is going to explain the global cooling from 1940 to about 1970?
When will NASA expert James Hansen do it?

is astonishing to see that the majority of scientists have fully embraced
James Hansen’s ascertain he made 20 years ago, that men is responsible
for global warming. But until now he and IPCC fail to explain why it came
to three decade cooling period, although they know the facts since long.
back in 1981 the James Hansen’s team published their finding that,
overall, Earth’s average temperature rose by about 0.4°C for the period
from 1880 to 1978, but there was a global cooling from 1940-1970
that he considered subsequently as follows:
“I think the cooling that Earth experienced through the middle of
the twentieth century was due in part to natural variability,” he said.
“But there’s another factor made by humans which probably contributed,
and could even be the dominant cause: aerosols.” Meanwhile it is widely
claimed that a high concentration of sulphate aerosols in the atmosphere
may have had a cooling effect on the climate because they scatter light
from the Sun, reflecting its energy back out into space, by industrial
activities at the end of the second world war. The way Hansen and his
supporting colleagues handle the matter is insufficient for the following
sulphate aerosols relation towards the mid-century global cooling should
be checked against three facts, namely
cooling started with extreme winters in Northern Europe in winter
temperatures were low during the winter season, when the effect of
sulphate aerosols on sun ray was at the lowest, and thirdly
pre WWII industrial activities presumably had been much higher than
immediately after the end of WWII in 1945.
important for understanding the global cooling after 1940 until about 1970
is the impact of the seas and oceans. To understand the extreme cold
winters all over Northern Europe from 1939/40 to 1941/42, one has to
consider the impact of the North- and Baltic Sea, for the global cooling
one should take the North Atlantic and North Pacific into consideration,
and what men did do with them during WWII, as thoroughly explained at www.seaclimate.com.
