NASA's Hansen Calls Out Obama On Climate Change

Hugh Pickens writes "Dr James Hansen, director of the NASA's Goddard Institute for Space Studies, who first made warnings about climate change in the 1980s, writes in the NY Times that he was troubled to read a recent interview with President Obama in Rolling Stone in which he said that Canada would exploit the oil in its vast tar sands reserves 'regardless of what we do.' According to Hansen 'Canada's tar sands, deposits of sand saturated with bitumen, contain twice the amount of carbon dioxide emitted by global oil use in our entire history. If we were to fully exploit this new oil source, and continue to burn our conventional oil, gas and coal supplies, concentrations of carbon dioxide in the atmosphere eventually would reach levels higher than in the Pliocene era, more than 2.5 million years ago, when sea level was at least 50 feet higher than it is now.' Hansen says that instead of placing a rising fee on carbon emissions to make fossil fuels pay their true costs, leveling the energy playing field, the world's governments are forcing the public to subsidize fossil fuels with hundreds of billions of dollars per year."

    The level playing field for carbon neutrality is a sham designed to do nothing more than transfer wealth from first-world economies to third-world economies. In the process, all you really do is set a soft cap on carbon emissions without reducing actual dependence upon fossil fuels.

    We can achieve the same goal of reducing carbon output by instead investing that money into first-world research and development of alternative fuels. Full implementation then eliminates carbon emissions altogether, a goal which can't be achieved by market-based carbon neutrality alone.

      Actually, I think the idea is to put a monetary cost on things which currently have no cost, namely, emission of gasses which may have a negative effect on climate. I think thinking that there is some conspiracy here is kind of ridiculous. One side wants to implement government regulations to reduce carbon emissions. The other side believes the market will solve these problems. So we arrive at a compromise where we attempt to achieve our goal (reducing emissions) by using the market (make it have a cost). This seems entirely reasonable. Why shouldn't we attach a cost to pollution?

      Which would be largely meaningless for several reasons. First, the world is currently using almost as much oil as can be pumped out of the ground at maximum rates. There is no longer any significant slack in the world's oil supplies while at the same time there are billions of aspiring consumers in both India and China who are right now in the process of acquiring all of the habits of a western style consumerist lifestyle. This means that any slack in the oil market generated by American or European cutbacks, due to carbon pricing or whatever, will be almost immediately taken up by consumers and industry in China and India. What will be the result of this policy? American and European economies are crippled by higher energy taxes while at the same time no less carbon is emitted because India and China are now burning whatever oil we don't. In fact, it would probably lead to overall worse emissions because vehicles in China in India tend to be older and less efficient designs which belch huge clouds of greasy black smoke from their tailpipes and produce large quantities of photochemical smog. Second, selling energy taxes is like selling austerity and we've all seen how well austerity sells to the public in Europe as a result of the financial meltdown. People really hate being asked to make do with less, especially when government policy forces it upon them.

      The difficulty of building nuclear power fast has been exaggerated with the help of a misleading presentation technique I call “the magic playing field.” In this technique, two things appear to be compared, but the basis of the comparison is switched halfway through. The Guardian’s environment editor, summarizing a report from the Oxford Research Group, wrote “For nuclear power to make any significant contribution to a reduction in global carbon emissions in the next two generations, the industry would have to construct nearly 3000 new reactors – or about one a week for 60 years. A civil nuclear construction and supply programme on this scale is a pipe dream, and completely unfeasible. The highest historic rate is 3.4 new reactors a year.” 3000 sounds much bigger than 3.4, doesn’t it! In this application of the “magic playing field” technique, there is a switch not only of timescale but also of region. While the first figure (3000 new reactors over 60 years) is the number required for the whole planet, the second figure (3.4 new reactors per year) is the maximum rate of building by a single country (France)!

      A more honest presentation would have kept the comparison on a per- planet basis. France has 59 of the world’s 429 operating nuclear reactors, so it’s plausible that the highest rate of reactor building for the whole planet was something like ten times France’s, that is, 34 new reactors per year. And the required rate (3000 new reactors over 60 years) is 50 new reactors per year. So the assertion that “civil nuclear construction on this scale is a pipe dream, and completely unfeasible” is poppycock. Yes, it’s a big construction rate, but it’s in the same ballpark as historical construction rates.

      How reasonable is my assertion that the world’s maximum historical construction rate must have been about 34 new nuclear reactors per year? Let’s look at the data. Figure 24.14 shows the power of the world’s nuclear fleet as a function of time, showing only the power stations still operational in 2007. The rate of new build was biggest in 1984, and had a value of (drum-roll please...) about 30 GW per year – about 30 1-GW reactors. So there!

    We aren't going to stop using whatever kind of oil we find, obviously. So we need to clean up this carbon out of the air. Classically, nature does this for us but we seem to have overloaded that mechanism. Trees have been the acme of biological agents for scrubbing the air, but we need a new one.

    We need a plant that grows fast, and by growing and producing it's seeds/fruit it consumes a lot of carbon. We have just such a perfect candidate, but leave it to politics to forbid it. I am talking about hemp. Hemp has the bulk and the seed production that will yank carbon out of the air by the scruff of it's neck. It grows small tree tall in a single season and it sucks so much carbon that the seeds are teaming with a hydrocarbon.

