Title: Do you support catastrophic climate change
Post by: justaskin on 20/02/2009 09:56:12
As requested.Do you support the idea that the climate is changing in a catastrophic way or is just the result of normal climate change.
 
I don't and have been asked for some proof from the Australian Bureau of Meteorology.
I have only used the site of Sydney Airport if people want to trawl through the many other sites in Australia to prove me wrong then go for it.
First rainfall for the years 1971 to 2000

Sorry I can not get the links for temp and rainfall to work.So I am afraid you will have to take my summary for both for the time being

You will note that the annual average rainfall over this period was larger than the long term average.
Next the temperature for the same years
This does show a slight increase on annual average of 0.1 not exactly the 1 degree quoted in other parts of the site.
And finally severe weather which we get mainly in the form of tropical cyclones.

http://www.bom.gov.au/weather/cyclone/faq/index.shtml

You will need to go down to the section climatology  and click on question 6 of that section.
In essence it says that if anything there has been a slight decrease in the number of severe cyclones.
All in all not much to suggest we are in the middle of a catastrophe.

I was also ask for some proof that the  Australian CSIRO our premier scientific organization was not the trusted body it once was.

http://blogs.news.com.au/heraldsun/andrewbolt/index.php/heraldsun/comments/csiro_heavy_says_dont_trust_csiros_scares/

This article quotes Art Raiche who worked for CSIRO for 35 years, the last 15 of which he held the rank of Chief Research Scientist.

Now for the IPCC.

Your chances of finding a scientist in the IPCC who disagrees with climate change  are less than finding a Muslim  in a mosque who disagrees with Islam.

And why don't the IPCC release the data and the models they use in their decisions what are they trying to hide.

And why of the 190 odd countries that are signatories to the Kyoto protocol is it only the 39 developed nations that have to do anything about it.
One would think that if you are all in a boat with a hole in it it is counter productive to be arguing who made the hole better for everyone to start bailing.But in the case of the developing countries not only are they not helping they seem to be intent to bail water into the boat.

As I have said in other threads here climate change is about two things
MONEY and POWER

justaskin - have a look at this link:

http://www.bom.gov.au/cgi-bin/silo/reg/cli_chg/trendmaps.cgi?variable=rain&region=aus&season=0112&period=1970

It will provide access to trend data for a variety of periods and for a variety of climate variables. It may be useful in your original post.

There can be no doubt that facts and figures can be found to prove or disprove global warming/climate change. In some cases even the same facts & figures can be used to serve either purpose.

It's a bit like you saying 'the glass is half empty' while I say 'the glass is half full'.

Look at it this way though; if GW/CC is not happening, or if it is, but not as a result of man's actions, would it be damaging for man to reduce the extent of man made pollution?

If GW/CC is happening as a result of man's pollution and we do nothing about it, what would the consequences be?

Is it not better to er on the side of prudence and reduce our use of fossil fuels, reduce our waste etc.? Could environmental friendly actions actually be counterproductive?

The problem is, if we get it wrong, we may not have the chance to put things to right.

Biodiversity is essential to the world's ability to support life. Can we afford the relentless spread of man to wipe out rain forests, threaten microscopic sea life and cause countless species to become extinct?

And just a comment about the typhoons. They are driven by rising warm moist air. Since the patterns of where this moist air will be are changing, it would follow that where and the number of typhoons that form will change. So, it would not surprise me if there was a predicted reduction in expected typhoons in and around any given area. It is because of the changing climate that this is occuring.

Thanks denstudent that site will do for now but as a trend it does not account for individual places.But even from the trends we are only looking at 50mm of rain and 0.1 to 0.2 deg of temp.
The thing with severe storms is they keep telling us they are increasing and from the statistics they are not.

I think that the thing to do is to identify ONE thing to discuss to its (logical) conclusion, and try not to bring in things that are irrelevent to the discussion. We (whoever wants to be involved in the discussion) should all agree on one topic, for example, changing precipitation patterns or temperature gradients etc. Since it is your thread justaskin, perhaps you would like to propose the first topic as a hypothesis?

