Earth’s Temperature Hottest in 12,000 Years
Posted on Sep 25, 2006
Even scarier than the 12,000 figure: Earth is within one degree Celsius of the maximum temperature of the past million years.
... Hansen, who first warned of the danger of climate change decades ago, said that human-made greenhouse gases have become the dominant climate change factor.
The study said the recent warming has brought global temperature to a level within about one degree Celsius 1.8 degree Fahrenheit—of the maximum temperature of the past million years.
“If further global warming reaches 2 or 3 degrees Celsius, we will likely see changes that make Earth a different planet than the one we know. The last time it was that warm was in the middle Pliocene, about 3 million years ago, when sea level was estimated to have been about 25 meters (80 feet) higher than today,” Hansen said.
