Failing frogs

Article Abstract:

Global warming causes frogs to disappear and decimated frog species may be just the first in a wave of climate-induced extinctions, according to a clue discovered in the early 1990s, when researchers noted that two species of Latin America's brightly colored harlequin frogs were last observed following a particular warm year in the tropics. The frog infections are most likely the first in a coming series of 'climate-induced' epidemics.

A sea change: as the planet warms, the Nature Conservancy searches for new strategies

Article Abstract:

An in-depth report is presented on the impact of global warming on North Carolina's Roanoke River. The environmental changes are expected to cause more hurricanes, which in turn would cause ocean waters to flood the river, increasing its salinity and killing off native species. A sidebar is included regarding rain forest protection and reduction of atmospheric carbon dioxide.
