Devastating El Nio events to double this century

New Scientist: Extreme El Nio events, that can kill tens of thousands of people, will be twice as common this century because of climate change. The finding adds to the evidence that global warming will cause ever more extreme weather. The El Nio Southern Oscillation (ENSO) is one of the most powerful phenomena controlling global weather. An El Nio happens when warm water spreads across the surface of the Pacific, pushing rainfall to the east and causing floods in the Americas and drought in Australia. An El...

Unchecked global warming 'will double El Nio weather events'
2014-01-19 19:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: The world's most devastating global weather phenomenon the weather events associated with "El Nio" will double in frequency to once a decade if global warming remains unchecked, according to what scientists believe is a major step forward in the understanding of such events. The last extreme El Nio, in 1997-98, resulted in the hottest year on record, and the accompanying floods, cyclones, droughts and wildfires killed an estimated 23,000 people and caused 21bn-28bn in damage, particularly...

El Nio Activity Increased Over Last Century, New Research Suggests
2013-10-28 22:33:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: The past century of the El Nio Southern Oscillation (ENSO) weather phenomenon has been unusually active compared to the previous 600 years of activity, according to new research published in the journal Climate of the Past. The international team behind the research, which included scientists from University of New South Wales, the University of Hawaii International Pacific Research Center and the NOAA Geophysical Fluid Dynamics Laboratory, looked to the past to interpret current El Nio-related...

Warming could make El Nio more intense
2013-10-15 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Australian Broadcasting Corporation: El Nino future Global warming is expected to increase the severity of droughts and floods due to El Nio in the tropical Pacific, new Australian research has found. Dr Scott Power, from the Centre for Australian Weather and Climate Research, and colleagues, report their findings today in the journal Nature. During El Nio, the ocean surface temperature in the eastern Pacific warms and this leads to droughts in the western tropical Pacific and floods in the eastern part. This in turn has...

Global Warming Could Alter the Strength of El Nio
2013-09-11 20:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: Global warming could impact the El Nio Southern Oscillation (ENSO), researchers have found, resulting in changes in the El Nio and La Nia weather cycles known to cause drought and flooding in Australia and other Pacific-rim countries. Published in Nature Geoscience, the study uses coral samples to track the last 4,300 years of the ENSO cycle. The results suggest that El Nio events are easily influenced by external changes. "Our research has showed that while the development of La Nia and...
