Global warming
One of the causes of global warming is being ignored.
Scientist say the last Ice Age ended 12,500 years ago and there was three miles of ice covering Canada.
Two miles equals 126,720 inches.
Divide 126,720 inches by 12,500 years and we have an average of 10.1376 inches of ice melting per year.
This thaw would have been slower at the start as the sun’s rays would have been reflected back from the huge ice caps at the north and south poles. B
