Have you heard the latest? We're
at almost at the warmest temperatures in a million years!
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.Yes -- and the cause? Correct! Us human types
"This evidence implies that we are getting close to dangerous levels of human-made pollution," Hansen said in a statement.Yet he goes on to say this little bit of information:
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.
"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.So, who caused the changes last time? Thats the million dollar question, right? I guess those Pliocenes actually had athropogenic global
