back to article Boffin dubs global warming 'irreversible'

Economies may rise and fall every few decades or so, but at least the hard work we've put into global warming is "irreversible" on the human time scale. That's according to research from a team of US environmental scientists published today in the journal Proceedings of the National Academy of Sciences. The report claims that …

Too bad they don’t offer the same on their seasonal forecasts. the last two winters were forecast to be warm in Alaska and the lower 48 states.

    Just what makes anyone think that a minor skin infection like the human race is going to have any significant effect on the earths' climate?

    The climate has been changing for eons; it is continuing to change (we're still exiting an ice age); and it will change no matter what we do short of detonating every nuclear device on the planet and clouding up the atmosphere. That would cause a minor blip.

    Predicting long-term (i.e, thousands of years)climate trends based upon a few hundred years of observations is nonsense.

    This thinking is only if we stop producing CO2 and then sit on our arses twiddling our thumbs. Of course climate change is irreversible if we don't bother doing anything about it. On the other hand if we actively remove the CO2 from the atmosphere then it is reversible. The technology already exists to remove CO2, it is just a matter of perfecting that technology and making practical.

    Also there won't be any london coral reefs if the oceans CO2 level continues to rise as coral reefs simply wonty be able to exist in oceans that are much more acidic.

    Climate Change is as inevitable as night following day...

    and that's an undisputable fact. The important aspects for humans is how badly will it affect us and what do we need to do if the badness is unacceptable. First define "badly", "affect" and "acceptable", then define "need" and then look at the "doing" bit. Clearly, There is a lot of "politics" here. The average "Western" family may find the cultural adjustment of going without their grilled steak dinner just too much to tolerate at the moment. It is prudent to take a few precautions - like we didn't with the current banking crisis and "toxic debt" - so I'll not go along with a scare mongering line too far. The essence of the messages in the article and the comments is that we need more hard science not reports of reports. If that means some less "rationale" stuff gets published it is a price a skeptical public will have to pay.

    Atlantic Conveyor

    I think the Gulf stream is meterological. It's the sea current conveyor that keeps us moderately warm, taking the cold arctic melt-waters deep down and south, whilst bringing warmer waters from the southern ocean along near the surface. Too much melt-water from the arctic will stop the cycle and we will begin to enjoy some serious winter sports on the south downs !

    Should the conveyor weaken or stop all together the effects will be dramatic and fast (gulp).

    IIRC, and someone correct me if I'm wrong, humans produce about 3% of the world's annual CO2 output. So even if we stopped, it would mean that there was 97% of its annual production left untouched.

    Yes, our 3% can make a delicate equilibrium unstable or shift it a bit, but we'll never be able to make rapid change as expected by our hemp-wearing friends.

    What we need now is someone to determine what effect we've actually had given the whole cyclical nature of... well... Nature. Take a look at a long-term graph. A million years or so. You'll see the cycles emerge neatly. We really are pretty insignificant.

    All scientists fiddle the results to form the conclusions they wish to prove. While i can agree that the ongoing polution is clearly not going to be good for the environment, there has not been enough collected data on the weather cycles of this planet to draw any definate conclusions.

    This could be nothing more than a natural cycle.

    @Ogden Freen (is that your real name?)

    There isn't a scientific consensus in support of AGW. The IPCC is a political group (with a tiny minority of the world's scientists as signatories to its propaganda, sorry, reports).

    Plus, since when did consensus automatically equate to truth? There used to be a consensus that the world was flat (based on all the available evidence at the time.....)

    PS. In case you hadn't noticed, the majority of fossil fuel moguls are now tacitly in favour of the AGW scare (because there's money to be made from carbon exchange and they pull the strings).

  30. Ian Tunnacliffe

    Probably true

    James Lovelock is interviewed in the current New Scientist. He simply takes it as read that catastrophic climate change is coming and there is now almost nothing that can be done about it.

    That may still be an extreme position but it's not that far from the scientific consensus as exemplified by the IGPCC - which has historically been extremely conservative in its assessments.

    Now, I'm a physics graduate so I can understand the basic science (not that the degree is necessary - any intelligent human prepared to put in a bit of effort could do so). If I were able to put a bet on it would be with the scientific consensus and against the deniers, almost regardless of the odds William Hill might quote.

    There is an opportunity to ameliorate some of the worst effects if we take it seriously, but we should still be planning for a world in which Bangladesh is under water full-time instead of just when a cyclone strikes.

