Climatological Cassandras are becoming increasingly apprehensive, for the weather aberrations they are studying may be the harbinger of another ice age.
Telltale signs are everywhere —from the unexpected persistence and thickness of pack ice in the waters around Iceland to the southward migration of a warmth-loving creature like the armadillo from the Midwest. Since the 1940s the mean global temperature has dropped about 2.7° F. Although that figure is at best an estimate, it is supported by other convincing data. When Climatologist George J. Kukla of Columbia University's Lamont-Doherty Geological Observatory and his wife Helena analyzed satellite weather data for the Northern Hemisphere, they found that the area of the ice and snow cover had suddenly increased by 12% in 1971 and the increase has persisted ever since. Areas of Baffin Island in the Canadian Arctic, for example, were once totally free of any snow in summer; now they are covered year round.

There are many more older studies also showing this and the opposite.
But as of right now, the general consensus is that the earth is
in a warming period.
I think this is the problem: There will be individual studies or reviews of studies that will indicate the earth is cooling, the earth is warming, we cannot tell, the earth's temp. has generally stayed steady having up and down cycles.
But the general consensus is that the Earth is in a warming trend. This might change, as Science this big, is very complex, takes a lot of time, and can be interpreted in many ways depending on what one wants to looks at as significant. And of course political leanings.
And yes the press will take many findings or studies and blow them way out of proportion as to make for excitement... happens all the time in studies concerning certain food, drugs, epidemics...
'Eat raw pine needles, dont eat raw pine needles...'
So for our health nuts the following appear to be true as of now:
1. Smoking is linked to cancer, heart disease, and a few other things in most people.
2. Certain types of fats (saturated variety) increase the risk of heart and circulatory problems, strokes in most people.
3. High Fiber in the diet appears to lower the risk of colon cancer in most people.
We could go on.
ANd of course that person that smokes, eats only butter avoiding fiber at all costs will live to 100 getting killed in a car accident. Some will then conclude this is evidence that the 3 findings written above are wrong.
