This MIT article admits that Mann-made global warming is BS, then goes on to spin even more BS to make it sound like that isn’t want they are really saying.
This is the only sentence in the article which has any substance.
Will we actually ever see the longwave trapping effects of CO2 in future observations? I think the answer is probably no.”
They can’t leave it at that, so they go on with paragraphs of BS to make it sound like they are saying something completely different. This one is the punch line.
As longwave radiation gets trapped by CO2, the Earth starts to warm, impacting various parts of the climate system. Sea ice and snow cover melt, turning brilliant white reflectors of sunlight into darker spots.
These geniuses just contradicted their entire thesis about longwave radiation (not) being trapped by CO2. Not to mention the fact that the amount of sea ice on Earth is above normal, and that winter snow extent has been increasing and is at record highs.
The takeaway from the article is that the authors believe that Mann-made global warming is nonsense, but can’t say it for political reasons.
