Global Warming / Climate Change - Fact not Fiction
« on: March 10, 2012, 09:15:51 PM »

Evidence continues to mount that Climate change is real and the naysayers are being awfully quiet.

Great Lakes ice coverage falls 71 percent over 40 years, researcher says



Great Lakes ice coverage declined an average of 71 percent over the past 40 years, according to a report from the American Meteorological Society.

The amount of decline varies year to year and lake to lake, according to the report's lead researcher, Jia Wang, an ice research climatologist at the National Oceanic and Atmospheric Administration's Great Lakes Environmental Research Laboratory in Ann Arbor, Mich.

Wang’s report said that based on Coast Guard scanning, satellite photos and other research from 1973 to 2010, ice coverage dropped most on Lake Ontario, 88 percent; the second-largest loss was on Lake Superior, at 79 percent.

The smallest decline, 37 percent, was on Lake St. Clair, a lake between Lakes Erie and Huron that was also included in the study.

The study doesn’t include the current winter, but satellite photos show that only about 5 percent of Great Lakes surface froze over this winter, the Detroit Free Press said. That’s down from years such as 1979, when there was as much as 94 percent ice coverage. On average, about 40 percent of the surfaces freeze over, the newspaper said.

Wang told WBEZ-FM in Chicago that diminished ice coverage speeds wintertime evaporation, reducing the lakes’ water levels, which can spur increased and early algae blooms, damage water quality, and accelerate erosion as more shoreline is exposed to waves.

Wang told the Cleveland Plain Dealer newspaper that natural climatic variables such as El Nino, La Nina play as much a role in the ice decline as a warming global climate.

"We are seeing the impact of global warming here in the Great Lakes -- but the natural variability is at least as large a factor," Wang said.

Wang said global climate change and regional climate patterns are competing over the Great Lakes.

The Great Lakes, scientists say, contain about 20 percent of the world's fresh water supply and cover 94,000 square miles in two countries.

The Sun's output has been increased since 1990's.  Some astronomers predict the Sun's output may decline significantly during Sunspot Cycle No 24.

Climate change is a fact, regardless of how some people feel about it...The information is out there and I'm tired of arguing it's validaty.  The nonbelievers are set in their ways and fear any change they might have to endure in their everyday lives, for whatever reasons and whatever lies they've bought into to back their beliefs.  I fully believe that the people who sell oil and coal are the biggest denouncers of climate change research, for the simple fact they fear the loss of income(in the billions!) that will eventually come when mankind finally accepts the inevitable truth.

If you don't think mankind is f***ing up this planet, you're an idiot... 8*

Keep the fires burning, consume and destroy is the way of man... :-\

The Sun's mass is 332,950 times greater Earth's mass.   It seems logical that if this monstrous mass sends less energy our way that we are likely to notice.

Himalayan glaciers actually GAINING ice, space scans show

Himalayan glaciers actually GAINING ice, space scans show

A new study of survey data gleaned from space has shown a vast region of Himalayan glaciers is actually gaining ice steadily, mystifying climate scientists who had thought the planet's "third pole" to be melting.

The study was carried out by comparing two sets of space data, the first gathered by instruments aboard the space shuttle Endeavour in 2000 and the second by the French SPOT5 satellite in 2008. The results were unequivocal. Across the targeted 5,615km2 region of the Karakorum mountains lying on the Chinese border with India and Pakistan, the glaciers had gained substantial amounts of mass by the time the second survey was carried out. Satellite pictures had previously shown the glaciers there spreading to cover more area, but some climate scientists had argued that they might nonetheless be losing ice by becoming thinner: this has now been disproven.


“This is a solid, high-grade measurement,” glaciologist Graham Cogley commented, reviewing the paper published in Nature Geoscience. The study was led by Julie Gardelle of Grenoble uni in France.

The melting or non-melting of the high Asian glaciers provides key underpinnings to climate models and sea-level forecasts and is thus crucial to the climate-change/global-warming debate. However it's actually very difficult to find out what's happening up in most of the valleys of the "third pole", as they are extremely hostile and inaccessible environments. This has led in recent years to attempts to get a proper handle on the situation using space surveys. As in this case, some of these new improved measurements have provided surprising results: a recent survey by the GRACE [Gravity Recovery and Climate Experiment] satellites showed that overall the third pole appears not to be losing any mass at all.

The new discoveries are in sharp contrast to the general narrative until recent times, which had assumed that the Asian glaciers were melting away rapidly. As recently as 2007 the Intergovernmental Panel on Climate Change formally predicted that all the Himalayan glaciers would be gone by 2035: this was later found to be based on a bogus study issued by the hard-green campaigning group WWF. The IPCC retracted the claim, but stuck to its assertion that rapid melting is taking place.

This area has been getting an increased amount of perception, more snow could explane an advance in this glacier. While glaciers elsewhere are still on a rapid decline... :-\

As ice cap melts, militaries vie for Arctic edge
« Reply #7 on: April 16, 2012, 01:33:09 PM »

YOKOSUKA, Japan (AP) - To the world's military leaders, the debate over climate change is ong over. They are preparing for a new kind of Cold War in the Arctic, anticipating that rising temperatures there will open up a treasure trove of resources, long-dreamed-of sea lanes and a slew of potential conflicts. By Arctic standards, the region is already buzzing with military activity, and experts believe that will increase significantly in the years ahead.

