Melting Arctic Ice Has Consequences

OriginalArlen writes to tell us about some compelling global warming coverage in the Washington Post. First there is an article about a study indicating that melting Arctic ice is threatening polar bears with extinction. The article quotes an environmentalist: "This study is the smoking gun. Skeptics, polluting industries and President Bush can't run away from this one." And the polar melting is opening new shipping lanes. The second article details a trip late in October through the Northwest Passage by a Canadian icebreaker. Never before in history could this trip have been accomplished so late in the year; ice would have choked off the passage. Estimates of when the passage might be navigable by commercial shipping range from 2020 to the end of the century. The indigeneous people are not looking forward to this development.

    On both sides.

    This has been presented before, and debunked before. This study shows that while ice is thinning in some parts of the arctic, it is thickening in others and the temperature change isn't uniform.

    It also shows that the majority of polar bear populations are steady, with an equal number on the increase and decrease.

    That shipping lane has been there before, and guess what -- there were polar bears around back then. Amazingly enough, polar bears aren't the hot-house flowers these people are making them out to be.

    The climate is changing, that is for certain. The only thing more certain is that politicos and people who want gov't grants are going to exaggerate and hype every little anomaly beyond belief in order to garner attention and eventually money.

      How do you tell science and political bullshit apart, other than by whether you like the result?

      It happens that the "report" you quote is scientifically incoherent. I don't know much about polar bears, but I am very familiar with sea ice trends.

      Arctic sea ice summer extent minima are rapidly retreating, and the best evidence is that perennial ice has shrunk by 40% ion the last forty years. It is reasonable to expect that all the perennial Arctic sea ice will go away in this century, both by extrapolation and by careful consideration of the thermodynamics and radiation budgets involved.

      Real scientists talk about one issue at a time, and their opinions have a logical consistency rather than a political one. No one who is an expert on polar bears is an expert on sea ice mechanics.

      The statement about Antarctica is a particlar howler.

      "Moreover, while sea ice has decreased in the Arctic, it has remained relatively constant (or even increased slightly) in the Antarctic since 1978."

      It's true enough but completely irrelevant. Have a glance at a globe. It might be worth considering that Antarctic sea ice has completely different origins than Arctic sea ice. If Antarctica melts, what happens to southern summer sea ice extent?

      And why should polar bears care about the Antarctic anyway?

      The paper you quote comes from a group that invariably highlights evidence against global warming and minimizes evidence supporting it. I don't know who funds it, but I have run into it before. I promise you it is not considered a scientific source; but go ahead an check the citation index and prove me wrong.

      So, as someone who knows some of the scientists, who seem to me to be very serious people, I would say you have your bullshit and your science swapped.

      I'm sure you won't take my word for it, but consider this. How, exactly, would you know?

      I am an environmental scientist. As such I cannot be held responsible for what any political party does.

      The word "environmentalist" makes me cringe, though not as much as the word "anti-environmentalist" does, I'll admit. I am just doing my part to explain the difference between the facts and the noise that is injected by people with many billions of dollars of fossil fuel assets that they are motivated to protect.

      However, you are right that I do dismiss the contemporary crop of "global warming skeptics".

      I dismiss "global warming skeptics" because they are incoherent and wrong and well-funded by non-scientific interests. If there weren't a lot of money at stake the skeptics would vanish. They don't have a coherent theory. If they did, they would get a hearing in scientific circles. They don't, so they are busy running around looking scientific for the press, and taking in people who are philosophically uncomfortable with the implications of the science.

      Fifteen years ago there were interesting arguments against taking action. Now all the arguments are based on wishful thinking. I haven't seen an argument against restraining net carbon emissions with any "merits" for some considerable time, and it is not for want of looking.

      I am sure you would not like some of my political opinions, but I am not discussing my politics in this thread. You are entitled to your own opinion but you are not entitled to your own facts.

    The USA sweated this year through its hottest summer in 70 years, with temperatures not seen since the Dust Bowl of the 1930s, according to a government report.

    From June 1 to Aug. 31, as summer is defined by the National Climatic Data Center, the continental USA had an average temperature of 74.5 degrees, based on readings from hundreds of weather stations nationwide. It was the second-hottest summer temperature the government has recorded since it started keeping track in 1895. The only one warmer -- by about two-tenths of a degree -- was in 1936.

