The San Rafael Glacier in the Northern Patagonian Ice Field

The San Rafael Glacier in the Northern Patagonian Ice Field

MELTING mountain glaciers are contributing to the fastest sea level rise in 350 years, according to research by Welsh scientists.

The team from Aberystwyth University, the University of Exeter and Stockholm University undertook a survey of the 270 largest outlet glaciers of the south and north Patagonian icefields of South America.

They mapped changes in the position of the glaciers since the Little Ice Age, which was the last time in the recent past when they were much larger.

The team calculated the volume of ice lost by the glaciers as they have retreated and thinned over the past 350 years and compared these volume losses to rates of change over the last 30 years.

They found that the rate at which the glaciers are losing volume over the past 30 years is between 10 and 100 times faster than the 350- year long-term average.

The study, which has been published in the journal Nature Geoscience, concludes the mountain glaciers have rapidly increased their melt rate in recent years and consequently their contribution to global sea level.

Lead author, Professor Neil Glasser of Aberystwyth University, said the work was based on a longer timescale than any earlier glacier research conducted.

The second author Dr Stephan Harrison of the University of Exeter, said: “The work is significant because it is the first time anyone has made a direct estimate of the sea-level contribution from glaciers since the peak of the Industrial Revolution.”

NASA admits all previous warming trends caused by sun

I wonder what Al Gore’s rebuttal is going to sound like…

Under mounting pressure from scientists that reject the politically popularized man-made global warming and climate models—the Anthropogenic Global Warming (AGW) theory—the American space agency NASA has admitted that all past warming trends were driven by solar activity.

A victory for the man-made ‘global warming deniers’

As more scientists have joined the outcry over the politicization of Earth’s climate cycles—the current number exceeds 20,000—promoters of the AGW model have denounced the “global warming deniers” countering that little evidence supports the view that the sun is driving the observed warming trend.

Now, however, new study released from NASA’s Goddard Space Flight Center in Greenbelt, Maryland measuring the global temperature variance during the past 100 years has found the sun’s heat and variable cycles have indeed made a significant, measurable impact and greatly influenced Earth’s climate.

In fact, the influence extends as far back as the Read more…

Stonehenge Beneath the Waters of Lake Michigan

Has a Stonehenge like structure been discovered underneath the waters of Lake Michigan. If so, the site could be around 10,000 years old!

In a surprisingly under-reported story from 2007, Mark Holley, a professor of underwater archaeology at Northwestern Michigan University College, discovered a series of stones – some of them arranged in a circle and one of which seemed to show carvings of a mastodon – 40-feet beneath the surface waters of Lake Michigan.
If verified, the carvings could be as much as 10,000 years old – coincident with the post Read more…

Yellowstone supervolcano, new Ice Age could topple US government

February 9, 2011 Comments off

As evidence mounts that the world may fast be slipping into the next Ice Age, Washington insiders are hurrying to solidify a new power base for centralized government operations.

Fears that the US capital might be struck by another more deadly terrorist attack—or other disasters—prompted agencies a decade ago to hurriedly establish back-up operations in case catastrophe struck.

Despite the fact that many conspiracy theories are weaved around the subjects that follow—including some fairly wild-eyed, tin foil hat scenarios—most conspiracy theories have a basis in fact, although the facts are distorted or wildly exaggerated.

The actual story of the Denver airport, the nation’s “second capital,” the impending Ice Age possibility, and the threat the Yellowstone supervolcano presents to the people of the United States of America and their government follows: Read more…

Astronomy: “The Taurid Stream: A Cosmic Trail With Destruction In Its Wake”

“Over the next few weeks the Taurid stream, a procession of vast cosmic rubble and dust that snakes around the Sun and out towards Jupiter, will swing through Earth’s orbit for the first of its bi-annual crossings. Within the stream are probably thousands of bodies including asteroids, mountain-and island-sized boulders, smaller meteoroids, Encke’s Comet and assorted fragments of celestial refuse.

The exact number, size and location of objects, however, remains a mystery and according to Dr. Mark Bailey, research Fellow in astronomy at Manchester University, it is likely that for every object which is confirmed, there are nine others that have so far eluded detection. All that is certain is that the rubble, believed by some astronomers to have been formed by a collision in the asteroid belt of a defunct comet which was captured by the solar system up to 30,000 thousand years ago, will bisect Earth’s orbit in late June and again in November. 

According to astronomers such as Dr. Victor Clube, of Oxford University’s Department of Astrophysics, the coming and goings of the Taurid stream should be a source of concern to politicians, planners and anyone who cherishes life on Earth. A ”catastrophist”, Dr. Clube is one of many astronomers who are convinced that Read more…
