Chaudiere Bridge and Domtar Mill

For two years, the Chaudiere Bridge and Domtar Mill were between home and work for me. Indeed, throughout Ottawa’s long winter bus strike (and much of the time in nicer months), I would walk through both most days of the week. The mill is mostly shut down now, though part of it has been converted into a run-of-river hydroelectric station.

While there are still security personnel and vehicles around, most of the mill seems to be shut down and locked up. The area is full of fences, locks, and barbed wire.

I love how malicious this lightning creature looks, striking down the small boy. It is certainly an effective warning sign.

High-pressure steam pipes run all around the complex. At regular intervals there are pressure release systems that vent steam every few seconds.

Both upstream and downstream, there are signs and barriers to warn boaters about the dam.

For several months last year, the Chaudiere Bridge was either closed or taking restricted traffic, because of concerns about its structural stability. Ottawa’s freeze-thaw cycles are brutal on infrastructure, especially roads and bridges.

I have always found bridges to be especially elegant and compelling structures. It has something to do with the mathematics of them, as well as the way in which they serve as an interface between human desires and the natural environments in which people live.

These green struts extend around the bridge, mostly supporting thick steam pipes that run between different parts of the mill.

Most of the metal in the area is corroded to one extent or another. Part of that must be the result of constant exposure to the salt used by the city to keep the roads and sidewalks relatively clear of ice in the winters.

Even on a Sunday evening, the bridge always has traffic. Walking to and from work may have contributed to my increasingly genuine hatred of automobiles. Single individuals, needlessly spilling greenhouse gases to propel themselves around in giant hulks of metal and glass, splashing and killing pedestrians and cyclists alike.

Even in the more remote accessible corners of the Domtar complex, you can see papers and personal effects behind windows. It is hard to tell whether these are active offices, or abandoned workspaces.

The complex is full of interesting structural details – power cables, girders, metal and concrete works built to constrain the flow of the river.

One of the taller Domtar buildings has been converted into an indoor climbing gym. As far as I can tell, this one has just been boarded up and abandoned.

On the eastern side of part of the complex, some sort of big recycling effort is underway. These girders may eventually find their way into something new.

The giant recycling bins themselves are corroded, with peeling paint and sharp edges.

Apparently, there were three previous Chaudiere bridges: 1827, 1845, and 1892.

Renewable energy and the budget

Tim Weis, from the Pembina Institute, does a good job of showing why Canada’s most recent budget is not well aligned with the government’s target on renewable energy, namely to move from generating 77% of our energy from non-emitting sources now (mostly hydro and nuclear) to generating over 90% that way by 2020. It’s a laudable goal, but one hardly advanced by the investment of a mere $25 million in renewable energy in the forestry sector, or continued inaction on the regulation of greenhouse gases.

If Canada is serious about becoming a “clean energy superpower,” we need to do better than this.

2010 SFT – climate and energy

Here are the sections from today’s Speech from the Throne (SFT) that relate to climate and energy:

“Our energy resource endowment provides Canada with an unparalleled economic advantage that we must leverage to secure our place as a clean energy superpower and a leader in green job creation. We are the world’s seventh largest crude oil producer with the second largest proven reserves. We are the third largest natural gas producer, the third largest hydroelectric generator, the largest producer of uranium, and by far the largest supplier of energy resources to the world’s largest marketplace. To support responsible development of Canada’s energy and mineral resources, our Government will untangle the daunting maze of regulations that needlessly complicates project approvals, replacing it with simpler, clearer processes that offer improved environmental protection and greater certainty to industry.”
“Our Government will continue to invest in clean energy technologies. It will review energy efficiency and emissions-reduction programs to ensure they are effective. And it will position Canada’s nuclear industry to capitalize on the opportunities of the global nuclear renaissance – beginning with the restructuring of Atomic Energy of Canada Limited.”
“The Joint Review Panel on the Mackenzie Gas Project has completed its report. Our Government will reform the northern regulatory regime to ensure that the region’s resource potential can be developed where commercially viable while ensuring a better process for protecting our environment.”
“Nowhere is a commitment to principled policy, backed by action, needed more than in addressing climate change. Our Government has advocated for an agreement that includes all the world’s major greenhouse gas emitters, for that is the only way to actually reduce global emissions. And it has pursued a balanced approach to emissions reduction that recognizes the importance of greening the economy for tomorrow and protecting jobs today.”
“The Copenhagen Accord reflects these principles and is fully supported by the Government of Canada. Together with other industrialized countries, Canada will provide funding to help developing economies reduce their emissions and adapt to climate change. Here at home, our Government will continue to take steps to fight climate change by leading the world in clean electricity generation. And recognizing our integrated continental economic links, our Government will work to reduce emissions through the Canada-U.S. Clean Energy Dialogue launched last year with President Obama’s administration.”