    Climate scientists must report that the Earth is warming, otehriwse their fat grants will stop rolling in. They are NOT impartial. Most of their data is heavily massaged (NASA) or based on a single (or, at least, very small number) of reports (IPCC). None of their computer models are in anyway accurate - just look at how often they talk about getting a "feel" for the numbers. Sounds suspiciously like faith in an an unverifiable truth if you ask me.

    Anthropogenic Global Warming/Change is a total myth; a scam, a lie. This does not preclude "green" initiative for a number of other reasons (oil will run out, killing rivers is bad) but this has NOTHING to do with the AGW/C fairytale.

    The Earth is coming of the end of an ice age so OF COURSE IT IS WARMING UP, YOU MORONS! That's kind of what coming to the end of an ice age MEANS! Climate Changing? Well, duh, END OF AN ICE AGE!!

    Is this the "scientific consensus" that gave us last week's scare about temperatures in Antarctica? The Beeb faithfully reported it as fact. Then we found out that there aren't many weather stations in the area, so the weather twonks used satellite data and "a computer model" (algorithm not released) to determine what a weather station in Antarctica might have recorded, had it been there for the past 50 years.

    All very fine, but then it's presented as incontrovertible evidence, not with the caveats that it's all just a computer model that might be inaccurate.

    Oh, and one of the modellers was Michael Mann, of "Hockey stick" fame. Not a man with a history of faking statistics. Oh no.

    @Eric Werme - those "harsh words" from don't seem to add up to much of an argument against the paper. (1) there is a great difference between modelling climate and forecasting weather for a couple of seasons, climatology is about the trends and long-term mechanisms, (2) the ozone story they link to is about another scientist's findings and doesn't invalidate anything about Solomon's previous work, (3) they don't give any substance to the AR4 criticism, so it relies on us already sharing their opinion that the IPCC report is flawed.

    No irreversible

    I was a bit confused by this because the argument appears to be that it's irreversible because it would take at least a thousand years to reverse it.

    Now I'm not a contrarian, in fact I generally agree with science, but it seems to me that "a bit slow to reverse" and "irreversible" are not the same thing at all.

    Also, who knows, maybe all those climatologists that the contrarians and oil-lobby shills hate so much for being experts on the climate will start coming up with solutions that allow us to turn things around faster. With a bit of luck we could get things sorted out within 700 years or less!

    Don't know about Global Warming, but neither does she.

    According to my old globe, the oceans represent even more of the total earth surface than the selectively ignored Russian northland. We have a few random records of ocean temperatures prior to World War II. There might be useful recent sea surface information, but It appears that the people in charge of satellite data have been manipulating the records to increase their budgets, and the politicians have eagerly leaped at the opportunity to extort a new tax.

    Mankind has significantly affected weather patterns. Humidity goes up when you create major reservoirs. Ditto for the huge cooling towers for the nuclear power stations. The stagnant brown cloud over our extensively paved and air-conditioned cities, wouldn't have formed without some help from mankind.

    But remember man is only responsible for roughly 4 % of atmospheric carbon dioxide, and water vapor is still the dominant greenhouse gas.

    Perhaps, as the environmentalists believe, it's regretable that science has made the human population explosion possible. So let's bring back the four horsemen, eliminate 80 per cent of the population, and reintroduce the better, purer life of hunter-gatherers for the lucky few.

    Just to establish an endpoint, we could have an all out nuclear war.

Indeed, a recent article in Physics Today[1] suggested that most earlier estimates of the severity of nuclear winter were underestimates.

    And there's more...

    "People have imagined that if we stopped emitting carbon dioxide that the climate would go back to normal in 100 years or 200 years," said study author Susan Soloman. "What we're showing here is that's not right. It's essentially an irreversible change that will last for more than a thousand years."

    In geological time 1000 years is almost insignificant ! An ice age, which would cover the UK destroying every village, town and city and displacing a population of 55 million (or thereabouts) would last 80,000 to 100,000 years.

    The warm inter-glacials have "been much shorter, lasting about 10,000 years. The last Ice Age or glacial period on Earth ended roughly 14,000 years ago." So, we're due another one !

    Also, how do we know that this "irreversible change" would not, actually, be good !

    Unlike humans, the planet does not maintain a "status quo" - it changes all the time. Rather than trying to force the planet to obey some "golden age" idyll, humans would be better to adapt with it (as they did in the past). When the ice age returns we'll all be nomads again !

