Anything related to Canada or Canadians
So, what do people expect from the ongoing British election? A Tory minority? Some sort of coalition between the Liberal Democrats and another party?
In the longer term, what might the consequences be? In particular, will some sort of proportional representation be implemented in the UK? If so, might Canada ever follow suit?
Over the weekend, I found myself wondering about the relative impact of Canada’s extremely controversial seal hunt and climate change, when it comes to the prospects for Grey Seals and Harp Seals.
Given that it seems highly likely that climate change will eventually eliminate summer sea ice, and given that creatures including seals seem to be critically dependent on sea ice, it does seem possible that climate change will render these seal species extinct, eventually, or will sharply curtail their numbers.
Stage one of a comparative analysis would be developing an estimate of how many seals would have lived between the present and the non-human-induced extinction of the species. They could potentially endure until the end of the carbon cycle, or until the sun expands into a red giant. More plausibly, they might exist in large numbers until the next time natural climate change produces a world too hot to include Arctic sea ice.
If we had an estimate of how far off that probably is, and an estimate of the mean number of seals that would be alive across that span, then we can estimate how many seals would be lost if humanity eliminates summer sea ice and, by extension, wipes out or sharply curtails the number of these animals in the wild.
It is possible to imagine a chart showing seal population year by year, extending far into the future. There could be one shaded segment showing the projected seal population in the absence of human intervention, and others showing possible population crashes resulting from anthropogenic climate change. A third shaded area could show the number of seals taken annually by hunters. The relative area of the shaded regions would show the relative magnitude of hunting and climate change, as causes of seal mortality. If you think of all the seals that would have lived, if we hadn’t locked in the eventual disappearance of summer arctic sea ice, the number killed by hunters is probably quite small.
My suspicion is that hunting would be a tiny blip, compared with climate change. If so, the environmentalist campaign to end seal hunting seems misdirected. Even if protesters are more concerned about animal cruelty than about species sustainability, this argument seems to hold up. Surely it is cruel for the seals to suffer and slowly die off as their habitat loses the capacity to sustain them.
I think it would be well worth some serious organization producing an quantitative version of the argument above. Like ducks, it seems quite possible that seals are distracting us from the environmental issues we should really combating, or at least encouraging us to respond to those issues in a less effective way than we could.
In another demonstration of how many conservatives are hypocrites when it comes to the environment, we have the sorry example of Canada’s billion dollar green energy fund.
Contrast these two situations:
The former approach demonstrates faith in innovation and market mechanisms. The latter approach suggests that the indefinite combination of government analysis and lobbying can somehow do better.
If we want to address climate change in a fair and effective way, we should be making firms and individuals pay the true costs of what their actions impose on everyone, while banning the most destructive activities. We should not be setting up weird mechanisms for political patronage.
This Wednesday, Bill C-311 (Climate Change Accountability Act) will be debated at Report Stage. This NDP-sponsored bill includes targets of a 25% reduction in emissions below 1990 levels by 2020, and 80% below by 2050. It also obliges the government to produce an emissions target plan for 2015, 2020, 2025, 2030, 2035, 2040 and 2045.
I don’t know that the bill’s prospects for passing are, but it seems likely to have little effect in any case. Parliament previously passed the Kyoto Protocol Implementation Act, in the face of government opposition. The government refused to alter its climate change mitigation plans in response, and the Supreme Court Federal Court of Appeal ruled that the law was ‘not justiciable’ and therefore not for the courts to enforce.
The only importance this bill seems likely to have is a mild and symbolic one. If it passes, it will show continued dissatisfaction on the part of opposition parties about the government’s climate plan. If it fails, it risks showing the opposition parties divided on the issue, or unwilling to make it a priority.
[Update: 13 April 2010] This post originally made reference to the Supreme Court of Canada, whereas it should have made reference to the Federal Court.
[Update: 15 April 2010] The bill passed the Report Stage and will go to Third Reading, probably via committee. The motion to send it to Third Reading passed by 155 to 137.
The Ontario government has just announced $8-billion in renewable energy projects, to be undertaken by dozens of companies with the aim of increasing renewable capacity by 2,500 megawatts.
