Models underestimate global warming impacts

No, not Tyra Banks and Riyo Mori, climate models that is.

ES&T Online News: Models underestimate global warming impacts

Modelers don’t purposely err on the conservative side, says Marika Holland of the National Center for Atmospheric Research, but some processes “are just not well understood, and because of that have not been incorporated into climate models.” Holland has published model results on the fate of sea ice and coauthored the recent paper showing that ice is melting faster than models predicted. There are many reasons for the underestimates, she says. For example, models don’t fully capture heat transport between ocean and atmosphere, or faster warming as reflective ice gives way to darker, heat-absorbing waters.
But Rahmstorf says that modelers might unwittingly make models more conservative by applying “one-sided filters”, weeding out models that clearly overestimate the changes seen so far, but hanging onto ones “where everything is too well behaved and stable.”

Scientists are human too. The political and social climate in the US have been harsh to people who overestimate the effects of climate change. So, modeling scenarios that deviate significantly from accepted limits or runaway uncontrollably are discarded. Models are sets of assumptions based on underlying theory. If the theory of a particular sub-process is not clearly understood, then the assumptions become subjective. In a social climate that is waiting to pounce on an overestimate as example of negating the entire global warming phenomenon, assumptions made are conservative. This is not necessarily a bad thing, but it comes at a price! As more observations come in, it does become clear that sometimes, things are happening faster and at greater magnitudes than our model predicted.

    What's the matter with Canada?

    But beneath the calm exterior, Canada’s political system is in turmoil. Since 2004, a succession of unstable minority governments has led to a constant campaign frenzy, brutalizing Canada’s once-broad political consensus and producing a series of policies at odds with the country’s socially liberal, fiscally conservative identity. Canada is quietly becoming a political basket case, and this latest election may make things even worse.

    What’s the matter with Canada? – By Christopher Flavelle – Slate Magazine

    I don’t necessarily agree with the whole “basket case” assertion, it is a fundamentally strong country with a broad consensus on what the country should be.

    The current set of political parties is rewarding a minority set of policies (the conservatives) by fragmenting the majority centre-left of centre consensus between 4 different political parties, none of which will talk to each other. This is not exactly new, the conservatives only merged their parties a few years back.

    The liberals suffer from Dion’s non Englishness, he gets little traction from the English media (no idea about the French, I don’t know any). He’s not that charismatic, nor does he orate well in English, and so like the American election, it is all optics. The liberals also seem to have no understanding of what it takes to win a modern election. The conservatives get in the news all the time, their ads are all over TV, the liberals seem to be MIA.

    Harper on the other hand is “strong”, strength of course being defined as sounding decisive and declaratory, even though he usually just sounds alarmist and hyperbolic all the time. Somehow, this is interpreted as leadership. I guess the only good quality of leadership is being loud.

    Dion also made a gamble by selling something called the Green Shift, a carbon tax, to increase efficiency in energy consumption and reduce greenhouse gas emissions. Even though the tax is designed to increase efficiency in a country notorious for its very poor efficiency (27th among the 29 OECD countries in energy use/capita), it is being demonized as a tax that will destroy the country (just like every other environmental regulation destroyed every other country). It is also bad timing, as energy prices have soared recently, and Canada’s economy sputters to a halt due to falling resource prices and the American housing market bust (destroyed the BC lumber industry). The last thing people want to hear is “tax”, even though the middle class will get more than sufficient rebates to cover any tax increases. The liberals seem to have overplayed this hand. Elections are never won on environmental issues, too easy to attack.

    The conservative pitch thus far has only been to attack Dion while offering some incremental changes. But as Harper is flirting with a majority, this Toronto Star editorial asks the right questions.

    While Harper is presenting himself as a kinder, gentler Conservative these days, in the past, as a Reform MP, head of the National Citizens’ Coalition and leader of the Canadian Alliance (successor party to Reform), he staked out quite radical positions. He has called Canada “a northern European welfare state in the worst sense of the term,” has denounced the “moral nihilism” of the Liberals and the left for opposing the Iraq war, has suggested building a “firewall” around Alberta, and has called for “market reforms” for health care, “further deregulation and privatization,” and “elimination of corporate subsidies.”

    With a Conservative majority in sight, it is fair for Canadians to ask Harper whether he still holds these views and would implement them once in office. And if the answer is No, Harper should use the remaining four weeks of this election campaign to tell voters just what he would do with a majority.

