NASA-GISS is the biggest manipulator of data that every existed.
The climate fraudsters are all over the Internet today claiming that they are adjusting raw temperatures in a way which reduces warming. Let’s check that claim out.
The US has the only decent long term temperature record covering a large area of this planet. Temperatures here are being massively adjusted to increase warming, the exact opposite of what the fraudsters claim. Older temperatures are being adjusted down, and newer temperatures are being adjusted up.
The data tampering accounts for almost the entire claimed warming trend in the US.
