La Niña could set the stage for flu pandemics

In 1918, the Spanish flu spread around the world, claiming between 50 million and 100 million lives — more than 3 percent of the world’s population. The previous fall and winter, La Niña had brought cooler-than-normal sea-surface temperatures to the central and eastern equatorial Pacific. More recently in 2009, swine flu swept across the planet. Again, the widespread outbreak was preceded by La Niña conditions. This link might be more than coincidental, according to new research, and could lead to improved predictions of future pandemics.
