Carbon storage faces costly hurdles

There are 2 comments on the Reuters story from Jun 2, 2009, titled Carbon storage faces costly hurdles. In it, Reuters reports that:

The CEO of Kinder Morgan Energy Partners LP said on Tuesday that the pipeline giant will not enter the market to sock away heat-trapping greenhouse gases in underground reservoirs unless the U.S. government settles who is legally liable if the gas leaks out.

Pie in the sky idea. HIgh pressure CO2 kept underground for virtual infinity? Millions of tons of it? Then why can't we find a place underground to put the nuke waste? I doubt CO2 sequestration will work. Odds are against it.

Why do we allow idiot human being to deprive plants the plant food the need to then feed other humans?
We should commit AGW crisis loons to the institutions for the Duh?- Huh?- stupid.

the last two decades of the twentieth century were a good time to be a plant on planet Earth. In many parts of the global garden, the climate grew warmer, wetter, and sunnier, and despite a few El Niño-related setbacks, plants flourished for the most part.

When scientists talk about productivity they are specifically talking about how much carbon ends up stored in the living biomass—roots, trunks, and leaves of plants—after they tally up carbon gains through photosynthesis and carbon losses through respiration. This tally of gains minus losses is called “net primary production.”

Colorado State University conducted tests with carnations and other flowers in controlled CO2 atmospheres ranging from 200 to 550 ppm. The higher CO2 concentrations significantly increased the rate of formation of dry plant matter, total flower yield and market value.

Research has shown that in most cases rate of plant growth under otherwise identical growing conditions is directly related to carbon dioxide concentration.

The amount of carbon dioxide a plant requires to grow may vary from plant to plant, but tests show that most plants will stop growing when the CO2 level decreases below 150 ppm. Even at 220 ppm, a slow-down in plant growth is significantly noticeable.

Scores of laboratory and field studies show that higher CO2 concentrations help most plants grow faster, stronger, and more profusely, utilize water more efficiently, and resist pollution and other environmental stresses.[102]

Needless to say, all animals directly or indirectly depend on plants as a food source.

Based on numerous empirical studies, the 100ppm increase in atmospheric CO2 content over the past 150 years has increased mean crop yields by the following amounts:
wheat, 60 percent;
other C3 cereals, 70 percent;
C4 cereals, 28 percent;
fruits and melons, 33 percent;
legumes, 62 percent;
root and tuber crops, 67 percent;
and vegetables, 51 percent.[103]

Were it not for the extra CO2 put into the atmosphere by fossil fuel combustion, either many people now living would not exist, or many forests now standing would have been cleared and turned into farmland—or both.

CO2 emissions are literally greening the planet, enhancing biodiversity and global food availability. Continuing CO2 enrichment of the atmosphere will be necessary to feed a global population expected to increase by 3.3 billion over the next 50 years—and limit pressures to convert forests and wetlands into cropland.[104]
