UN Report Downgrades Human Impact on Climate 378

GodInHell writes to mention an article in the Telegraph, stating that man's impact on the environment has been 'downgraded'. A UN report has found that our species has not had as large effect on climate change as was previously thought. The average temperature is still due to rise almost 5 degrees C in the next 100 years, bringing drastic changes in weather patterns. From the article: "The panel, however, has lowered predictions of how much sea levels will rise in comparison with its last report in 2001. Climate change skeptics are expected to seize on the revised figures as evidence that action to combat global warming is less urgent. Scientists insist that the lower estimates for sea levels and the human impact on global warming are simply a refinement due to better data on how climate works rather than a reduction in the risk posed by global warming."

        I would be very concerned here in Hull, UK if sea levels rise as the River Humber is tidal and some areas of the city and nearby area are below sea level. London would have similar problems with a rising in the level of the Thames. There loads of other areas around the world which would suffer similar problems.

      Well, who knows. People today seem to be almost solely fixated on "global warming" and carbon dioxide emissions. There are many, many other pollution problems--sulfur dioxide / acid rain being one of them. China for instance today has huge sulfur dioxide emissions, roughly comparable to the US 25 years ago before we got good about it.

      It's a difficult position, seeing as I saw one estimate that in terms of co2, China would overtake the US in roughly 5 years at current rates. (I'm not sure how accurate that is). It's truly got to be a global initiative, but one that doesn't do more harm than good. Plans like Kyoto makes huge exceptions for countries like China and India. This is of course good for them, not so good for everyone else.

      In short, I have no idea what's going to happen :p

          For example SO2 causes acid rain which damages vegatation releasing CO2. It's far to early to tell whether increasing SO2 emissions will help or will just cause a lot more damage. It's an interesting theory but it's still not well understood.

        Yeah, you know, you kind of skipped something important in this whole 'fairness of polluting' issue. You know, our (I'm American) economy raged when we didn't care about dumping shit in the environment. And it's still pretty evident that green products cost more (not always but usually). In fact, carbon neutrality would almost certainly raise the price of your product and a carbon tax would stagnate the economy at least a little.

        So, when we chastise other nations for doing what we did 25 years ago, we may be hobbling them somewhat in the international market if we force them not to do that. I mean, look at the great infrastructure and products that we've produced while destroying the environment. You have to admit that it's given us an upper hand.

        And this doesn't just apply to chemicals and gases, remember our 'save the rain forest' campaigns? Well, who was campaigning us to stop logging in North America (pictures on the right side [wikipedia.org])? We've literally deforested much of the United States and benefited from it quite a bit. Who's to say we're not completely hobbling the economies in 3rd world countries that are attempting to tap their nation's natural resources of wood?

        I guess in the end I just ask that you don't tell a nation not to do something but offer them an inexpensive or practical alternative ... or, hell, maybe even compensate them for lost wealth? I don't know, I'm not an economist and I'm sure I'm going to get a lot of negative replies for defending China or people cutting down rain forest for land. Oh well.

          You are right on. This is an angle that the environmental movement has not yet come to terms with. The gorilla in the room is not the carbon production of the currently industrialized countries, it is the carbon production in the near future (20-50 years) of the currently inductrializing countries, which are far more populous. Most of the rhetoric of the global warming movement has been centered about modest lifestyle changes in developing countries: smaller cars, power conservation, and subsidizing carbon neutral energy sources. These are easy changes to make for the average westerner: They don't strongly impact our quality of life. Too bad the the carbon withheld from the atmosphere due to these changes is so small compared to the quantities that will be released a generation from now from the populous countries that are currently industrializing.
              For the global warming movement to address the gorilla in the room, they would have to ask people in China and India to forgo that first refrigerator, automobile, computer, tractor, or paved road. And that is not a morally defensable or politically feasable position. Until the global warming movement faces up to this fact their efforts in the developed world are just a sideshow.
              I think human carbon emmisions contribute to global warming, and that human carbon emmisions will explode in the next 50 years due to the industrialization of populated countries and due to increasing carbon emissions from alternative oil sources. (Coal gassification, tar sands, extra heavy oil... all of these release a ton of carbon just to produce, before they are even burned!) Greens should be lobbying the governments of devloped countries hard for r&d into affordable carbon neutral technologies that can be scaled to the meet to enourmous quantities of energy that the developing world will soon be demanding. The only tech. I know of that is carbon neutral, sufficiently scalable, reasonably affordable, and could be implemented on a massive scale just one generation from now is nuclear fission. If greens aren't advocating for this than I don't think they are serious about putting a major dent in global warming.

