CLEVELAND, Feb. 16 (A.A.P.).—
Dr. William S. Carlson, an Arctic expert, said to-night that the Polar icecaps were melting at an aston-
ishing and unexplained rate and were threatening to swamp seaports by raising the ocean levels.
Dr. Carlson said it would take hundreds of years for the melting to have much effect, but the rate in the last half century had been exceedingly rapid.
“The glaciers of Norway and Alaska are only half the size they were 50 years ago. The temperature around Spitsbergen has so modified that the sailing time has lengthened from three to eight months of the year,” he said.
