“In fact,” said Willis, “these natural climate phenomena can sometimes
hide global warming caused by human activities. Or they can have the
opposite effect of accentuating it.”

Larger Pacific Climate Event Helps Current La Nina Linger
ScienceDaily (Apr. 22, 2008) – Boosted by the
influence of a larger climate event in the
Pacific, one of the strongest La Niñas in many
years is slowly weakening but continues to
blanket the Pacific Ocean near the equator, as
shown by new sea-level height data collected by
the U.S.-French Jason oceanographic satellite.
This La Niña, which has persisted for the past
year, is indicated by the blue area in the center
of the image along the equator. Blue indicates
lower than normal sea level (cold water). The
data were gathered in early April.
