- After Nigel Wright and then Ben Perrin’s testimony at the Mike Duffy trial, I am pretty confident that Stephen Harper was lying about not knowing about the payment. The plausible deniability seems less plausible every day. Or as Andrew Coyne sarcastically suggests, maybe Stephen Harper is a victim in all of this.
- Far more Liberal lawn signs visible in Saskatoon since 1993 when Jean Chretien swept to power. In many ways the shift to the Liberals has to be really good for the Conservatives as I think this comes from historic NDP vote. That being said, I still think Saskatoon West goes to the NDP.
- The interesting race may be Saskatoon Grasswoods and Saskatoon University. Kevin Waugh has been really quiet so far while everyone is asking where Brad Trost is. Trost doesn’t even have a website (although he has a web domain that goes nowhere). It’s early but the Conservatives could go 0-3 in the city.
- I also found it weird that Jason Kenney was in town last night for a fundraiser for Donauer and Block only and not for the east side candidates.
- I watched Antarctic Edge: Beyond the Ice last night which is on the rapid global warming that is happening in Antarctica right now. Winter sea ice has declined by three months and temperatures have increased by 11 degrees Fahrenheit, six times greater than the global average. Yet the NDP and the Liberals seem nervous about talking about it. Maybe it is an acknowledgement that Canada is indeed what most of the world is calling us, a petro-state (or to throw it back to the 80s; PetroCanada). Our entire country has become tied to oil and gas revenue. To tackle climate change in a serious way, it would cause a serious disruption to the Canadian economy and throw hundreds of thousands out of work. In a day and age where the “middle class” is king politically, no one wants to take a stand that would hurt them, even if it hurts the globe.
- Interesting interview on The Current with John Ibbitson. It’s worth the 20 minutes to listen to it. You may even want to listen to it again.
- In some way I feel sorry for the political staffers who have to create election material and use stock photos. They have no budget and are under time constraints and it never turns out well. Never ever turns out well.
- This won’t come up in the election but I tend to give Stephen Harper a pass for messed up military procurement, especially when the Americans who do it better than we do, also have their struggles.
- Whoever wins, is going to have a tougher go with the Canadian economy. Oil prices are to stay depressed for another two years.
- The NDP minimum wage hike makes claims that it can’t back up. Hey, a NDP populist economic policy that makes no sense, what a surprise.
- Of course neither leader has the courage to wade into Saskatchewan’s most pressing issue, what’s wrong with the Roughriders?
In Rolling Stone, Eric Holthaus writes that as far as climate change is concerned, we are already past the point of no return. The things climate scientists have warned against are already beginning to happen…and faster than predicted.
Hansen’s new study also shows how complicated and unpredictable climate change can be. Even as global ocean temperatures rise to their highest levels in recorded history, some parts of the ocean, near where ice is melting exceptionally fast, are actually cooling, slowing ocean circulation currents and sending weather patterns into a frenzy. Sure enough, a persistently cold patch of ocean is starting to show up just south of Greenland, exactly where previous experimental predictions of a sudden surge of freshwater from melting ice expected it to be. Michael Mann, another prominent climate scientist, recently said of the unexpectedly sudden Atlantic slowdown, "This is yet another example of where observations suggest that climate model predictions may be too conservative when it comes to the pace at which certain aspects of climate change are proceeding."
Since storm systems and jet streams in the United States and Europe partially draw their energy from the difference in ocean temperatures, the implication of one patch of ocean cooling while the rest of the ocean warms is profound. Storms will get stronger, and sea-level rise will accelerate. Scientists like Hansen only expect extreme weather to get worse in the years to come, though Mann said it was still "unclear" whether recent severe winters on the East Coast are connected to the phenomenon.
With non-linear events like climate change, things happen slowly then suddenly. We are now experiencing “suddenly”.
It’s odd that despite the rhetoric around climate change, none of the three parties are planning on doing much about it. The NDP and Liberals are promising to do more then the Conservatives but none of the three parties are doing that much and in many ways the policy of the NDP and Liberals is shaped by the poor performance of what the Conservatives have done. Being better then Stephen Harper isn’t enough.
