CO2 Levels Now The Highest in 15 Million Years

Great.

A new and accurate technique has found that current CO2 levels are higher now than at any time in the past 15 million years.

"The last time carbon dioxide levels were apparently as high as they are today — and were sustained at those levels — global temperatures were 5 to 10 degrees Fahrenheit higher than they are today, the sea level was approximately 75 to 120 feet higher than today, there was no permanent sea ice cap in the Arctic and very little ice on Antarctica and Greenland," said the paper's lead author, Aradhna Tripati, a UCLA assistant professor in the department of Earth and space sciences and the department of atmospheric and oceanic sciences.

Think about that for a moment: even if we eliminate 100% of all carbon emissions today, worldwide ... the existing CO2 in the air will still take us all to a planet where no human being has ever lived.
