Reducing soot from burning is our fastest & least expensive first step to combat global warming. Unfortunately it is primairily a developing nation issue, so the U.N. advocates insufficient CO2 emission cuts instead that fail to address the problem instead of pursuing the most easily addressed culprits: black soot emissions & global population growth.
Banning a small number of cooking fires in one country only would be yet another feel-good measure that would only mislead us into thinking we're doing something productive about the problem.
In the U.S., 30% of our air pollution currently arrives on the Pacific Coast from Asia. That is a far bigger problem to solve than backyard barbeques. U.S. companies cause the problem by allowing their suppliers to pollute in Asia. Out of sight, out of mind. Either they, or global governments, could resolve the problem in no time. Backyard chefs can not.
Wal-Mart alone could almost single-handedly resolve the problem by setting standards for air pollution, & for the mix of power used by their suppliers. Wal-Mart has more money, power, & influence than all but a few of the largest world governments. Wal-Mart does not just serve as a proxy for the problem, they r a major facilitator of the problem.
Let is focus the conversation on the real issues, not the totally ineffective & misleading feel-good responses like this backyard barbeque ban.

Study Identifies Contribution of Man-Made Soot to Warming in Greenland in the Early 20th Century

New study: Ordinary soot second biggest driver of climate change
http://gristmill.grist.org/story/2008/3/24/03319/6577
After carbon dioxide, the second largest contributor to global warming is ordinary soot, according to new research published Sunday in Nature Geoscience. So-called ''black carbon'' has up to 60 percent the warming effects of the more oft-noted culprit CO2.
The implication is fairly radical: Quickly reducing soot could have substantial short-term effects on the rate of climate change. Whereas CO2 molecules stay in that atmosphere for years, soot particles stay about a week.
(In 2006, U.S. EPA is Stephen Johnson released soot standards substantially weaker than his scientific advisers recommended.)
Since 40 percent of soot comes from power sources, mainly coal & oil, that also produce CO2, measures to reduce soot would likely reduce other GHGs as well.
Reducing Black Carbon, or Soot, May Be Fastest Strategy
for Slowing Climate Change
http://igsd.org/docs/BC%20Briefing%20Note%2027Mar08.pdf
Emissions from black carbon (BC), or soot, r the second largest contributor to global warming after carbon dioxide (CO2) emissions, & reducing these emissions is the fastest strategy for slowing climate change. In some regions, such as the Himalayas, the impact of BC on melting snowpacks & glaciers may be equal to that of CO2.2 BC emissions also significantly contribute to Arctic ice-melt, & reducing such emissions may be “the most efficient way to mitigate Arctic warming that we know of.”3 Since 1950, developed countries have successfully reduced BC emissions by a factor of five, primarily to improve public health, & “technology exists for a drastic reduction of fossil fuel related BC” in the rest of the world.
The other 60 percent comes from burning biomass, mainly in the developing world, where a great deal of wood is burned for heating & cooking & forests r burned to clear them for agriculture.