â€œThese future droughts are not only going to be bad compared to what weâ€™ve experienced over the historical period, but also really bad compared to the past millennium,â€ says Benjamin Cook, a drought researcher at NASAâ€™s Goddard Institute for Space Studies in New York City, who led the work. â€œItâ€™s going to be a pretty much fundamental shift.â€
Much of North America has a long and detailed climate history, thanks to tree rings that preserve records of temperature and rainfall. Many scientists have used these to piece together the story of decades-long droughts, like one that gripped the US Southwest in the thirteenth century and probably contributed to the disappearance of ancient Pueblo peoples. Others have used global climate models to study the regionâ€™s future, and found that it may already be transitioning to a fundamentally drier state.
Cookâ€™s team aimed to bridge past and present. The scientists compared 1,000 years of North American climate history with future projections from 17 different climate models â€” â€œas many as we could get our hands on that gave us the data we neededâ€, Cook says.
Among other metrics, the researchers looked at a measure known as the Palmer Drought Severity Index, which is an indicator of soil moisture. Some scientists criticize the Palmer index because it can overestimate future drying if it is calculated on the basis of temperature projections alone. To get around this problem, Cookâ€™s team used a different method of calculating the index, one that incorporates humidity and energy from sunlight.
Kevin Anchukaitis, a palaeoclimatologist at the Woods Hole Oceanographic Institution in Massachusetts, says that the revised method gives a much more accurate projection of how dry things will really get. â€œThis is the first convincing demonstration Iâ€™ve seen that it is both possible to seamlessly connect past, present and future, and to then be confident that they are on comparable scales,â€ he says.
At the rate things are going, the Earth in the coming decades could cease to be a â€œsafe operating spaceâ€ for human beings. That is the conclusion of a new paper published Thursday in the journal Science by 18 researchers trying to gauge the breaking points in the natural world.
The paper contends that we have already crossed four â€œplanetary boundaries.â€ They are the extinction rate; deforestation; the level of carbon dioxide in the atmosphere; and the flow of nitrogen and phosphorous (used on land as fertilizer) into the ocean.
â€œWhat the science has shown is that human activities â€” economic growth, technology, consumption â€” are destabilizing the global environment,â€ said Will Steffen, who holds appointments at the Australian National University and the Stockholm Resilience Center and is the lead author of the paper.
These are not future problems, but rather urgent matters, according to Steffen, who said that the economic boom since 1950 and the globalized economy have accelerated the transgression of the boundaries. No one knows exactly when push will come to shove, but he said the possible destabilization of the â€œEarth Systemâ€ as a whole could occur in a time frame of â€œdecades out to a century.â€
The researchers focused on nine separate planetary boundaries first identified by scientists in a 2009 paper. These boundaries set theoretical limits on changes to the environment, and include ozone depletion, freshwater use, ocean acidification, atmospheric aerosol pollution and the introduction of exotic chemicals and modified organisms.
Beyond each planetary boundary is a â€œzone of uncertainty.â€ This zone is meant to acknowledge the inherent uncertainties in the calculations, and to offer decision-makers a bit of a buffer, so that they can potentially take action before itâ€™s too late to make a difference. Beyond that zone of uncertainty is the unknown â€” planetary conditions unfamiliar to us.
â€œThe boundary is not like the edge of the cliff,â€ said Ray Pierrehumbert, an expert on Earth systems at the University of Chicago. â€œTheyâ€™re a little bit more like danger warnings, like high-temperature gauges on your car.â€
ON NOVEMBER 2ND the Intergovernmental Panel on Climate Change (IPCC), which represents mainstream scientific opinion, said that it was extremely likely that climate change is the product of human activity. Extremely likely in IPCC speak means having a probability of over 95%. The claim forms part of its fifth assessment on the state of the global climate. In its first assessment, in 1990, the IPCC had said that “the observed increase [in air temperatures] could be largely due to natural variability.” Why have climate scientists become so much more certain that climate change is man-made, not natural?
