A favorite claim of climate alarmists is that they adjust older temperatures upwards.
This certainly isn’t true for global land temperatures.
Newer versions of land temperatures keep getting adjusted further to cool the past.
There is little high quality temperature data outside the US.
The US data is massively adjusted to increase warming.
And the ocean data (like the land data) is largely fake.
Climate science is a farce. Junk science built on top of junk data.
