Thirty-nine years ago today, experts reported a northern hemisphere cooling trend of 0.1C to 0.2C per decade from 1950 to 1975.
The report, prepared by German, Japanese and American specialists, appears in the Dec. 15 issue of Nature, the British journal. The findings indicate that from 1950 to 1975 the cooling, per decade, of most climate indexes in the Northern Hemisphere was from 0.1 to 0.2 degrees Celsius, roughly 0.2 to 0.4 degrees Fahrenheit.
NASA used to show this cooling trend, but has now made it almost entirely disappear.

The winter of 1978 was the coldest on record in the US, yet this date in 1978 was much warmer than today’s temperatures.
