Unprecedented water level rise in Somalia

... water was now passing into Central Somalia. Heavy rain was also expected to continue into next week. In Jowhar, 90 kilometres north of the capital Mogadishu, three villages were affected by breaks in the river.

Survey finds silver contamination in North Pacific waters

...rogen and sulfur compounds that contribute to acid rain and smog. Previous studies by Flegal's group have also found high mercury levels in rainfall on the U.S. West Coast, which they linked to contamination from coal burning in Asia. "Unlike mercury, silver is not a human health concern. But silver is s...

Atmosphere may cleanse itself better than previously thought

...t: either water droplets in clouds absorb them and rain them out, or sunlight strikes them and the energy breaks the molecules apart. "The third way is the one we are concerned with here, the way that involves breaking these hydrocarbons down chemically," Francisco said. "For that, the atmosphere relies ...
