Having just arrived in Johannesburg, President Clinton addressed a throng of young South Africans. He spoke of the great danger ahead. What was it? Was it the threat of AIDS, which is rampant throughout South Africa? Was it the threat of world terrorism? Was it the nation’s poverty and the need for young people to pursue education in order to escape poverty? None of these. He warned them about global warming! He said if trends continue, Africa would be under water because of the earth's ice melting.
When the global warming scare appeared in the 1980s, it was said if all the planet’s ice melted, ocean levels would rise 20 feet. But the world’s oceans have risen 350 feet in the last 18,000 years without any help from factories and automobiles burning fossil fuels and emitting carbon dioxide. The mean elevation of Africa is 1,900 feet, compared to 980 feet for Europe and 1,000 feet for Australia. So for Africa to be under water, Europe and Australia would have to be 900 feet under water.
Ocean levels have been rising ever since the end of the last Ice Age, about 12,000 years ago. For the last several centuries the rise has been 4 to 6 inches per century. And it would take a temperature rise of 55 degrees F. for a thousand years to melt the Antarctic ice cap.
Furthermore, the world’s largest ice masses, in Antarctica and Greenland, have been growing, not melting. The Greenland ice sheet has thickened by seven feet since it was first measured by laser altimetry from satellites in 1980.
For 95 percent of the past 100 million years the earth has been warmer than it is now. It was warmer 1,000, 3,000 and 6,000 years ago. We’re even below the average for the last 3,000 years.
So where is the “global warming”? It’s in the minds of the scaremongers and in invalid computer models that cannot be reconciled with actual temperature measurements, geologic records, and other physical evidence. For more on global warming, get my 3,000-word booklet on the subject.