    Of course, nomads are people of no-fixed abode so governments CANNOT tax them! Perhaps this is the real fear of our governments !

    BTW: I am NOT arguing for minimising human impact on the planet - I AM arguing that the planet is big enough to look after itself and ultimately will do so, no matter what the human race does.

    Big Deal (not)

    Humans - who have not been around for long - seem to think the planet was built for thier sole use and enjoyment. Selfish buggers, the lot of 'em.

    The planet does not need 'saving', the planet continually belches and gets rid of the scum on the surface. Global warming won't be 'irreversable', just that humans won't be around for the next big change of climate - not that they'd survive it anyway, delicate little things that they are.

    Is it a bird? Is it a plane? No! it's bloody big rock and it's the end of the world as we know it and I feel fine.

    Arse covering

    Seems to me that whenever it looks like the evidence won't support their models, the greenhouse gassers find excuses to shift the goalposts rather than admit that the evidence suggests CO2 does not drive global temperature. They do it when CO2 goes up and temperature doesn't, and now they are covering their arses in case CO2 drops and the temperature doesn't. So whatever the climate does they will say it is somehow due to anthopogenic CO2. This isn't science, it is hokum.

    Anonymous because I am a PhD Scientist with a hard (i.e. not "environmental studies" or some other mickey mouse course) science background and 30 years Energy and Environmental experience in academia, industry and consultancy, but publicly saying that you don't believe in anthopogenic CO2 driven climate change makes you a heretic against the current dogma and blows your career. I am not alone in keeping my head down because of the baying mob.

    @ Is the report available online?

    Of course it's bloody peer reviewed it's PNAS ffs.

    No it won't be available on line (to you), but your University library may have it, and if not you can ask your tutor to fill out and inter library loan request form for you.

    Let me get this right.

    "global warming is "irreversible" on the human time scale"


    Does that mean there's Sweet FA we can do about it.


    Lets all stop worrying about it happening then. If this *is* the case, we should be expending more effort on planning for a future that's going to be very different from the world we have now, rather than thinking like King Canute that buying a Toyota 'Pious' or any other hybrid/leccy vehicle is going to stop the water rising.

    "would go back to normal"

    But what is normal? The climate we are prepared to cope with in our modern lifes? The climate we built our houses* for and designed our ACUs?

    Or 'normal' such as in the past period of a couple of million years with hugh recurring changes?

    We are definitely not doomed, no matter how real or irreversible or human-made global warming is. It is simply a question of natural selection: those who are able to fit with the change will survive - be it animals, plants, human beings or politicians and journalists.


    *not exactly in the UK. British houses were surely built for the warm future climate which we will soon suffer from or enjoy; all depends on the individual attitude.

    Why don't people question anything anymore?

    Once upon a time, the atmosphere of the Earth was almost entirely CO2, there was no Oxygen at all. Then, as bacteria came along it changed. The Earth didn't explode or melt, it was fine.

    Before the last ice age kicked in, the level of CO2 was 17 times higher than it is now, and guess what, it didn't blow up then either.

    If CO2 affected the temperature then the IPCC, NOAA or the BBC would be able to show a graph that illustrates this, but as it doesn't, they can't. Occasionally it follows a similar path but the CO2 level lags behind the temperature.

    If man-made CO2 affected the temperature then again they'd be able to show a graph but they can't because it doesn't (10 years of cooling despite CO2 rising).

    So it can be illustrated that our CO2 emissions have no affect and that CO2 doesn't cause catastrophe to the planet so there's no need to save it.

    The IPCC warns that if we carry on for another 200 years (despite having run out of oil & coal long before that) then the sea level could rise 1M which would be terminally bad also (I'm sure it wouldn't take that long to build a wall in areas liable to flooding).

    Essentially they've no evidence it's man made, no evidence it can be stopped, no evidence it's really a problem. You don't need to be a scientist, you just need to look at what these people are saying to see how it just doesn't add up.

    I'm just glad that more and more scientists are distancing themselves from this.

    But the vast majority of scientists wouldn't know what climatology was like if it snuck into bed with them and gave them a BJ.

    re: Oh yeah that's right

    Please tell me where the scientists are here that are informing you? Because there aren't many and most of them are saying "It's real".

