Well, as far as I know,. all the articles I have read say exactly the contrary, that the rate now is a lot faster than the one coming out from the ice age. Is because of that I ask your sources.

From [0]: > As the Earth moved out of ice ages over the past million years, the global temperature rose a total of 4 to 7 degrees Celsius over about 5,000 years. In the past century alone, the temperature has climbed 0.7 degrees Celsius, roughly ten times faster than the average rate of ice-age-recovery warming.

well, 20 seconds googling turned this up: http://www.nature.com/scitable/knowledge/library/abrupt-clim... Quote from the abstract: "One of the most surprising findings was that the shifts from cold stadials to the warm interstadial intervals occurred in a matter of decades, with air temperatures over Greenland rapidly warming 8 to 15°C"

DO cycles didn't changed the Earth global mean temperature, they are regional changes.

The "global mean temperature" is a statistical construct. It doesn't actually exist as a thing that can kill animals and plants. They only get to experience actual temperatures, and are clearly able to adapt to rapid changes in actual temperatures.
