GISS 1997 : 80% Of Northern Hemisphere Warming Occurred Prior To 1940

In 1997, GISS showed 0.8ºC warming in the Northern Hemisphere from 1885 to 1940 – when CO2 was 310 PPM. Over the next 45 years, only 0.2ºC additional warming has occurred.

    why would temps fall from 1940-1980 when CO2 was rising, assuming man is the primary cause of global warming?
