Ice Shelf
news.bbc.co.uk

A prominent Antarctic scientist says a large ice shelf is disintegrating much faster than he predicted. In fact, it’s “hanging by a thread,” according to David Vaughan of the British Antarctic Survey. The concern over melting ice shelves has to do with the tremendous amount of water they store. The more they melt, the more sea level rises.

BBC:

Professor David Vaughan of BAS said: “Wilkins is the largest ice shelf on the Antarctic Peninsula yet to be threatened.

“I didn’t expect to see things happen this quickly. The ice shelf is hanging by a thread - we’ll know in the next few days or weeks what its fate will be.”

Sounds like we need a scientist, not another lawyer.

OK, us nuts and the overwhelming majority of weather scientists will go think on our own. And you un-nuts and your factoids are welcome to have a big superconference together!

On page 5… Summary:  Thanks to global warming, the Arctic icecap is rapidly melting, opening up access to massive natural resources and creating shipping shortcuts that could save billions of dollars a year. But there are currently no clear rules governing this economically and strategically vital region. Unless Washington leads the way toward a multilateral diplomatic solution, the Arctic could descend into armed conflict.

Pity that the idiots in control still can’t see beyond their pathetic shouting and screaming at each other (like so many monkeys in a tree, uhh).

Its no longer about dollars or trade or possession of resources, its about survival of the most precious species known to mankind - itself!!!

Amen!Amen!Amen!Amen!
Hardly ever hear mention of the effects that 6.5 billion people have on our planet. I guess because human life is so sacred that even talking about the subject is frowned upon which maybe money is the only thing more important. But the inescapable truth is that all the current problems world wide are the direct affect that 6.5 billion people have on a smaller and smaller planet. I have seen projections that by 2030 or so it will be up to 10 billion or so. I think this is short, I would say 20 to 25 billion.
In this ‘modern’ world it would be likely I would still be alive by then but I think just the health problems will prevent that which may just be the better thing.
Well, just some numbers, I think I will go to bed and think about something more positive, like will I be able to get out of bed in the morning.

Given the subject, thought this might be of interest:

Carbon sequestration or CO2 capture is not only cost and energy expensive in piping it 100’s of miles, Guitarsandmore805, but it involves injecting tons of liquified CO2 underground with unknown and unknowable geological consequences.

Apart from the local geological hazards (earthquakes), it may (a) leak back out into the atmosphere, or more likely (b) leach into underground water contaminating artesian basins and the water table with Carbonic acid as the CO2 mixes with the water.

There are so many more examples of ice sheets increasing in size.  The Antarctic shelf has been melting for over 6,000 years, hardly a result of man-made warming.  The ice in Greenland and Canada has increased dramatically.  Even the polar bears are increasing in number, in 10 of the 11 distinct populations that exist.

Blah, blah, blah.  When will you people do some thinking on your own.

Between climate change, peak oil, a global economic meltdown and continued (and possibly increasing) global terrorism, I’d say we’re all going to hell in a handbasket, so we should simply enjoy the ride…

Peace.

Present policies, with continued construction of coal-fired power plants without CO2 capture, suggest that decision-makers do not appreciate the gravity of the situation. [Note to Hansen et al: That is the understatement of the year.] We must begin to move now toward the era beyond fossil fuels. Continued growth of greenhouse gas emissions, for just another decade, practically eliminates the possibility of near-term return of atmospheric composition beneath the tipping level for catastrophic effects.

Quote Wiki: An ice shelf is a thick, floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface. Ice shelves are found in Antarctica, Greenland and Canada only.

The boundary between the floating ice shelf and the grounded resting on bedrock ice that feeds it is called the grounding line. When the grounding line retreats inland, water is added to the ocean and sea level rises.... http://en.wikipedia.org/wiki/Ice_shelf

Ice shelves don’t “float” while they are still attaced to the main ice mass on land, John. They are sitting on the coastal shore seabed. Thus they WILL add significantly to the water level eventually when melting, uhh.

Melting ice shelves do not raise the level of the sea.  Ice shelves are floating in the sea.  When they melt they just fill with water the same volume they were already displacing in the water.  The actual article says the important aspect of the melting ice shelves is that they indicate warming.  It does not make the mistaken claim that melting ice shelves raise sea levels.

Your moronic subeditor described this article as pointing to a problem with rising sea levels. To quote the article:
“Since an ice shelf is a floating platform of ice, the break-up will have no impact on sea level.”
The problem getting people to accept the science is bad enough without having hacks mess up like this.

The best hard core evidence that I can throw back at the ‘save the economy’ non-believers of global warming is that the glaciers are melting and receding and that the ice caps are melting and breaking apart. I still get scoffed at. I don’t care because I am at least aware of the some of the effects of global warming and have a good idea of other issues that will SLOWLY crop up on the planet due to its affects.
What I don’t see and expect not to see because the MSM is definitely not going to put this information out, not just because all the proof is not out there or it is being hidden, is the effects of all the pollution that is SLOWLY creating more and more health crises around the would and for the sake of money the pollution cannot be brought under regulations.
And what I do know is that with 6.5 billion people hoggishly slopping down more and more natural resources that their contribution to the issues of global warming and pollution is NOT negligible.
So, have a good clean breath of fresh air and a clean cool refreshing drink of pure water and a great nutritionally fresh meal from nature.
