Can you (or anyone else) point out (provide a link to) a single paper that has described the great net harms that humanity will incur as a result of AGW, that is believed to be an unbiased and valid scientific analysis?
Believed by whom?
There are many, many papers that estimate the harmful impacts expected as a result of global warming.
I’m sure you can find them on your own.
When you do you are welcome to raise any points about them you think are important.
But being accepted by “skeptics” as valid and unbiased is not necessary for science to go on. In fact, it’d say being a paper praised by “skeptics” as valid and unbiased is strongly associated with the quality of being a streaming pile of crap.
