To meet climate goal, only quarter of fossil fuels can be used: study

Apr 29, 2009
Activists hold signs as they participate in a rally on the West Lawn of the US Capitol in March 2009 in Washington, DC. Meeting a widely-supported goal to tackle global warming means that humanity will be able to burn less than a quarter of the proven reserves of fossil fuels by 2050, a study released on Wednesday said.

Meeting a widely-supported goal to tackle global warming means that humanity will be able to burn less than a quarter of the proven reserves of fossil fuels by 2050, a study released on Wednesday said.

The paper, published by the British journal Nature, implies only a revolution in can achieve the aim of limiting warming to less than two degrees Celsius (3.8 degrees Fahrenheit) above pre-industrial levels.

To achieve the objective -- embraced by the European Union (EU) and many scientists -- means that only 1,000 billion tonnes of () can be emitted between 2000 and 2050, it said.

By comparison, the world has emitted a third of that amount in just nine years.

"If we continue burning as we do, we will have exhausted the carbon budget in merely 20 years, and global warming will go well beyond two degrees," said the study's lead author, Malte Meinshausen of the Potsdam Institute for Climate Impact Research in Berlin.

Fossil fuels -- , and oil -- provide the backbone of the world's energy supplies.

But they are also the main source of heat-trapping carbon gases blamed for warming Earth's atmosphere and driving changes to weather patterns.

Boosting efficient use of these fuels so that they are no longer dangerous or switching to cleaner alternatives carries an economic cost, and this is the biggest stumbling block in efforts to defuse the threat.

Meinshausen said the change should not be delayed and cautioned that even with a 2 C (3.8 F) warming, there would still be unprecedented risk.

"Only a fast switch away from fossil fuels will give us a reasonable chance to avoid considerable warming," he said in a press release.

"We shouldn't forget that a 2 C [3.8 F] global mean warming would take us far beyond the natural temperature variations that life on Earth has experienced since we humans have been around."

"To keep warming below 2 C [3.8 F], we cannot burn and emit the CO2 from more than a quarter of the economically recoverable fossil fuels up to 2050, and in the end, only a small fraction of all known fossil-fuel reserves," said co-author Bill Hare, also of the Potsdam Institute.

The study said world emissions of greenhouse gases have to be cut by more than 50 percent by 2050 levels compared to 1990 levels if the risk of busting the 2 C (3.6 F) ceiling is to be limited to 25 percent. In addition, reductions would have to be made from 2020.

The Group of Eight (G8) countries have pledged an emissions reduction of at least 50 percent by 2050.

But they have not identified a benchmark year against which this should be measured nor set an intermediate date by which emissions cuts should start.

Negotiations are underway under the UN's Framework Convention on Climate Change (UNFCCC) for agreeing on emissions cuts beyond 2012, when current pledges under the Kyoto Protocol expire. The UNFCCC wants to wrap up a deal in a conference in Copenhagen in December.

The world has already warmed by about 0.8 C (1.44 F) since the start of the Industrial Revolution, and another 0.5 C (O.9 F) or so is considered inevitable over coming decades given past greenhouse gas emissions.

In this article, Malte Meinshausen of the Potsdam Institute for Climate Impact Research in Berlin, said, "We shouldn't forget that a 2 C [3.8 F] global mean warming would take us far beyond the natural temperature variations that life on Earth has experienced since we humans have been around."

In this Wikipedia entry on Homo Sapiens:

"DNA evidence indicates that modern humans originated in east Africa about 200,000 years ago."

And in this article on Nature.com:
http://www.nature...805.html

"Here we present an undisturbed climate record from a North Greenland ice core, which extends back to 123,000 years before the present, within the last interglacial period."

"The oxygen isotopes in the ice imply that climate was stable during the last interglacial period, with temperatures 5 °C warmer than today."


IMAO (In My Arrogant Opinion), doing as this article suggests would drastically depress the world's economy and the growth of civilization and achieve nothing in regards to the climate.

Struggling, underdeveloped nations would continue to suffer, forever barred from exploiting economical power sources. The economies of developed nations would reel under the penalties imposed in the form of carbon taxes.

What they are proposing is pure fantasy, and it will turn into a nightmare if we proceed.

Man made global climate change is a lie.



That said, Mealer American Motors Corp, aka Mealer Companies LLC has an automobile that uses no fossil fuels and is not an EV.



The MEALER will power your home or office, thus making it the ONLY CARBON TAX FREE power system or automobile. To be honest, the first few hundred thousands vehicles will be taxed for the power it takes to build them and deliver them.. But after that we will be off grid and using our own vehicles for delivery.



This is due to the hatred for terrorists and the disdain for greed from the oil companies and not due to some rediculous global climate change trend.



I could cry like the rest of the carpetbaggers and try to cash in on the scare tactic...

But Mealer Companies has a moral backing that keeps honesty above all else. We are ont he same side... Don't fall for this Al Gore BS. It's all about taking your money and sending it elsewhere and into already wealthy people's pockets.



If Gore were on the up and up.. He'd shut down his Nashville, Tennessee mansion that blows more "greenhouse" gases into the atmosphere per year than the entire University of California, Berkeley dorms per six months.



