Climate Change – Killing Trees in Our Neighbourhood

Well, anyone who says that temperate countries could do with a little warming ought to read this study. Trees are dying at double the usual rate in the last 17 years.

Warmer temperatures have dramatically increased the rate at which trees in old-growth forests are dying in parts of British Columbia and the western United States, a study says.

The study, to be published in Friday's edition of the journal Science, found that mortality rates for trees in the old-growth plots in the Pacific Northwest — including parts of southern British Columbia — had doubled in 17 years.

Forests in California and other states had less dramatic numbers. The interior states — like Arizona, Colorado and Idaho — had tree mortality rates that doubled every 29 years. The mortality rates change incrementally every year, the researchers say.

“We may only be talking about an annual tree mortality rate changing from 1 per cent a year to 2 per cent a year, an extra tree here and there,” study author Mark Harmon, professor of forest ecology at Oregon State University, said in a statement.

“But over time a lot of small numbers can add up. The ultimate implications for our forests and environment are huge.”

The increases in mortality rates are replicated across all trees at every elevation, regardless of species or size.

The study, which the researchers say is the first of its kind on temperate forests, gathered data on 76 long-term forest plots over a 50-year period for analysis. All of the forest areas studied were at least 200 years old, although individual trees varied in age and size.

The study controlled for all other variables including the infamous pine beetle, and found that temperature increase was to blame. Why? A 1ºC rise in temperature results in less snow, longer summer and increased drought stress. The effects on any one individual tree would not be significant, but if you look at an entire population, these stresses caused a doubling of mortality.

    Corn Can’t Solve Our Problem – washingtonpost.com

    If every one of the 70 million acres on which corn was grown in 2006 was used for ethanol, the amount produced would displace only 12 percent of the U.S. gasoline market. Moreover, the “new” (non-fossil) energy gained would be very small — just 2.4 percent of the market. Car tune-ups and proper tire air pressure would save more energy.

    Proper tire pressure is not sexy, and does not lead to billions of dollars of profits!

    The net effect is that ethanol from corn grown in the Corn Belt does increase atmospheric greenhouse gases, and this increase is only about 15 percent less than the increase caused by an equivalent amount of gasoline

    Corn is such a boondongle, it’s amazing what the ADMs and Monsantos of the world can do.

    This means that when tropical woodland is cleared to produce sugar cane for ethanol, the greenhouse gas released is about 50 percent greater than what occurs from the production and use of the same amount of gasoline. And that statistic holds for at least two decades.

    Brazil will not solve all your problems (unless they’re samba related!). Increased demand for ethanol from Brazil could lead to clearcutting of the rain forest/other fallow grassland.

    Across the full process of growing high-diversity prairie hay, converting it into an energy source and using that energy, we found a net removal and storage of about a ton and a half of atmospheric carbon dioxide per acre. The net effect is that ethanol or synthetic gasoline produced from this grass on degraded land can provide energy that actually reduces atmospheric levels of carbon dioxide.

    It’s a very well written article.

  • Canada and Climate Change Regulation – Politics as Usual

    Weasel (from wikipedia)

    *Weasel picture courtesy wikipedia

    “We need to hear more about the American position, the European position, the Chinese position” before considering the bill, McGuinty told CBC News.

    CBC

    With that rather weasely statement, Canada’s Liberal Party signalled that it will support a further delay in a vote that would set realistic limits on Canada’s Greenhouse gas emissions. I was too angry yesterday to write a decent post about it, but hey, as my partner often says, “Anger is a positive emotion”. So, here goes.

    What is it?
    Bill C-311 – The Climate Change Accountability Act. aims to set binding emission targets for greenhouse gas emissions (excluding land use, land use change and forestry) for Canada. Here’s the a short sentence from the preamble:

    this legislation is intended to ensure that Canada reduces greenhouse gas emissions to an extent similar to that required by all industrialized countries in order to prevent dangerous climate change, in accordance with the scientific evidence on the impacts of increased levels of global average surface temperature and the corresponding levels of atmospheric concentrations of greenhouse gases;

    Okay, ending a long sentence with a semi-colon, strange, but there it is, a very clear and concise statement of fact intending for Canada to set realistic targets for GHG reduction

    What are the targets?
    25% below 1990 levels by 2020, 80% below 1990 levels by 2050. This is in line with IPCC recommendations (pdf) (See page 776, thanks Climate Progress) to stabilize temperature rise to < 2°C and GHG concentrations to 450 ppm CO2 eq.
    Hansen, other prominent scientists and activists at 350.org have a more ambitious target in mind, 350 ppm. In comparison, proposed legislation by John Kerry and Barbara Boxer in the US senate would reduce GHG emissions by 20% from 1990 levels, and 80% by 2050. So, this bill proposes targets that are in line with what the world’s greatest polluter (per capita, historical) is proposing and current official consensus. There is a lot of small print in the exemptions, agriculture is a big one on the US side and land use and forestry appear to be a rather significant omission on the Canadian side.

