The La Nina cooling of the tropical atmosphere continued in March, with temperatures in the tropics falling to their coldest seasonally-adjusted temperature (-0.49 C below the 20-year average for March) since the La Nina of March 1989, according to Dr. John Christy, a professor of atmospheric science and director of the Earth System Science Center (ESSC) at The University of Alabama in Huntsville (UAH).

Tropical temperatures in March 1989 dropped -0.72 C (1.3 degrees Fahrenheit) below seasonal norms. Global trend since Nov. 16, 1978: +0.14 C per decade

March temperatures (preliminary):

- Global composite temp.: +0.09 C (about 0.16 degrees Fahrenheit) above 20-year average for March.

- Northern Hemisphere: +0.43 C (about 0.77 degrees Fahrenheit) above 20-year average for March.

- Southern Hemisphere: - 0.25 C (about 0.45 degrees Fahrenheit) below 20-year average for March.

February temperatures (revised):

- Global Composite: + 0.02 C above 20-year average

Data from faint earth tremors caused by wind-driven ocean waves-often dismissed as "background noise" at seismographic stations around the world-suggest extreme ocean storms have become more frequent over the past three decades, according to research presented at the annual meeting of the Seismological Society of America.