          1) it's been more than 25 years ago...

          3) what we were doing was the pinacle of high tech at the time. Pollution controls didn't exist, until we invented them.

          Today, the Chinese government certainly knows the cause and effects of pollution, know the technology exists to significantly reduce the problem, and yet they don't bother to use it, anyhow, usually for reasons of national pride (they'd have to buy this tech from foreign companies, instead of using extremely dirty domesticly made products).

          So China shouldn't have to pay for their own pollution or pollution controls? Somebody else should pay for it, for them?

          Not likely. China is now quite wealthy, they just chose not to control their pollution, because nobody has forced them to do so. Threaten to ban Chinese imports if they aren't produced "green", and they'll straighten up real fast. Of course I realize the political will to play chicken with cheap Chinese junk just isn't there, but that's besides the point.

        The water doesn't have to come from glaciers, as long as there is precipitation in the mountains there will be water downstream. Global warming would only result in less arable land if it makes the world dryer overall, but most simulations show the world getting wetter if it gets hotter.

          Rain is often seasonal. Part of the problem in the Western US, is that if there is not a sufficiently cold winter, snow pack in the mountains melts early and then in the dry season (summer), there isn't enough water flowing down the rivers because it already flowed away. Summer BTW coincides with the growing season. Water and ice are not really the same thing -- sure it's all water, but snow is water storage and rain is water runoff.

      You're missing the "global" in global warming. Just because the earth as a whole is getting warmer and the ice caps are melting, it doesn't necessarily mean your backyard is getting a tropical climate. For some regions the long-term prognosis is that it will get a whole lot colder -- for example, western Europe if the gulf stream shuts off.

      One reasonable inference we can make is that weather will get more violent and less predictable, simply because we're pushing more energy into a system that exhibits chaotic behaviour. So expect more freak weather -- and on a local, short-term level, that's could just as well be snowstorms as heatwaves.

      There could be no better argument for avoiding large-scale experiments, then. But we do know that CO2 levels are rising, that it's not coming from living organisms, and that the pattern of change (warmer lower atmosphere, cooler upper atmosphere, warmer nights) matches the effects physics says to expect from CO2.

    And it's not pretty either. Even if you ignore global warming or global climate change for a moment, you just have to step outside in any of our urban centers, look at the sky and take a whiff. Of course we're hurting and changing the environment. That's the real shame of it. I happen to work with an environmental scientist and he says the number one bad thing that everyone is ignoring is the short-term, immediate affect on our health. We're slowly killing ourselves in our own pollution.

    Whether the long-term effect of what we do is 10 degrees of warming, 5 degrees of warming, or even 5 degrees of cooling, we're still have a pretty drastic affect on the poor earth. Apparently, there is new research coming out all the time (and not from the grand right-wing conspiracy) that global warming isn't happening as fast as some think. But does it really matter that it's slower than we thought? We still have to confront the same issues. Net carbon increase, particulates, and nitrous oxides, all of which damage our health, as well as the environment.

        The main cause of cancer is people failing to die of other causes first. Second, is whether the person smokes or not. Pollution along with diet is further down the list.
      • The reason cancer is such a large killer in industrialized nations (and it should be noted that heart disease and stroke are larger killers) as opposed to the 3rd world is that it is in the 3rd world you die of something else first. Cancer is by and large an old person's disease. It simply doesn't affect the young very often. Well when you are dying of Malaria or the like first, cancer rarely has a chance to strike. Also, due to poor medical care, if you do die of cancer it's usually not chalked up to that

      Do you know the greatest cure for that?

