Harper Government Takes Muzzling Scientists to New Extreme

Share

Machiavelli would approve. So would Stalin, Mao Zedong, the ayatollahs of Iran, Robert Mugabe of Zimbabwe and Bashar al-Assad of Syria. George Orwell would proudly place the audacity of information control in the Ministry of Truth, the agency in his dystopian 1984 novel in which Big Brother uses the Thought Police as the instrument that determines right from wrong, good from bad, wise from foolish, fact from fiction, reality from illusion.

Reality is shaped by information. Control information and reality is controlled. Eliminate information and the blank slate of public consciousness is vulnerable to suggestion and manipulation. Reality is, in effect, an immensely valuable but incredibly fragile commodity, forever changing as information changes. Little wonder, then, that those with a special interest in power also have a special interest in controlling information.

This would be an academic subject befitting a university class on ethics, philosophy or politics if it were not surfacing in Canada because of the Privy Council’s muzzling of scientists associated with the federal government through employment or grants. The strictures on what scientists can publicly say or publish, put in place by the Prime Minister’s office, have been tightening in recent years. In 2011 scientists protested and collectively complained that they could not speak openly to Canadians about their research and findings without receiving prior approval from the upper echelons of government—a dramatic break from the traditional freedom that is an assumed liberty in an open, modern and democratic society. Now the strictures are tightening further.

“As of February 1st this year,” writes Elizabeth May in Island Tides, (Feb. 28/13), “new rules were put in place requiring that scientists working on projects in conjunction with DFO in the Central and Arctic Region to treat all information as proprietary to DFO and — worse — await departmental approval before submitting research to any scientific journals.” A week later, on February 7th, additional rules were imposed requiring that “now they must obtain prior consent before applying for research grants” (Ibid.).

In Elizabeth May’s assessment of the tightening controls on scientists and their research, the process and its intent is obvious. “The tightening of control over science must be established far earlier in the process. Stop research from being submitted to journals. Stop scientists from collaborating with others. Stop scientists from applying for research grants. Stop science from happening at all” (Ibid.). This tragedy is compounded by strictures that constrain scientists from complaining about the constraints placed on them.

An American scientist, Dr. Andrew Muenchow, who has been doing important collaborative research with DFO in the Eastern Arctic since 2003, has refused to accept the new conditions, politely calling them a “potential muzzle”. The dissemination of crucially important information from Dr. Kristi Miller on viral diseases arriving in Canadian waters from salmon farming has been obstructed by the government authorities. Scientists researching ozone depletion, Arctic ice melt, pollution and species loss have been silenced. These are typical examples of the control of information by the Privy Council, an adjunct of the Prime Minister’s office. And it contrasts dramatically with the earlier protocol in which, “Data and any other project-related information shall be freely available to all Parties to this Agreement and may be disseminated or published at any time” (Ibid.). The Iron Curtain and the Berlin Wall have appeared in Canada as a blackout on any scientific studies that may conflict with the direction of government’s agenda.

This is not a mere scientific issue. Although science should be the basis upon which governments make many important legislative and policy decisions, open and free scientific research is the most obvious measure of an open and free society, one in which evidence is given precedence over ideology, and decisions are weighted and made as rationally and intelligently as possible from the best available information. Control information and decisions can be shifted toward ideology, the unexamined opinions that drift away from enlightened guidance toward blind bigotry.

Granted, governments make decisions and devise legislation based on their particular ideological bent. But this ideology must be guided by credible information. And a substantial portion of this information now comes from scientific research, collaboration, study and findings. Opinion untempered and unguided by science lacks credibility because it isn’t connected to an empirical measure of circumstances. Ideology that is untested and incompatible with evidence is medieval, for it bears little relationship to reality. Government strategy and legislation founded on uninformed opinion will invariably be flawed and dysfunctional. Even worse, the result is a burden of liabilities, faulty strategies, defective laws and missed opportunities that can be incredibly costly to a country, to its citizens and to the environment that sustains them.

The laws of science don’t change to suit political and economic agendas. Pretending that greenhouse gas emissions are not changing weather, that the Arctic is not warming, that pollutants don’t harm ecologies, and that crucial ecosystems are not under threat is denial bordering on the delusional and pathological. Scientists don’t invent what is happening to our world; they measure, witness and report to us. Muzzling their effort silences evidence and increases our vulnerability to environmental ruin.

As Elizabeth May so eloquently concludes, this suppression of the free exchange of scientific information in Canada “is the 21st Century equivalent of the Dark Ages. This is book burning and superstition run rampant. This is the administration of a steady, slow drip of poison to a weakening democracy” (Ibid.).

