Co2 has increased dramatically and there has been no warming for the past 15 years.
The global warming models will not reproduce the current weather when using the data of the past 30 years.
During the Middle Age Warming period the temperature was about almost 2 degrees Fahrenheit warmer than now. The icecaps did not melt and the seas did not drown the coasts. In fact human kind flourished due to increased crop yields and the Vikings were farming in Southern Greenland. This was pre industrial revolution and thus had nothing to do with CO2.
The Vostok ice cores show that the CO2 levels rise after the earth warms and not prior. This is a function of the solubility of CO2 in the ocean as a function of water temperature. When the world warms the Oceans releases more CO2.
The medieval warming period coincided with increased solar activity. The little ice age which was devastating for humanity coincided with decreased solar activity. Current solar activity is declining dramatically. It is likely that we are heading into a new little ice age.
The sun is our heater and the thermostat is being turned down a little.
The global warming gang is about expanding the power of the state and be damned the effects on the subjects of the state. They also lie and know they are lying. Al Gore recently bought beachfront property.
....to increase it's magnetic field....
and make a good crop of sunspots before elections in 2016....
(PhysOrg.com) -- Sunspot formation is triggered by a magnetic field, which scientists say is steadily declining. They predict that by 2016 there may be no remaining sunspots, and the sun may stay spotless for several decades.
The last time the sunspots disappeared altogether was in the 17th and 18th century, and coincided with a lengthy cool period on the planet known as the Little Ice Age....and lasted 400 years.
Good luck surviving with no electricity and GE modified seeds.
I would expect that Greenland would be very fertile in a warming period. Melt runoff from glaciers would keep fields well irrigated.
