The World Meteorological Organization (WMO) said it saw unprecedented signs pointing to a looming La Nina, a phenomenon that originates off the western coast of South America but can disrupt weather patterns in many parts of the globe.
The buildup of this La Nina was so exceptionally swift and intense that it was impossible at the moment to infer what the impact would be, and how long the phenomenon would last, it warned.
Over the 72-hour period ending at 5 a.m. today, Punaluu saw 22.84 inches of rain. Kahuku was not far behind at 12.26.
Joining the growing list of places on this planet that are melting, Antarctica is losing some 36 cubic miles of ice every year, scientists said today.
For comparison, Los Angeles consumes roughly 1 cubic mile of fresh water a year.
The south polar region holds 90 percent of Earth's ice and 70 percent of the total fresh water on the planet, so any significant pace of melting there is important and could contribute to an already rising sea.
"This is the first study to indicate the total mass balance of the Antarctic ice sheet is in significant decline," said Isabella Velicogna of the University of Colorado at Boulder.
On Saturday, Feb. 25, at 7:16 p.m. Eastern Standard Time, the population here on this good Earth is projected to hit 6.5 billion people.
Along with this forecast, an analysis by the International Programs Center at the U.S. Census Bureau points to another factoid, Robert Bernstein of the Bureau's Public Information Center advised LiveScience. Mark this on your calendar: Some six years from now, on Oct. 18, 2012 at 4:36 p.m. Eastern Daylight Time, the Earth will be home to 7 billion folks.
RADIATION detectors in Britain recorded a fourfold increase in uranium levels in the atmosphere after the "shock and awe" bombing campaign against Iraq, according to a report.
Environmental scientists who uncovered the figures through freedom of information laws say it is evidence that depleted uranium from the shells was carried by wind currents to Britain.

A former US military researcher tells Gay Alcorn of his crusade to expose the health risks of depleted-uranium weapons used in the Gulf wars.
Doug Rokke sits on the edge of his chair in a beige, could-be-anywhere hotel room in Carlton. He stares at you with an almost embarrassing intensity and is close to tears.
"It's lonely," he says slowly. "It's very lonely. I made a decision. I was given a job. I did my job. I learned something. I gave them an answer they didn't want. I became persona non grata. And the better parts of my life ended."
What remains is an obsession with proving he is right about the dangers of depleted uranium (DU) weapons. A waste produced from the uranium enrichment process, depleted uranium has become increasingly contentious since American and British militaries first used it in the 1991 Gulf War and, since then, in the Balkans, Afghanistan and Iraq.
Rokke, a health physicist who became the Pentagon's most senior DU expert during the first Gulf War, became convinced it had contaminated the battlefield and could be a factor in Gulf War Syndrome, the mysterious mix of illnesses that have afflicted returning soldiers. Rokke acknowledges DU's brilliance as a weapon - because it is an extremely dense metal that sharpens and burns as it hits its target, it is used on the ends of tank shells and missiles to penetrate steel and concrete much more easily than conventional weapons. But he also believes that he and the research team became contaminated. "Everybody is sick," he says. "We've all got rashes, respiratory and kidney problems. It's there; there are no two ways about it."
Rokke is a military veteran. He joined the US Air Force in 1967 and bombed Vietnam targets "before I could shave". Years later, with a master of science and expertise in environmental health, he was ordered to the Gulf to help protect American soldiers if chemical and biological weapons were used and, later, to oversee DU clean-up. He became convinced DU was causing illnesses such as cancer, and that the Pentagon was downplaying its dangers. When he went public with his views, he was sacked
Based on a depleted-uranium penetrator, the West Virginia-produced round is billed as the most advanced armor-piercing kinetic-energy ordnance available.
"Its state-of-the-art composite sabot, propellant, and penetrator technologies give it outstanding accuracy and lethality," ATK said.
How do you feel about a nuclear weapon that could be launched from the back of a jeep?
The slightly bizarre idea of 'user-friendly' nuclear weapons. On the whole score of proliferation we're always hearing plenty about the dangers posed by the Irans and North Koreas of this world but, as we're about to see, while all that has been going on the US itself has been quietly beavering away on a program aimed at completely upgrading its nuclear arsenal, including the development of tactical weapons - mini-nukes that could be used on the battlefield.

Around 15 per cent of today's global warming is down to methane, but where does all this gas come from? Some at least could be bubbling up from an unlikely source - deep-sea volcanoes.
Until now, such volcanoes were thought to be a negligible source of atmospheric methane because everyone assumed the gas would oxidise long before it reached the surface. However, research on Håkon Mosby, a mud volcano 1250 metres down in the Norwegian Sea, has overturned this assumption.
"I DON'T think visitors appreciate that they're standing directly on top of the largest, most dynamic magmatic system on the planet," says geologist Daniel Dzurisin. While the supervolcano that is Yellowstone National Park won't be erupting any time soon, he and his colleagues have uncovered a surprising source of volcanic activity beneath tourists' feet, which was probably the reason trails had to be closed in 2003.
