One thing to emphasize more than that writeup did, is that in EA terms donating to such a lightly researched intervention (a few months work) is very likely dominated by donations to better research the area, finding higher expected value options and influencing others.
On the other hand, the point estimates in that report favored other charities like AMF over Cool Earth anyway, a conclusion strengthened by the OP critique (not that it excludes something else orders of magnitude better being found like unusual energy research, very effective political lobbying, geoengineering, etc; Open Philanthropy has made a few climate grants that look relatively leveraged).
And I agree with John Maxwell about it being oversold in some cases.
