2000 was another La Niña year, and brought an abnormally warm winter and spring to the United States, particularly in the southern and western parts of the country. The Midwest and northeast experienced a cooler second half of the year. November and December became very cold, with more than 50% of the country experiencing very cold temperatures.
US Temperature Anomalies, 2000
Most of the country had drought or dry conditions, but the Great Lakes and northeast regions received more-than-average precipitation. According to the Palmer Index, 16% of the country was in drought in January, peaking at 36% in August. Meanwhile, 5% was extremely wet. In summer, wildfires in the western states destroyed 7.3 million acres of forest. Dry conditions in that region had persisted since 1999. The worst droughts occurred throughout the Deep South (Alabama, Florida, Georgia, Louisiana, and Mississippi).
Southeastern Europe experienced
extremely high temperatures followed by water shortages in late summer. Meanwhile,
precipitation in Britain and western Europe fluctuated between dryness in the
first three months of the year, to extreme amounts in the second three months, back
to dryness in summer, followed by a wet and stormy autumn across most of
Europe.
Tomorrow: 2000 state of the world
climate.
Be brave, and be well.
