Actually yes they are – one of the most common arguments from climate skeptics is that CO2 cannot contribute to global warming because CO2 levels increase after the warming.
Wrong again. There's a difference between being the cause of the warming and contributing to the warming. Ya see genius, as the world warms the oceans lose the ability to keep gas in solution, and it gets released. Therefore it's more than possible that CO2 is not the DRIVER of warming but merely one feedback mechanism among many
no matter its source.
Of course they could get their predictions wrong, but climate scientists are the people best placed to make these predictions as they and assess the risk as they , well, study climate science for a living. The vast majority of them have predicted that it is likely there will be big problems for us as a result of our CO2 emissions.
Wrong again. The IPCC, which is in reality a handful of people not "thousands of scientists," even admit this in their own graphs. The graph of warming for CO2 is ridiculously low and that's based on what's likely an over estimated sensitivity. All the catastrophic warming scenarios are, once more, based on model predictions with the assumption of long term positive feedbacks, an assumption that's belied by the claims of climate stability to date, and a host of poorly understood feedback mechanisms. Specifically they don't understand the precipitation cycle, clouds, the reasons for warming at different atmospheric depths, the role of the oceans, nor have their models been able to properly backcast without massive manual adjustments, nor have their models predicted the current cooling trend because they admittedly leave out natural climate cycles like the pacific oscillation.
So who are “most sceptics” are they fully qualified climate scientists working in their field? What is the proportion of climate scientists who believe AGW is not likely to be a big problem and what is the proportion who dont ? I would like you to try and answer this question honestly .
I did, I said I don't know nor give a **** because it's completely irrelevant. If consensus is the result of a sound process it is still irrelevant. And it is the process that's in question here.
If you find “the vast majority “ of experts who actually do know what they are talking about agree AGW is a big problem that needs to be addressed why you think that you should ignore their advice for the advice of a very small handful of scientists who disagree ? Are you really saying that you are qualified to criticise the scientific method used in detailed climate research and of so what are your qualifications ?
If that vast majority of experts then leak a ****load of emails stating that their skeptics do have valid points but they should be ignored and denigrated and downplayed in public, and that they intend to stifle any public disagreement, freeze out any authors and editors who disagree with them, rig the review process, supress already published and reviewed papers, hide and destroy data in violation of federal law in the US and Europe, not to mention emails discussing specifically how to deal with skeptics regardless of credentials (according to Trenberth, just attack them as dumb and unqualified, sound familiar?), I'd think twice about their 'advice'.
My qualifications are that, unlike you, I can smell a line of **** when I come across it.
The Earths long term atmosphere has never been influenced by humans burning billions of tons of CO2 back into the atmopshere before .
Irrelevant to the point. The so called tipping point for the feedbacks is temperature, not CO2 levels. And according to several hundred peer reviewed and published studies, the Medieval Warm Period and other periods much further back in the Earth's history were not only a ****ton hotter than now, there have also been periods of massively higher CO2 atmospheric content, and
no run away greenhouse affect occurred. Hence why the MWP has to be removed from all IPCC and other alarmist graphs. And the reason CO2 levels aren't the claimed tipping point and temperature is, is because all these 'scientists' know damn well that CO2 is a bare **** percentage point of the atmostphere that's been massively higher in the past with no problems to show for it.
What they do say is for millions of years CO2 has been taken out of the atmosphere by plants. When these plants and huge forests died they eventually formed coal and oil. All this CO2 is now being being pumped back into the atmosphere (by burning the fossil fuels) in a very short time reverting CO2 levels to back before many of our ecosystems evolved which is obviously dangerous .