None of this is very encouraging. Rather than celebrating our huge fossil fuel reserves, we should be recognizing the risks associated with burning them. Similarly, brushing aside regulations that reduce the pace of fossil fuel exploitation will hardly help us avert catastrophic climate change.

The pledge to “review energy efficiency and emissions-reduction programs to ensure they are effective” is also discouraging. Canada still hasn’t deployed any sort of carbon price: a vital component of an overall climate change response.

Vancouver’s last Olympics?

Richard Brenne has written an interesting post on why climate change means 2010 was probably Vancouver’s last opportunity to host the winter Olympics:

Global warming is the reason Vancouver will never host another Winter Olympics. They barely dodged (biathlon) bullets at dozens of events, and the Olympic Committee would rather use Donald Trump’s hair as the Olympic flame than go through this again. Climate change is all about likelihoods of things like the record warmth Vancouver has had increasing, and the Olympic Committee rolled Jim Hansen’s dice and came up snake eyes.

He goes on to describe the extreme efforts taken to improve snow conditions, as well as the unusual circumstances in which events were conducted: from snowboard events on slushy runs to Nordic skiers racing in unprecedented temperatures.

The whole thing is worth reading.

Past lives of climate deniers

My friend Antonia sent me a nice article by Jeffrey Sachs, describing what today’s most prominent climate change deniers were doing, before they took up this cause:

Today’s campaigners against action on climate change are in many cases backed by the same lobbies, individuals, and organisations that sided with the tobacco industry to discredit the science linking smoking and lung cancer. Later, they fought the scientific evidence that sulphur oxides from coal-fired power plants were causing “acid rain.” Then, when it was discovered that certain chemicals called chlorofluorocarbons (CFCs) were causing the depletion of ozone in the atmosphere, the same groups launched a nasty campaign to discredit that science, too.

Later still, the group defended the tobacco giants against charges that second-hand smoke causes cancer and other diseases. And then, starting mainly in the 1980s, this same group took on the battle against climate change.

What this reinforces is how artificial the climate change denial movement is. Status quo actors, from Duke Energy to Saudi Arabia to Canada’s oil-sands-funded politicians, want to avoid climate change legislation. They have found some shills happy to spread confusion, in order to advance that aim. What is sad is how many ordinary people have lined up to be duped.

Medicare and populist opposition to reform

I had no idea that opposition to Medicare was so vociferous in Saskatchewan, when Tommy Douglas and the Co-operative Commonwealth Federation (CCF) party introduced it in 1962:

“The city’s residents had been whipped into a near-hysteria by the doctors’ anti-medicare campaign,” Margoshes writes, adding, “There were graffiti threats on city walls and calls in the middle of the night to Tommy’s house. His campaign manager, Ed Whelan, got frequent calls from a man threatening to ‘shoot you, you Red bastard!’ A few homeowners placed symbolic coffins on their front lawns.”

It goes to show what determined politicians with a clear objective can accomplish, even in the face of misinformation campaigns and a large amount of visible public opposition. Perhaps that is something that should give hope to climate change campaigners. If we ever get a government that is really serious about the issue, they might be able to push through the opposition of those seeking to maintain the status quo and develop policies that people will look back in with pride fifty years in the future.

That said, it also seems quite possible that a party that created a serious climate change policy would be punished for it in the short term, as the CCF was for Medicare. After its passage, they got smashed in the next election and remained out of power for seven years. That reminds me a bit of Stephane Dion, though he never got to implement his Green Shift plan, which was certainly bold in comparison to what we are doing at present on climate change.

Does Canada see the north as a colony?

Writing in The Globe and Mail, Doug Sanders makes the interesting and probably not inaccurate observation that Canada treats the far north like a colony:

We own the Arctic but, unlike most of our northern neighbours, we are not Arctic. Rovaniemi is a serious city of 60,000 people, with a major university, a large airport and important ties to the mainstream of Finnish life. Like the Arctic cities of Tromso, Norway (60,000) and Murmansk, Russia (325,000), it’s a major centre of business, learning and tourism.

So when Canada tried to impress the world’s finance ministers and media with its Arctic identity by holding a summit in Iqaluit, a remote and somewhat inaccessible town of 7,000 just below the Arctic Circle in Nunavut, it didn’t completely work. “It looked like the Canadians had just arrived there – they didn’t seem to know the place any better than we did,” one European official told me.

What those leaders realized, and what Canadians instinctively know, is that we relate to the Arctic not as a part of our identity or culture or traditional economy, but as a foreign, faraway land we happen to control. The Far North is, in short, our colony.

To me, it does seem plausible that both Canadian decision-makers and the Canadian public at large see the north through the twin lenses of romance about the place and excited anticipation about what good things we are going to be able to do with it, once that ice is less of a problem and we can get at the shipping routes and fossil fuel resources.