    Historically, it's a weed that farmers hate because it leaches soil quickly of nutrients. To me this isn't a problem with modern hydroponics. We have plenty of recyclable products and our own sewer to feed a hydroponic system that would feed these hemp plants. It would process waste and carbon into a plant that has more uses than I can count.

    With hydroponics, lots of real estate that is worthless to build on can be used for hemp patches, piping a rich slurry to feed them, processing our own waste. We don't need to cut into crop lands, hence the "leaching" effect can be controlled.

    Of course there are roadblocks to this solution. The cotton industry has been an enemy of hemp, mostly out of fear that it will replace them. Of course we have the anti-drug crowd that will insist that hippies are going to smoke it. Counters to that are that is creates new industry and innovations from a very "green" resource that is not only renewable, but it helps scrub the air. Everyone wins. Except for the hippies who tried to smoke it, who are wreathing in agony from a "ditch weed" headache.

      Actually, while trees and other land-dwelling plants certainly help, just like with oxygen production most of the heavy lifting is done by the oceans - atmospheric CO2 dissolves in the water and gets used by diatoms, algae, and plankton, which then die and carry their sequestered carbon to the ocean floor.

      And when it comes to hemp roadblocks, don't forget the lumber industry which wouldn't be very profitable if hemp replaced wood waste for paper making and other uses, and the pharmaceutical industry which is none too pleased about the panacea of useful compounds found in hemp. I hadn't heard of the nutrient-leaching problem, but I doubt it's much worse than with cotton or other soil-destroying crops and could probably be handled similarly, with fertilizers or intelligent crop rotation. Talk to the folks currently farming it in other countries, I'm sure they've got it all worked out.

    Depending on how you account for these factors, you reach very different answers about who should pay for carbon emissions.

    The obvious answer to the question "who should pay for emissions?" is "the people who did it". You are, for some reason, attempting to lump in lots of other environmental issues to the one of CO2 emissions. When we regulated SO2 emissions, we just did it - we didn't wait until we had figured out how to handle deforestation or population growth in Africa, or how to somehow "correct" the effects of colonialism or emigration in Europe thousands of years ago.

    If you don't think that the emitter should pay, then who should? The rich? The poor? Everyone pay an equal share? If so, how do you account for different salary rates in different nations - should everyone pay an equal proportion of their income? It is ridiculous to suggest that, say, Africans with their average income of $315 a year should have the same responsibility towards paying this cost as Westerners who earn many times more, especially when it was the Western nations who contributed most to the increase in co2 levels:

    The major countries with the biggest per-capita emissions are Australia, the USA, and Canada. European countries, Japan, and South Africa are notable runners up. Among European countries, the United Kingdom is resolutely average. What about China, that naughty “out of control” country? Yes, the area of China’s rectangle is about the same as the USA’s, but the fact is that their per-capita emissions are below the world average. India’s per-capita emissions are less than half the world average. Moreover, it’s worth bearing in mind that much of the industrial emissions of China and India are associated with the manufacture of stuff for rich countries.

    So, assuming that “something needs to be done” to reduce greenhouse gas emissions, who has a special responsibility to do something? As I said, that’s an ethical question. But I find it hard to imagine any system of ethics that denies that the responsibility falls especially on the countries to the left hand side of this diagram – the countries whose emissions are two, three, or four times the world average. Countries that are most able to pay. Countries like Britain and the USA, for example.

    Historical responsibility for climate impact

    If we assume that the climate has been damaged by human activity, and that someone needs to x it, who should pay? Some people say “the polluter should pay.” The preceding pictures showed who’s doing the polluting today. But it isn’t the rate of CO2 pollution that matters, it’s the cumulative total emissions; much of the emitted carbon dioxide (about one third of it) will hang around in the atmosphere for at least 50 or 100 years. If we accept the ethical idea that “the polluter should pay” then we should ask how big is each country’s historical footprint. The next picture shows each country’s cumulative emissions of CO2, expressed as an average emission rate over the period 1880–2004. Average pollution rate

    Congratulations, Britain! The UK has made it onto the winners’ podium. We may be only an average European country today, but in the table of historical emitters, per capita, we are second only to the USA.

    If the trees and temps don't jive now, then why is it valid to say they jived a thousand years ago?

    If you throw out the enitire TR proxy the results are virtually the same as only throwing out the divergent part. This in itself strongly suggests the "good" part of the proxy does indeed correlate well with the average of the other proxies wich in turn correlate with instrumental records and/or isotopic 'clocks'. As you say the TR proxy diverges from the instrumental record after the 1950's, and it's unknown why this is so, but it doesn't change the reconstruction in any meaningful way.

    You should always consult the primary source, especially when the subject is AGW. If you haven't read the hockey stick paper and it's 2005(?) follow up, then do so, they list the proxies and discuss the tree ring problem. Proxy data sets can be found at Nasa's paleoclimate data repository. I think you'll find there are more than a "few samples" in the 3377 TR data sets they have on their books. Yes, data SETS, not data points.

    Speaking of sources, you may want to try running your bullshit detector over the primary source that led you into this well known cul-de-sc of irrelevant trivia.
