Global Warming?

So much for 'settled science'

According to the U. S. National Climatic Data Center, the average temperature of the global land surface in January 2008 was below the 20th-Century mean for the first time since 1982.

 

Also in January, Southern Hemisphere sea ice coverage was at its greatest summer level (January is summer in the Southern Hemisphere) in the past 30 years.

 

Neither the 3,000 temperature buoys that float throughout the world's oceans nor the eight NASA satellites that float above our atmosphere have recorded appreciable warming in the past six to eight years.

 

Even Rajendra Pachauri, the head of the IPCC, reluctantly admitted to Reuters in January that there has been no warming so far in the 21st Century.

So how come they want to put the Polar Bear on the endangered spices list do to receding ice? I mean somethings going on.

Glaciers and Glacial Warming Globally

 

I remember as a kid I walked on Portage Glacier. Now you need binoculars to see it.

Another theory

 

The Portage Glacier, in south-central Alaska, is viewed by thousands of visitors annually who come to the U.S. Forest Service Begich, Boggs Visitor Center located on the road system between Anchorage and Whittier, Alaska. During the past century, the terminus of the glacier has retreated nearly 5 kilometers to its present location (fig. 1). Like other glaciers that terminate in water, such as Columbia Glacier near Valdez or Mendenhall Glacier near Juneau, Portage Glacier has experienced accelerated retreats in recent decades that likely were initially triggered by climate change begun at the end of the Little Ice Age in the mid-1800s and subsequently controlled in recent history primarily by calving of the glacier terminus. Photographic records of the terminus covering 1914 until present day track the patterns of retreat. These data, coupled with USGS climate information collected from the southern end of the ice field, provide insight to the patterns of retreat that might be observed in the future.

 

History

During the late 1800s and early 1900s, Portage Glacier terminated on land at the western end of Portage Lake, filling Portage Lake with ice (Photo Plate 1914). Since the early 1900s, the glacier has receded, leaving Portage Lake in the scoured basin. The initial retreat of the glacier coincides with known climate warming associated with the end of the Little Ice Age (circa mid-19th century). As the glacier receded, its land-based terminus retreated into proglacial Portage Lake and changed from its relatively stable land-based environment to an unstable calving environment. The most rapid recession of some 140 to 160 meters per year occurred between 1939 (Photo Plate, 1939) and 1950, when water depth at the terminus was at its maximum—roughly 200 meters. Recession continued through the 1970s and 1980s (Photo Plate, 1972, 1984) until by late 1999, Portage Glacier had receded almost 5 kilometers, to a more stable position at the eastern end of Portage Lake (Photo Plate, 1999). The retreat was driven primarily by calving of unstable ice at the glacier terminus into Portage Lake. Ice loss resulting from increased melting of the glacier surface during the past century-long general warming trend contributed to glacier retreat, but to a lesser extent. Today, the terminus of Portage Glacier remains close to its 1999 location (Photo Plate, 2006).

 

 

Future Status

Future changes of the terminus of Portage Glacier will depend on a variety of factors. However, present scientific theory (Meier and Post, 1987, Trabant and others, 2003) suggests that calving glaciers cycle between advance and retreat patterns; with rapid retreats, followed by stable retracted positions, slow advances, and then stable extended positions that are not directly related to climate change. Thus, based on its history to date, and if such a pattern holds for Portage Glacier, the glacier may now be in its stable retracted position and could eventually begin a slow advance. However, for a glacier to advance, annual net balance—the amount of new snow and ice added to the glacier minus the amount of glacier melt—must be positive. As a rule of thumb for valley glaciers, net balance is positive when annual snow and ice accumulation occurs over more than 60–70 percent of the entire glacier area. Such accumulation occurs on the glacier above the end-of-summer snow-line altitude, recently measured by USGS at 1,000 meters in altitude. Only 50 percent (not the rule-of-thumb 60–70 percent) of Portage Glacier is more than 1,000 meters in altitude, thus, Portage Glacier may slowly thin and recede rather than experience a slow advance.

 

Regardless of predictions, the position of the Portage Glacier terminus has remained relatively unchanged at the eastern end of Portage Lake for the last 7 years and continues to provide visitors with a spectacular view of glacier ice.

 

There are approximately 5 times as many polar bears now as compared to 1950. Polar bears eat people. Don't need too many of them.

Yeah.. well says you.

So how come they want to put the Polar Bear on the endangered spices list do to receding ice? I mean somethings going on.

 

It's a back door tactic to prevent any expansion on oil drilling in Alaska. There are currently around 25,000 polar bears. That is about 3 1/2 times as many polar bears as there was in 1972. Doesn't sound like a species that's endangered to me.

The future according to Al? Someday no matter what we do...

AHHHHHHHHHHHHHHH!!! GLOBAL FREEZING!!! EVERYONE GO BUY AN ESSUUVEE!!! SWITCH FROM FLORESCENT BULBS OR WE ARE GOING TO FREEZE TO DEATH!!!

In Baldwin Park, a San Gabriel Valley suburb east of Los Angeles, children donned yellow kitchen gloves as they threw snowballs at each other. Others squealed with delight as they used boogie boards to slide across lawns and sidewalks buried inches deep in hail.

Global warming is the brainchild of the failed communists of the 60's who became "environmentalists" in the 80's.

Have you ever had a polar bear steak? A lot more tender than one would think.

Ted Poe is one of the few decent congressmen. Liberals in Harris County hate him since his days as a no nonsense judge.