    Ok, seriously, what made it so hot back in 1936? Was it just a natural occurrence, or was it man made way back then?

    Simple.

    The US has entrenched technology that will take decades if not centuries to phase out; coal and oil fired power plants, internal combustion engines for automobiles, oil, natural gas, and coal heat for homes, and so forth.

    China has a great opportunity to go electric across the board from the get-go, using nuclear power and solar power. Their infrastructure is still immature, and as such there is no huge investment in existing power to speak of. I'm sure that the folks working in agriculture are still using wood, peat, or coal for heat, and have not spent thousands on oil-fired central heating systems for their homes; why not go electric from the beginning? Then emissions controls can be centralized, and their choice for petrol-vs.-nuke-vs.-wind can be made now. What's more, if so-called environmentalists who really are all about "NIMBY" can't block this development like they can here with their bleeding heart "think of the children" whining.

    Because while the US may have higher emissions per-capita, their ratio of emissions vs energy produced is a lot LOWER than a country like China. Now, while there is a bit of room for decreasing energy consumption in the western world through things like more efficient fridges and light bulbs, the fact of the matter is that any modern society is going to require massive amounts of energy. The US or any other modern country could never bring their emissions as low as China simply because much of China doesn't even have electricity yet. As China continues to grow and modernize itself, we'll all be VERY lucky if they manage to keep their per-capita emissions below US levels. And the most likely way to make that happen isn't by taxing the shit out of western business to pay for "emission control", but by putting more funding into researching alternative energy generation and storage methods. That way, by the time China's industry goes into full swing, we'll have alternatives to offer them instead of having them rely on coal and oil. Kyoto's pretty much useless. You want to reduce global emissions? Set realistic standards for countries to meet, and then impose penalty fees if they don't meet them. Then take those penalty fees and funnel them into alternate fuels research. Fund everything from solar cells and more efficient batteries to hydrogen engines, to nuclear plants and fusion research. Hell, since the UN is pretty good at administration (if nothing else) get them to set up a research facility and extend invitations to the leading scientists in those fields. With all western nations participating you could have nearly unlimited funding. The modern (and more productive) version of the Manhattan project. Kyoto right now is nothing more than a wealth-redistribution campaign to move funds from western nations to the third world, and help us feel like we're "doing something". If we really want to reduce emissions, let's get serious.

    I find it funny that a story like this with the typical bash bush mantra has come out and the conslusion is the "Bush cannot run away from this one".

    The fact is that bush hasn't run away from environmental issues at all. What he has done is not fall for every quick fix and explanation and adopted some "we need to get rid of the internal combustion engine by tomorrow" attitude. As others have or will point out, the current solutions are more of a economic redistribution of wealth and weakening of national stature then a fix for global warming.

    Bush has created or secured wetlands habitat, has increased the fuel econemy rating for a good portion of vehicles on the road. Some SUVs are no longer exempt from the cafe standards and are required to get better mialage now. He has invested millions into alternative and green energy on several different initiatives plus reauthorized initiatives started under previous administrations.

    I know this stuff doesn't count because Bush is evil and it doesn't fit our bashing campaign right now. Especially when we need him to look bad so close to an election cycle so the opposition can take a department of the government over to them. But what this really says is that all the "opponents to global warming" are seemingly more correct when they claim ulterior motives from the "the world is going to end" global warming crowd. I can understand some people just not being informed. But statements like yours show and agenda that can be placed into a number of conspiracies that will retard the development of any future works to help curve global warming. Do we really need something like that? We have a whole group pf people against Kyoto because it places what some people claim to be unrealistic expectations on developed countries while the solution if it cannot be met is to "pollute in a less developed country" or "pay less developed countries not to develop in a way that pollutes".

    People take that to mean "forced redistribution of wealth" and point to people like you ignoring what little the president has done for the environment then look at their friends and say "see what i mean, they are trying to buffalo you for a one world order, socialist world order, or something worse"(worse being the trying to move all America's industry across seas so to make an economic blockade effective and force legislation on us in the way we do other countries).

    Keep giving them ammunition and watch how little gets done.
