“The Mercury” Special Service
NEW YORK, Sun. — The world’s climate has become slowly warmer and there is a danger that the level of the oceans may be raised, causing serious inundations, as the result of melting of glaciers and polar ice-caps.
MR. I. TENNEHILL, chief of the reports and forecasts section for the United States Weather Bureau, says evidence of this weather change is becoming too impressive to be ignored.
Careful studies must be made of what is now happening.
Weathermen are unable to agree on the cause, but the rise in temperature has been going on for about 100 years.
In Boston (Washington) the average temperature was found to have risen between three and four degrees in that time.
Temperatures taken at 400 stations scattered around the world showed that in 18 out of 22 the year’s average temperatures were decidedly above normal.
Fish are reported to be moving farther north in oceans in the Northern Hemisphere.
Forests in Alaska are growing farther north.
Most of the world’s glaciers are melting faster.
In the State of Iowa the length of the growing season has increased by 20 days in the past 40 years.
