Sorry, made a mistake, the emissions / increase / temperature curve I have plotted is based on the HadSST temperature data, not from UAH, as these start only after 1979...

Indeed, a portion of that small linear trend difference might be due to human CO2 emissions; or, then again, it might be due to the vast urbanization effect over the last 60 + years; or due to the large deforestation that's taken place; or, maybe it's entirely due to the serial fabrication of global warming by the world's climate agencies; or it's even possible that the post-1950 warming was entirely a natural phenomenon - the same as the prior 64 - year period experience.
