Global Warming And Land Use

United Press International: Analysis: Land use, climate change linked
Not only is paving the planet causing it to get hotter, but farming is contributing as well. Hmmm. What shall we do?

I’m only blogging on this to note that yet another article is out on global warming that ignores geoengineering altogether. The “Geritol Solution”, carbon sequestration and carbon nanotubes are all ignored completely, as is the case in all global warming articles even when they are about CO2 and not land use. I’ll worry about this problem when the proponents embrace technology as part of the solution in a way that actually solves the problem rather than delaying maximum temperature.

Current land use practices in the United States — from asphalt paving to irrigation — seem to be contributing twice as much to global climate change as scientists previously thought, a discovery that portends difficult decisions ahead for future land use planners, developers and zoning commissions.

New evidence comes from two University of Maryland researchers, who analyzed the impact of U.S. land use practices and found those practices have boosted the nation’s mean lower atmospheric temperature by 0.2 degrees Fahrenheit since the 1960s.

That is “quite important, about one-half of the total (climate) impact,” meteorology professor Eugenia Kalnay told United Press International. Land use change “is an additional factor that cannot be neglected,” she added.

Kalnay said the findings, published in the May 28 issue of the British journal Nature, do not mean greenhouse gases are less important in contributing to global warming. Rather, when the effects of land use practices are added in, the human impact on climate change might be even greater than previously thought.
