Given the day of financial reckoning to come, only delayed a bit by GWB’s bailout (the largest since the Great Depression), maybe ”Get Out Of Town” would have been a more helpful headline for you. But enough of my obsessions.
White roofs, streets could curb global warming from PhysOrg.com
The idea of painting our roofs and roads white to offset global warming is not new, but a recent study has calculated just how significantly white surfaces could impact greenhouse gas emissions. Last week, researchers at Lawrence Berkeley National Laboratory and UC Berkeley presented their study at California’s annual Climate Change Research Conference in Sacramento.
White coatings are cheaper than installing rooftop gardens, but “green roofs” fight heat islands in a city, and with the plants absorbing CO2 directly, are probably no worse despite the darker color absorbing solar energy. Taking the heat absorbed by the solar electric panels into account as well as their power generation would be interesting.
Compared to rural areas, cities experience higher rates of heat-related illness and death. The heat island effect is one factor among several that can raise summertime temperatures to levels that pose a threat to public health.
There I go again.
