Carbon Levels Are Critical

Carbon amounts in the atmosphere ar already at 385 ppm, whereas their maximum levels are at 350 ppm

Past studies argued that the maximum amount of carbon that our atmosphere could handle was somewhere around 450 ppm (parts per million). However, this is an extremely wrong assessment, argue the supporters of a new theory, which states that a maximum of 350 ppm is sufficient to trigger significant changes in our planet's life-sustaining equilibrium.

 

An international research team, featuring scientists from the United States, the United Kingdom and France, have found that atmospheric CO2 is already at 385 ppm, and constantly rising by about 2 ppm each year. The main culprit for this increase is the burning of fossil fuels to generate electricity. Coal, oil, and natural gases are responsible for the enormous amounts of carbon emitted into the air worldwide.

 

“This work and other recent publications suggest that we have reached CO2 levels that compromise the stability of the polar ice sheet. How fast ice sheets and sea level will respond are still poorly understood, but given the potential size of the disaster, I think it’s best not to learn this lesson firsthand,” warned Yale professor of geology and geophysics Mark Pagani, who is also one of the authors of the current study detailing the new theory.

 

A potential solution to this problem could be the complete phase-out of coal and oil by 2030, the authors say. This would lead to CO2 levels reaching a peak of 400-425 ppm, after which they would slowly begin to decline. However, it's highly unlikely for this to happen, especially considering that some countries are just now finding out about large reserves of fossil fuels on their territories.

 

“[By] following a path that leads to a lower CO2 amount, we can alleviate a number of problems that had begun to seem inevitable, such as increased storm intensities, expanded desertification, loss of coral reefs, and loss of mountain glaciers that supply fresh water to hundreds of millions of people,” said lead study author James Hansen, from the Columbia University.

 

The new finding raises many concerns about the future of our civilization, and to whether or not our atmosphere will be able to sustain life for much longer. Undoubtedly, critics of this new study will say that the results are wrong or faked. But the fact of the matter is that urgent action needs to be taken immediately, so as to prevent a global catastrophe.

JUNK SCIENCE!
This article is biased, completely wrong, and tries to play on your fears of the unknown by spreading lies, half-truths, and misinformation. It is a betrayal of scientific and journalistic ethics and standards. Where in this article is scientific neutrality, honest inquiry, or alternate viewpoints? Where is there a mention of the major disagreements with this science-fiction fantasy?

Where is there a mention that we've been in a COOLING TREND for the last 10 YEARS?

'Well, James Hansen said it's so, so it MUST be true!'
No, it isn't. James Hansen has been thoroughly discredited. He is promoting junk science.
There are a large group of 'scientists', politicians, and media promoting lies that scare the hell out of the public, all with the aim of getting financial gain and political power. But large numbers of people repeating the same lies over and over doesn't make something true. (By the way, higher carbon dioxide levels are a PRODUCT of higher temperatures, not a cause of them.)

Notice that there is never any reference to the large numbers of scientists who DISagree with this bizarre theory.
Notice that most of the leaders of this nutty movement, like Al Gore, and the idiot celebrities - live an elitist, luxurious lifestyle with private jets, SUVs, chauffer-driven limousines, 20,000 square foot homes. Apparently their rules for a reduction in our standard of living only apply to the ordinary working stiffs, not to them.

Try reading a little common sense for a change.

"higher carbon dioxide levels are a PRODUCT of higher temperatures, not a cause of them"

and higher temperatures occur, let me guess, from the natural cycles Earth undergoes regularly, right? it's not like billions of tones of carbon emitted each year have the slightest effect on our atmosphere. and the ozone hole above Antarctica, which allows for radiation to pass unto the planet, is also made naturally, because we are on a warming trend and it's only natural for this to happen. Well, no, that's not the case.

"No, it isn't. James Hansen has been thoroughly discredited"

and who discredited him? The fact that some people say that he is promoting junk science doesn't make it true.

Maybe you, personally, think there is a "clique" of dark individuals, whose sole purpose is to rule the world. I prefer to look at the facts, and the facts are simple. More carbon CAUSES heat, with the exception of tundra soils, which release more carbon as warming occurs. But that's a vicious circle, as the process was jumpstarted by carbon emitted from the burning of fossil fuel.

If you like these sites and think they are a good read, go ahead and read them. But to the stack of sites explaining global warming and carbon levels comprehensively, surely not all are run by Al Gore and other "lunatics". Please explain, in your own words, how is it that polar caps are growing, when Larsen A and B have sunk in the Antarctic in the last 10 years. And how is it that dead water keeps slowing down boats in the Northern Atlantic? Surely, because ice caps are growing. I think NOT.

And btw, Al Gore gets all the criticism because he is a former US presidential candidate that never got office because of what he believed. I am not saying he is an environment guru, and I don't disagree, he and other celebrities have mansions and SUVs and whatnot. But I don't, and I also don't let other people tell me that what i believe is wrong, based on 3 web sites and a big mouth.

The science that predicates many of the claims regarding Global Warming is pretty basic. It is science fact that there are substances called greenhouse gases that trap the sun's energy, providing temperatures that are hospitable for life on Earth. It is also science fact that an increase in these gases increases the greenhouse effect, which can have dire results.

Climate is not the same as weather. Climate is by definition a long-term trend, and no one knows how climate will be affected by increased greenhouse gases. For all we know, it could be preventing the next ice age. Climate is extremely complex, so all we can really do is conjecture based on the science we do know.

Science should be questioned and challenged, but it should be questioned and challenged with science, not opinion or emotion. We should not accept somethign as fact just because experts say it is so. I challenge everyone to do their own research about global warming, and to do it quickly, because if global warming is a real threat, which I personally believe it to be, every individual needs to be informed now. After all, we are the voters that influence the policy that enacts change.

What is at stake is literally the fate of human civilization as we know it. With stakes those high, I think it pays to do your own research with credible sources! Articles like this, hopefully, will prompt people to do just that!
