White Roofs and Global Warming: A More Realistic Perspective « Roy Spencer, Ph. D.

From other sources I find that about 5% of U.S. energy use is for air conditioning. If we could reduce that by, say, ten percent through brighter roofs, then 0.5% (one half of one percent) of our energy demand could be alleviated.]

And as I mentioned at the outset, if climate sensitivity is low, then the warming effect of more CO2 (as well as the cooling effect of any geoengineering ‘fixes’ to the problem) will have little effect on global temperatures, anyway.

Other ideas to lessen global warming by enhancing albedo include releasing millions of small, shiny balloons into the atmosphere, or balloons carrying sulphur, or putting small, shiny light-weight spacecraft into orbit between the earth and the sun.

August '08: Kill-joy councils ban party balloons | NSW/ACT | News.com.au

THE simple magic of helium balloons has been popped – councils all over Sydney are banning them.

One kill-joy council ranger even attempted to stop a toddler playing with a balloon at a local festival.

The bureaucrat from Canada Bay Council threatened a priest handing a helium balloon to two-year-old Lewis Sylvester at the Five Dock Ferragosto festival last week.

The ranger rounded on the priest with the terse warning: "I've already told you once. You can't hand out those balloons, it's an offence."