    Bottom Line: The targets are exactly what is recommended by the IPCC, are reasonable and in line with what our biggest trading partner has proposed. They need to be strengthened in the near future, but are good for now.

    What it doesn’t do
    It does not establish a mechanism to bring about these reductions, only specifies that the government come up with scientifically sound interim targets and an emissions reduction regulatory strategy, be it emissions trading, or carbon taxes, etc. That’s fine, given Canada’s balance of powers and separation of province-federal powers, it would be best for an executive approach to regulation writing.

    History

    Bill C-311 is not new. An identical version passed the House of Commons in 2008 and was stymied by an election call. Since Canada has a bicameral legislature, the bill needed to be passed by the Canadian Senate as well and the election blocked this vote. Right now, it needs a vote to get out of committee and on the floor of the House.

    So what happened?
    Well, the NDP wanted to get the bill out for vote. The Bloc Quebecois supported them. The Conservatives, in a delaying tactic, wanted to extend the committee study period for another month, citing a “need for more expert testimony”, the Liberals agreed with them and the bill is stalled for now. Why? It is all politics.

    The Politics
    This is where the story gets interesting, and epitomizes everything that is wrong with Canada’s current political system! Canada is currently (since 2006 and 2 elections on), run by a minority Conservative government. Minority governments work very differently in Canada compared with typical parliamentary democracies such as India, Israel, etc. There are no coalitions, no alliances, especially now since the Conservative party is well to the right of every other party in Parliament. Canada has four other prominent parties, the Liberals, a centrist, business friendly party that has previously governed, the NDP, a left leaning union friendly party, the Green party, an environmental issues and good governance driven party (no seats in parliament), and the Bloc Quebecois, a regional party based in Quebec which wins seats only in Quebec.

    For the Conservative party to pass legislation, they need the support of one other party. Of course, to stymie legislation, they can use various parliamentary procedures. This is why C-311 is a private member’s bill, the government, which is vehemently opposed to any meaningful climate change mitigation regulation, would not bring something like this up for vote.

    The NDP would like to be responsible for meaningful regulation on climate change as it is in line with their stated principles and also neatly aligns with their desire to be seen as a serious opposition party, and as a party capable of governing at the federal level.

    The Liberals, well, they ran their last election on a radical restructuring of the Canadian tax system called the Green Shift. This envisaged a reduction in personal income taxes combined with the establishment of a carbon tax. The Liberals lost the election, and have been a lot more cautious about bringing up environmental issues. I happen to believe that the loss was primarily due to poor election strategy, a leader with the charisma of a freshly painted wall, and a flawed electoral system that allows for too much vote splitting, “wasted” votes and is unrepresentative. But, the media has run with the “it must be the environment” meme, and currently view any environmental legislation as a vote loser. This is in direct contradiction with polling data (pdf) that indicates the opposite to be true.

    Anyway, the Liberals appeared to be getting back into the energy game. Their dear leader Michael Ignatieff (@m_ignatieff) recently tweeted about a revolutionary new clean energy plan, which seems sensible enough and forward thinking. Also, the Liberals supported this identical bill last year, and until recently. Here’s the NDP with a collection of helpful quotes from the Liberals on C-311:

    “Parliamentarians don’t know where this country is going, as a sovereign nation state, on climate change. The really good news and the good faith behind Bill C-311 is helping to prompt a timely debate of where we’re going in advance of the important Copenhagen negotiation.” – David McGuinty, Environment Committee, June 18, 2009

    “[Bill C-311] has been reintroduced under a new MP, a bill that was put forward in the last Parliament by the leader of the NDP. As such, it really has no material changes compared to its predecessor bill.” –David McGuinty, Hansard, March 4, 2009

    “It’s very simple: we won’t be taken seriously until we are serious about the environment.” – Speech to the Vancouver Board of Trade, October 13, 2009 – MIchael Ignatieff

    Unfortunately, the price for success against the government in this half-assed minority government situation is likely an election! Opinion polls indicate that an election held today would likely result in very much the same situation as the last time around, maybe even an increased near majority for the Conservatives.

