As global warming melts the world's ice sheets, rising sea levels are not the only danger. Viruses hidden for thousands of years may thaw and escape - and we will have no resistance to them.
Last week, the latest study to track global warming revealed that Alaska's snowless season is lengthening. As the world warms and ice-sheets and glaciers begin to melt, most of us worry about how the earth will respond and what kind of impact climate change will have. Will flooding become a regular feature, or is the land going to become parched? Are hurricanes and typhoons going to spring up in places they have never visited before? Is the rising sea level going to swallow some of the world's most fertile farmland, along with millions of homes?
All of these are valid concerns, but now it turns out that the impact of global warming could be worse than we first imagined. Ice sheets are mostly frozen water, but during the freezing process they can also incorporate organisms such as fungi, bacteria and viruses. Some scientists believe that climate change could unleash ancient illnesses as ice sheets drip away and bacteria and viruses defrost. Illnesses we thought we had eradicated, like polio, could reappear, while common viruses like human influenza could have a devastating effect if melting glaciers release a bygone strain to which we have no resistance. What is more, new species unknown to science may re-emerge. And it is not just humans who are at risk: animals, plants and marine creatures could also suffer as ancient microbes thaw out.
In 1999, Scott Rogers from Bowling Green State University in Ohio and his colleagues reported finding the tomato mosaic tobamovirus (ToMV) in 17 different ice-core sections at two locations deep inside the Greenland ice pack. Gentle defrosting in the lab revealed that this common plant pathogen had survived being entombed in ice for 140,000 years. "ToMV belongs to a family of viruses with a particularly tough protein coat, which helps it to survive in these extreme environments," says Rogers.
Since then Rogers has found many other microbes in ice samples from Greenland, Antarctica, and Siberia. And this has turned out to be just the tip of the microbial iceberg. Over the last 10 years biologists have discovered bacteria, fungi, viruses, algae and yeast hibernating under as much as 4km of solid ice, in locations all over the world.

Exactly....These "There is no global warming" proponents never come up with information that is not politically motivated.
Data from the National Centers for Environmental Prediction, Boulder, Colo., suggest that winds pushed perennial ice from the East to the West Arctic Ocean (primarily located above North America) and significantly moved ice out of the Fram Strait, an area located between Greenland and Spitsbergen, Norway. This movement of ice out of the Arctic is a different mechanism for ice shrinkage than the melting of Arctic sea ice, but it produces the same results - a reduction in the amount of perennial Arctic sea ice.
What good is having a job if the air you breathe is not healthy?
What good are vehicles if you can't drive them because of massive flooding due to polar ice caps melting?
What good are nice houses if the land you live on cannot grow food?
Answer those questions and we will proceed from there with your argument.

Thing is, it will be difficult to convince anyone to spend money solving a problem that will not directly effect them, but only future generations. This is why such a finding isn't doing much more than raising some eyebrows....
Culture of Indifference Leaves America Open to BSE
Suzanne Goldenberg talks to insiders who warn of failings in a lax inspection regime
by Suzanne Goldenberg
When the first case of mad cow disease was diagnosed in America a caustic joke began the rounds of the vets and food inspectors who monitor safety standards at the meat packing plants.
It was no surprise, it went, that a sick animal had been brought to the slaughter, but it was absolutely shocking that the discovery had ever become public.
"That's the point where something went wrong with the system - that it became public," a manager with nearly 30 years' service in the agriculture department's food safety and inspection service told the Guardian.
"Among ourselves, we think our inspection system is the lowest in the world."
The senior safety source and others with an inside view of the US meat industry questioned by the Guardian describe a culture of indifference towards the threat of BSE.
In the slaughterhouses and meat packing plants, vets and food safety inspectors say:
policies favor the beef industry at the expense of consumer safety;
testing for BSE is rare and haphazard, and carried out by people with minimal training in the disorder;
discussion of the disease by regulators was discouraged;
government agencies fail to enforce their own safety standards.
Global Warming Basics
www.pewclimate.org...
The scientific community has reached a strong consensus regarding the science of global climate change. The world is undoubtedly warming. This warming is largely the result of emissions of carbon dioxide and other greenhouse gases from human activities including industrial processes, fossil fuel combustion, and changes in land use, such as deforestation. Continuation of historical trends of greenhouse gas emissions will result in additional warming over the 21st century, with current projections of a global increase of 2.5ºF to 10.4ºF by 2100, with warming in the U.S. expected to be even higher. This warming will have real consequences for the United States and the world, for with that warming will also come additional sea-level rise that will gradually inundate coastal areas, changes in precipitation patterns, increased risk of droughts and floods, threats to biodiversity, and a number of potential challenges for public health.
Addressing climate change is no simple task. To protect ourselves, our economy, and our land from the adverse effects of climate change, we must ultimately dramatically reduce emissions of carbon dioxide and other greenhouse gases. To achieve this goal we must fundamentally transform the way we power our global economy, shifting away from a century’s legacy of unrestrained fossil fuel use and its associated emissions in pursuit of more efficient and renewable sources of energy. Such a transformation will require society to engage in a concerted effort, over the near and long-term, to seek out opportunities and design actions to reduce greenhouse gas emissions.
How significant is this warming? The earth's temperature has always fluctuated, but ordinarily these shifts occur over the course of centuries or millennia, not decades. The 1990s were the hottest decade of the entire millennium.
Let's turn now to a third myth: There's so much uncertainty - about the science, about the economics - that we need to wait for better information before we can decide how to respond. The reality is that there are several very compelling reasons that we must begin to act right now - and uncertainty itself is one of them.

