Alert!

In just four days Greenland Ice Melt went from 40% to 97% in 2012!

We have an issue we all need to address here! Climate Change is not only real, it is a threat to our Civilization as we know it!

Green Report – Frightening News – Greenland’s Ice Sheet

NASA scientists were left stunned after analyzing data showing that Greenland’s ice sheet is melting at an unprecedented rate. Three independent satellites confirmed that over four days, the amount of ice melting in Greenland jumped from 40% to 97% – showed by this chart – the image on the left is from july 8 and the image on right is from July 12th. As one NASA scientist wrote in a press release, “This was so extraordinary that at first I questioned the result: Was this real or was it due to a data error?” Unfortunately, it’s very much real – and in 30 years of observations, never has this much ice melted away from Greenland so fast. Of course – oil industry funded scientists will tell us everything is just fine – and it’s just a really hot summer. Meanwhile, they’re the ones most likely looking for mountaintop real estate – away from soon-to-be rising oceans.

being the way they are, not enough will be done, now. Even if we did severe things, it wouldn't stop what's happening.

However if there is anything that we can try.I would like to see it done.

I have no children of my own to pass my world to.However I have nieces and nephews that I adore. I want them to have a good environment in which to live.
We all need to keep trying to educate and move people forward on this issue.
Peace.

I've seen decades go by with a little thing done here, a little thing done there, and always the money wins.

I remember hearing warnings about mercury in the oceans. Bah humbug! the skeptics said. And now, mercury is in the fish. Nothing can be done about it. Women are warned by th egovt not to eat tuna at all, and the rest of us are not to eat tuna and other kinds of fish more than 3 times a week, because of the mercury content.

Anderson Cooper was tested on CNN for certain toxins in his system. He's a healthy guy, lives a healthy lifestyle. He had a high level of mercury or lead or something. The dr. guessed it was from the Hudson River fish, since Cooper lives and eats in NY. Once there, it's there to stay.

Still, I continue to try to be green and speak about it, when it comes up. More and more people agree, but money is what counts to most people. They see the environment and global warming as some vague thing.

I know where you are coming from. All of what u have said is so true! Money$$$$$$ talks however sense walks away. Sigh.
I posted this video re Koch's.


We can still fight them...will we win. I do not know. However we can at least make a stand.

In the end all their money cannot buy them a longer life. They are breathing the same polluted air that they have bestowed on us. They eat the same polluted food that they have given us!
Peace.

For several days this month, Greenland's surface ice cover melted over a larger area than at any time in more than 30 years of satellite observations. Nearly the entire ice cover of Greenland, from its thin, low-lying coastal edges to its two-mile-thick center, experienced some degree of melting at its surface, according to measurements from three independent satellites analyzed by NASA and university scientists.

On average in the summer, about half of the surface of Greenland's ice sheet naturally melts. At high elevations, most of that melt water quickly refreezes in place. Near the coast, some of the melt water is retained by the ice sheet and the rest is lost to the ocean. But this year the extent of ice melting at or near the surface jumped dramatically. According to satellite data, an estimated 97 percent of the ice sheet surface thawed at some point in mid-July.

Researchers have not yet determined whether this extensive melt event will affect the overall volume of ice loss this summer and contribute to sea level rise.

"The Greenland ice sheet is a vast area with a varied history of change. This event, combined with other natural but uncommon phenomena, such as the large calving event last week on Petermann Glacier, are part of a complex story," said Tom Wagner, NASA's cryosphere program manager in Washington. "Satellite observations are helping us understand how events like these may relate to one another as well as to the broader climate system."

mentioned in my previous post. It's all part of the whole picture.

The Petermann Glacier grinds and slides toward the sea along the northwestern coast of Greenland, terminating in a giant floating ice tongue. Like other glaciers that end in the ocean, Petermann periodically calves icebergs. A massive iceberg, or ice island, broke off of the Petermann Glacier in 2010. Nearly two years later, another chunk of ice has broken free.

The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite observed the new iceberg calving and drifting downstream on July 16–17, 2012. Because Aqua is a polar-orbiting satellite, it makes multiple passes over the Polar Regions each day. At 10:25 Coordinated Universal Time (UTC) on July 16 (top image), the iceberg was still close to the glacier. At 12:00 UTC that same day (middle), the berg had started moving northward down the fjord. Thin clouds partially obscure the downstream view.

One day later, at 09:30 UTC on July 17, Aqua spied a larger opening between the glacier and the iceberg, as well as some breakup of the thinner, downstream ice. The iceberg appears to have made a slight counter-clockwise turn. “The floating extension is breaking apart,” said Eric Rignot of NASA's Jet Propulsion Laboratory and the University of California–Irvine. “It is not a collapse but it is certainly a significant event.”

Konrad Steffen, director of the Swiss Federal Institute for Forest, Snow, and Landscape Research WSL, estimated that this iceberg was roughly half the size of the ice island that calved off of Petermann in 2010.

Ted Scambos, lead scientist at the U.S. National Snow and Ice Data Center, noted that this calving event marks a retreat of the Petermann Glacier “farther back than historical calving fronts.” A comparison of this event to the 2010 event shows that this iceberg broke off the glacier tongue farther upstream. The crack along the southern margin of this new iceberg, however, has been visible in satellite imagery for several years. That rift was first identified in 2001.
