we had an ice age right now? Less than 20,000 years ago, half of the U.S. was covered with ice and Canada was one big ice cube. 20,000 years is less than a second when compared with the age of the earth.
An ice age would cause billions of people to starve to death.
The grand canyon was formed from melting water from thawing ice ages. Over 20 million years, melting water carved out huge sections of land in Arizona.
NASA has said that great temperature changes are normal. Just 10,000 years ago, the earth warmed up extremely in less than 20 years. There were not many people around at that time.
NASA:
"Rapid changes between ice ages and warm periods (called interglacials) are recorded in the Greenland ice sheet. Occurring over ONE OR TWO DECADES, the warming of the Earth at the end of the last ice age "
