@NigelStarr1 @Barba_Phil51323 @AssoClimatoReal Vous êtes au courant que le GIEC ne fait pas de recherche, mais une revue et une synthèse de la littérature pertinente? Par exemple : https://t.co/ie4QbXypik Il y en a d'autres : https://t.co/gnyWCVNExn
@JohanVanbrabant @simondonner That kind of reasoning doesn’t work in the real world. Most of our carbon pollution is still in the atmosphere. https://t.co/3b9kSc32ox

@lexhoogduin @TinusPulles @GerritHiemstra Dat is uitgebreid onderzocht. Héél langzaam wordt het extra CO2 uit de dampkring gehaald o.a. door sedimentering. De laatste ca. 20% van 'ons' extra CO2 is pas ca. 400.000 jaar uit de dampkring. Zie o.a. prof. Ar

@VincentJappi @tan123 The 'long tail' of anthropogenic CO2 injection into the atmosphere is due to the fact that geological processes which finally remove the carbon from the climate system take many millennia to restore equilibrium. https://t.co/24zZcxVJf
Old news not much touched on these days because 'settled', obvious. See eg below, but note *percent of emissions*. Atmospheric increase we observe is only ~half emissions due to immediate uptake by ocean+biosphere, so need to double these. https://t.co/
@miwachan_info @YohYasuda 私が知っていたことは、安井至先生がブログ https://t.co/Z3TzfP9d7d 等で紹介されていたもので、元ネタはCO2半減期が 、 https://t.co/drk0EsGaay Tipping Elementsが、 https://t.co/znjB8U9Oq6 でした。前者はその後どうなったかな?と。 ご紹介いただいたシアン氏の論文をまず読んでみます。
つうか、海洋でのCO2半減期が1,000年以上だったら、せっかく大気から回収してもCH4ですぐまた焚いていたら、使い回しているだけで、450ppmとかは2100年までに少なくとも「ちーとも減らん」がな...(´・ω・`) "The millennial atmospheric lifetime of anthropogenic CO2" https://t.co/drk0EsGaay