I think there maybe a little misunderstanding here. It is not the quantity of sever storms that are predicted to increase but their strength and severity, infact their quantity is predicted to fall...fewer, but more severe.

What you are talking about here is insurance.So how much insurance should you have.You don't pay more in insurance then the cost of the item you are insuring.
You say we should err on the side of caution.Should we also take precautions against the world getting colder or just against it getting warmer.

Exactly. If we go for warming and it doesn't happen then what.I think it is better to risk warming then to risk cold.

On this we agree but don't expect a down turn in world population anytime soon.In fact it is almost heiricy.

Maybe it is just my paranoia kicking in but there seems to be some kind of concerted effort to close this discussion down.I was first asked to to post in a separate thread,which I did.And now I am being asked to break the topic down into how ever many small parts.
The topic is climate change.If that is not appropriate then remove the thread.

justakin, as I wrote in my post:
Quote
Could environmental friendly actions actually be counterproductive?


I don't think any of us are qualified to decide which is the best course of action (or in-action) to take.

Australia is suffering from extreme heat right now, while the UK is enduring a harsh winter.

Is that Global warming, or climate change?

The Gulf & Jet streams have altered direction. To what? A direction they have never taken before, or the direction they used to take a few 1000 years ago?

You say
Quote
don't expect a down turn in world population anytime soon
. Do you mean a downturn in the numbers of humans, or in the number of species? If humans, I certainly don't expect to see any reduction, quite the opposite. If the number of species, you may well be right. As some become extinct, so others evolve, but we can do more to ensure that we do not cause the extinction of species, which at the moment we do.

I agree with you that it is necessary to debate the whole issue, since different aspects are linked, but dentstudant is also right, in that trying to debate the whole issue gets very complicated.

What to do for the best, I do not know.

No, there is no attempt to close it down. There is, however, an attempt to rationalise the discussion into sub-topics. In my experience, nothing is ever gained by trying to discuss a topic as large as climate change as one statement. It is therefore better to discuss individual elements within the broad subject. At the moment, I'm not trying to prove or disprove anything. All I'm saying is, let's agree one topic that we can have a discussion/debate about in an effort to improve everyone's understanding. We may reach a concensus on this topic, which means that we could then discuss another one. It also means that we will be able to construct a knowledge-base.

Justaskin, if you don't think that this is possible, then it is my opinion that it is impossible to have any sort of valuable discussion.

No that is not correct two states South Australia and Victoria went through heatwave conditions a week or so back but that is not an unusual occurrence at this time of year.Most of the rest is under water.

No to me that is just Australia.

I must have misunderstood your first reply but yes I was talking about humans.You say at the end of your quote that we are responsible for species extinction so how is more of us going to reverse that.
We have to reduce the number of humans on earth if we don't then us or the earth will do it for us.

Temperature
Rain
Storms
IPCC
UNFCCC
Carbon trading
Etc?.

If that it the way that you want to do it, then that's fine. I would propose to start with something tangible, such as one of the climate parameters since those are the drivers of the whole process.

Post by: Karsten on 21/02/2009 15:56:33
I am all in favor of scientists questioning the statements of other scientists. Especially when evidence is brought forward that may contradict current scientific truth.

I wonder though, and I have asked this question in several other places, whether there are still large, independent, professional science organizations that question the existence of global climate change and human activities as at least one of the major causes. It seems that those organizations would not support a theory if it was not sound.

Can we (relatively safely) assume that global climate change is happening and is influenced by human activities when the American Association for the Advancement of Science (AAAS,~150,000 members) says so too? How can you find better and more reliable scientific statements? Is what they officially declare just an opinion that can be swept to the side by any individual?

Whether this change is or will be "catastrophic" is difficult to say. It may be for some, it may not be for others. It may not be where you are but it may result in death and mayhem somewhere else.