      Economic growth. As we get richer we are less willing to tolerate pollution and can afford to pay for the removal of pollution. (It's just the growth of the NIMBY movement writ large.)

      Compare, say, Taiwan and China who are at lower levels of economic development with big US or UK cities. The US and UK cities are immesurably cleaner. Furthermore, these same US or UK cities that you are complaining about are much cleaner than they were, say, 100 or even 50 years ago. Why do you think countries moved to unleaded petrol? Because they could afford to. Lead is cheaper as an additive, but the side effects in terms of smog are pretty dire. Consider, even, the move to diesel as a more environmentally friendly fuel. It happened because we could afford to develop high efficiency diesel engines and low-sulphur fuels.

      So people are not ignoring pollution - its just that they prefer to have functional hospitals and schools and police forces. And when they can afford to they'll get rid of as much pollution as they want to. And when enough people care enough about greenhouse gas emissions to actually pay for it in their electricity bill (using the alternative energy suppliers that seem to be popping up in many countries) they will switch.

Our entire economic infrastructure is based on ever accelerating consumption of oil, metals, water, and timber, all of which are being used faster than they can be replenished. The faster we consume, the harder it's going to hit us when we finally run out of all the things we need.

    Last time I checked, environment was very different from climate change.

    Man has undeniably had a huge effect on the environment; making species extinct, over fishing/hunting other species to the point of extinction, using up the Earth's non-renewable fuel sources - wood, oil, coal, building over huge chunks of the planet, not to mention the various poisons, dioxins and various nuclear stuff we throw into the atmosphere, ground and oceans.

    In this case the submitter has his facts wrong. The Telegraph article linked mentions only climate change, not man's impact on the environment as a whole. Sorry to nitpick, but I see those words being substituted for each other way too much now. You can argue all you like about climate change, but man's impact on the environment as a whole is proven.

    Let us imagine that one night you wake up and discover that your house is on fire.

    You dial 999 (or 911, if you're American) and ask for help: the nice despatcher tells you that the police department were watching your house and they're pretty sure there was no arsonist.

    Do you think, "oh, it's not an arson attack," and go back to bed?

    (Or do you evacuate the burning building anyway, and wait for the fire service to get there?)

    Here's the point: the house is on fire. It doesn't matter why it's on fire, in the first instance; the fire is an emergency situation and needs to be dealt with regardless of the cause.

    And by analogy, it doesn't matter whether the observations of climactic change are attributable to anthropogenic warming or to some other cause, or to a mixture of causes -- if we don't take action we're going to be in deep shit.

      The real case:

      Someone tells you that, if you don't take drastic action right now, your house will catch on fire some time in the next 100 years. A while back, the same guy was telling you the house was going to be flooded due to the same actions that will now, supposedly cause that fire.

      The current "fire prediction panel" has downgraded the actual fire risk, to boot, since all of their previous predictions of fire have not come true, and it turns out that some of the evidence they were using to predict the fire was actually made up. It seems that the computer model they were using also predicts fire if you put random noise into the input hopper.

      Meanwhile, the people who scream most about how the fire will destroy the house are going to bed while smoking, while insisting that you need to turn out all of your lights and sleep on the floor.

      Let's try a better metaphore. Let's say you wake up one night and think that because your house is made of wood, that it might catch fire if some burning embers from a lit cigarette fall on it, after all, that's how smokey the bear says forest fires get started.

      So you institute an imediate policy againsts lit cigarettes of all types within 100 yards of your house and comission some studies on house fires.

      Over the years, your studies begin to reveal that while cigarettes can cause a fire, it's not the most likely cause.

      Do you continue your capaign against cigarettes or do you revise your protection models.

      The point is, your house isn't on fire, it's at risk, but effective safety is knowing which risks are most important to minimize.

      Also the point is that analogies are shitty, why don't you just say what you mean, which is, despite the fact that the study shows human impact is lesser AND shows that newer understandings demonstrate a reduced risk, you would rather blindly continue with current policies as is, much like the few crackpots who completely deny global warming want to continue with their current policies as is.
  • They're dialing back predictions of human impact by 25%. That is less than the known uncertainties in the range of possible predictions.