    The Conservatives (in blue) have a solid lead over the Liberals (Red) and the NDP (in orange) apparently have a 20% ceiling. In a normal parliamentary system, this would mean an alliance between the NDP and Liberals to win the election pretty handily (note that the votes would not additive, but there is a conservative vote ceiling around 40%). But as long as electoral reform is off the table, and the extremely hidebound Canadian mainstream media does nothing other than bemoan the lack of electoral participation while roundly condemning any alternative that would increase such participation, we are stuck with ths situation in which a Conservative government takes this country slowly rightward where it really does not want to be taken, given that solid majorities are against said conservative policies.

    In Conclusion
    Canada dithers again on climate change. To the core supporters of the Conservative party, this is as should be. However, for the majority of the country, for the international reputation of the country, and for the political system as a whole, this is an unacceptable delay. The Liberals win no friends by being indecisive and showing no leadership. The NDP is stuck with no amount of “responsible” opposition work giving it any traction in the polls, the political intelligentsia of Canada would not accept an NDP ascendancy. The political system does not reward cooperation. So, we remain stuck, a country of many beautiful words and very little action.

    Happy Friday!

    A Company that Specializes in Profiting from Harm

    The LA Times has an interesting investigation on the activities of Amvac.

    Pesticide maker sees profit when others see risks – Los Angeles Times

    Amvac is a leading maker of organophosphates, a class of older, highly toxic pesticides that has been under regulatory scrutiny since the late 1980s. As larger firms have stopped manufacturing some of their organophosphates, Amvac has bought the rights to make or sell 10 of them since 1989, according to company records and interviews. One of them, mevinphos, was banned in the U.S. in 1994 after a study by the U.S. Environmental Protection Agency found that it was responsible for poisoning more field workers in California than any other agricultural chemical. Amvac continues selling the product overseas, according to company officials. Amvac is by no means the largest producer of pesticides that have attracted regulatory scrutiny, but the company stands out for its willingness to embrace chemicals that other firms have abandoned.

    Amvac Slogan

    Love that slogan, don’t ya’! There are so many loopholes in pesticide regulation that a company like Amvac can post impressive profits by using these loopholes, having a significant say in the writing of the regulation, and effortlessly denying and delaying action. It’s a well researched piece, read in full.

  • The Costly Compromises of Oil From Sand

    The New York Times prints a summary of the issues facing Canada’s Oil Sands. Of course, most people are well aware of the huge environmental impacts, water pollution, strip mining, destruction of avian habitats, greenhouse gas emissions, air pollution, you name it, they got it. The NY Times waits till the penultimate paragraph to get to the most important point:

    Even if Canadian producers dislike American climate change policies, they will be hard-pressed to sell their oil elsewhere. Canada’s pipeline network takes oil sands production south and offers no routes to ports for export to other countries.

    The Costly Compromises of Oil From Sand – NYTimes.com

    In essence, any meaningful climate change regulation in the United States directly affects the viability of these projects. Canada is already trying to lobby against existing US regulation that explicitly forbids the use of fuels with higher lifecycle carbon emissions that conventional fuels by the military.

    Nothing new in the article, just a reminder that any noises you hear emanating from Canada about US climate change regulation are driven by this issue.

  • E.P.A. to Regulate greenhouse gases

    The Environmental Protection Agency has moved to declare that greenhouse gases are pollutants that pose a danger to the public’s health and welfare. That determination, once made final, will pave the way for federal regulation of carbon dioxide, methane and other heat-trapping gases linked to global warming.

    via NY Times

    Of course, this action was required by a US Supreme Court decision on greenhouse gases last year and provides the regulatory side to the push that must come from congress.

    There have been recent rumblings that the US Congress would shelve climate change for 2010. While this would please some Americans in the short term, the idea of the US going into the Copenhagen climate change conference without a GHG reduction plan out on the table leaves me very dispirited. The timing of the EPA’s announcement suggests that there might be some pressure from the EPA to get Congress to act. It is clear that the EPA does not have breadth of scope to pull of climate change regulation using a rule making process. Maybe if it starts trying, American politicians may get their act together.

    Clutching at straws…
