News: Melting Ice...

Wednesday, August 6, 2008

I dont believe in Global Warming caused by people... maybe there is something bigger happening out there and we are just trying to find someone to blame. Yes we have and still keep polluting the only place we can call home... and of course we are going to have to pay for it.

" Even greater climate change could be on the way. Growing numbers of scientists fear that the warming trend will so disrupt ocean circulation patterns that the Gulf Stream, the current that warms large parts of the northern hemisphere, could temporarily shut down. If that happens, global warming would, ironically, produce global cooling ~ and bring on a deep freeze

The effect of the Solar storms on our lives

Monday, June 23, 2008

The onset of a new solar cycle is significant because of our increasingly space-based technological society.

"Solar storms can disable satellites that we depend on for weather forecasts and GPS navigation," says Hathaway. Radio bursts from solar flares can directly interfere with cell phone reception while coronal mass ejections (CMEs) hitting Earth can cause electrical power outages. "The most famous example is the Quebec outage of 1989, which left some Canadians without power for as much as six days."

Air travel can be affected, too.

Every year, intercontinental flights carry thousands of passengers over Earth’s poles. It's the shortest distance between, say, New York and Tokyo or Beijing and Chicago. In 1999, United Airlines made just twelve trips over the Arctic. By 2005, the number of flights had ballooned to 1,402. Other airlines report similar growth.

"Solar storms have a big effect on polar regions of our planet," says Steve Hill of the Space Weather Prediction Center. "When airplanes fly over the poles during solar storms, they can experience radio blackouts, navigation errors and computer reboots all caused by space radiation." Avoiding the poles during solar storms solves the problem, but it costs extra time, money and fuel to "take the long way around."