The profound transformation of the Arctic is now all-but-inevitable, probably to an extent that few people realize. It will be interesting to see whether the inhabitants start taking a stronger and more visible stance once it becomes inescapably obvious that the whole region is being transformed, or whether they will just take that as a given and start scrambling for a share of oil and gas revenues.

‘Rotten’ multi-year ice

Because of the tilt of the Earth, the polar regions will always be cold in the winter. What is changing in the Arctic is the amount of ice that can endure through the summer months. Ice that has survived two winters is said to be ‘multiyear’ ice. Because more salt has been forced out from it, it is harder than younger ice. That makes it more durable, as well as a greater hazard to ships. While the decline in the overall extent of Arctic sea ice has been dramatic, the decline in the extent of multiyear ice has been even more so. This animation shows it vanishing over the past 30 years.

Furthermore, at least some scientists believe that most of the melting taking place has been from the bottom, and anecdotal reports from people operating icebreaking ships suggest that the multiyear ice still out there isn’t the same thing as what existed before. It is riddled with brine channels and weaker, and sometimes just consists of a thin layer of young ice covering small chunks of old ice. As such, it is more vulnerable to melting. This weak and vulnerable ice can provide a false impression of strength, when viewed from space. David Barber, Canada’s Research Chair in Arctic System Science at the University of Manitoba, has explained to Parliament that “we are almost out of multiyear sea ice in the northern hemisphere.”

While the loss of sea ice may be welcome to those seeking a transpolar shipping route, or the chance to drill for oil and gas, it is definitely bad news for the charismatic megafauna with lifestyles critically dependent on sea ice. Seals need it in order to rear their pups, while polar bears need it to hunt seals. The total loss of summer sea ice would probably spell the doom for both species in the wild.

Sea ice monitoring in Canada

I recently had occasion to learn a bit about how the Canadian Ice Service operates: tracking ice and oil slicks in the Pacific, Arctic, and Atlantic oceans. They rely on a couple of satellites – RADARSAT I and II – which are primarily synthetic aperture RADAR instruments (though they also passively observe microwave emissions from ice, which are useful for differentiating young ice from the harder multi-year sort). They also have three aircraft to cover gaps between satellite passes, as well as collect evidence of ships discharging oil, for later prosecutions. They are also the ones who put the beacon I mentioned earlier on the ice island that calved from the Petermann Glacier.

As the Arctic continues to lose old ice and summer ice, their role will only become more important. Sea traffic of all sorts is likely to increase, particularly if a trans-polar route opens up in summertime (not through either channel of the Northwest Passage, but straight across the pole) or if major oil and gas discoveries occur in the increasingly clear Arctic ocean.

Rebutting Wente

Writing in The Globe and Mail, World Wildlife Fund President Gerald Butts has done a good job of expressing what is and is not important about the recent errors in IPCC reports that have gotten so much attention and rekindled the fires of the climate change denier community:

Yes, some scientists showed poor judgment in private e-mail exchanges later hacked and made public. Yes, some errors in fact and incomplete citations have been found in the IPCC’s 1,000-page reports. That said, even scientists who have criticized the IPCC agree that anthropogenic climate change is both a fact and an urgent threat to the planet.

All independent reviews undertaken so far (by The Associated Press, the University of Michigan and The Economist, for example) agree that none of the stolen e-mails or errors bring into question the science supporting climate change. To conclude otherwise is to misunderstand the process and power of science, and to dismiss the need to draw on the best available evidence and consensus to guide national policies.

Science is not a cold body of facts, but an organized system of inquiry, discovery, evaluation and learning. Science not only welcomes the correction of errors, its key attribute is that it is self-correcting over time. As new research arises, old hypotheses gain or lose support. While this process never stops, generally accepted conclusions do accumulate, based on the overwhelming weight of evidence. The fact and threat of anthropogenic climate change are clearly among those conclusions.

It is encouraging to see such an effective rebuttal printed to Margaret Wente’s misleading recent column, though it remains dispiriting that The Globe and Mail is still happy to give a platform to people as irresponsible and scientifically illiterate as Wente and Rex Murphy. Wente’s column is a prime example of a position that – on first glance – appears prudent, in suggesting that we shouldn’t take serious action while there still seem to be scientific uncertainties about climate. Unfortunately, the known characteristics of the climate system make this position irresponsible. The full effect of emissions today will take decades to fully manifest, and the climate system has the capacity to amplify small changes into much larger outcomes. What we know about the history and character of Earth’s climate tells us we need to take action now, not at some future point when the faulty claims of deniers have finally been deflated in the eyes of the public.

I suspect that, a few decades from now, people will be puzzled about why we were so unable to separate signal from noise, when it came to hearing what scientists were saying about climate change. Part of that is surely the result of actions taken in bad faith by those seeking to prevent policy action (people quite capable of exploiting the peculiar phenomenon that arise at the intersection of science and the media). That said, much of the explanation has to lie with the complacency of a public happy to hear that no action is required at the moment, no matter how thin the credibility of those making this announcement.
