Global greening/CO2 Fertilization

As early Greenpeacer turned sensible environmentalist Dr. Patrick Moore suggests we should be celebrating CO2 and increasing levels will be a boon for the biosphere.

"CO2 is the currency of life and the most important building block for all life on Earth. All life is carbon-based, including our own. Surely the carbon cycle and its central role in the creation of life should be taught to our children rather than the demonization of CO2, that “carbon” is a “pollutant” that threatens the continuation of life. We know for a fact that CO2 is essential for life and that it must be at a certain level in the atmosphere for the survival of plants, which are the primary food for all the other species alive today. Should we not encourage our citizens, students, teachers, politicians, scientists, and other leaders to celebrate CO2 as the giver of life that it is?"

You can buy CO2 grow room kits and show yourself higher CO2 levels are good for plants.

"While normal outdoor CO2 levels (about 400ppm) will achieve normal plant growth, doubling or tripling the CO2 levels can increase the growth rate. However, above 2,000ppm CO2 becomes toxic to plants, and above 5,000ppm CO2 becomes potentially harmful to people. Most experts agree that 1,500 ppm is the maximum CO2 level for maximum plant growth, although any CO2 level between 1,000ppm and 1,500ppm will produce greatly improved results."

.......................
From the CSIRO report

For dry Australia, however, more than half (64%) of the rainfall returning to the atmosphere does not go through vegetation, but through direct soil evaporation.
This reduces the potential benefit from increased vegetation water use efficiency and the possibility for more water flowing to rivers and reservoirs.
In fact, a recent study shows that while semi-arid regions in Australia are greening, they are also consuming more water, causing river flows to fall by 24-28%.

Our research confirms that plants all over the world are likely to benefit from these increased water savings. However, the question of whether this will translate to more water availability for conservation or for human consumption is much less clear, and will probably vary widely from region to region.

Saw yesterday on a TV show in Australia a CSIRO scientist give a rough figure for water per calorie, I think it was 1 litre per calorie ????

another CSIRO experiment
Carbon emissions are not soaked up by trees as well as initially thought, say scientists
In a world-first experiment, experts exposed a plantation of eucalypts to the same level of carbon expected to be in the atmosphere in 35 years' time.
Professor David Ellsworth, who led the study, said while the trees captured the carbon well up to the present day, they could not capture more.

"We saw no growth response to the trees, to the elevated CO2, and we saw no productivity response either," he said.

"That means that the trees are actually soaking up more CO2, but potentially also just spitting it back out, so to speak, and not storing it.

thanks for those excellent posts and links, SM. I'm sure some will have trouble understanding and appreciating them... :roll:
