By: John Boonstra on August 31, 2009 In addition to planting fake plastic trees, another simple “geo-engineering” measure, suggests Brad Plumer (via Yglesias), is to “paint all our roofs white, reflecting more of the sun’s heat and cooling the Earth.” This obviously makes sense, and along with other standard home modification measures (solar panels, high-efficiency lighting, etc.), as well as some that are probably more instinctively unpopular — the fetish of having a perfectly green lawn (and not in the environmental sense) is not lying to die out soon — painting roofs while is indeed a “total no-brainer” in terms of reducing our environmental impact. The problem, as Matt recognizes, is that the farther that the geo-engineering scale tips toward the drastic (or the ridiculous), the less vigorously politicians feel compelled to push for costly reductions in carbon emissions. The point of trying to reclaim the term “geo-engineering” from the province of futuristic tubes pumping sulfur dioxide into the air does seem worthwhile. If it’s about painting houses, everyone can be a “geo-engineer,” and maybe we won’t have to worry as much about those rogue environmentalist billionaires.
