d/dt ( GISS LOTI ) global average

Karlisation of the SST record has removed the acceleration which was supposed to be the fingerprint of AGW.

The rate of warming has been essentially constant since 1975 ie ZERO acceleration for the last FORTY years. That is greater than the generally accepted 30y definition of “climate” as opposed to weather.

Atmospheric CO2 is still increasing at a steady 2 ppmv per year constantly increasing the “forcing” and this is claimed to be the “dominant” cause of warming by the IPCC.

GISS LOTI data is totally incompatible with that conclusion.
