2010–2012 La Niña event
The 2010–2012 La Niña event was one of the strongest on record. It caused Australia to experience its wettest September on record in 2010, and its second-wettest year on record in 2010. It also led to an unusual intensification of the Leeuwin Current, the 2010 Pakistan floods, the 2010–2011 Queensland floods, and the 2011 East Africa drought. It also helped keep the average global temperature below recent trends, leading to 2011 tying with 1997 for the 14th-warmest year on record. This La Niña event also led to above-average tropical cyclone activity in the North Atlantic Ocean during the 2010, 2011, and 2012 hurricane seasons, while the Eastern and Western Pacific experienced record low activity in 2010 and below average activity in 2011.
