But won't the CO2 burned in their construction wipe out any gains? I discuss this and the place of 'agroforestry' in our sustainable future in my weblog, http://solarukweblog.wordpress.com/, under the posting 'Chicken Feed'. SolarUK is at the forefront of advanced but increasingly cost-effective (as gas and electricity prices shoot upwards) renewable technologies, producing solar hot water systems which will work effectively in cooler climates.

Too many pepole today are still in denial about climate change and we won't have time to change our lifestyles enough to make any difference in the climate. I fear that our only hope will be some sort of scientific intervention.

In order to achieve the dream of sustainable development it's going to take a whole picture approach of looking for renewable energy, reducing CO2 emissions, recycling, and reforestation. The current practice of regulation on a country by country basis makes it extremely difficult for a coordinated effort. The UN efforts help, but greater participation is required.

Fertilization has been demonstrated to be a cost-effective method. "Recent marine trials suggest that one kilogram of fine iron particles may generate well over 100,000 kilograms of plankton biomass. . . The maximum possible result from this technique, assuming the most favourable conditions and disregarding all practical considerations,is 0.29W/m2 of globally-averaged negative forcing[5], which is almost sufficient to reverse the warming effect of about 1/6th of current levels of anthropogenic CO2 emissions." http://en.wikipedia.org/wiki/Iron_fertilization

The technique has been tried and found to be effective more than every other technique mentioned except land use and forestation.

If it's not going to get fixed – nothing will work and things will only get worse.
