Worth noting is that Lemonic’s summary of the science is far from accurate. Here are the four points he dwells on:
“that the Earth is warming”
Yes.
“it’s largely due to us”
Partially is established, but not “largely”.
“it’s going to keep warming unless we do something”
Probably, but it depends on the answer to the previous question. Additionally, note that most people agree that even if we do “something”, it will almost certainly just delay whatever the effects are of a higher CO2 level. There are no serious proposals on the table that will cause CO2 to plateau.
“there’s a significant chance that the consequences will be disastrous.”
Hogwash. There’s little scientific basis for this claim. The majority of the effects of a higher temperature are very good for humanity.
