Carbon Trends 2007

Emissions increased from 6.2 PgC per year in 1990 to 8.5 PgC in 2007, a 38% increase from the Kyoto reference year 1990. The growth rate of emissions was 3.5% per year for the period of 2000-2007, an almost four fold increase from 0.9% per year in 1990-1999. The actual emissions growth rate for 2000-2007 exceeded the highest forecast growth rates for the decade 2000-2010 in the emissions scenarios of the Intergovermental Panel on Climate Change, Special Report on Emissions Scenarios IPCC-SRES. This makes current trends in emissions higher than the worst case IPCC-SRES scenario. Fossil fuel and cement emissions released approximately 348 PgC to the atmosphere from 1850 to 2007.

Carbon Trends 2007.

This is very scary news, and there’s more in the carbon budget for the last 7 years released here. It shows a total lack of leadership from the US, Canada, and Europe, countries responsible for over 80% of the historical anthropogenic contribution.

    But Mr. Peterson, when asked by reporters Tuesday about the report’s findings, said they run counter to what many in his region are experiencing

    “We’ve just had the biggest floods and coldest winters we’ve ever had,” he said. “They’re saying to us [that climate change is] going to be a big problem because it’s going to be warmer than it usually is; my farmers are going to say that’s a good thing since they’ll be able to grow more corn.”

    So, it appears that every party in power South of the Border needs an influential legislator making ridiculous statements deliberately confusing weather and climate to derail even the weak sauce that is passing through the US congress right now.

    Millions of people are in the process of becoming climate refugees while this “Corn”gressman and his big agriculture cronies dither, lie and weaken climate change action.

    At what point in time does deliberate obstruction of action that will save lives and homes become sabotage and assault?

  • Carbon tax Front and Centre in the Canadian Campaign

    The battle for Quebec in the federal election campaign heated up on Thursday with Conservative Leader Stephen Harper telling a Montreal audience that Liberal Leader Stéphane Dion's carbon tax proposal threatens Canada's national unity.

    "The carbon tax will do more than undermine the economy," Harper said to a crowd of business leaders. "By undermining the economy and by re-centralizing money and power in Ottawa, it can only undermine the progress we have been making on national unity."

    CBC.ca – Canada Votes – Dion’s Green Shift threatens national unity: Harper.
    Mr. Harper is calling for disaster if there’s any kind of serious carbon dioxide mitigation plan. His party’s plan, as I mentioned a few days back, is pretty toothless, and his attitude does not bode well for climate change mitigation policy in Canada.

    Flame Retardants and Hyperthyroidism in Cats

    Caveat Emptor: They found a correlation, not a causative mechanism. But Polybrominated Diphenyl Ethers (PBDEs, yum!) have structures that can mimic endocrine hormones. Because hormones signal at very low doses and continuously, our whole toxicological risk testing structure of looking for acute effects at high doses and trying to extrapolate those effects to low doses is flawed for endocrine disrupting compounds. We are finally beginning to see some new research, especially with other toxics such as Bisphenol A, which test for chronic conditions and subtle gene and hormonal signalling effects at low doses. After all, small changes in hormone regulation especially at childbirth and a young age can have very serious effects later on in life.

    Inside Bay Area – NEW: Flame retardants linked to thyroid disease in cats

    A mysterious epidemic of thyroid disease in cats may be linked to flame retardants common in carpets, foam furniture and mattresses, according to U.S. Environmental Protection Agency researchers, who suggest that scientists have underestimated the damaging health risk the chemicals pose to humans.

    The research, published Wednesday in the journal Environmental Science and Technology, does not prove these compounds, known as PBDEs, caused the rash of hyperthyroidism in the nation’s household cats over the past 30 years.

    Rather, it lays out a hypothesis, showing that cats are heavily contaminated by these compounds, which leach from household products and are found everywhere, particularly household dust. Cats, meticulous cleaners, ingest PBDE-contaminated dust daily.

    The case of fire retardants is especially difficult because they save many lives, so manufacturers can always point to that fact and resist change. The logical fallacy, however is as follows:

    1. Fire retardants save lives (therefore good)
    2. PBDEs are fire retardants
    3. Therefore, PBDEs are good!!

    The search for a safer fire retardant needs to continue, and will not happen unless the old ones are under pressure of being phased out.

  • Volcanos and Climate Geoengineering

    The first thing that occurred to me when I heard about the Sarychev eruption was whether it was going to be large enough to inject significant quantities of sulphate aerosol into the stratosphere. Apparently, it is.

