The National Academy of Sciences asks “When could scientists have first known about climate change?”
Fifty years ago they answered the question.
“The climates of the earth have always been changing, and they will doubtless continue to do so in the future. How large these future changes will be, and where and how rapidly they will occur, we do not know.”
NATIONAL ACADEMY OF SCIENCES, 1975
Back then they knew that they don’t know.
Now they pretend that they do
though none of their many models can predict the future nor the past(before adjustment).
Maybe the total failures of their ice age and warming predictions encouraged them to believe that they are supercompetent.
Climate Science made probably the biggest progress of any science in history.
They went from no being able to read thermometers a hundred yeare ago
to predicting an ice age to predict a warming
to reading climate fingerprints within only a century.