I believe no one knows what is going on if anything.. The climate is governed by too many unknowns, and their is no real evidence that we are doing anything detrimental. The science is way to complicated and totally beyond us all.

I don't understand such comments. It may be difficult to understand what is going on. Scientifically speaking that is. Many things are. Most don't bother us because they do not require us to change anything. However, there are thousands of scientists quite busy with this topic and they have come to certain conclusions. From what I understand those conclusions are that the global climate is changing faster than it should and that human activities are to a large extend causing this change. So, yes, we are doing something detrimental. We just cannot see the results immediately. If you turn on your car while it is with you in your closed garage it will take a few minutes for you to experiences the detrimental effects of your action. What we do as a species is in principle the same - you just have to wait longer for the effects and it is more complicated than that.

Why do we trust teachers, dentists, electricians, engineers, priests, car mechanics, day-care providers, city officials, etc. but we do not trust the carefully phrased, peer-reviewed findings of the best scientists on this planet in regard to climate change? Is this still a science issue?

Of course those findings could be wrong. I am certain that they will be adjusted like any scientific knowledge occasionally needs adjustments. But you have to ask yourself four questions:

1)What if they are right and we do nothing?
2)What if they are wrong and we do nothing?
3)What if they are right and we change our ways?
4)What if they are wrong and we change our ways?

Those four scenarios have meaning. One (the last) may be wicked expensive and we will look back and think that we panicked for no good reason and will never listen to science again that quickly. Another scenario (the first) may end life for human beings on this planet. It is a matter of intelligent risk management. The first scenario is just not acceptable. We cannot do nothing.

A good number of the people on that list are not trusted.

Quote

The reason that I don't trust the scientists on the IPCC panel is because some of them have been caught massaging data to support their position and the fact that the IPCC does not have any scientists on the panel that actually disagree with the hypothesis of climate change.If the IPCC was a truly representative body of scientific opinion there would be one or two scientists that don't support the hypothesis on the panel.
The other thing about the IPCC is why don't they freely publish their data and modeling
so other scientists who don't support their position can peer review their data and methods.What is the IPCC hiding.
I would be more prepared to support climate change if.
1)The science was more open.
2)If I didn't see banks and financial institutions lining up to run carbon trading schemes
3)If I was not being bombarded on a daily basis by climate alarmists with outlandish statements.
4)And finally if I could see some tangible evidence of a change in the climate.

First, to be rigorous about this, justaskin, you need to do your homework.

The climate is NOT restricted to Sydney Airport and the data for that site OR is it restricted to just Australia - it concerns the whole world, the weather and ocean currents, as ocean currents are driven by the wind and the two forces interact. No meaningful approach can be made until that fact is taken into consideration.
After you have looked at and managed to wade through all of the data for the world, then I would consider you opinion informed.

I will also state that MY opinion is not informed with respect to what I just suggested that you do. I am somewhat more informed as I have studied the effects of climate on my field of science, sedimentology, a branch of geology that concerns both sand deposits and limestone deposits, including coral.

I am sure that being Australian you are aware that the Great Barrier Reef is in a drastic decline. Many scientist, MOST scientist, in fact Australian Scientist, believe it is due to to climate warming that has also raised the water temperatures of the ocean the reef is located in.

http://www.gbrmpa.gov.au/corp_site/info_services/media/media_archive/2009/2008_01_07

SO in at least one respect, your statement that Australia is not experiencing climate warming is incorrect. It has been measured by the Australian Government. Park scientists, not the CSIRO.

Now for Art Raiche. He is one person. Is it scientifically correct to base a conclusion on the opinion of one person rather than a larger number, both of these choices being from people who are informed about climate and its effects? NO. it is downright counter to the scientific norm.

You said 30,000 scientists are dissatisfied with climate models - yes, that is true. It is damned difficult to get all of the variables into the model to do one that satisfies everyone. I believe there are more than half a million scientist in the world that are satisfied that the models are the best now available.