Investing in the energy systems of the future just makes sense. Ontario could improve on this further by accelerating their planned coal phase-out from 2014 to this year.
The Economist recently published an article lamenting how little funding is devoted to tracking the quantity of greenhouse gases in the atmosphere. States do produce bottom-up records of emissions, based on what various facilities and vehicles emit. But it is also possible to track the accumulation of heat-trapping gases in the atmosphere directly, and to infer things about emissions from regional variations in concentrations and from isotopic ratios which can help to identify the sources of gases like CO2 and methane. As explained in the article, little of this is being done, largely because of a lack of funding. The unfortunate destruction of the Orbiting Carbon Observatory is also a contributing factor.
It is both saddening and surprising that so little funding is devoted to collecting this basic information, especially given that it could provide the earliest signs of significant changes in the functioning of the carbon cycle. For instance, it could identify things like the rate of methane release in the Arctic, or changes in the world’s carbon sinks. Greenhouse gases affect the climate system, regardless of whether they are released directly by human beings or whether humans merely induce their release indirectly. As such, top-down tracking is vital for developing and maintaining a comprehensive sense of what is going on.
In Canada, at least, the state of climate science funding seems to be worsening. While promises of a ‘High Arctic Research Station’ continue to be made periodically, the Polar Environment Atmospheric Research Laboratory (PEARL) is being shut down for lack of funding, and Canada’s climate scientists remain muzzled.
As climate change continues, the Arctic is warming more than any other part of the world. This year’s mild winter is having an effect on northern communities, by making ice roads they depend upon impassable. Now, a state of emergency has been declared:
Mild weather shut the roads down after just under a month, which cut off more than 30,000 people from the south. Normally, the 2,200 kilometres of temporary routes over frozen swamps, muskeg and lakes are open for up to eight weeks.
About 2,500 shipments of fuel, groceries, construction materials and general freight are brought in at a reasonable cost using winter roads. Otherwise, goods have to be flown in at great expense.
Of course, there has always been variation in the severity of winters, arising from the complexities of the climate system. What climate change does is shifts the distribution: making the mean winter warmer, and increasing the number of very unusually warm winters relative to very unusually cold ones.
The specific case of ice roads and Arctic communities also demonstrates a broader situation. Every community in the world has evolved into its current form based at least partly on the climate in which it exists. This includes everything from transportation and housing infrastructure to energy generation facilities and emergency response capacity. The more climate change takes place worldwide, the greater the mismatch will be between the climate communities were built for and the climate they actually experience.
Having already read a great deal about climate change and the Arctic, I expected Alun Anderson’s After the Ice: Life, Death, and Geopolitics in the New Arctic to provide only a moderate quantity of new information. I was quite surprised by just how much novel, relevant, and important content he was able to fit into the 263 pages. The book discusses the historical and current relations between governments and Arctic indigenous peoples; ice flow dynamics and exploration; the changing nature of Arctic ecosystems and species, along with information on what climate change may do to them; international law and the geopolitical implications of a melting Arctic; oil, gas, and other natural resources, and how their availability is likely and unlikely to change in coming decades; the rising tide of Arctic shipping, and the special safety and environmental considerations that accompany it; and the feedback effects that exist between a changing Arctic and a changing climate.
Ecosystems
Some of the best information on the book is about biology and Arctic ecosystems. It describes them from the level of microscopic photosynthetic organisms up to the level of the megafauna that gets so much attention. Anderson argues that most of the large marine mammals (seals, walruses, whales, etc) are threatened to some extent or another by the loss of sea ice. This is for several reasons. First, it could disrupt the lowest levels of the food web they rely upon. Second, it could permit the influx of invasive species that could out-compete, starve, or attack existing Arctic species. Third, the lifecycles of Arctic animals are slow and deliberate, and thus liable to disruption from faster-breeding competitors. Disappearing sea ice off Svalbard has already completely wiped out what was once “one of the best areas for ringed seal reproduction.” Arctic species, argues Anderson, will need to “move, adapt, or die.” Generalists like beluga whales have promise, while the narwhal and polar bear may be the most vulnerable large creature in the ecosystem.