And they neglect studies which show in response to CO2 rising plant life explodes to suck in more. They deny it specifically because some of the trees they use to prove temperatures are so hot now are sensitive to CO2 fertilization. Wouldn't want that inconvenient truth getting out, because it not only means their research over states warming by failing to take into account for that group of proxies, it also means what most people with common sense already know: warmer temperatures are good for plant life. There's no shortage of life at the equator, plant or animal. It's in the arid regions of the Earth that life hangs on by its fingernails. The effects of global warming, even if true, are predicted to hit the higher altittudes, which means more arable land, longer growing seasons, more plant life. Oh the ****ing horror of it all.
No this is not the charge. The charge is that pumping out billions of CO2 into the atmosphere is causing the Earth to warm to a degree that could threaten the stability of our society.
Do you even think before you type? The stability of our society depends on that energy production for Christ's sake. The stability of
the climate may be at issue, the way to deal with it isn't to cripple our productive capacity by knocking out our major energy source.
No climate scientist has ever claimed that the Earths climate was marvellously stable until we started pumping CO2 into it. Quite the reverse actually.
Bull****. The entire argument of Mann et al is that the climate was stable for THOUSANDS OF YEARS and only just recently with our fossil fuel burning went up anomalously. That's the whole ****ing point of the hockey stick graph: a long period of little to no change followed by a huge increase in temperatures.
there is also some evidence that sunspots contribute to some of our present warming but that they cannot account for ALL the warming) we can reduce the effects by capping emissions.
Another bull**** claim. The reasoning behind the statement that natural causes can't account for all the warming is not study and data, but models. The scientists assume that because their precious models can't predict the warming without man made influences that there must then be man made influences. I don't think it's actually possible to tally all the logical fallacies in that line of reasoning without frying your own brain. And, those very same scientists admit in private their models are coming up seriously short. Not what they say to the public or put in reports of course, only to each other.
I cant really see how that is relevant but our climate when looked at in the long term is definitely not stable and is a constant state of flux.
Provincial in the extreme. Our climate is distinct to our planet alone and a single case study. Every other planetary body we know has temperature swings from deep freezes to boiling metal levels, sometimes within the same 'day'. That's not stability. Ours on the other hand is stable. Our Earth's temperature stays remarkably stable toward the low end of what's necessary to sustain life with occassional warming interludes.
1.Since the industrial revolution the planet has already warmed sufficiently for the icecaps to recede exposing more dark soil (ice is white and reflects heat darker colours absorb heat). Thus increased darker ground retains more heat , leading to more ice melting etc etc an unstable and unpleasant positive feedback cycle.
Antarctic ice formation is at an all time high, or was a year ago. Arctic ice is declining. The 'positive feedback cycle' is not only not proven, it's basically an assumption.
2.Melting ice due to aforementioned warming in point one causes arctic tundra to be exposed . Methane stored in the arctic tundra is now bubbling to the surface and being released into the atmosphere – methane retains heat much more than CO2. About 251 million years ago, at the end of the Permian period, a series of methane burps similar to this came close to wiping out all life on Earth.
Funny we're still here then... And actually we don't know the reason behind the PT extinction, it's hypothesized to be a mix of events, climate change being one of them. And it all happened
without SUVs. Now let us suppose this does happen again. Our response should be to... destroy our ability to create and produce any solutions of significance by artificially capping our energy usage. Because this raises the other inconvenient truth for climate alarmists: they want to duck and cover and not solve the problem. If anything, what you've just posted proves that with or without our help the Earth goes through changes which can make living on it a bitch. We can take your route, cripple our production, put on beanie copter hats hooked to generators and stare into the wind to generate energy, and kiss our asses goodbye the second a natural change of this sort occurs. Good plan. Can't wait to see how it comes out.