    The media lets Harper get away with sounding “presidential”, his proposals are very vague, and that is worrying. It is clear, however, that from an environmental standpoint, he will be a disaster. A combination of a slowing economy and reduced social support programs (conservatives hate safety nets for regular people) will be bad for the not so well off Canadians. We shall see what happens in a few weeks.

    An Ode to the Hummer? – Worst Column Ever

    GM desperately needs an obnoxious, attention-grabbing brand to keep from turning into a dreary shadow of its former self. And America needs the Hummer to remind us of what has always made our automobiles stand out, from the tailfin 1950s to the muscle car 1960s and ’70s: swagger. Americans don’t just drive their cars — they proclaim something about themselves by driving them.It takes a certain kind of man — it’s almost always the owner of a Y chromosome — to take a gander at the Hummer, in all its broad, burly, paramilitary gas-guzzling glory, and see himself behind the wheel, striking fear and loathing in the hearts of ecologically sensitive motorists

    Matthew DeBord – Hummer, How We Need Thee – washingtonpost.com

    Yes, and we men need to beat our women and keep them pregnant all the time to avoid turning us men into dreary shadows of our former self.

    Seriously, this is the Washington Post, the newspaper of record of the capital city of the great United States, and this is not a satire. Way to paint the entire American male population as masculinity obsessed rageholics whose only aim is to strike fear in the heart of others while dressed in military fatigues. This man must possess an unhealthy degree of self-hatred to conclude  that disdain of a poorly designed, horrendously inefficient vehicle is somehow hippie and communist.This man is a disgrace to all mankind.

    This, on the other hand is satire

    Ever since we changed our name from British Petroleum to BP (Beyond Petroleum) in 2000, we’ve led the way in developing progressive, environmentally friendly alternatives to gasoline. These last few years of pouring money into biofuels and renewable energy sources have been so great that I can’t for the life of me remember why we used to drill for dirty old oil in the first place! What’s that? You mean we’re still pumping that stuff from hundreds of refineries all over the world?

    Yes, when the Onion is better than the Washington Post, you know your country’s going to the dogs.

    Oak Bay goes electric

    Oak Bay has found the vehicles that fit its green policy and low speed limits — electric cars that top out at a maximum speed of 50 km/h.The municipality is drafting a bylaw that would allow electric cars on its public streets, making it possibly the first municipality in B.C. to take advantage of new provincial legislation that expands where the innovative vehicles can be driven.”I don’t think we’ll see any speed differences in Oak Bay just because we have slower-moving vehicles like electric cars,” Coun. Nils Jensen said yesterday of the impact on traffic movement in the notoriously slower-moving community.

    Oak Bay nears electric-car nirvana

     gv.gifFor those not in the know, Oak Bay is a municipality that is part of the Greater Victoria area. We have 11 separate municipalities, which makes for some serious inefficiencies and redundancy in administration, but does tend to preserve local character. Oak Bay, in my humble opinion, is insufferably British and proper, very wealthy and quite beautiful. And yes, it is a slow moving town, perfect for 50 kmph vehicles.

    But Oak Bay is not an island, it is flanked by Victoria and Saanich, and the boundaries are not always clearly demarcated. What’s going to happen when someone randomly wanders into Saanich?

    Except for the stretch of 17 going up to Sidney and the stretch of 1 going West and North out of the area, 50kmph ought to cover most of the area. I suspect Victoria will follow suit soon.

    newsobserver.com | Apex fire spreads toxic gas

    APEX – Fire crews have not begun to fight a fire at a hazardous waste plant that has spread a cloud of dangerous chlorine gas across Apex this morning, forcing more than 15,000 people to evacuate.Officials say they planned to send a hazardous materials crew in at daybreak to evaluate the fire. In the meantime, they’ve been letting it burn, out of concern that pouring water or foam on it would make things worse, said town manager Bruce Radford. The rain that started falling around 7 a.m. “doesn’t make anything better,” Radford said.

    The fire that followed a series of late-night explosions at Environmental Quality Co. just east of downtown has closed all Apex schools and school bus routes that start inside the Western Wake town. In addition, the Wake County Public School System said bus transportation elsewhere in Western and Southwestern Wake County would likely be delayed this morning. Green Hope High School in Cary, which is being used a shelter for evacuated residents, will also be closed.

    Officials urged people to evacuate an area bounded by U.S. 1, N.C. 55 and U.S. 64 highways in Apex and unincorporated areas. Police are blocking roads into the center of town, and Radford urged everyone to stay away.
