"Now....countered with what?"
With less CO2 and more vegetation for instance.
Of course our earth has been through many a rough cycle. What makes this particular one interesting is
1: It was predicted
2: It is coming true and even more than predicted.
The warming curve is quite fast. Still, as a sidenote, the Glaciers up where I live were smaller than this 1100 years ago. Europe's biggest glacier today was split into 2 smaller glaciers untill perhaps the 12th century.
So indeed there are always changes. Here is another sidenote.
A very rough volcanic eruption can bring so many a dark particle into the atmosphere that it cools, - and quite a bit, - by simply blocking the sun away. Now, the greenhouse effect is the opposite, simple as that.
And glaciers sometimes give a lot out of water in other ways, - where I live.
Next sunday, we have an evacuation excercize. Some 90 km's away is a nasty volcano hiding under a massive icecap. When she blows, she melts the ice quite quickly, and a floodwave occurs, heading our way with the mass of 200.000 cubic metres pro second. Unstoppable and the biggest, meanest "river" in the world, with 1000 tonne chunks of Ice floating like champagne corks in the watermass.
So, point being, there is a lot of things happening that we cannot do anything about, but we CAN do something about the CO2 effect.
Oh, and a question. Someone above in the thread said he used only 250 gallons of gas a month. Is that private use? I run a farm, and don't use that much....
