MAR: “(Hansen) began to insist that we would see 5m of SLR by 2100.”

NK: Hansen never insisted such a thing. Please stop verbaling his work, putting words in his mouth. and presenting false characterizations of his papers, articles and his actual science arguments.
eg
“Alley (2010) reviewed projections of sea level rise by 2100, showing several clustered around 1 m and
one outlier at 5 m, all of these approximated as linear in his graph. The 5 m estimate is what Hansen (2007)
suggested was possible under IPCC’s BAU climate forcing.”

Ice Melt speaks for itself. Please stop misrepresenting it as well.

I suggest you should be forced to provide supporting quotes/evidence for all your accusations against others – against Hansen and people who post comments here because you appear to be habitually wrong.

Then there is MAR says : “Hansen’s ‘reason to be fearful,” (completely made up rhetoric by MAR) and “the seventh being Hansen et al’s argument that geo-engineering is a “required action.” “

Again this social media rhetoric by MAR at is a grossly false distortion, a misrepresentation, bordering imho on outright lying what Hansen actually said: which was in fact>
Abstract – “The enormity of consequences demands a return to Holocene-level global temperature. Required actions include: (1) a global increasing price on GHG emissions accompanied by development of abundant, affordable, dispatchable clean energy, (2) East-West cooperation in a way that accommodates developing world needs, and (3) intervention with Earth’s radiation imbalance to phase down today’s massive human-made ‘geo-transformation’ of Earth’s climate.” ,

That is the ONLY place in the entire Research Paper that Hansen uses the phrase “Required actions” – it is a cherry pick by MAR that distorts Hansen’s actual recommendations for action – being INTERVENTION and not Geoengineering!

MAR then proceeds to rephrase :”The Michael Mann comments “ in his November 1, 2023 artilce;

NK: To whit Hansen’s replies forcefully to all with this in March 2024:
“The scientists reject, without any evidence to the contrary, the evidence we presented that IPCC’s best estimates for climate sensitivity and human-made aerosol forcing are substantial underestimates. They rule out, without evidence, our suggestion that decreases of aerosols, especially those produced by ships, are a significant climate forcing that is causing global warming acceleration.” See Page 3 –

MAR: claims Hansen did not provide ” a point-by-point analysis. “

NK: I put it to readers that M Mann in his artcile DID NOT provide ” a point-by-point analysis” nor REFUTATION of the major Points in the Piplenie paper – he skipped them, and offered irreleavnt or superceded information.

M Mann (and others too) say a lot. But this article and misc social media comments do not amount to a peer reviewed paper, nor genuine scientific evidence / data, nor a valid scientific argument against Hansen et al 2023.

Nor does what M Mann say equate to an IPCC Consensus that his arguments are valid or undermine what Hansen et al 2023 have concluded – which to Mann has argued is the gold standard of approval and scientific agreement.

IPCC represents the consensus. Individual articles don’t. Until there’s a major assessment (NAS or IPCC) saying otherwise, the claim of a sharp decrease in global aerosol forcing past 4 years must be considered an extraordinary claim lacking evidence. I’m done w/ this now, ok?

NOW, people may choose to believe Hansen, or to believe Mann, and many others who declare Hansen;s work invalid, flawed, or ludicrous … but that is a process of BELIEF not science, nor the scientific method.

This will not stop people trying to have it both ways anyway …. Hansen has been open and provided personal and professional reasons for everything he does and has not done. Believe it or not, or remember what he has said or not does not change Hansen’s position,

Kind Regards …