10 Ways to See Earth's Temperature Rising

10 ways to see Earth’s temperature rising

The subject of global climate change is critically important, irresistibly fascinating and incredibly complex. The following are relevant slices of information on this amazing subject.

1. According to the science journal, Nature, predictions of global temperature increases made by leading climatologists in 1990 have proven to be incredibly accurate. They estimated that from 1990 to 2030, the global temperature increase caused by greenhouse gas emissions would be 1.1°C — it was 0.39°C at the halfway point in 2010. The second 20-year period allows for slightly higher rate of increase because of the delayed response of ecosystems to existing carbon dioxide emissions and the effect of continuously higher emissions throughout most or all of the 20-year period. This would bring the global temperature increase well above the 2.0°C considered safe.

2. Human emissions of carbon dioxide into Earth’s atmosphere in 2011 were 34.7 billion tonnes, up about 1 billion tonnes from the previous year. If billions are too big to comprehend, these total emissions translate into 1,100 tonnes per second — about the weight of 500 cars dissolving into the atmosphere 60 times every minute (Globe and Mail, Dec. 4/12).

3. In addition to supplying a valuable nursery for many of the ocean’s small animals and fish, scientists have discovered that for thousands of years seagrass ecosystems have been locking an estimated 27.4 million tonnes of CO2 annually into marine soils — as much per hectare as forests. But dredging, pollution and siltation are destroying these seagrass ecologies at a rate of 1.4 percent per year, releasing about 299 million tonnes of CO2 into the atmosphere annually. Scientists worry that expanding dead zones, global warming and ocean acidification caused from burning fossil fuels may ultimately kill these special ecologies. Dying seagrass ecologies would eventually release the 19.9 billion tonnes of carbon dioxide presently stored in them (NewScientist, May 26/12).

4. Australia’s summer of 2012 has been exceptionally hot and dry. Temperature records kept since 1883 have been shattered. New South Wales and Tasmania are suffering from extensive wild fires. After labelling the increasingly threatening conditions as “serious”, “dangerous” and “critical”, scorching temperatures of 45°C with winds of 100 km/hr have prompted fire officials to add “catastrophic” to their ascending order of warnings. A code “purple” has been added to the warning system for temperatures above 50°C.

5. In April, 2012, for the first time in human existence, the mean concentration of measured atmospheric carbon dioxide throughout the Arctic and in Japan reached 400 parts per million. The levels usually peak about April before plants begin to absorb carbon dioxide during their annual growth cycle. The year-long average for 2012 will likely drop to about 393 ppm, up considerably from the 280 ppm that preceded industrialization. Pieter Tans of the US National Oceanic and Atmospheric Administration’s Earth System Research Laboratory concedes he doesn’t know the level that can be deemed safe. But he says that by continually raising this concentration, “We’re playing a very dangerous game” (NewScientist, June 9/12).

6. Some of the huge quantities of carbon dioxide emitted into the atmosphere from burning fossil fuels eventually dissolve into the oceans to form carbonic acid. As oceans become more acidic, small animals in the crucially important marine food chain are unable to form their calcium carbonate shells. Oregon and Washington oyster growers discovered this in the mid-2000s when their “larvae” were unable to develop into the “seed” needed re-populate their oyster beds. Upwelling ocean currents carrying 50 year-old concentrations of carbon dioxide were mixing with CO2-rich surface water to create pH levels too acidic for the larvae to survive. The oyster growers have temporarily solved the problem by importing larvae from elsewhere.

7. During a tweet connection from the International Space Station to a school in Bedford, Nova Scotia, a student asked the new commander of the ISS, Canadian Chris Hadfield, if any signs of global warming were visible from space. Hadfield quickly replied that evaporated lakes, shrinking glaciers and desertification were all clearly evident (CBC Radio, Jan. 5/13).

8. In CBC Radio’s popular science program, Quirks and Quarks, listeners were invited to predict the future, and then experts were asked to respond (Jan. 5/13). One prediction was that by 2075, 50 percent of Canada’s boreal forests would be burned by forest fires. The expert disagreed — he said the amount would probably be in excess of 55 percent. In the 1970s, he said, the loss to fires was about 1 million hectares per year (m/ha/yr). Today it is about 2 m/ha/yr. By 2075 it will be at least 4 m/ha/yr. A rise of 3-4°C in boreal temperatures by 2075 will mean that forest fires will become larger and more common, making human habitation more risky — the 2011 forest fire that raged through the Alberta town of Slave Lake destroyed half its buildings and caused $750 million in damage. A precipitation increase of 40 percent would be needed to compensate for the warmer conditions. Many burned areas will naturally re-seed but, if fire cycles are more frequent than every 20 years, boreal forests will revert to grassland rather than regenerate.

