warming accelerates rapidly with dire consequences for mankind and other creatures on Earth.
Exceeding the 400 parts per million level of worldwide atmospheric carbon dioxide later this

warming system; solar heating is sustained so there will be a build - up but whether that build - up is
accelerating or declining is the issue;

Indeed: — Absence of
accelerating warming — Existence of 30 years long cooling periods [1880 — 1910] then [1940 to 1970]-- Similitude of
warming rates (about +0,15 °C per
decade) during both [1910 — 1940] & [1970 to 2000] periods, whereas anthropogenic CO2 emissions have been multiplied by 5 here between, formally disproved AGW theory and IPCC claims.
seeking this answer is what used to be called «science»; trying to explain why the prediction of continued
accelerating global
warming from the 52 % increase in CO2 emissions from fossil fuels since Hansen predicted this in 1988 has failed to materialize and trying to explain why the Earth has experienced no global
warming for over a
decade in spite of the 26 % increase in CO2 emissions from fossil fuels is what is funny
