New Research Shows Global Warming Speeding Up | Common Dreams

And we have seen nothing yet. Once all the ice on the North Pole
disappears is when things will really speed up and another positive feedback 
kicks
in.

And the release of methane from undersea hydrates and CO2 from thawed
tundra.

That has not even started yet really. It takes about as much energy to melt
ice as it does to warm up seawater by one degree C. Only when the ice is
gone you'll see the warming start.
Put some ice cubes in a glass of your favorite drink and swirl it around
from time to time. As long as there is ice at all the temperature stays low.
Once the ice is gone the warming up starts.
And also all that ice was reflecting a lot of the solar energy straight back
into space when the ice is gone more energy will be captured.
And then we will see methane bubbling or spouting up. Trillions of tons of
it. All positive feedbacks.

The exacerbated warming trends you describe will doubtless cause significant 
heat waves and drought dramatically affecting agriculture with devastating
repercussions for third world and subsistence farmers as well as all the rest 
of them, including broadacre farms in the midwest and upper midwest USA
such as we have seen over the past year, in the news.

And the CO2 release from Arctic tundra thawing, CO2 release from land and 
rainforest clearing with soil disturbance
associated with activity only fools call agriculture.
