A surge in sunshine more than 60 years ago helped Swiss mountain glaciers melt faster than today, even though warmer average temperatures are being recorded now, Swiss researchers said Monday. http://www.physorg.com/news180024364.html Space & Earth Mon, 14 Dec 2009 15:00:03 EST news180024364 Those pristine-looking Alpine glaciers now melting as global warming sets in may explain the mysterious increase in persistent organic pollutants in sediment from certain lakes since the 1990s, despite decreased use of those compounds in pesticides, electric equipment, paints and other products. That's the conclusion of a new study, scheduled for the Nov. 1 issue of ACS' Environmental Science & Technology. http://www.physorg.com/news175337686.html Space & Earth Wed, 21 Oct 2009 09:55:42 EST news175337686 Climate researchers have shown that big volcanic eruptions over the past 450 years have temporarily cooled weather in the tropics -but suggest that such effects may have been masked in the 20th century by rising global temperatures. Their paper, which shows that higher latitudes can be even more sensitive to volcanism, appears in the current issue of Nature Geoscience. http://www.physorg.com/news150397996.html Space & Earth Mon, 05 Jan 2009 17:13:16 EST news150397996