Or we can learn more about the climate and perhaps to a degree control it by introducing negative feedbacks of our own. We can't do the latter however if everyone but Al Gore is reduced to subsistence levels of living while he and his ilk get richer and fatter taking the results of our hard work and using it to buy and sell carbon offsets from each other. Stone age societies don't deal with complex problems very well. We can't even do what you want and 'develop' the alternatives without using oil. How the **** are we supposed to do it? With what capacity, what income, what resources? It always takes
greater than one unit of low grade energy to produce one equivalent unit of high grade, economically desirable and usable energy. So that means no matter what fossil fuels will be a part of our lives for a long, long, long time. It is upon the productive capacity we get as a result of using them that we can build nuclear, geothermal, solar, wind, tidal, etc. What you are proposing is to wipe out and/or severely limit the use of the higher order energy commodities that are necessary to develop the ones further down the structure of production for mass use as the less desirable ones move further and further up the structure of production. Once more, great plan. Can't wait to see how it works out for everyone.
3.As the atmosphere heats the oceans heat. The oceans can hold less CO2 the warmer they get. The more CO2 and other greenhouse gases released form the oceans the warmer it get setc etc another positive feedback situation.
Tom Segalstad said:
CO2 in the atmosphere and in the ocean reach a stable balance when the oceans contain 50 times as much CO2 as the atmosphere. The IPCC postulates an atmospheric doubling of CO2, meaning that the oceans would need to receive 50 times more CO2 to obtain chemical equilibrium. This total of 51 times the present amount of carbon in atmospheric CO2 exceeds the known reserves of fossil carbon- it represents more carbon than exists in all the coal, gas, and oil that we can exploit anywhere in the world.
Also, the ocean like the land is likely to increase biologic activity with warming which increases its storage capacity, which puts this 'tipping point' even further out of reach. Also, there have been times in the Earth's history with massive CO2 concentrations and incredibly cold conditions. If CO2 is the overwhelming driver of climate change claimed, this should not be possible.
Whether the original warming is human generated or not is irrelevant – the point is we should do as much as we can not to excaberate the situation by using dirty fuel sources that pump greenhouse gases into the air. If you want an example of a long term positive feedback system in which CO2 levels spiralled out of control and then created a stable , burning hot atmosphere – look at venus.
Actually that's not what happened to Venus, but that's besides the point.
Although sunspots may be contributing to our present warming the fact the fact that temperatures have risen on an almost identical trajectory with CO2 emissions since the industrial revolution is a fact Id also like you to explain .
They haven't risen in direct trajectory with CO2 emissions. That's one of the problems with the data. One of the other problems is that even after the hockey team massages the data so it appears there is such a correlation, correlation is not causation. Your team of qualified 'scientists' also has the tendency to cut temperature graphs off right at the end of the Medieval Warm Period or the Little Ice Age depending on the scale they're dealing with, giving an expected natural temperature recovery the look of being an unprecedented increase, which is their way of heading off the question of what caused all that similar and even hotter warming in the past when there were no CO2 emissions of note other than natural sources.
Who are GISS ? Until you actually come up with some reasonable arguments and facts for me to change my mind why should I ignore the opinion of the vast majority of climate scientists and instead adopt yours ?
You're trying to debate this issue and you don't even ****ing know the Space Institute, much less their role in it? Areyou typing from under a ****ing rock right now? GISS = Goddard Institute for Space Studies at Nasa, Gavin ****'s and Jim Hansen's home, the runners of the Real Climate site. Gee, you'd think someone as knowledgable as you on this subject would know who produced what's supposed to be the second most reliable temperature reconstruction for the planet...
I just think its ridiculous that so many people who are not climate scientists feel they are qualified to dispute what the the vast majority of climate scientists.
I know a patent clerk who disputed newtonian physics. What a presumptuous prick he must have been.
You can huff and puff as much as you like but at the end of the day I will trust what the majority of experts say over you or a handful of scientists say any day of the week. If the vast majority of scientists suddenly said – look we got it wrong everything will be OK AGW is nothing to worry about then I would listen to them .
Majority has no meaning in science, it is irrelevant. That you keep falling back on it shows you don't actually have a clue what you're talking about nor have you given a single critical thought to any of the arguments for or against global warming. You're still in parrot routine. The rest of your post is thus, not worth my ****ing time.