Fourth, you asked "And why don't the IPCC release the data and the models they use in their decisions?"

You obviously didn't check their web site (or your grammar - FOG). Start here - http://www.ipcc-wg3.de/activity . It will lead you to the meeting reports, the scientist involved and the publications that are available in scientific journals. You will also find original reports, with science and everything included at this site, including http://www.ipcc-wg3.de/activity/publications/ar4/working-group-iii-fourth-assessment-report There is one hell of a lot more data and research there, as well.

Next, you asked "And why of the 190 odd countries that are signatories to the Kyoto protocol is it only the 39 developed nations that have to do anything about it." The reason is simple. These 39 countries account for 99% or more of all the problem that are to be addressed by the Protocol.

Now, as I am not a person who does climate study full time, but am only do it as a PART of the rest of the science I do, I do know a few things about climate change.

1. The climate is always in flux
2. For the last 13,000+ years the world's climate has been slowly warming - 15,000 years ago the Sahara Desert was a grassland, the Gobi Desert was very much smaller and glaciers covered most of Canada, parts of the northern US, Europe, Scandinavia, The Himalayas, much of Northern Asia were all under hundreds of feet of ice.
3. The Southern Hemisphere is less affected by climate variation than the northern hemisphere. You thus would notice it less in Australia than in Europe or America.

It is my conclusion from these facts - not opinions, but things that can be checked from independent sources - that the earth has been warming for at least the last 13,000+ years.

Now for the main question - all of the evidence points to the fact that man is probably responsible for the escalated increase in the mean temperature of the earth in the last 200 years. I said "probably," not conclusively - but that probability is much greater than 50-50, it is more like 85%. It began rising much more when coal became more important as the Industrial Revolution took place. http://www.cru.uea.ac.uk/cru/data/temperature/ & http://www.seed.slb.com/en/scictr/watch/climate_change/change.htm

That is an educate, informed OPINION. Notice three words "educated and informed" and OPINION." I see none of the first two reflected in your posting. According to you it is all due to money and power. I guess conspiracy theorist will not ever try informing themselves first before they express an opinion. This is contempt prior to investigation. 

That is part of the conspiracy-theory oriented, paranoid mind.

Then why wasn't it a problem 10,000 years ago or 1000 years ago or 100 years ago or even
40 years ago.Then we were all told by the scientists we were entering an ice age.
Have a look at any temperature graph for the last 200 years and tell me why if global temperature rise  is in lock step with CO2 increase did the temperature fall from 1880 to 1910.That would be when the industrial revolution was in full swing.So the temperature should have been going through the roof but it didn't.Why?.
Quote
Now for the main question - all of the evidence points to the fact that man is probably responsible for the escalated increase in the mean temperature of the earth.
No all the evidence does not point to man.There is evidence of water vapor's effect there is also evidence of sun's effect

and am not entitled to an opinion.
Correct me if I am wrong but when did I say I had done any scientific work.
If being a scientist is a criterion for be allowed to  comment on climate change then I guess that lets.

Then there was no point in you posting the question - you didn't want to discuss it - you wanted to argue your opinion, not the science of the subject in question. So as far as I am personally concerned just go away. You are contributing nothing and taking up bandwidth that could be better used for scientific discussion, not conspiracy theory-mongering. This site is for people interested in science, not the purveyors of conspiracy theory. If we wanted that, we would read newspapers owned by Rupert Murdoch.

This site cost money for ever bit of traffic used. You are wasting the money.

[pokes head in to discussion]

You will not get banned for voicing an opinion on climate change, this site is open to opinion and discussion. What you do need to do is stop the hijacking of threads just to post that climate change is not happening when that is not the question.

You will find though, that people dismiss what you have to say. This is not because they are trying to silence debate but because you have a closed mind and are not willing to engage in proper debate, you also have a very angry attitude in your replies to people.

There is nothing wrong with openminded debate from people who are willing to listen to both side but you are closed, unwilling to listen or even think that you could be wrong. I listen to and discuss with meteorologists, climate scientists and just about anyone with an opinion, you must be willing to do the same, you must be willing to review your own sources of information.

