April 2006 was the warmest April on record in the U.S. since record keeping began in 1895. The U.S. has now had two "warmest ever" months this year, January and April. The nationally averaged April temperature was 56.5°F (13.6°C), which was 4.5°F (2.5°C) above the 1901-2000 (20th century) mean. Globally, April ranked as the 7th warmest April on record, and the period January through April ranks as the 6th warmest such period on record globally. From Figure 1, we can see that the entire tropical Atlantic region where hurricane formation occurs was warmer than average during April, and this region has remained about .5 - 1.5 degrees C above normal over the past few months.Ahí queda eso.
