Cooling or Warming: Which is it?

Whatever fits the template, I guess. From Gary Sutton, writing for Forbes:

Many of you are too young to remember, but in 1975 our government pushed "the coming ice age."

Random House dutifully printed "THE WEATHER CONSPIRACY … coming of the New Ice Age." This may be the only book ever written by 18 authors. All 18 lived just a short sled ride from Washington, D.C. Newsweek fell in line and did a cover issue warning us of global cooling on April 28, 1975. And The New York Times, Aug. 14, 1976, reported "many signs that Earth may be headed for another ice age."

In 1974, the National Science Board announced: "During the last 20 to 30 years, world temperature has fallen, irregularly at first but more sharply over the last decade. Judging from the record of the past interglacial ages, the present time of high temperatures should be drawing to an end…leading into the next ice age."...

While scientists march to the drumbeat of grant money, at least trees don't lie. Their growth rings show what's happened no matter which philosophy is in power. Tree rings show a mini ice age in Europe about the time Stradivarius crafted his violins. Chilled Alpine Spruce gave him tighter wood so the instruments sang with a new purity. But England had to give up the wines that the Romans cultivated while our globe cooled, switching from grapes to colder weather grains and learning to take comfort with beer, whisky and ales.

Yet many centuries earlier, during a global warming, Greenland was green. And so it stayed and was settled by Vikings for generations until global cooling came along. Leif Ericsson even made it to Newfoundland. His shallow draft boats, perfect for sailing and rowing up rivers to conquer villages, wouldn't have stood a chance against a baby iceberg.

Those sustained temperature swings, all before the evil economic benefits of oil consumption, suggest there are factors at work besides humans.