The people who post in this section of the forum are meteorologists, geologists, students and people with a genuine interest in these sciences. But, unless you are a climatologist you are relyinying on the data of others. It is up to you to then interprit that data or rely on someone else doing it for you. Again, you need to check your sources and see not only if they are correct, but if they have a vested interest in holding that view or opinion.

You may also wish to read up on Stu Ostro (http://www.weather.com/tv/personalities/Stu-Ostro.html?from=tv_pers_welc) He is the Senior Director of Weather Communications at the weather channel, he was once a adamant skeptic but is now in the global warming / climate change camp.

Note:
One of your main assertions is that the climate is not warming, this is a strange view to hold, even climatologists and metorologists who don't agree with man made climate change all agree that the climate is warming they just think it is part of the natural cycle.

Title: Do you support catastrophic climate change

Thank you Paul for your comments I will take them onboard.
If I said that there was no rise in global temperatures over the last 100+ years then I am obviously wrong as any chart of such will show.
I would not say that I have a closed mind as far as the science is concerned just that I currently think the observations don't support CO2 as being the main cause of temperature rise.
So one question if I may(actually two)that I have never been able to get an answer too.
If you take a chart of both temperature and CO2 concentration in the atmosphere over the last 200 years.
Why was there a drop in temperature during the period 1880-1910 and a plateau of temperature from 1940-1970.Surely if you were ask to carry out a scientific experiment to show the link between CO2 concentration and temperature you could not say there is a direct link.The only thing you could say is that they both rose over the period.
If there is a direct link between CO2 concentration and temperature how is it that CO2 concentration has risen by roughly 1/3 over the last 100 years but global temperature has only risen about 10% of the amount.
Regardless of what you might think of me I would appreciate your explanation.
It may seem strange to you but I started out on the pro side of the debate.I have used solar to heat water for the last 30 years and will in the near future have a 1KW grid connect solar electricity generator.But due to apathy from government's and the hypocricy of some people in the environment movement I have move to the skeptic camp for the time being.

Thank you for being more open to discussion and saying that there is another side to the debate. 

The answer to the two questions is rather simple. Direct correlation is not possible. There are too many other factors involved as well. It is why no one is satisfied with climate models - there are just too many variables to consider. BUT many of these models do a fair job at replicating the past so they must not be discounted out of hand as they are very useful tools for climatologist.

Also, temperature will not respond directly to just one factor, such as CO2 as suggested above. Climate is much more intricate than suggested by your post. It responds to a large number of factors.

There is a highly probable relationship between CO2 and climate warming. There are many other factors as well, including the fact the climate has been warming for 13,000+ years. These factors include, but are not limited to, methane emissions - worse than CO2 (see 1., below,) nitrogen oxide and nitrogen dioxide, sulfur dioxide and one of the most important green-house gases, water vapor, as well as other gases that also must be factored into the equations. Fluorocarbons have effected the southern hemisphere more than the northern and the increase UV increases species loss and thus ecosystem loss.  There is also solar activity to be taken into account. The state of the earth's magnetic field, which seems to be deteriorating in intensity, may also be a cause for warming. There is just too little data to on magnetic variations to say definitively. Volcanic activity and war, especially WW II, caused and still causes large amounts of debris to be injected into the upper atmosphere where it lingers for long periods of time. This counters the warming effects of other factors and MAY be responsible for the 1940 to 70 reversal.

What is important is that by several means, not just carbon emissions, man is most PROBABLY accelerating the warming that is going to happen and has been happening. Other major factors in man's effect on climate are global deforestation, cattle and sheep ranching, oceanic pollution that destroys ecosystems that use CO2 and produce O2, fluorocarbons, deforestation due to acid rain, deforestation and other enviornmental imbalances caused by the transfer of insects and animals from one ecosystem to another, (e.g. rabbits, rats and mice in Australia), etc. 