9. Arctic ice melt reached record levels in September, 2012.

10. The US National Oceanic and Atmospheric Administration announced in October, 2012, that the previous month had been the warmest September on record, tying the 2005 title (Globe and Mail, Oct. 17/12). Using temperature records that stretch all the way back to 1880, September, 2012, “marked the 331st straight month with above average temperatures, and the 36th straight September with global temperatures above the 20th century average.” This means that “the last below-average month for any month of the year occurred in February 1985”, and that everyone who is 27 years-old or younger has never lived in a cooler than average month.

In praise of Science and Reason

I’ve never been a member of a political party, although I did consider joining the NDP earlier this year, just so I could vote for Nathan Cullen in the leadership contest. Now I’m considering joining the Liberals, just so I can vote for Joyce Murray.

In the rarified air of Parliament Hill, where so many Opposition MPs seem to exist in an alternative reality, these two brave souls have pointed out what any sane Canadian can already see: if we want to escape from Harperland and return to something resembling the Canada most of us know and love, the NDP, the Liberals and the Greens are going to have to co-operate and run candidates strategically in the next federal election.

It is (perhaps) interesting that both these MPs are from the invisible province of British Columbia. I say “invisible” because, in the current debate about the East/West divide, it seems to have escaped the notice of many eastern commentators that there is an entire province to the west of Alberta which, by and large, does not share its eastern neighbour’s rapacious, laissez faire attitude towards the environment.

I can remember a time when American backpackers wore Canadian flag pins to make their appearance in many countries less unwelcome. Other than Israel (where our Foreign Minister’s shamefully vitriolic rejection of the Palestinian people’s statehood aspirations were very welcome indeed), I’m not sure how helpful a maple leaf is these days.

I hate feeling embarrassed about being a Canadian. And on an almost daily basis the number of reasons for embarrassment grows. No sooner had the Harper Tories rejected efforts to supply cheaper generic drugs to desperate countries, then our International Co-operation Minister was boasting about how useful the Canadian International Development Agency (CIDA) can and should be to Canadian mining companies and other corporations. (Anyone wondering why this is a very bad idea should read Samantha Nutt’s excellent book Damned Nations.)

If I had to pick one reason – and it isn’t easy – it would be the Harper government’s flagrant disdain for science (which, for the Prime Minister and his oil sands cronies, really is an inconvenient truth).

Denying the existence and dire consequences of manmade climate change would almost be less embarrassing than paying lip service to both, then tossing its Kyoto protocol obligation to reduce greenhouse gas emissions out the window, as this government has done. Then there’s the embarrassment of watching the Harper contingent swanning around this month’s climate change negotiations in Doha attempting to stymie any meaningful action by others. When pundits conclude that Canada could learn from the US on emissions reduction, you know you’re in serious trouble.

Meanwhile, back in Ottawa, following a limited debate, the number of rivers and lakes protected by the Navigable Waters Act was reduced this month from more than 2.5 million to 159.

Protection of Canada’s ocean ecosystems had already been tossed out the window with the decision by the Harper government that the primary remit of the Department of Fisheries and Oceans should be boosting fish farms. This “trade uber alles” mandate was threatened last year when the Cohen enquiry heard from Fred Kibenge of the Atlantic Veterinary College in Prince Edward Island that Infectious Salmon Anaemia virus had been found in samples of BC salmon. Kibenge predicted that he would be attacked by the government and he was right.

Unfortunately, attacking independent scientists, gagging or simply firing vexatious government scientists and gutting existing environmental legislation is not enough for this government.  As Dr Darryl Luscombe warns in a recent Watershed Sentinel article, a primary goal of the controversial Bill C-38 is to curb the participation of an informed public in environmental reviews of contentious projects.

Neil deGrasse Tyson once said: “To be scientifically literate is to empower yourself to know when someone else is full of bullshit.” Sadly, scientific literacy does not help when your government legislates against it.

And so I appeal to the Liberals and the NDP and the Bloc and the Greens: For the sake of Archimedes and Galileo and Darwin (and all of Canada’s dedicated and currently harassed government and independent scientists), please put partisanship aside and bring back informed, civilised debate.