Many factors influence the climate but perhaps the single most important is carbon dioxide (COâ‚‚). COâ‚‚ absorbs infra-red heat at a constant rate and at a higher rate than nitrogen and oxygenâ€”the main constituent parts of the atmosphereâ€”so the more COâ‚‚ in the air, the more the atmosphere will tend to warm up. Scientists attribute climate change to human activity mainly because people have been responsible for large increases in COâ‚‚. At the start of the industrial revolution, in about 1800, there were 280 parts per million (ppm) of COâ‚‚ in the atmosphere. That had been the level for most of human history. This year, however, concentrations exceeded 400 ppm, the first time it had reached that level for a million years.
Most of the increase has been caused by people burning fossil fuels. In the United States, for example, 38% of the COâ‚‚ produced in 2012 came from generating electricity and 32% came from vehicle emissions (the rest came from industrial processes, buildings and other smaller COâ‚‚ production). People also produce COâ‚‚ when they cut down forests for farmland and pasture
The Earth is locked on an â€œirreversibleâ€ course of climatic disruption from the buildup of greenhouse gases in the atmosphere, and the impacts will only worsen unless nations agree to dramatic cuts in pollution, an international panel of climate scientists warned Sunday.
The planet faces a future of extreme weather, rising sea levels and melting polar ice from soaring levels of carbon dioxide and other gases, the U.N. panel said. Only an unprecedented global effort to slash emissions within a relatively short time period will prevent temperatures from crossing a threshold that scientists say could trigger far more dangerous disruptions, the panel warned.
â€œContinued emission of greenhouse gases will cause further warming and long-lasting changes in all components of the climate system, increasing the likelihood of severe, pervasive and irreversible impacts,â€ concluded the report by the United Nationsâ€™ Intergovernmental Panel on Climate Change (IPCC), which draws on contributions from thousands of scientists from around the world.
The report said some impacts of climate change will â€œcontinue for centuries,â€ even if all emissions from fossil-fuel burning were to stop. The question facing governments is whether they can act to slow warming to a pace at which humans and natural ecosystems can adapt, or risk â€œabrupt and irreversible changesâ€ as the atmosphere and oceans absorb ever-greater amounts of thermal energy within a blanket of heat-trapping gases, according to scientists who contributed to the report.
Meanwhile in Canada, we donâ€™t care about climate change, only our own economy.
Canada’s hopes of securing an outlet for its landlocked oil wealth and pulling an end run around the eternally deadlocked Keystone XL project took a big step forward Thursday with the release of formal plans to build a U.S. $11 billion pipeline to the Atlantic.
TransCanada, the biggest Canadian pipeline company, submitted its application to Canadian energy regulators for a nearly 3,000-mile-long, million-barrel-a-day pipe running from oil-rich western Canada to refineries and shipping terminals in the east. The so-called Energy East Pipeline Project, which TransCanada officials hope could be in operation as soon as 2018, would provide an export outlet for huge volumes of current and future oil production that right now has no easy way to get to market.
The project wouldn’t replace the Keystone XL pipeline — Canada’s other high-profile, multibillion-dollar oil-transport project, which has been awaiting U.S. approval for years — but it could give Republican critics of U.S. President Barack Obama’s administration fresh fodder ahead of the midterm elections. Republicans have long argued that the White House’s refusal to sign off on the Keystone project would cost the United States tens of thousands of jobs. The Obama administration has finished reviewing the environmental merits of Keystone, but pushed back any decision until later this year or early 2015.
If the new Canadian route gets approved in 2016 by Canada’s National Energy Board, as TransCanada expects, it would give the eastern provinces a source of domestic oil — removing the need for some 700,000 barrels a day of oil imports — and would give producers in Alberta and Saskatchewan a direct route to big refineries that could turn the sludgy tar sands into valuable products such as diesel, gasoline, and jet fuel.
On any given day, Johannes van Bergen, director of the municipal utility Stadtwerke SchwÃ¤bisch Hall in southwestern Germany, conducts his team’s array of gas, heat, and electricity sources to meet the energy needs of at least several hundred thousand Swabians in the region, as well as about more than 90,000 customers elsewhere in Germany. And every day — in fact, every hour — that energy mix is constantly in flux.
