Eastern United States vulnerable to climate change

Time to get out of the Eastern United States? A study to be published in the Proceedings of the National Academies of Science tries to quantify the relative risk of climate change using something called a “socioclimatic” risk factor. As always, the redder the worse. A look at the paper would no doubt be more illuminating, but for some reason, press releases about PNAS papers come out way before the papers actually become public. China is in bright red all the way, India in a rather bright orange. Where I live, the Eastern United States, is a nice beet red. No doubt, the unprecedented drought the South is experiencing right now is a nice big red signal.

Interesting stuff, though the actual paper will tell the story. Any technique that tries to integrate all the complex scientific, social and economic variables of climate change into one number is bound to have a flaw or two. But such a metric is useful for estimating relative risk, as the authors themselves say.

He added that the study does not address the absolute degree of impact or risk.

“This study illustrates exposure of one nation relative to another,” Diffenbaugh said. “Thus, it is important to note that a country low on the relative scale could still face substantial risk.”

    As the developed world vacillates, Indian villages go under

    Sea gobbles up five villages in 15 years- Hindustan Times

    On Wednesday, a big tidal wave hit the coast in the Satabhaya area of Kendrapara district. It swept away homes and inundated farmland. But was no exception.

    Tidal waves like this one have been a regular phenomenon in the area. In the past 15 years, the sea has come inside the land by 2.5 kilometers. And as many as 600 families are leading a precarious existence in the Satabhaya and Kanhupur areas due to this phenomenon.

    Satabhaya, as the name suggests, once boasted of seven adjacent villages. Five of them have now been completely devoured by the sea. Thirteen families lost their homes to the surging waters on Wednesday. There was, fortunately, no loss of lives.

    Well, the consequences are set for the next 20 years, but still no action from the US on global warming which will determine how things are 50 years from now, I am not holding my breath.

  • Trade Agreements Create Pollution Havens

    Interesting paper out of the Berkeley Global Economy Journal
    Trade Agreements and the Environment: An Industry Level Study for NAFTA
    Raymond MacDermott. Global Economy Journal Volume 6, Issue 3 2006 Article 3

    We find strong evidence of both the pollution-haven hypothesis and the positive impact of the NAFTA on FDI.  In addition, we find the trade agreement exacerbates the pollution-haven effect.  That is, the incentive to invest in countries with weak environmental regulations is greater under a trade agreement such as the NAFTA.  Surprisingly, stronger evidence of this effect is found in lower polluting industries than in higher polluting industries.

  • PFOA Precursors to be phased out

    Leftovers may explain perfluorinated compound puzzle:

    See my earlier post about this. Looks like the EPA did want the companies to phaseout not just the PFOA, but the precursor compouds as well, and according to this article, quite a bit of progress has been made.

    Eight companies have pledged to slash releases of several perfluorochemicals at their operations around the world, EPA announced on March 2.

    Arkema, Asahi, Ciba, Clariant, Daikin, DuPont, 3M/Dyneon, and Solvay Solexis have agreed to reduce emissions of perfluorooctanoic acid (PFOA), its longer chain homologs, and compounds that can degrade into PFOA, EPA said. The companies will also reduce levels of these compounds in their products. Responding to a challenge EPA made in January, the eight firms volunteered to cut industrial releases of PFOA as well as amounts of the chemical in products 95% from 2000 levels by 2010 or earlier. The companies also pledged to work on eliminating releases and content of PFOA in products by 2015.

    Here are the individual companies’ commitment letters. They all loudly proclaim their commitment to reduce PFOA levels in their products, not quite so universally unequivocal on the precursors… I need a lawyer to parse some of the language. 3M, for instance, says that they do not “manufacture” the telomers’, which is not the same as saying they do not use them. Solvay Solexis, is extremely straigtforward and agrees to the EPA conditions in a letter actually written in plain English! Dupont, good letter too. Let’s see how this situation plays out, outright elimination in 10 years seems nice, which leads me to believe that the companies are already moving in this direction. The journal article suggests that the residuals are mainly due to inefficiencies in the manufacturing process. The reaction yield is 70%, meaning the 30% left behind from the monomer formation reaction will need to be removed from the product.

  • Why regulation is not a bad thing.

    Not always a fan of Monbiot, but this OP-ED piece on the government bailout of a British bank run by a libertarian intellectual contains in it, a passage that deserves to be framed.

    Wherever modern humans, living outside the narrow social mores of the clan, are allowed to pursue their genetic interests without constraint, they will hurt other people. They will grab other people’s resources, they will dump their waste in other people’s habitats, they will cheat, lie, steal and kill. And if they have power and weapons, no one will be able to stop them except those with more power and better weapons. Our genetic inheritance makes us smart enough to see that when the old society breaks down, we should appease those who are more powerful than ourselves and exploit those who are less powerful. The survival strategies that once ensured cooperation among equals now ensure subservience to those who have broken the social contract.

    Now, that is a cogent argument for regulation if I ever saw one.

  • John Kerry and the Environment

    The fight in the Senate | Gristmill: The environmental news blog | Grist

    Kerry, everyone’s favorite democrat summarizes the non-coal/auto democrat’s energy/environmental policy plans int he US senate.

    Highlights:

    1. Increase Fuel Economy standards
    2. Increase contribution of renewable sources
    3. No drilling in the Alaskan National Wildlife Refuge (ANWR)
    4. No liquid coal
    5. NO MORE COAL WITHOUT SEQUESTRATION!!!

    This is all very sensible. He does not mention biofuels/corn ethanol, which I guess is because he’s from Mass, not exactly corn central.

    He’s a good man, this John Kerry.

    Methane Leakage, again

    In a sane world, we would be very concerned about measuring, reporting and closely regulating methane releases during its extraction and processing, especially if we claim that it is clean energy. This is nothing I, or other people haven’t said before, but here’s more research summarized in the very respectable Nature Journal indicating that measurable leak rates of methane can vary widely.

    Preliminary results from a field study in the Uinta Basin of Utah suggesting even higher rates of methane leakage — an eye-popping 9% of the total production. That figure is nearly double the cumulative loss rates estimated from industry data — which are already higher in Utah than in Colorado

    via Methane leaks erode green credentials of natural gas : Nature News & Comment.

    10% is a large number. I’ve posted this picture from Wigley (2011) previously. At any leakage rate other than zero, which no one claims, the benefits of switching from coal to methane are very modest.

    It's all about Methane leakage
    It’s all about Methane leakage
    We absolutely need to measure, control and regulate fugitive methane emissions from every BC site, and need to have solid regulation in place before we keep expanding natural gas infrastructure. We need our political leaders to start talking seriously about capturing methane leaks when they talk about BC’s natural gas “play”.