Its all part of the cycle. The Ozone is now almost completely healed back up after banning CFCs.
Seriously folks. There is no proof at all that we are "causing a global warming epidemic". Just more fear mongering.

Therein lies the problem with America today. Peple are so shortsighted, as you so eloquently described me, that they don't realize how politics,religion,world events, are going to affect them 5-10 years down the road. You see, Americans have this mindset, "If it doesn't affect me immediately, I am not worried about it." Now, Gazrok, that's shortsighted and pretty stupid to boot.

Or another possibility is that, unlike you, a majority of Americans are convinced that the current warming trend is part of a natural cycle, and that nothing they do or could do would have much of an effect. And that all the economic restrictions people like Al Gore want to put on the U.S. would end up hurting the country for no good reason.

Here they are again> What good is having a job if the air you breathe is not healthy? What good are vehicles if you can't drive them because of massive flooding due to polar ice caps melting? What good are nice houses if the land you live on cannot grow food?

What good is it asking a question based on a false premise? What good is it asking questions which are overexaggerated hyperbole? How does awnsering a question which is in truth nothing more than an exaggerated strawman argument in any way shape or form constructive?

Answer those questions and we will proceed from there with your argument.
1) A job creates a service which is rewarded by some compensation (generally monetary in nature). Money can then be used to pay for healthcare to alleviate the effects of unhealthy air.
2)This question assumes that polar melting will cover all land in which case I suggest using a boat.
3)Houses still provide much needed protection from the elements. I'll be honest, I do not have a green thumb and have never been the best at raising crops, but there have been some pretty cool advances in hydroponics and you can create pretty good planting soil through composting.
Basically, all three of the above questions can be answered by stating man's one true purpose in life: the quest to impress women. Women like a guy with a job, nice car (or boat depending on the situation), and a house, so that they can through the trade of sex, they can influence why men make money, what vehicle they drive, and what kind of place they live in.
Just thought I'd answer the 3 questions.
It's not good, but tell that to the welders who work in a nastier environment than you've thought about. They do it to raise their kids out of that mess, and because they don't have to get into a buttload of debt to work there (via college). Imporve the situation that puts them in such jobs, and then you've got room to do some things.

We've seen a lot of melting, and I still don't see the water rising down here, sha. Where's de proof dat de water is rising? An unusual ammount of water has melted, so where did it go, if not to flood my coastal back yard, hmm?
What good are vehicles if you can't drive them because of massive flooding due to polar ice caps melting?
I grow food in pots of human treated soil. I can't grow food under my house's foundation, and I'm glad I can't, the roots break the foundation, thankyou.
What good are nice houses if the land you live on cannot grow food?
Walk up to any number of individuals and show them a picture of Dick Cheney and see if they can tell you who he is. I lay you odds,matter fact, I already know this to be true because there have already been surveys like this done, that sixty to seventy percent of the people don't know who he is.That is how out of touch Americans are. They think he's a freakin movie actor or something silly like that.
You can't tell me that people in Tokyo or Paris are that uninformed and make me believe it. However, they are certainly that uninformed in American cities such as New York, Boston,Houston and Los Angeles....There is research to back that up...so...

This, however, does not mean that we should not do what we can to help the environment, but for our sakes, not for the planets sake.
The problem with what you said is that everything is interconnected. If the planet doesn't exist,then we surely do not. So, if we do it, it will have to begin as a project for the planet's sake.