Should we do something about this? If you are a fatalist you can say "In 1,000 years it won't make any difference." If you care about how you and your family are going to live in the next 15 years, YES - you should care and err on the side of caution by cutting emissions drastically and encouraging others to do so. It seems that you are already taking steps to do this. Wonderful!!

The data cannot have a direct correlations due to the number of variables. Yet the data does suggest that there is a very large certainty that CO2 is one of the two major causes of accelerated global warming.

Cattle population has risen in the last 200 years from less than 200,000,000 head to nearly a billion head of cattle - Wikipedia   Also, methane is produce by all ruminates, including sheep. There are well over a billion head of sheep at present. These two populations produce a lot of methane - and what do you think nearly 7 billion people do to the amount of methane when feces is processed in sewer plants or broken down by the environment?

Thank you JimBob for your explanations.
It is as you say the complexity of the subject that is one but not the main reason I come down on the skeptic side.
The main thing that tips my hand is that by and large people don't want to do anything about it.
I wonder what the carbon foot print of international sport is each year.
What if the IPCC and the UNFCCC said we must ban all international sporting events because of their huge carbon footprint.The idea is laughable, but why. If CO2 emissions not to mention
the effects on the atmosphere of aircraft are so critical don't we do everything we can to stop it.We don't need elite sport to live in fact we would probably be much fitter if there
were no elite sport.
Do you not think it is a little strange that we are considering herd reductions in a world were hunger is a real problem yet we do not consider reductions in areas that would make no difference to our daily lives

The main thing that tips my hand is that by and large people don't want to do anything about it.

But most people live by what they can see, smell and touch. They don't see the climate change, and when you have severe weather they see this as proof that there is no global warming / climate change. They also figure that they personally will not be living when / if things go bad...so why care!

The situation is then made worse by politicians, who on the whole, only make policies for the length of their term in office. They need to show that the money spent has visual effects so they can get reelected.

Personally, I think the only way to get people to change is by giving them an incentive. In the UK (and elsewhere I guess) people moan that they have to separate recyclable materials and put them in a different collection bin. No real hardship, but a lot harder than dumping it all in the one bin.
We need a system where the householder is paid, say by weight, for their recycled material. Heavily subsidise water storage tanks, solar panels and the like, encourage people to use them to save them money, not to save the environment.

I do think people are sick of being told they need to do this and that, watch their carbon footprints and act now to save the future. They just want to save money and have cheaper bills. In the present climate of recession this should be an easier thing to do. If the motorcar industry has to be bailed out then attach conditions that they must improve fuel performance, improve battery technology as well.

But why not also subsidise the green markey of personal wind turbines, solar panels, water storage tanks...this could also create jobs...

Where I live, Austin, Texas, there are the considerable incentives for the use of energy saving and producing devices. There are city subsidies for weatherizing homes, decreasing water use and driving less (new metro rail system in planning stages). Also, home power, solar panels, etc., are encouraged and ad velorum tax credit given for home owners who install these.

Why? The electrical utility is city owned, as is the water treatment facility. And this metropolitan area is one of the fastest growing in the US.  When I moved here in 1950, the poulation was less than 100,000 including 40,000 students at the University of Texas. By 2015 the projection is for 1,500,000 people with many more on the way. There are at present right at 1,000,000 in the five county area comprising the greater Austin area. All infrastructure is stressed.

Addressing another point. I quote from above "Do you not think it is a little strange that we are considering herd reductions in a world were hunger is a real problem yet we do not consider reductions in areas that would make no difference to our daily lives"

Meat is the most inefficient way for the human body to get protein. The use of land, the amount of energy needed to produce it, the water needed, all make meat an impractical way of satisfying the nutrition needs of a large population. Any any ecosystem the less efficient a population of organisms, the less their chance for survival - that is a general, basic principal of population dynamics.