 Last month, Norway wrapped up one of the largest Arctic maneuvers ever - Exercise Cold Response - with 16,300 troops from 14 countries training on the ice for everything from high intensity warfare to terror threats. Attesting to the harsh conditions, five Norwegian troops were killed when their C-130 Hercules aircraft crashed near the summit of Kebnekaise, Sweden's highest mountain.

 The U.S., Canada and Denmark held major exercises two months ago, and in an unprecedented move, the military chiefs of the eight main Arctic powers - Canada, the U.S., Russia, Iceland, Denmark, Sweden, Norway and Finland - gathered at a Canadian military base last week to specifically discuss regional security issues. None of this means a shooting war is likely at the North Pole any time soon. But as the number of workers and ships increases in the High North to exploit oil and gas reserves, so will the need for policing, border patrols and - if push comes to shove- military muscle to enforce rival claims.

The U.S. Geological Survey estimates that 13 percent of the world's undiscovered oil and 30 percent of its untapped natural gas is in the Arctic. Shipping lanes could be regularly open across the Arctic by 2030 as rising temperatures continue to melt the sea ice, according to a National Research Council analysis commissioned by the U.S. Navy last year.

 What countries should do about climate change remains a heated political debate. But that has not stopped north-looking militaries from moving ahead with strategies that assume current trends will continue Russia, Canada and the United States have the biggest stakes in the Arctic. With its military budget stretched thin by Iraq, Afghanistan and more pressing issues elsewhere, the United States has been something of a reluctant northern power, though its nuclear-powered submarine fleet, which can navigate for months underwater and below the ice cap, remains second to none. Russia - one-third of which lies within the Arctic Circle - has been the most aggressive in establishing itself as the emerging region's superpower Rob Huebert, an associate political science professor at the University of Calgary in Canada said Russia has recovered enough from its economic troubles of the 1990s to significantly rebuild its Arctic military capabilities, which were a key to the overall Cold War strategy of the Soviet Union, and has increased its bomber patrols and submarine activity. He said that has in turn led other Arctic countries - Norway, Denmark and Canada - to resume regional military exercises that they had abandoned or cut back on after the Soviet collapse. Even non-Arctic nations such as France have expressed interest in deploying their militaries to the Arctic.

"We have an entire ocean region that had previously been closed to the world now opening up," Huebert said. "There are numerous factors now coming together that are mutually reinforcing themselves, causing a buildup of military capabilities in the region. This is only going to increase as time goes on." Noting that the Arctic is warming twice as fast as the rest of the globe, the U.S. Navy in 2009 announced a beefed-up Arctic Roadmap by its own task force on climate change that called for a three-stage strategy to increase readiness, build cooperative relations with Arctic nations and identify areas of potential conflict, "We want to maintain our edge up there," said Cmdr. Ian Johnson, the captain of the USS Connecticut, which is one of the U.S Navy's most Arctic-capable nuclear submarines and was deployed to the North Pole last year. "Our interest in the Arctic has never really waned. It remains very important."

 But the U.S. remains ill-equipped for large-scale Arctic missions, according to a simulation conducted by the U.S. Naval War College. A summary released last month found the Navy is "inadequately prepared to conduct sustained maritime operations in the Arctic" because it acks ships able to operate in or near Arctic ice, support facilities and adequate communications "The findings indicate the Navy is entering a new realm in the Arctic," said Walter Berbrick a War College professor who participated in the simulation. "Instead of other nations relying on the U.S. Navy for capabilities and resources, sustained operations in the Arctic region will require the Navy to rely on other nations for capabilities and resources."

He added that although the U.S. nuclear submarine fleet is a major asset, the Navy has severe gaps elsewhere - it doesn't have any icebreakers, for example. The only one in operation belongs to the Coast Guard. The U.S. is currently mulling whether to add more icebreakers. Acknowledging the need to keep apace in the Arctic, the United States is pouring funds into figuring out what climate change wil bring, and has been working closely with the scientific community to calibrate its response."The Navy seems to be very on board regarding the reality of climate change and the especially large changes we are seeing in the Arctic," said Mark C. Serreze, director of the National Snow and Ice Data Center at the Cooperative Institute for Research in Environmental Sciences University of Colorado. "There is already considerable collaboration between the Navy and civilian scientists and I see this collaboration growing in the future." The most immediate challenge may not be war - both military and commercial assets are sparse enough to give all countries elbow room for a while - but whether militaries can respond to a disaster Heather Conley, director of the Europe program at the London-based Center for Strategic and International Studies, said militaries probably will have to rescue their own citizens in the Arctic before any confrontations arise there "Catastrophic events, like a cruise ship suddenly sinking or an environmental accident related to the region's oil and gas exploration, would have a profound impact in the Arctic," she said. "The risk is not militarization; it is the lack of capabilities while economic development and human activity dramatically increases that is the real risk."
