ScienceDaily: Scientists Warn Of Climate Change Risk To Marine Turtles

North American marine turtles are at risk if global warming occurs at predicted levels, according to scientists from the University of Exeter. An increase in temperatures of just one degree Celsius could completely eliminate the birth of male turtles from some beaches. A rise of three degrees Celsius would lead to extreme levels of infant mortality and declines in nesting beaches across the USA.

Here’s the paper.

Like a lot of other reptiles, the sex of the hatchling is dependent on nest temperature. Warmer temperatures make female turtles (my mnemonic was hot females!), and even warmer temperatures just kill the eggs. But, I wonder if the turtles would adapt by nesting a little earlier. I don’t think it is yet clear when turtles decide to nest. If it is based on sea temperature, then they would eventually figure it out. This paper from 2004 appears to conclude that loggerheads in Florida do nest earlier than before, so there is hope.

John F. Weishampel, Dean A. Bagley, Llewellyn M. Ehrhart (2004) Earlier nesting by loggerhead sea turtles following sea surface warming Global Change Biology 10 (8), 1424–1427

The onset of spring, noted by the timing of wildlife migratory and breeding behaviors, has been occurring earlier over the past few decades. Here, we examine 15 years of loggerhead sea turtle, Caretta caretta, nesting patterns along a 40.5 km beach on Florida’s Atlantic coast. This small section of beach is considered to be the most important nesting area for this threatened species in the western hemisphere. From 1989 to 2003, the annual number of nests fluctuated between 13 000 and 25 000 without a conspicuous trend; however, based on a regression analysis, the median nesting date became earlier by roughly 10 days. The Julian day of median nesting was significantly correlated with near-shore, May sea surface temperatures that warmed an average of 0.8°C over this period. This marine example from warm temperate/subtropical waters represents another response of nature to recent climate trends.

So the truth lies somewhere between easy adaptation and giant swarms of frustrated female turtles!

    Bush Recess Appointment Threatens Public Protections – Press Room – OMB Watch

    2007—President George W. Bush today installed Susan Dudley as White House regulatory czar through a recess appointment. Dudley will now serve in the White House Office of Management and Budget as administrator of the Office of Information and Regulatory Affairs (OIRA).

    OIRA is a powerful office responsible for reviewing and approving federal agencies’ most significant regulations. Installing Dudley threatens decades of public health and safety protections; doing so by recess appointment endangers our democratic process.

    “Dudley’s record is one of anti-regulatory extremism,” said Rick Melberth, Director of Regulatory Policy at OMB Watch. “She has opposed some of our nation’s most basic environmental, workplace safety and public health protections.”

    Dudley has falsely proclaimed ground-level ozone to be beneficial, opposed ergonomic standards to protect workers from repetitive stress disorders, and even suggested that airbags should never have been mandated in automobiles.

    The kinds of rollbacks Dudley may push forward could render useless valuable federal laws that have saved countless American lives. OMB Watch and Public Citizen documented Dudley’s anti-regulatory views in a September 2006 report, The Cost Is Too High: How Susan Dudley Threatens Public Protections.

    Dudley’s strong ties with the industries she will be regulating pose an obvious conflict of interest. For the three years before her nomination, Dudley directed the Regulatory Studies program at the Mercatus Center — an industry-funded, anti-regulatory think tank. It is likely that industry executives will have unprecedented access to Dudley, while concerned citizens will be increasingly shut out.

  • Nepotism, Environmental Edition – High alert

    Byoliveridley

    In the fast emerging banana republic that is the US of A, apparently, and this was news to me, the vice president’s son-in-law wields a lot of power! I am laughing very hard at the cronyism while I remain concerned about the effects. But, remember Americans, democracy begins at home! While you’re busy lecturing, and invading other countries to “spread democracy”, your vice president’s family acts as if their “descended from god” line to the throne gives them divine right to rule by fiat.

    Dick Cheney’s Dangerous Son-In-Law – Art Levine

    To understand the workings of Philip Perry is to get a sense of the true lines of power in the executive branch. “Perry is an éminence grise,” says one congressional staffer. “He’s been pretty good at getting his fingerprints off of anything, but everyone in this field knows he’s the one directing it. He is very good at the stealth move.” And, as it turns out, Perry’s stealth moves have often benefited opponents of chemical regulation. One of his final pieces of handiwork included coming up with what critics have called an “industry wish list” on chemical security that ultimately became law last fall. “Every time the industry has gotten in trouble,” says the staffer, “they’ve gone running to Phil Perry.” The result has been that our chemical sites remain, even five years after 9/11, stubbornly vulnerable to attack. Philip Perry has hardly been alone in tolerating this. Others in the White House and Congress have been equally solicitous toward the chemical industry. But as part of a network of Cheney loyalists in the executive branch, Perry has been a key player in the struggle to prevent the federal government from assuming any serious regulatory role in business, no matter what the cost. And a successful attack on a chemical facility could make such a cost high indeed. A flippant critic might say the father-in-law has been prosecuting a war that creates more terrorists abroad, while the son-in-law has been working to ensure they’ll have easy targets at home. But it’s more precise to say that White House officials really, really don’t want to alienate the chemical industry, and Perry has been really, really willing to help them not do it.

    Nice work. The alternative that the EPA wants to pursue is called inherently safer technologies, or IST. Read the whole article to follow all the behind the scene machinations. Next time a pesticide plant blows up in N.J releasing tons of chlorine, you can bet that none of the people involved in these maneuvers will be anywhere near the fallout!

