North Pole Could be Ice-Free This Summer

Arctic sea ice could break apart completely at the North Pole this year, allowing ships to sail over the normally frozen top of the world.

The potential landmark thaw - the first time in human history the pole would be ice-free - is a stark sign of global warming, according to an article Friday on the web site of the The Independent, a London newspaper.

"Symbolically it is hugely important," said Mark Serreze of the U.S. National Snow and Ice Data Center in Colorado. "There is supposed to be ice at the North Pole, not open water."

Last year, the fabled Northwest Passage opened as Arctic ice retreated more than ever before.

There is no land at the North Pole, but as long as anyone has looked, it has remained a giant block of ice year-round. Scientists have been watching Arctic sea ice melt more and more each year. But each summer in recent years, the amount of ice has gotten thinner and thinner. Each winter's freeze, therefore, results in a thinner pack that, this summer, could melt altogether.

"The issue is that, for the first time that I am aware of, the North Pole is covered with extensive first-year ice," Serreze is quoted by The Independent. "I'd say it's even-odds whether the North Pole melts out."

Russia and other countries, meanwhile, have been arguing over who has rights to the region's resources, including potential oil reserves.

Several studies in recent years have predicted that the North Pole could be ice-free within a few decades. Alarm has ratcheted up every summer as the ice gets thinner and thinner. In a study released June 10, scientist said the rapid meltoff in the Arctic could threaten permafrost in continental soil elsewhere above the Arctic circle in a warm version of the snowball effect.

Last summer saw a record melt of Arctic sea ice, which shrank to more than 30 percent below its average. Around the peak of the melt, in September, air temperatures over land in the western Arctic from August to October were more than 4 degrees Fahrenheit (2 degrees Celsius) above the 1978-2006 average.

"The rapid loss of sea ice can trigger widespread changes that would be felt across the region," said Andrew Slater, also of the National Snow and Ice Data Center.

Soy Products Can Reduce Sperm Counts!

By: Heather Hajek Published: Friday, 25 July 2008 www.healthnews.com C alling all men who want to become fathers! Soy products may reduce a man's sperm count. Based on a recent study, men who consume soy products may have lower sperm counts than those who don't. The study was based on a small group of men who visited the Massachusetts General Hospital Fertility Center from 2000 to 2006. Even though the study found that some of the men who ate soy products on a regular basis had lower sperm counts, the researchers conducting the study are not saying that soy products were the cause of the lower sperm concentrations. The men who had soy products in their diets recorded lower sperm counts than those that didn't, but their counts were still within the normal range. Researchers don't deny that during the study men who consumed soy products had lower sperm counts, but they want people to realize there are other factors other than soy products that may have played a role in th...

Obesity linked to quantity of sleep!

P eople who sleep fewer than six hours a night - or more than nine - are more likely to be obese, according to a new US study that is one of the largest to show a link between irregular sleep and big bellies. The study also linked light sleepers to higher smoking rates, less physical activity and more alcohol use. The research adds weight to a stream of studies that have found obesity and other health problems in those who don't get proper shuteye, said Dr Ron Kramer, a Colorado physician and a spokesman for the American Academy of Sleep Medicine. "The data is all coming together that short sleepers and long sleepers don't do so well," Kramer said. The study is based on door-to-door surveys of 87,000 US adults from 2004 through 2006 conducted by the National Centre for Health Statistics, part of the Centers for Disease Control and Prevention. Such surveys can't prove cause-effect relationships, so - for example - it's not clear if smoking causes sleeplessn...

Women with long nails speak out against iPhone design.

M ost people either love or hate the iPhone's touch screen, and based on a report on the LA Times , women with long fingernails are among the haters. Why? Well, since the iPhone's touchscreen only responds to electrical charges emitted by your bare fingertips, women with long nails are left out in the cold. A woman interviewed for the article went so far as to suggest Apple was being misogynistic because it did not include a stylus for women and didn't consider womens' fingers and nails when designing the phone. Honestly, though, this same argument has come up against keyboards, touch screen monitors, and anything else that involves the use of your fingers, so should every gadget maker change the design of its products to accommodate users with long nails, or should people with long nails learn to work around this problem like they have in the past? I'd love to hear what Apple has to say about all this, but I doubt they'll ev...
