Yes, we need to reduce CO2 emissions over the course of the 21st century." Judith Curry, Ph.D., climate scientist, from her website:
My response, below, is a slightly edited version of a comment I just sent to her blog, which may show up after moderation, or maybe not. That website does not publish all comments. My comments there show up under the moniker, The Cliff Claven of Finance (it's a long story):
THAT STATEMENT IS COMPLETELY FALSE.
More CO2 is a benefit for humans, animals, and ESPECIALLY C3 plants that humans and animals eat.
NO harm has been done by the almost +50% increase of CO2 estimated since 1850
No harm was done by the global warming from 1975 to 2015.
In fact, people in colder climates have warmer winter nights now compared with the 1970s, which is great news for them. Antarctica is not melting, because CO2 does not have a warming effect with the temperature inversion over Antarctica.
If there was any harm done by the global warming since 1975, and manmade CO2 enrichment since about 1850, then such harm MUST be described before you make the FALSE claim: "Yes, we need to reduce CO2 emissions over the course of the 21st century."
Humans have no ability to make long term climate predictions. Even merely extrapolating the next 30 to 50 years of climate based on the past 30 to 50 years of climate, does not work.
Sorry, but you should not be taken seriously as a scientist, if you really believe the long-term climate can be predicted, the future climate can only get worse, which must be your house of cards foundation for the false statement:"Yes, we need to reduce CO2 emissions over the course of the 21st century.".
I hope this comment shows up and lasts for at least a few hours. I have had too many comments in the past that never showed up, or they showed up, and then disappeared after a delay.
Real scientists should be very skeptical. I am not a scientist, but I am properly skeptical. You are not skeptical enough about an energy transition that IS NOT NEEDED.
The US electric grids are NOT broken, and do not need to be fixed, at great expense, with the result of less reliable electricity. That is an insane waste of money.