Technicians at the town’s smart-grid center monitor and manage the utility’s roughly 3,000 regional energy suppliers: several thousand solar photovoltaic (PV) installations, two wind parks, one gas-and-steam power station, six small hydro-electric works, three biomass (wood pellet), sixbiogas plants, and 48 combined heat and power plants, as well as other conventional and renewable energy suppliers outside the municipality.
The population that this ballet of coordinated energy sources serves is admittedly modest, but it’s here that the future of Germany’s energy industry is being tested in full — and proven.
Which of course is a model that we could use here but for whatever reason, the province and the country isnâ€™t willing to experiment.
Their output, and increasingly that of the conventional, too, is distributed through a tightly knit, cross-border smart grid. The composition of supply changes from minute to minute depending on weather, demand, and other factors from one corner of the country to the other. Increasingly electricity is generated in and traded from locality to locality, and even across the country (or countries) via intelligent networks much like that in SchwÃ¤bisch Hall and other places in Germany.
No one predicted this scale of locally driven, citizen-led energy boom when the Energiewende began. Even just four years ago, just about everybody involved in the Energiewende thought that big-ticket projects like enormous offshore wind farms planned for Germany’s northern seas and Desertec, the mega-project to import solar energy across the Mediterranean from sprawling concentrated solar power arrays in the Middle East and Northern Africa, would be integral to Germany going renewable.
These projects, however, have flopped spectacularly.
Offshore wind has proven extremely pricey and technologically much trickier than originally assumed, which has led to billons in cost overruns and years-long delays. Germany’s seven operational offshore parks constitute a tiny fraction — just 0.6 percent — of the country’s renewably generated electricity, compared to onshore wind’s 34 percent. The offshore industry claims there’s smooth sailing for offshore wind just around the corner, but it’s been saying that for years.
The president of the Pacific atoll nation of Kiribati, which averages only about 2 meters above sea level, has already spent millions of dollars to buy land in Fiji as a potential new home for his 100,000 people. As sea levels rise, the Intergovernmental Panel on Climate Change suggests, large ocean waves will increasingly taint the countryâ€™s groundwater and threaten its agriculture; Kiribati can expect to become at least partly uninhabitable long before seas rise enough to submerge it. Other island nations like the Maldives and Tuvalu face the same plight.
So far, the worldâ€™s attention has rightly focused on how much these places have to lose: their homes, their communities, their cultures, their vistas. But these countries have another, less visible set of assets at stake as they consider their survivalâ€”assets that wonâ€™t necessarily be lost, but which raise substantial questions. These are their large and valuable maritime zones.
Kiribati, like other island nations, controls hundreds of thousands of square miles of the ocean that surrounds it. Kiribatiâ€™s land area is about that of Kansas City, while the ocean territory it controls is larger than India. Within these â€œexclusive economic zones,â€ to use the UN term, island nations possess the power to regulate, tax, or disallow any economic activity, including mining or drilling for oil. The tuna fishing alone in the domain of Pacific island nations is worth an estimated $4 billion a year.
There are several potential explanations for whatâ€™s going on here. The most likely is that some combination of increasingly infrequent summer snowstorms, wind-blown dust, microbial activity, and forest fire soot led to this yearâ€™s exceptionally dark ice. A more ominous possibility is that what weâ€™re seeing is the start of a cascading feedback loop tied to global warming.
Box mentions this summerâ€™s mysterious Siberian holes and offshore methane bubbles as evidence that the Arctic can quickly change in unpredictable ways.
This year, Greenlandâ€™s ice sheet was the darkest Box (or anyone else) has ever measured. Box gives the stunning stats: â€œIn 2014 the ice sheet is precisely 5.6 percent darker, producing an additional absorption of energy equivalent with roughly twice the US annual electricity consumption.â€
Perhaps coincidentally, 2014 will also be the year with the highest number of forest fires ever measured in Arctic.
