Not long ago the world experienced a ‘global cooling’, starting with thee extreme winters in Europe (1939/40 to 1941/42), which
continued across the Northern Hemisphere (1940 to mid-1970th). As science failed to analyze, understand and explain the issue, this site discusses the thesis that human activities were the likely cause. A thorough understanding of the phase of cooling several decades ago would have reduced any superficial talking about the reason and impact of the ‘cold blob’ currently active in the North Atlantic.
Seven decades after WWII the entire world is glowing red [Fig. 1], only a tiny blue eye defies the global picture. The alert is high, the number of questions higher, and suggestions about the possible cause the highest. Per se that is not necessarily bad. The matter is more serious as the size indicates, as this blob of unusually chilly water seems like semi-permanent residence in the North Atlantic Ocean; which is “a marine cold wave that won’t go away”(1) Northern Hemisphere air temperature are likely to decrease over
an unknown period of time. And how is science handling the issue? There is little explained comprehensible. There is little that can be taken take seriously. Most is mere gabbling. Why?
As the entire ocean, also the North Atlantic is a huge water body, very deep, very saline, and very, very cold. The overall mean temperature is about 4 ° Celsius, in the North Atlantic due to the Gulf Current by 1-2° slightly higher, as indicated in Fig. 2, which does not show currents, gyres and eddies. Any cold blob analysis has to discuss it on this basis and much more data from the sea bottom to the sea surface. Instead, curious facts and assumptions are named for drawing conclusions on causality. The result is gabbling, and presumably far away from reality, and a
Another theory as to why the ocean’s current caused the anomaly is according Gavin Schmidt, the director of the NASA Goddard Institute for Space Studies in New York (4), that melting ice from Greenland and the Arctic flowed into the Atlantic Ocean’s current and essentially drowned out the warmer water rising from the South Atlantic.
Other researchers claim a warmer North Atlantic in the upper 700 meters, the wind, “oceanic heat wave”, or “natural variability”. Not many of them seem to pay attention to the different heat capacity: ocean vs atmosphere; the latter with only about 0.001 percent of the total Earth’s water volume, respectively energy content (Fig. 3). Much more ocean data and records are needed. Not necessarily 1’000-times more as available for the atmosphere, but not 100-times less. That is a matter science has to communicate, before assuming casual correlations, and risking gabbling.
“Global cooling” from 1940 to the 1970th [Fig. 4] is still on offer for a better understanding of anthropogenic climate change, and which impact human activities at sea may have had in the past and present.
