In Belen, N.Mex., local officials decided that only local returning residents could get off the Santa Fe trains stopping there. Out on the San Diego & Arizona Railroad, a dozen workers building the line through the Carrizo Gorge succumbed to the flu. A 2007 study in the journal Newfoundland & Labrador Studies concluded that passenger trains on the 906-mile narrow-gauge Newfoundland Railway contributed significantly to a deadly second wave of influenza that struck the island in late 1918 and into 1919.

Local leaders in Gunnison, Colo., on the Denver & Rio Grande narrow gauge, took an unusually tough stance. Motoring tourists were instructed to drive straight through town or submit to a quarantine, and passengers arriving on D&RG trains were obligated to go straight into a two-day quarantine.

Experts fear that Cheyenne may become ice-free sometime this summer if the current warming trend continues.

This week in 1913 had some horrific weather in the US. Floods, tornadoes, fires and a blizzard in Florida. Thousands dead and half a million people were left homeless.

Millions of people are risking everything to come to an America which Democrats are doing everything they can to destroy. Then they get locked in cages at the border.

Climate alarmists want people to believe that the weather was better when CO2 levels were lower, but history shows the exact opposite.

So far climate experts have erased the Medieval Warm period, Little Ice Age, 1940s warmth, and global cooling scare of the 1970s – and now they are working on erasing the Holocene Optimum and Atlantic Multidecadal Oscillation as well.