    Then, the revised forecast includes one scenario of a 4.5 degrees C rise in average global temperature. That's still well into the severe range.

    However, Julian Morris, executive director of the International Policy Network, urged governments to be cautious. "There needs to be better data before billions of pounds are spent on policy measures that may have little impact," he said.

    Of course, they don't bother to say who these people are, or the fringe views they hold. From wikipedia [wikipedia.org]

    In November 2004, IPN released a report claiming that "climate change is 'a myth', sea levels are not rising and Britain's chief scientist is 'an embarrassment' for believing catastrophe is inevitable." It called "the science warning of an environmental disaster caused by climate change ... 'fatally flawed'" and contested predictions that the global sea level would increase by a meter over the next century, saying that "sea level rises will reach a maximum of just 20cms." Moreover, the report listed some benefits of global warming, including "increasing fish stocks in the north Atlantic and reducing the incidence of temperature-related deaths among vulnerable people." The British newspaper The Guardian claimed that IPN had received $50,000 from ExxonMobil, which "list[ed] the donation as part of its 'climate change outreach' programme."

    The IPCC has been forced to halve its predictions for sea-level rise by 2100, one of the key threats from climate change. It says improved data have reduced the upper estimate from 34 in to 17 in.

    Once again, newpapers show that they have absolutely zero knowledge of science or statistics. Tell me, if I do two experiments to try and find the radius of the earth, and find the first time that my results are 6,370 +/- 3210 km, and the second time that my results are 6370 +/- 10km , is this 'junk science' because my upper bound has dropped by 33%? Of course not. All this quote shows is that their calculations are getting more precise. If you want to show that they were wrong in their last report you'd have to show a large change in their AVERAGE value, and since the sensationalist reporter here didn't bother to even quote it, there's nothing we can say.

    By the way, if you want to, you can see projections of sea level from the 2001 report online [grida.no]. The sea level rise for several different scenarios [grida.no] is given in the graph on the right. The overall error bounds are larger because they combine all the data for these scenarios, which are vastly different in their assumptions about economic, technological and population growth in the next century.

    Most often when a reporter puts a quote at the end of the article, that quote presents the conclusion the reporter would like the reader to take away. In this case, it wasn't even worth the reporter's time explaining who in hell the "International Policy Network" is, let alone why an opinion from them should be pertinent here. Note also that the article above that details a lowered prediction of sea level rise precisely because there is now better data. So Mr. Morris's comment is a non sequitor.

    Okay. So, the article says that in 100 years, the sea level will rise by up to 17 inches. Now, I live in Minnesota, the Land of 10000 Lakes. My family's cabin is on a lake north of wear I live, and we have had fluctuations of, like, one or two meters over the last twenty years. Guess what? When the level goes up, we move the dock up. When it goes down, we bring the dock back down. Sometimes we have more beach, sometimes we have less. It's not really that big of a deal.

    In the ocean, you already have tides and storms and such. I think that 17 inches would have even LESS of an impact in the ocean, since those other effects already have to be accounted for when finding a good spot to put a dock or a house.

    And, if we have 100 years to deal with this, I really don't know why we don't just take a couple billion dollars or so from one of these studies and invest it in some high-growth investment market and just let compound interest give us the solution? If Kyoto would put any significant pressure (like, at least %1) on the $13 trillion American economy, we could just go without Kyoto and put that $130 billion a year for twenty years and then pay every islander in the world a $5000 stipend every year forever from the interest earned? I mean, I could survive on $5000 a year, and I live in America! That amount of money would allow one to pretty much live in luxury in a third world country. Am I the only one who thinks that Kyoto would put more pressure than just 1% on the American economy, assuming it was actually followed?

    If a sea level rise of 17 inches is really one of the biggest problems of global warming, then it sure doesn't make me that worried (especially since Minnesota is land-locked and, hey, it gets pretty cold here in the winter...).
