A water deficit of that magnitude, if unmitigated, could potentially destabilize a politically volatile part of the world by reducing arable land in Egypt by up to 72%. The study projects that economic losses to agriculture would reach $51 billion. The gross domestic product loss would push unemployment to 24%, displacing lots of people and disrupting economies.

(Thom Quine photo) Facebook Share Temperatures of warming streams rather than inadequate oxygen levels lead to poorer growth in mayflies, which are often seen as an early indicator of stream health because of their sensitivity to environmental change, according to new research at Stroud Water Research Center. The results of a study at the Avondale, Pennsylvania, based research center disprove a common hypothesis that insects fare worse in warmer waters because of the temperature.