    What you have here mostly is a lot of people saying "Scientists say it isn't real, I read about it on the interwebs" and other nonscientists (I assume) saying "Scientists will make any shit up to get the result they want".

    So apparently if people come here only to be informed by scientists, they mistyped

    Why do you mention the 3%? That is irrelevant. All that means is that out of the 100% of CO2 that is taken up each year, 103% is released into the atmosphere.

    do you know what happens then?

    Year 1: 103% CO2

    Year 2: 106.09% CO2




    Year 20: 180.61112346694% CO2

    Of course it is irreversible. Humanity is too puny and irrelevant to have caused it and thus can't stop it either. We're not the huge influence that the religious movement called Environmentalism thinks we are.

  79. Anonymous Coward


    The "CO2 was 17 times higher than today" claim for the Ice Age is simply bogus - in fact it was lower than today, and the curve you asked for is well known, as is the cause of the lag in it (which is to do with the solubility in the oceans of CO2 varying as the temperature varies). Probably too complicated for you, but that has no effect on its validity

    You can go and live on Venus if you think CO2 has no effect; let us know how that works out for you.

    Are we? Or is that just an argument from personal incredulity?

    Remember, the earth's atmosphere is thinner in proportion to the earth than the skin of an apple.

    That's all we need to change, not the entire earth, just the extremely thin and tenuous gas that we all have to breathe.

    Yet another report/study predicting doom and gloom, based on studying facts, figures, other peoples work, whispered comments, runes and chicken entrails.

    Lets get things straight. Is there climate change ? Yes. Is there anthropogenic climate change ? jury's still out.

    If there is such a large concensus on everything being really bad and we need to do something, why isn't all the money being funnelled to these "scientists" who write the doom and gloom papers, not being given to physicists, biologists and chemists to work out a solution to the problem ? Like zero pollution energy production, tanks of hybrid algae (one of the larger consumers of CO2 I believe) and ways to collect and store (cheaply and efficiently) all the excess CO2.

    No, both sides of the argument are paying for reports to say whatever they want, with precious little actually being spent to find a solution.

    "Please tell me how many millions of years that CO2 was from?"

    Your missing the point, even if we turned *all* 100% of biomass & oil and coal from plant material to CO2, NOW, in zero seconds, the earth would still not suffer runaway global warming.

    Because when all the carbon that we're creating from plant material WAS in the form of CO2, the earth didn't suffer runaway global warming. i.e. there isn't enough CO2 from all plant material, petroleum, coal biomass etc. to cause runaway global warming.

    "Jesus, you'll grab anything to make it better, won't you."

    It is better, Global Warming may be real, runaway global warming certainly isn't.

    Wow, what a load o' horseshit

    Once again, I'm not a scientist. At least I admit it, unlike a lot of the posters here who submit their half baked comments here. Maybe if I claimed to be a scientists it would be worse, as some half wit even went as far as saying that no scientists (except of course computer scientists) produce anything of any use.

    I merely put forward that I tend to believe the published opinions of the Royal Society, the European Academy of Sciences and Arts, International Council of Academies of Engineering and Technological Sciences, the InterAcademy Council, the American Association for the Advancement of Science, the American Geophysical Union, the Geological Society of America, the Australian Meteorological and Oceanographic Society, etc etc etc

    (The list is long)

    ...not to mention the IPCC

    I read popular science journals and the web.

    Because I don't run with the herd of Reg readers I get flamed.

    Bugger that.

    Common element here - methane.

    Animals (and people) fart millions of tons of it every year, and methane is a considerably more effective greenhouse gas than CO2. Combine that with the methane from rotting garbage...

  92. dervheid

    Mark, You're so right!

    The sun IS the problem!

    NASA are looking for volunteers for a manned mission, it's objective is to put an object large enough between the sun and the earth to reduce solar radiation just enough to slow down the naturally occurring warming cycle at the present hospitable temperature range.

    I have it on good authority that you were put forward for this mission, but your skull was deemed to be to large and dense and it's shadow would plunge the earth and all its inhabitants into an immediate ice-age, forcing us to burn even more precious fossil fuel, and/or all the lentil munching eco-nazis just to keep warm.

    I'm afraid I'd have to reject any call to participate, as I'm far too busy adding copious quantities of CO2 and methane into the atmosphere. Perhaps you'd care to join me for a large curry this evening. I'll send my driver round in the Hummer. Best bring your coat, apparently it's going to get really chilly.
