For many urban cities, there’s smog of one sort or the other in the trophosphere. For much the planet, there’s accumulating greenhouse gases warming in the upper atmosphere. Now there’s something new and alarming occurring in the Far East in between in a light-killing, resource-imperiling phenomeon.
Thursday, November 20th, 2008Call them “Brown clouds” for now. They are a cousin of global aminal, producing many of the same life-changing crisies from undiluted emissions of modern life. Carbon soot, manmade particles and a brew of chemicals kicked up from the burning of fossil fuels, wood and plants in this regional haze over Asia are threatening food supplies, public health, and are contributing to glacial melting. Just as alarming for the millions living under the brown clouds, light has been dramatically cut.
From the MSNBC story (link):
“The huge plumes have darkened 13 megacities in Asia — including Beijing, Shanghai, Bangkok, Cairo, Mumbai and New Delhi — sharply “dimming” the amount of light by as much as 25 percent in some places … Imagine for a moment a 3-kilometer-thick band of soot, particles, a cocktail of chemicals that stretches from the Arabic Peninsula to Asia,” said Achim Steiner, U.N. undersecretary general and executive director of the U.N. environment program. “All of this points to an even greater and urgent need to look at emissions across the planet because this is where the stories are linked in terms of greenhouse emissions and particle emissions and the impact that they’re having on our global climate,” he said. “
Sometimes you pick the crisis to fix. Sometimes it picks you. Might, out of all this worldwide financial turmoil, come a new covenant to eliminate gas-powered cars and dirty factories sooner than later because of the mounting damage they’re causing? Global warming is no myth. It’s the severity of it that’s being debated. What, then, to make of millions of people living in shadowy heat?