Box ran these numbers exclusively for Slate, and what he found shocked him. Since comprehensive satellite measurements began in 2000, never before have Arctic wildfires been as powerful as this year. In fact, over the last two or three years, Box calculated that Arctic fires have been burning at a rate thatâ€™s double that of just a decade ago. Box felt this finding was so important that he didnâ€™t want to wait for peer review, and instead decided to publish first on Slate. Heâ€™s planning on submitting these and other recent findings to a formal scientific journal later this year.

Meet the tiny, translucent “sea butterfly,” whose home is currently being transformed into an acid bath. Off the US’s west coast, there are anywhere between 100 and 15,000 of these free-swimming sea snails per square meter. And the oceans are beginning to dissolve the tiny shells right off their backs.
A new study, among the first to examine how the process called ocean acidification impacts marine life, has confirmed that about half of all the pteropods off the west coast are fighting off the acid burn. It builds on previous work that has shown pteropods dissolving in other waters; it’s a disturbing trend, considering they’re a key link in the oceanic food chain.
The world’s oceans have absorbed a third of humans’ carbon emissions, a process that increases their acidity. Scientists have long noted the changing chemistry of the waters, and voiced concern that this leaves calcium-based creatures, like coral and pteropods, extremely vulnerable. Now, it appears, they have proof.
“These are some of the first insights into how marine creatures are affected by acidification,” Dr. Nina Bednarsek told me in a phone interview. She’s the lead author of the National Oceanographic and Atmospheric Administration study, which was just published in the Proceedings of the Royal Society B. The research determined that “large portions of the shelf waters are corrosive to pteropods in the natural environment.”
“Fifty percent of those pteropods are affected by acidification,” Bednarsek said. “It’s a lotâ€”more than we expected.” And sooner. She tells me that acidification is happening sooner and on a larger scale than scientists predicted. “This is just an indication of how much we are changing the natural environment,” she said.
The â€œIf global warming is real, then why is it cold out?â€ line of argument has been around since the early days of the climate change debate, but the positively Hoth-esque temperatures have increased the volume of those hoping to undercut the â€œinconvenient truthâ€ of anthropogenic global warming. So, does the recent spate of cold snaps prove Al Gore a filthy, PowerPoint-loving, Oscar-winning liar? No. Sorry, Donald.
Most obviously, climate is different than weatherâ€”thatâ€™s why the Midwest and Northeast have faced three snowstorms in the past two weeks while the drought in California has been so severe that water deliveries from reservoirs to the Central Valley have been cut to zero. Climate trends are exactly that: trends. One swallow doesnâ€™t make a summer, and one blisteringly cold month doesnâ€™t prove 97 percent of climate scientists wrong.
Another key component of â€œglobal warmingâ€ is right there in the name: â€œglobal.â€ In December 2013, North America was colder than average, but Russia and most of Europe were far hotter. Despite what Ted Cruz thinks (or wants), the world extends beyond the continental United States, and most of it has been crazy hot. For every cold snap in the U.S., thereâ€™s a wildfire in Australia so intense that it creates its own weather.
Itâ€™s also important to note that although, baby, itâ€™s cold outside, itâ€™s not nearly as cold as it was generations ago. The East River froze at least a dozen times between 1780 and 1888. In fact, after a particularly hard winter in 1866-1867, frustration with halted ferry service eventually led to the construction of the Brooklyn Bridge. As webcomic xkcd noted, St. Louis, once the frozen home to a handful of sub-zero temperatures every year, hasnâ€™t had a day that cold since the 1990s. Thatâ€™s the thing about extreme weather: Itâ€™s extreme. The colds get colder, the hots get hotter, and the hurricanes get more destructive.
Prime Minister Stephen Harper has sent a letter to U.S. President Barack Obama formally proposing “joint action to reduce greenhouse gas emissions in the oil and gas sector,” if that is what’s needed to gain approval of the Keystone XL pipeline through America’s heartland, CBC News has learned.