    Chinese coal mines in BC: Missing the forest for the trees

    Byoliveridley

    The story of a Chinese company in BC hiring Chinese workers has received a lot of attention. Much of the attention has focused on the company’s decision to game the temporary worker system in order to avoid hiring “Canadian” workers. Many of the objections are made on nationalistic grounds, “OMG, THEY”RE TAKING CANADIAN JOBS”, which then leads down the path of racist anti-Chinese sentiment. This Tyee article (disclaimer: I am a Tyee monthly funder, but obviously have no editorial input!) summarizes the issues involved very well. Recent changes to Canada’s immigration laws make this kind of hiring logical, because it is now okay to pay temporary workers with little/no bargaining power 15% less than you would pay locals. Of course you have to document that there were no qualified locals, but as this particular incident indicates, there’s little/no actual enforcement unless a fuss is made.

    I find temporary worker programs to be problematic because they provide no path to citizenship, no permanence for the people who want it, and cause ugly divisions in the community. If you think there are not enough “workers” in your community, open your borders, let them in and pay well, you’d be surprised.

    I wanted to highlight two obvious issues that to my mind are as important:

    1. Carbon Bomb. It’s a coal mine! How many people in BC, which preens gloriously on its carbon tax, are aware that coal is BC’s Number One export? What is the point of having a carbon tax for consumers when producers get to make money off that carbon for free? Whether the coal is burned in BC, or in China, it causes the same damage. Whether the coal is used to generate power, or to make steel, it puts out the same amount of carbon dioxide. Whether the mine uses Chinese workers or locals, it produces the same climate changing emissions. So, why instead of making coal producers pay the real costs of their product, are we enabling them to evade carbon taxes, royalties, and save even more money by reducing wages? Also, coal mining is not employment intensive, as countless other people have pointed out. So it’s not really about the jobs either. Kevin Washbrook of StopCoal made this point as well in the Tyee article I linked to earlier.
    2. Does this mine have right to be there? The West Moberley First Nation, part of a Treaty 8 band is opposed to the project on its land. That should be the end of the story. The state of Canada has responsibilities as a settler entity to obtain free, prior and informed consent on development from the people it colonized. The US is a bit more honest in this regard as it regards the colonization as a thing of the past and gives its indigenous peoples little/no rights. Canada’s different, the indigenous here have specific standing because of Canada’s existing colonial links and Canadian governments and courts routinely confirm this standing. The BC government is currently negotiating treaties with many First Nations communities including the West Moberley First Nation.

    We’re trying to set up a climate and environment disturbing, cost and tax evading coal mine on land that belongs to someone else using easily exploited temporary workers we can be racist towards.

  • Coal-to-Liquid: Useless

    Byoliveridley

    Liquid transportation fuels derived from coal and natural gas could help the United States reduce its dependence on petroleum. The fuels could be produced domestically or imported from fossil fuel-rich countries. The goal of this paper is to determine the life-cycle GHG emissions of coal- and natural gas-based Fischer−Tropsch (FT) liquids, as well as to compare production costs. The results show that the use of coal- or natural gas-based FT liquids will likely lead to significant increases in greenhouse gas (GHG) emissions compared to petroleum-based fuels. In a best-case scenario, coal- or natural gas-based FT-liquids have emissions only comparable to petroleum-based fuels. In addition, the economic advantages of gas-to-liquid (GTL) fuels are not obvious: there is a narrow range of petroleum and natural gas prices at which GTL fuels would be competitive with petroleum-based fuels. CTL fuels are generally cheaper than petroleum-based fuels. However, recent reports suggest there is uncertainty about the availability of economically viable coal resources in the United States. If the U.S. has a goal of increasing its energy security, and at the same time significantly reducing its GHG emissions, neither CTL nor GTL consumption seem a reasonable path to follow.

    Comparative Analysis of the Production Costs and Life-Cycle GHG Emissions of FT Liquid Fuels from Coal and Natural Gas.

    To summarize, no cost benefits, increased GHG emissions, a lot of uncertainty, let’s not follow this madness of trying to make coal into gasoline.

    Bhutan to pay for others climate sins

    Byoliveridley

    Bhutan is a small country nestled in the Himalayas, breathtakingly beautiful and “quaint”. Unfortunately, it’s about to be hit by a truck!

    Reuters AlertNet – FEATURE-Bhutan to pay for others climate sins

    The retreat of Bhutan’s glaciers presents an even more formidable and fundamental challenge to a nation of around 600,000 people, nearly 80 percent of whom live by farming.

    Bhutan’s rivers sustain not only the country’s farmers, but also the country’s main industry and export earner — hydro-electric power, mostly sold to neighbouring India.

    For a few years, Bhutan’s farmers and its hydro power plants might have more summer melt water than they can use. One day, though, the glaciers may be gone, and the “white gold” upon which the economy depends may dry up.

    The threat led the government’s National Environment Commission to a stark conclusion.

    “Not only human lives and livelihoods are at risk, but the very backbone of the nation’s economy is at the mercy of climate change hazards,” it wrote in a recent report.

    Scientists admit they have little solid data on how Bhutan’s climate is already changing, but say weather patterns are becoming increasingly unpredictable.

    Well, as I keep saying, Americans and Europeans will be incovenienced by global climate change, Asians and Africans will die. I don’t have an answer, though, which is depressing on this gray and cloudy Friday morning…
