AFP - Typhoon Mirinae smashed through the Philippines overnight, killing at least one person and worsening floods in areas that were struggling to recover from recent deadly storms, officials said Saturday. ...The typhoon, which had maximum winds of 185 kilometres (115 miles) an hour, was the third major storm to hit the Philippines main island of Luzon in just five weeks, with the previous two claiming more than 1,100 lives.

New work suggests scientists and policy makers can't ignore interactions between greenhouse gases and light-scattering particles
Modeling the climate just got a little more complex. A new simulation that considers chemical interactions between various gases and atmospheric aerosols is giving scientists and policy makers better estimates of the climate-altering effects of those gases, scientists report. Some atmospheric gases -- known as greenhouse gases -- trap heat and boost the planet's surface temperature. This process keeps Earth habitable, but nowadays, many scientists say, the planet may be getting too much of a good thing. Though most climate simulations include the direct, heat-trapping effects of these atmospheric constituents, which can readily be measured in a lab, few account for how their presence either increases or decreases atmospheric concentrations of planet-cooling aerosols, says Drew Shindell, a climate scientist at NASA's Goddard Institute for Space Studies in New York City. "These effects are generally understood but not well quantified," he notes. .... New portions of the revised model consider the influence of methane, carbon monoxide and nitrogen oxides on the atmospheric concentration of hydroxyl radicals, highly reactive molecules sometimes referred to as the atmosphere's detergent. Hydroxyl concentrations can be depleted as these radicals react with gases in the atmosphere, and this slows the reactions that produce light-colored, light-scattering sulfate aerosols, Shindell says. "And a lower number of aerosols means a lower cooling effect," he notes. Analyses using the revised model suggest that the aerosol-stifling power of methane and carbon monoxide considerably boosts the planet-warming effect of these gases. Previous studies have shown that a kilogram of methane, over the course of a century, warms Earth about 25 times more effectively than a kilogram of carbon dioxide does. But add in methane's hydroxyl-consuming effect, and its planet-warming potential jumps to 28 times that of CO2, an increase of 12 percent, Shindell says. (Scientists use carbon dioxide as a baseline largely because it is a common, long-lived greenhouse gas in the atmosphere and its warming effects are well known.) Similarly, carbon monoxide's greenhouse warming potential rises from 2.2 times to 3.3 times that of CO2 when its hydroxyl-consuming effect is considered. If the inhibiting influence of these two gases on the formation of planet-cooling clouds is also incorporated into the model, their greenhouse effect increases even further.
