"The collapse of the earth's magnetic field, which both guards the planet and guides many of its creatures, appears to have started in earnest about 150 years ago, the NY TIMES is planning to report on Page Ones Tuesday.

Science reporter Bill Broad has filed a report, according to newsroom sources, which explores how: 'The field's strength has waned 10 percent to 15 percent so far and this deterioration has accelerated of late, increasing debate over whether it portends a reversal of the lines of magnetic force that normally envelop the earth."

Broad explains: "During a reversal, the main field weakens, almost vanishes, and then reappears with opposite polarity. Afterward, compass needles that normally point north would point south, and during the thousands of years of transition much in the heavens and Earth would go askew."

Broad claims: "A reversal could knock out power grids, hurt astronauts and satellites, widen atmospheric ozone holes, send polar auroras flashing to the equator and confuse birds, fish and migratory animals that rely on the steadiness of the magnetic field as a navigation aid."

"It is not a matter of whether it will happen, but when, said scientists who presented the latest research on the subject at a recent meeting of the American Geophysical Union in San Francisco.

But when is hard to pinpoint. The dipole reversal pattern is erratic.

"We can have periods without reversals for many millions of years, and we can have four or five reversals within one million years," said Yves Gallet, from Institut de Physique du Globe de Paris, France, who studies the palaeomagnetic record and estimates that the current decay started 2,000 years ago."

It explains the many strange things that are happening around us. The polar shift is coming closer.

Where are the pelicans?

"Chase Lake National Wildlife Refuge, N.D. — The air here this time of year usually is filled with the grunts and squawks of thousands of white pelicans and their chicks. The giant birds have made the refuge their home for at least 100 years.

Now their nesting grounds are quiet. The pelicans are gone — and no one knows why.

The refuge – almost 18 square kilometres -- in central North Dakota had been known as the home of the largest nesting colony of white pelicans in North America. The nearly 28,000 birds that showed up to nest here in early April took off in late May and early June, leaving their chicks and eggs behind."
