California drought, Australia floods: Two sides of La Niña amplified by climate change

California just notched its driest January and February on record, sounding alarms about a third year of record drought.

Across the Pacific Ocean, thousands are fleeing record flooding in Australia. Officials in Brisbane reported 31 inches of rain in six days, and Jonathan Howe, a government meteorologist quoted by the Associated Press, called the amount of rainfall “astronomical.”

Meanwhile, in the eastern Horn of Africa, prolonged drought is raising the frightening specter of famine for millions.