Yep JB, I agree, meat, though very nice, cost a lot more resources by Kg produced than soy beans. I personally hate the discussion of animal made methane, it sounds so ridiculous when discussed, but I think you are correct when pointing out that we by raising live stock do add to the methane. But the problem for the moment I believe to be CO2, if we can lock and reduce our manmade CO2 production we might be able to control the releases of methane from the tundras and under our oceans.

The problem with controlling CO2 is that its 'life cycle' in the air seems to be from fifty years up to (?) And this is a big problem, as I understand that to mean that if we stopped producing any man made CO2 today the concentration in the atmosphere from our day before wouldn't be reduced into a heatsink like trees or our ocean for at least fifty ears.

So if I understand this right it means that what's getting 'taken up' in our heatsinks today is made around fifty years earlier. The concentration in the air will drop off if we stop contributing new man made CO2, but it also means that if we succeeded with that, rather far fetched, goal there still would be more CO2 than our planet in itself produces for at least fifty more years.

The methane in the tundra is already getting released, there are this 'crazy' :) Soviet researcher Sergei Zimov who built an observation post on the tundra to document it. http://archives.chicagotribune.com/2008/may/05/news/chi-siberia-loner_rodriguezmay05
And the story is collaborated by independent sources. http://www.sciencepoles.org/index.php?/news/new_study_shows_arctic_permafrost_releases_methane_into_atmosphere/&uid=1401

And there is releases from under the shallow waters up at the North pole too where the methane hydrates aren't that deep down as in tropic waters where those 'gas hydrates' may be at depths from 2000 meters to 10 000 meters.

"Gas hydrates are a potential energy source found in permafrost environments and under the sea floor. They form when water and methane gas come together under extreme pressure and in a cold environment.

The water and gas are frozen together at a molecular level. One cubic metre of gas hydrates contains 164-cubic-metres of methane gas, and 0.8 cubic metres of water."

In Siberia Oerjan Gustafsson of Stockholm University in Sweden told the Independent newspaper in an email from the vessel Jacob Smirnitskyi.

"
"An extensive area of intense methane release was found. At earlier sites we had found elevated levels of dissolved methane. "Yesterday, for the first time, we documented a field where the release was so intense that the methane did not have time to dissolve into the seawater but was rising as methane bubbles to the sea surface. These 'methane chimneys' were documented on echo sounder and with seismic [instrument]."

At some locations he said concentrations of the gas were 100 times the background level. These anomalies were documented in the East Siberian Sea and the Laptev Sea, covering several tens of thousands of square kilometres. Gustafsson added: "The conventional thought has been that the permafrost 'lid' on the sub-sea sediments on the Siberian shelf should cap and hold the massive reservoirs of shallow methane deposits in place.

"The growing evidence for release of methane in this inaccessible region may suggest that the permafrost lid is starting to get perforated and thus leaking methane."

Estimates for the amount of carbon locked up in the hydrates vary from 500 to 5000 gigatonnes. Scientists predict that warming will release some of these deposits, but modeling the temperature rise that would trigger significant releases has proved extremely difficult."

But we need to stop the CO2 first, that is our top priority as I believe it. The 'real' methane releases won't come until CO2 have warmed our oceans. Did you know that the waves on our oceans are already moving faster due to more 'heat' stored in them? http://www.newscientist.com/article/mg19426075.400 and http://www.esa.int/esaCP/SEMRLH12Z0F_index_0.html

The 'root' to the problem is still our CO2.

Well yor-on I sincerely  hope that is not the case because if it is then I think we are screwed.Because the developing world by and large has made it plain they will not be reining in their emissions until they have reached a standard of living commensurate with the developed world.It would seem that the chances of there being a leveling out of emissions let alone a reduction, any time soon, are extremely remote.

You know Justaskin :)
Just when we think that things can't get any worse...
They do:)

On the other hand, we've fixed it so far.
So I fully expect us to come through again.

But even if I'm wrong, we still have a lot of good environmental reasons why we should change our energy sources. And btw, I won't mind being wrong on this one a thing..

Ah, global warming that is.