    Sarychev Eruption Generates Large Cloud of Sulfur Dioxide

    When sulfur dioxide reacts with water vapor, it creates sulfate ions (the precursors to sulfuric acid), which are very reflective. Powerful volcanic eruptions can inject sulfate aerosols into the stratosphere, beyond the reach of cleansing rainfall. At these altitudes, the sulfates can linger for months or years, cooling the climate by reflecting incoming sunlight. (The effect is stronger when the eruptions occur at tropical latitudes.) Carn says the persistence of such high concentrations of sulfur dioxide in the OMI data throughout the week indicates that the plume from Sarychev Peak reached high altitudes. Data from other satellites (such as CALIPSO) suggest that the volcanic plume reached altitudes of 10–15 kilometers, and perhaps as high as 21 kilometers.

    In 1991, the eruption of Mount Pinatubo in the Philippines injected enough sulphate into the atmosphere to cause a 0.5° C drop in global temperature. This was caused by about 20 million tonnes of SO2. We are nowhere close to these kind of emission levels. After all, Pinatubo was one of the two biggest volcanic events of the century.

    Injecting sulphate particles into the stratosphere has been proposed for a while now, I first wrote about it in 2006 when a prominent atmospheric chemist, Paul Crutzen wrote an article proposing this. The science behind this proposal is basic, sulphate aerosols of the size that would be formed from the oxidation of SO2 are the right size to scatter and reflect solar radiation back into space (my Masters thesis did a first order estimate of this effect from Indian emissions!). If injected directly into the stratosphere, they can stay there for a long time and will not deposit to the the Earth’s surface as acid rain. The issue is managing all the crazy regional variations in climate that would result, and the attendant complications in assigning blame, etc. It would also not help the oceans, which would acidify to hell with all the CO2.

    Anyway, so much for that, the volcano is causing all kinds of havoc with Pacific travel and making for all kinds of cool pictures, which are about the most interesting thing happening at this point in time. We shall see how the sulphate situation plays out in the days to come when the dust settles.

    Canada to stop asbestos mining and stop defending it.

    Canada’s long and sorry saga of exporting death (asbestos) and defending it loudly and proudly in international fora is over and I needed to mark this happy day on the blog. The newly elected provincial government in Quebec, the Parti Quebecois have followed through on their campaign promise to finally end this small “industry” employing a few workers. Canada will no longer produce asbestos, or fight the listing of asbestos as a toxic substance.

    It is going to take $50 million in government funds, a fraction of the cost of one fighter jet, to transition the workers away (if they get the money, not the mine owners). That’s it, why were we exporting death to India and other countries for this, I don’t know.

    Canada’s many conservative and liberal governments fought hard for years to preserve the industry, using techniques lifted from tobacco propaganda, or today’s climate change challenges. I leave you with the ruling Canadian government’s response: Finely tuned to appeal to everyone who likes mesothelioma, cancer and death.

    “Mrs. Marois’s decision to prohibit chrysotile mining in Quebec will have a negative impact on the future prosperity of the area,” (Industry Minister) Mr. Paradis said in a statement.

    That about sums it up. But, it is a good day for public health, nevertheless.

  • More Focus on China – Pesticides and Food Safety

    I begin to wonder how much of this was not known previously, and is coming out now, pushed by US domestic food interests who can suddenly become a little more competitive.

    Reuters AlertNet – Pesticides next frontier in China food safety

    China’s farmers overuse pesticides, skip protective clothing and have at their fingertips an array of banned and counterfeit products, raising another area of concern in the country’s fragile food chain. Spraying chemicals on crops improperly or using products that may be fake or banned risks the health of China’s hundreds of millions of farmers and could lead to unsafe levels of residues in fruits and vegetables, experts say. “The government has to stop banned or illegal pesticides being available in the market,” said Angus Lam, a Greenpeace Campaign Manager for Food and Agriculture based in the southern city of Guangzhou. China banned five high toxicity pesticides as of Jan. 1, but Lam said old stock was still in the market, in the hands of traders, retailers and farmers themselves. The government pledged last week to step up inspections in its food industry, saying checks on fertilisers and pesticides would be one of the priority areas.

    China is not alone in this problem. Pesticides get overused in the US as well. But it’s as if all of a sudden, the mainstream press is waking up to the reality that is China. It is a developing country with high levels of growth in manufacturing, and a burgeoning middle class. But government regulation mechanisms have a long way to go to catch up.

    The US surely knows this, and needed to have a more stringent testing regime with food imports from China. But the FDA was not given the mandate or the money. It is very easy to blame the FDA here. The fact of the matter is that any agency is only as good as the money and mandate it’s given. The political will to take a good look at where your food comes from, and how to ensure its safety needs to come first.
