The year was 1974 and NOAA's headline was "
NOAA 1974 - Global Cooling Will Starve the World
""The poorest nations, already beset by man-made disasters, have been threatened by a natural one: the possibility of climatic changes ...perhaps throughout the world. The implications for global food and population policies are ominous..." - NOAA, 1974
Most forecasts of worldwide food production have been based on the assumption that global weather will stay about the same as it has been in the recent past. But it has already begun to change.
In the Sahelian zone of Africa south of the Sahara, the countries of Chad, The Gambia, Mali, Mauritania, Niger, Senegal, and Upper Volta are enduring a drought that in some areas has been going on for more than six years now, following some 40 previous years of abundant monsoon rainfall. And the drought is spreading—eastward into Ehtiopia and southward into Dahomey, Egypt, Guinea, Kenya, Nigeria, Somalia, Tanzania, and Zaire.
Many climatologists have associated this drought and other recent weather anomalies with a global cooling trend and changes in atmospheric circulation which, if prolonged, pose serious threats to major food-producing regions of the world.
Annual average temperatures over the Northern Hemisphere increased rather dramatically from about 1890 through 1940, but have been falling ever since. The total change has averaged about one-half degree Centigrade, with the greatest cooling in higher latitudes. A drop of only one or two degrees Centigrade in the annual average temperature at higher latitudes can shorten the growing season so that some crops have to be abandoned. [...]
...the average growing season in England is already two weeks shorter than it was before 1950. Since the late 1950's, Iceland's hay crop yield has dropped about 25 percent, while pack ice in waters around Iceland and Greenland ports is becoming the hazard to navigation it was during the 17th and 18th centuries. [...]
Some climatologists think that if the current cooling trend continues, drought will occur more frequently in India—indeed, through much of Asia, the world's hungriest continent. [...]
Some climatologists think that the present cooling trend may be the start of a slide into another period of major glaciation, popularly called an "ice age."
This is consistent with the documented media hysteria of the 1970s about global cooling and demonstrates, contrary to alarmist arguments - that many climatologists did agree with the media's representation of a coming ice age apocalypse. 
I got this in a Email from www.populartechnology.net... Technologynet+%28Popular+Technology.net%29

Many other scientists disagree. J. Murray Mitchell Jr., of the Environmental Data Service, a world authority on climatic change, comments. "We observe these trends, and we know they are real. But we can't find the central tendency, we just don't know how long they will last." Mitchell himself suspects that the present cooling trend will reverse itself rather soon.

Yes I mentioned that I got it off of a website and linked it . I also linked to the NOAA PDF .that was mentioning the cooling trend . I am not sure what the trend is as of late but last I checked it was a trend of 18 years ...I shall see if I can find out what is happening now . Trends can fluctuate it seems as a metric because of the complicated way they look at it .
Dr. Reid Bryson, Director of the University of Wisconsin's Institute for Environmental Studies, thinks that the relatively warm period from about 1890 to 1940 was only a brief intermission in the "Little Ice Age," a period of worldwide expansion of snow cover.
that is true then we can expect a few years of cooling coming our way ..time will tell I guess .
The upshot, said Christy, is that while there is a clear warming signal in the satellite temperature data, caution should be used when trying to extrapolate long-term conclusions about climate change based on months and years whose temperatures are obvious outliers driven by El Niño warming events. The 2015-16 El Niño appears to be fading fast. Sea surface temperatures in the east central Pacific have fallen below norms, and a La Niña Pacific Ocean cooling event may be on its way. It is a tiny sample, but 3-year La Niña cooling followed immediately after strong El Niño events in 1972-73 and 1997-98. “We should expect continued, but erratic cooling through the end of the year,” Christy said. “In comparing the current El Niño to the major 1997-98 event, we see that globally the last two months have fallen below the values seen in 1998. The ‘race’ for the hottest year is getting closer. (See attached graph.) Through May, 2016 (+0.67 C warmer than seasonal norms) is leading 1998 (+0.60 C). Annual anomalies, however, are accurate to only ± 0.1 C, so the two years are really in a statistical tie.” Compared to seasonal norms, the warmest average temperature anomaly on Earth in May was just off the western coast of the Antarctic Peninsula in the Bellingshausen Sea. May temperatures there averaged 4.10 C (about 7.38 degrees F) warmer than seasonal norms. Compared to seasonal norms, the coolest average temperature on Earth in May was near South Georgia and the South Sandwich Islands in the South Atlantic, where the average May 2016 temperature was 3.08 C (about 5.54 degrees F) cooler than normal for May.
Thanks for the links .If the past has any bearing on the future then the temps will drop .
We manufacture warmer cloths because we don't like the cold .We buy air-conditioners because we don't like the heat .We put more insulation in our homes to combat the heat and the cold . We are living longer and are probably more comfortable then Humans were 200 years ago ....life sucks eh ?
That really screws up the natural order of things. Humans have gotten really good at doing that.
OK...I see that it does show a logarithmic effect but the formulas for a "Simplified expression Radiative forcing" don't seem to account for variables other than changes in concentration. I guess that would be part of the "simplification." Would you agree?
For more info, see IPCC 6.3.4 "Total Well-Mixed Greenhouse Gas Forcing Estimate", that is where the incremental effects are calculated.
