The breathless headlines have arrived : “Humans are causing climate change: It’s just been proven directly for the first time”
All they actually did was replot the same graph which the US Government has had out there for several years.
This graph directly contradicts what Tom Karl, longtime head of NOAA’s National Climatic Data Center said in 1989. He retired in 2017 just as President Trump took office.
“Analysis of warming since 1881 shows most of the increase in global temperature happened before 1919 — before the more re-cent sharp rise in the amount of carbon dioxide in the atmosphere, said Thomas Karl, of the National Oceanic and Atmospheric Administration’s National Climatic Data Center in Asheville, N.C. While global climate warmed overall since 1881, it actually cooled from 1921 to 1979, Karl said”
The warming from 1881-1919 has turned into cooling, and the cooling from 1921-1979 has turned into warming. When academics and government employees are willing to tamper with data – they can “prove” anything.
