A Japanese meteorologist doesn’t have a new theme, altogether, on the extent of pollutant particles in the air, but his analysis is worthy of being added to the worldwide evaluation of the subject itself.

Dr. Tadashi Yano of Osaka says, in effect, that the ever-increasing number of pollutant particles in the air is slowly, but surely, choking off the earth’s incoming sunlight, lowering temperatures worldwide and threatening to plunge the planet into another Ice Age.

Aerosol particles, as generated when oil and coal are burned, are increasing annually and now are dense enough to block some of the sun’s rays, he says.

Then he provides some supporting data. From 1880 to 1940, for instance, the average global temperature rose 1.1 degrees Fahrenheit, but since 1940 (when the number of airborne particles began to increase rapidly), the temperature has fallen .9 degrees Fahrenheit. If pollution continues to increase at its present rate, be summarizes, the particles will become nuclei for moisture that could form a band of clouds even more effectively shielding out the sun.

As many scientists already have pointed out, It wouldn’t take much to trigger another Ice Age. Since polar &glaciers melt some at their edges each summer and freeze over again in the fall, any temperature drop large enough to upset the delicate balance could spell trouble. There are those who believe that if the amount of solar energy were cut by as little as 1.6 per cent the entire globe would be engulfed in ice.
