La Nina Extreme Weather Pattern May Double By Century’s End
(Click to enlarge) La Niñas, which are the cooler cousins of El Niños, are weather patterns associated with a temperature drop in the central Pacific Ocean.
Human-caused climate change will double the frequency of La Niñas by the end of the century, resulting in floods, droughts and other extreme weather events, finds a new study based on climate modeling.
(From Scientific American / Gayathri Vaidyanathan)– La Niñas, which are the cooler cousins of El Niños, are weather patterns associated with a temperature drop in the central Pacific Ocean. In the past, extreme La Niñas have caused droughts in the southwestern United States, flash flooding in Venezuela, flooding in China and the deaths of thousands of people.
Research by Wenju Cai, an atmospheric scientist with the Commonwealth Scientific and Industrial Research Organisation in Australia, and his colleagues suggests that extreme La Niñas would occur once every 13 years with climate change in 2100, an increase from the once-in-every-23-years frequency seen in the 1990s. The study was published in Nature Climate Change. Read the full story »