One consequence of the loss of multi-year sea ice that I had not anticipated is the potential for a massive migration of species between the Pacific and Atlantic oceans, with invasive species potentially seriously altering the composition of ecosystems on both sides. Melting ice could therefore produce major changes in much of the world’s ocean. Even before that, expanded range for orcas could have a significant effect on life in northern waters. Where ice used to provide safety, by obstructing their pectoral fins, these powerful predators increasingly have free reign.
Resources, shipping, and tourism
Anderson makes an effective argument that most of the oil, gas, and resources in the Arctic will be effectively locked away for some time yet. There will always be ice in the winters, glacial ice calving off Greenland and other Arctic islands poses a significant risk due to its extreme hardness, and very high commodity prices are necessary to justify the risk and capital investment required to operate in the region. (See this post on the the Shtokman gas field.) He expects that, even if there is a boom, it will be short-lived and of limited benefit to those living in the region. In particular, he cautions people living in the north not to abandon traditional ways of life sustained by things other than oil and gas. Living for a couple of rich decades and then being left with nothing would be a tragic outcome.
The book also downplays fears about a scramble for resources and sovereign control. Anderson argues that the United Nations Convention on the Law of the Sea (UNCLOS) already provides a clear legal framework and that negotiated outcomes are probable. That should provide some comfort to those concerned about diplomatic or even armed conflicts in the changing north. One danger Anderson does highlight is how the risk of collision with ice, increasing shipping and tourist traffic, and the absence of emergency response capabilities could combine. He describes plausible scenarios where major oil spills or massive loss of life could result, due to a problem with a tanker or a cruise ship (disproportionately full of elderly people susceptible to cold, as they are).
While Anderson does an excellent job of explaining some of the risks to species and human beings from a changing Arctic, he doesn’t take seriously the possibility of truly radical or catastrophic change, of the kind highlighted as possible by James Hansen. Anderson also completely fails to describe how the incremental emissions from burning oil and gas in the Arctic would inevitably increase the degree of climate change experienced by humans and natural systems. It is cumulative emissions that matter most, and extracting hydrocarbons from the far north can only increase those.
For anyone with an interest in what is happening to the Arctic and what the medium- and long-term implications of that might be, this book is enthusiastically recommended.
That is the message from the Ontario Clean Air Alliance, expressed in a post on BuryCoal.com. They argue that Ontario has enough non-coal electricity generating capacity to put its four remaining coal plants on “standby reserve” between now and their legislated closure in 2014.
It is an initiative worth applauding. In contrast to targets so far off in the future as to be politically irrelevant, this is something that could be done right away. That is important, given the degree to which every year that passes before emissions peak means more drastic cuts will be required around the world afterward.
Another option worth considering is converting Nanticoke, North America’s largest coal-fired power plant, to burn biomass instead. From a health and environmental perspective, that’s not as appealing as shutting it down, but it would definitely be an improvement upon the status quo.
I have written previously about the climatic importance of black carbon – tiny particles of soot, mostly from burning diesel and biomass, that have a warming effect on the climate. This effect can be most acute when the black carbon falls on snow. It absorbs sunlight and accelerates melting. Andreas Stohl, from the Norwegian Institute for Air Research, has tracked pollution from satellite data and identified agricultural burning in Russia, Ukraine, Belarus, and Baltic states as major sources of black carbon that ends up in the Arctic. Stohl and others have also applied trajectory models to determine how pollution from different regions ends up in the Arctic.
As shipping routes become more open, with the vanishing of multi-year sea ice, diesel-burning ships risk becoming a larger source of black carbon in the region. As one paltry step towards slowing the demise of the Arctic as we know it, the coastal states of the Arctic ocean should insist on better particle traps for vessels, both by imposing standards for new construction and requiring retrofits. Germany, Austria, and Switzerland all already have legislation in place requiring such filters. In addition to the climatic benefits, such filters could also benefit human health. Investigations between 1993 and 1998 showed that such filters “can intercept at least 99% of the sub-micron particulates in the range of heightened pulmonary intrusion.”
Governments could also insist on the use of cleaner forms of diesel that generate less black carbon. It is bad enough that oil and gas exploration in the Arctic might accelerate warming – to say nothing of the risks from methane. We don’t need little low-albedo specks of soot making things even worse.