Sources told CBC News the prime minister is willing to accept targets proposed by the United States for reducing the climate-changing emissions and is prepared to work in concert with Obama to provide whatever political cover he needs to approve the project.
The letter, sent in late August, is a clear signal Canada is prepared to make concessions to get the presidential permit for TransCanada Corp.’s controversial $7-billion pipeline, which will connect the Alberta oilsands to refineries in Texas.
From Mountainfilm in Telluride, a ragtag crew sails deep into a fjord in Greenland. The water channel, iced over for millenia, is open to exploration only because of global warming.
Guatemala’s president declared a national emergency Friday over the spread of coffee rust, saying the fungus that has hit other Central American countries is affecting 70 percent of this nation’s crop.
President Otto Molina Perez ordered the release of more than $14 million to aid coffee growers. He said the funds would help 60,000 small farmers buy pesticides and also finance instruction to teach them how to prevent the disease and stop it from spreading.
“If we don’t take the needed measures, in 2013-2014 our production could drop by 40 percent,” Molina said in making his country the third in the region to decree emergencies in recent weeks.
Coffee rust, which can kill plants by withering their leaves, also is affecting plantations in El Salvador, Honduras, Panama and Costa Rica. Mexico’s agriculture authorities said the fungus has been detected there but so far has not damaged plants.
Molina said the pesticides will start being applied to coffee plants in April and two more applications will be needed during the year.
Nils Leporowsky, president of the National Coffee Association of Guatemala, or Anacafe, said coffee is grown in 206 of the country’s 333 municipalities.Â
“We have planted 667,000 acres (270,000 hectares) of coffee and of that 477,000 acres (193,000 hectares) have rust, affecting 70 percent of the total,” he added.
Leporowsky said coffee growing generates 500,000 direct jobs as well as 700,000 additional jobs in related businesses each year.”We have lost 100,000 direct jobs already and that will affect millions of people,” he said.
Experts say the fungus has been present in Central American since the 1970s but production hadn’t previously been affected so severely as what is feared this year.
Otto Cabrera, an adviser with Anacafe, said coffee rust arrived in Guatemala in the 1980s.
“The fungus directly affects coffee leaves, initially with yellow spots that later turn orange and reaches around the foliage of coffee, then makes the leaves fall,” he said. “The plant loses its foliage. It’s not able to breathe, so it ceases producing and it eventually dies.”
Cabrera said climate change has brought a rise in average temperatures of about 2 degrees Celsius in Central American areas where the fungus was present, encouraging its growth and increasing the threat of severe damage.
In the postwar era, suburbanites ruled by the power of the ballot, and governments were forced to react to their concerns.
It’s also significant that the events in Saskatoon coincided with a report from the U.S. National Snow and Ice Data Centre in Colorado, which said that by mid-September the polar ice cap had retreated to historic levels, shattering the record retreat from 2007 and threatening to leave an ice-free Arctic decades sooner than expected.
The old way of building cities for automobiles is no longer on, Mr. Greenberg said. Except, as Saskatoon grows, that is exactly what is happening. Its suburbs still spread out in all directions, with large homes, two-vehicle-garages and car dependent citizens.
This isn’t only happening within city limits, where planners and city councillors are trying to adjust development patterns to favour denser development, but it’s happening past Saskatoon’s fringes where rural politicians argue that the city has no right to rain on their parade of sprawl.
The true test of Mr. Greenberg’s theory of a paradigm shift won’t just be the willingness of young citizens to sacrifice a Thursday evening to hear him. The test will be if they inform civic politicians on the hustings of their visions, if they turn out on Oct. 24 to mark their ballots, and if they spread the message those provincial and federal politicians and business leaders who are claiming that there is no difference between urban or rural interests.
Svalbard is an archipelago high within the Arctic Circle. The largest of its islands is called Spitsbergen, meaning â€œpointed mountains.â€ In 1920 a treaty known as the Svalbard Act was signed by several nations recognizing Norwegian sovereignty over the islands, and declaring the whole region a demilitarized zone. This is a short film about how Svalbard, over the course of recent history, became increasingly linked to developments in climate science, and climate change.