Including all the bong smoke emmissions in those same dorms!

Dude, I am all in favor of capitalism and advertising. So why don't you go buy an ad on this site and stay the hell out of the comment sections.

Your legitimate comments are welcome, but I am sick of seeing your ads passed off as comments.

As for the actual comments interspersed within your ads:

I am happy to trade with all nations, as the interdependence of free trade is the best way to keep everyone on good terms. Once the Middle Eastern contries become dependent, not only on oil revenues, but also on tourism and industry revenues, they will take steps to help curb or abolish terrorism. Do you really think they want a bunch of crazies flying jets into the gigantic towers they are erecting in the gulf region? Some Saudi's are proposing building a ONE MILE TALL building. Maybe they wanna be masters of the world, and then again, maybe they just wanna trade and build their egos up just like many other entrepeneurs.

In addition, I do not consider it greedy to sell a commodity that everyone wants, for whatever price they are willing to pay. If you don't want gasoline, don't buy it.

I'll go along with you on the Al Gore BS.

Now go away! :P

Fazer I can't agree with you on mideastern terrorists suddenly becoming docile with the mideast oil tycoons turned enterpreneurs. The oil tycoons may play the tourism game, but that is doubtful.

Gasoline is a needed product right now and I expect to offer an alternative. It's clean too, so it can be a do all fit all product. I enjoy gasoline powered engines quite a bit... But the current view is to ban them and introduce something new. The EVs can't get the job done.

My "ads" are not advertisements but instead simple notes so people are aware of the coming solutions for problems that we discuss in these posts. The ad campaign will be totally different and professionally done (NOTICE MY TYPOS!?.. An ad would not have typos.. at least I hope not).

I aprreciate you pointing out the monotony of my "ads"... ie comments. I can't go away until I build my company and you are driving a MEALER.

DozerIAm... you don't know how wrong yet how right that statement you made is! So far, there is no fuel cell vehicle that is roadworthy.. BMW has some great vehicles out, but splitting H2O for hydrogen as a fuel is a tough job that requires more work than it is worth. The vapor part of your comment as far as fuel is close to the mark.

Mealer,

Toyota and Honda both have very good Hydrogen powered cars that are demoing in California. You're going to have a very tough time competing with them.

Especially if you're thinking of trying to build an automotive company in the US.

Perhaps I should have typed AS I build my company. We are beyong garage and scouting mfg locations with the help of developers and will be depending on VC money. This economy kicked out our last major funding deal in 2008. The last thing I would want to do is post BS across the web...

I've already been ten rounds with some nutcase telling me he can redistribute sand throughout the world and set up mysterious crystals to reverse what he believed was global warming. Why I even typed back at him is beyond me.. I guess I was bored.

Velanarris,
Hydrogen is fine and as long as we have fueling stations we can use them to get around town.
BMW outdoes Toyota and Honda by a long shot with Hydrogen powered vehicles, they are all very good automakers and I would never turn one down.

The MEALER secret?
MEALER uses mixture of gases and liquids in the form of a "plasma" for no better term.

We have a patented and functioning system with operating software for such a device... this fuel is self-sustaining, and the device causes it to be self-replicating. (for no better term).
Hygrogen cannot touch this product. We will not have a tough time competing with them as the MEALER will provide an electrical power system in the 3 phase, 220v-110v range.

We will be building the MEALER in the USA. The trick is to avoid the mobsters in the UAW and AFL-CIO while providing similar employee benefits without the union execs and lawyers to keep ont he payroll.. and to mainatin CEO paychecks to a reasonable amount.

Seriously, after the first million in the bank and a decent paycheck... What is the purpose of more millions? EXCEPT of course, to begin more businesses and get more people to work.

Now lay off attacking me... I am not your enemy and this bickering against me makes you two sound like liberal democrats or like you're just really angry at life or something.

This being a science minded forum here, I'm sure there are others besides just me being ... doubtful of your claims, especially when you throw terms like "plasma" around, and make what sounds suspiciously like a claim that your device is a perpetual motion machine. Since you have apparently "discovered" a new state of matter and a some form of tabletop energy that is clean, abundant and cheap, one would think you would be satisfied with writing a peer reviewed paper and getting the Nobel Prize for Science, being Man of the Millenium, and in general beign regarded as the greatest mind since Da Vinci.

Unless of course you are just another variation of some nutjob who claims he can redistribute sand throughout the world and set up mysterious crystals to reverse what he believed was global warming.

Aren't we communicating via physorgs email?
Why would you want to continue to knock what I am doing vs what you are not doing?

The comment about the nutjob with the sand and crystals came from me to you originally...

I am only the fourth greatest mind since Da Vinci, you, Al Gore and E.E. Perkins coming in first, second and third.

I simply implied that plasma is the best 'term' for the "new state of matter" gel subtance that my patented device (sure, there are millions of patented devices) produces and supplies to the MEALER engine system as a power supply. It's not perpetual motion.... But with brainy people like you, I can't very well describe this in detail or you will potentially use it for some nefarious plan to get a Nobel Prize for yourself.

You shouldn't knock my plans, but instead come up with a better term than plasma or gel, even if they describe the fuel source fairly well.
