Most plants are nitrogen, phosphorus, or potassium limited in the environment. Take any study that mentions greater plant growth due to CO2 with a big grain of salt. Very few plants see increased growth under natural conditions plus more CO2, poison ivy being a notable exception. All the studies I've read so far that show increased growth due to CO2 had unnaturally high amounts of all other nutrients available. That just isn't the case in nature. PS: A farm field is NOT a natural condition. Farm fields are modified by the application of nitrogen, phosphorus, potassium, and sometimes other nutrients.

And what happens when the buffering limits are exceeded? There is research that is suggesting we are already putting out much more CO2 than nature can buffer, and have been for many years.

Rather than spending money on half baked technologies I think the money would be better spent on research at this point in time. I'm not sure we're gonna get more efficient wind turbines so putting them up now might be a good idea.
Wind turbines are very efficient now, and need to be built now. Every watt of productrion they produce is that much less fossil fuels needed to be burned, and thus that much less CO2 produced. What we need NOW is a huge expansion in the electrical grid. There is more wind energy available in the USA than the whole world uses. The problem is getting the energy from where it is produced to where it is needed.

The production of solar cells now takes a fraction of the energy it did just a couple decades ago. That is part of the reason Solindra was at an economic disadvantage. Their plant was a generation behind on the energy use curve. New solar cell process equipment being installed in new plants now uses less than half the energy the equipment Solindra plant used. Solar is there when it comes to overall energy use during it's life cycle. Improvements will be made, but there is no reason not to put it in now other than initial cost.

Fusion power is 25 to 50 years out...

Reagan cut funding for fusion research drastically. We'd be 20 years closer now if that hadn't happened.

Reagan also cut lots of other research on alternative energy solutions.
While the article mentions the ice area this year is above average, it doesn't mention that it is still under the average of the peak highs. They do mention mass, but then only talk of area as if it equates to mass, nice diversion. There has been a noticeable thinning of the water supported ice in both the ice shelves, and sea ice. There has also been a noticeable thinning of the ice in the glaciers that feed the ice shelves, and the areas they drain ice from. The overall mass of the ice in Antarctica is decreasing. This is despite the fact that it is snowing more down there. I don't have direct links today, but most of this I read up on over at Science Daily.
Want some scary numbers on global warming?
http://www.rollingstone.com/politics/ne ... h-20120719Only 16 years of burning fossil fuels like we have been and we are past the point of no return. Pay attention to what is said on how much there is still under ground, the valuation of the fossil fuel companies and the likelihood of how much of what under ground will be burnt. We're in for a whole lot of hurt climate wise.
