When did global warming become a concern to scientists?

Answer 1

I believe it was in the early 1970's as the deepfreeze that the world had been in since 1948 began to go away. Of course, if cold goes away, you are left with . . . YES! warmer weather!

The early scientists, Mann et al, performed experiments and made conclusions about the climate. Most people do not realize that when other scientists tried to duplicate Mann's work, they could not, and accused him of making too many conclusions that were not based on hard evidence.

This did not stop Al Gore, though. He made an issue of it, as politicians often do, probably to 1) Take people's minds off the bad deeds of his party, and 2) Getting more votes from environmentalists.

Once the climate change issue started rolling, scientists soon found out that they could get rich on grant money given out to study climate change. When some 31,000 scientists signed a document in Oregon a few years ago, saying that they did not think warming was a real issue: a hoax, if you will, the liberal thinkers completely blew it off as meaningless.

Yet, when 52 scientists had previously testified to the United Nations that global warming was a real phenomenon, the liberals took this as proof.

So, that would be 52 Yes votes, and 31,000 No votes. The Yesses won. ???

Answer 2

Scientists began expressing concerns about global warming in the late 20th century, with a growing body of evidence pointing to human activities as a significant contributing factor to rising global temperatures. This led to increased research, awareness, and efforts to address the issue on a global scale.
