Letter: Columnist exaggerates size of polar ice caps
To the Editor:
Don’t know where Mr. Hamilton gets his information about polar ice caps “..increasing to record proportions…” According to NASA and the Arctic Sea-Ice Monitor, the maximum extent of Arctic winter sea ice is at all-time lows, about half of what it was 1980, and while the Antarctic winter sea ice has increased in area, it is only by about 3 percent. More importantly, with regard to long-term effects on civilization, the thickness of the huge antarctic continental ice sheet is rapidly declining, thus putting more water into already rising oceans. The global effects of greenhouse gasses are real, and we humans put a lot of them into the atmosphere. It’s not smart to fool with Mother Nature.
