Facebook Is Not Our Friend

I wrote a blog entry over four years ago about Facebook tolerating hate groups. I won't repeat the post here, other than to say it became apparent after I lodged a complaint with them and got a wholly unsatisfactory reply that the company must have a very strange set of community standards, given that I was told the anti-Muslim group in question did not violate them.

It now appears that the situation at Facebook is even worse, thanks to its promotion of private and 'secret' groups, some of which have very frightening agendas. The following Global News reports explains all:



Facebook is a corporate digital giant that needs far greater government intervention and regulation than has thus far been meted out. Despite its public persona, it is clearly not our friend.

Look To The Skies

Only a simpleton would deny the reality of climate change. Whether we are reading almost daily about wildfires, tornadoes, floods or sea-level rise, we know in our hearts that the future has arrived and will only get worse. Despite that understanding, many of us continue with practices that will only aggravate the problem.

One of the most egregious is flying, something I continue to be guilty of, usually twice a year. Since people are not inclined to stop visiting loved ones who live far away, or taking that much-needed winter getaway, are we doomed then to simply add to the greenhouse gas emissions that are fueling climate change?

Gwynne Dyer offers his perspective both on the scope of the problem and a possible partial answer to it through new technology:

Aviation accounts for around 2.5 per cent of human-caused greenhouse gas emissions at the moment, but the contrails the planes leave in the stratosphere turn into cirrus clouds that reflect heat back to the surface, and that causes an equal amount of heating.

So in reality five per cent of current warming is already due to aviation, and industry representatives estimate that the number of people flying annually will almost double (to 8.2 billion) in the next 20 years. By then flying will have grown to 10 per cent of the global heating problem, or even more if we have made good progress on cutting our other emissions.

Should we despair? Dyer suggests there are solutions that don't entail an outright stop to flying, but they are ones that the aviation industry has shown little interest in, corporate inertia being what it is.

A number of people have been working on DAC (Direct Air Capture of carbon dioxide) for more than a decade already, and the leader in the field, David Keith’s Carbon Engineering, has had a pilot plant running in British Columbia for the past three years.

Keith’s business model involves combining his captured carbon dioxide with hydrogen (produced from water by electrolysis). The electricity for both processes comes from solar power, and the final product is a high-octane fuel suitable for use in aircraft.

It emits carbon dioxide when you burn it, of course, but it’s the same carbon dioxide you extracted from the air at the start. The fuel is carbon-neutral. Scaling production up would take a long time and cost a lot, but it would also bring the price down to a commercially viable level.

The problem with the heat-reflection caused by contrails also has some mitigation-avenues available:

The planes are flying so high for two reasons. The air is less dense up there, so you don’t use so much fuel pushing through it. But the main reason, especially for passenger planes, is that there is much less turbulence in the stratosphere than in the lower atmosphere. If the planes flew down there, they’d be bouncing around half the time, and everybody’s sick-bag would be on their knee.

So what can you do about it? Well, contrails only form in air masses with high humidity, and therefore only affect 10 to 20 per cent of flights. With adequate information, most of those flights could simply fly around them. Alternatively, fly below 7,600 metres for that section of the flight, and contrails won’t form anyway.

It will be more turbulent down there, so in the long run we should be building aircraft that automatically damp out most of the turbulence. This is probably best achieved by ducted flows of air that instantly counter any sudden changes of altitude or attitude, but if aircraft designers started incorporating such ducts into their designs today, they’d only come into regular use in about 15 years’ time.

One should always be wary of deus ex machina solutions. However, the approach suggested by Dyer surely deserves consideration as one of the strategies needed as the climate crisis continues to worsen.

Time For Reflection

While the battle for climate-change mitigation will be won or lost by regulating the big polluters, it is all too easy for us to scrutinize them to the exclusion of our own profligate greenhouse-gas-emission practices. The following letter in the print edition of today's Toronto Star should give us all pause:

We in Ontario should try for numerous gestures of reconciliation with our western neighbours.

I agree with Jason Kenney that programs for reduction of carbon emissions should focus on consumers, perhaps more than on producers. I’m a consumer.

The oil companies will continue to develop their resources as long as it is a profitable enterprise.

When we as consumers reduce our demands, oil production will be reduced accordingly. The transportation industry is the biggest contributor to carbon emissions: Long distance trucking and air cargo are filling the atmosphere with carbon, because we want our wine and beer from Europe and Australia, our clothing from Asia, our cars and computers from Japan and China, our asparagus from Peru, our fruit from California, etc.

Buy local wine, even if you think it’s not as good; buy local craft beer.

Try to buy food from the nearest possible sources, though, admittedly, in winter that’s not easy. I believe we should trade in our cars with big engines and go hybrid (better range than all-electric), even if it’s more expensive and less convenient.

Reduce long-range travel by car or plane; use transit, or car pool to work if at all possible. Think of using electricity to heat your home, even if it’s more expensive, because it’s cleaner.

Recalibrating the energy industry toward cleaner technology and alternative sources of energy will provide major employment opportunities in Alberta and everywhere. It will cause wrenching grief for some, just as the prohibition of fishing for cod caused grief for workers in Atlantic Canada some years ago.

Fighting the oil producers will only cause resentment. Everyone has to make major lifestyle changes. We have to start with ourselves.

Tis Devoutly To Be Wished

Now This News asks a question:

What If Fox News Covered Trump the Way It Covered Obama?

As The Dust Settles....

I will offer no analysis of our federal election; I will only say that from my perspective (my disappointment that the Greens did not do better notwithstanding), the fact of a minority government is the best of all outcomes. The question of whether or not Justin can find within himself the capacity to play nice with others is yet to be determined, but for the sake of the country, we can only hope he does.

While many pressing issues stand to be addressed, pharmacare being uppermost in Jagmeet Singh's mind, I do hope that effective action to address climate change will also be on the agenda. This latest report reminds us that we have little time to lose:

Research has found Arctic soil has warmed to the point where it releases more carbon in winter than northern plants can absorb during the summer.

The finding means the extensive belt of tundra around the globe — a vast reserve of carbon that dwarfs what's held in the atmosphere — is becoming a source of greenhouse gas emissions responsible for climate change.

The research by scientists in 12 countries and from dozens of institutions is the latest warning that northern natural systems that once reliably kept carbon out of the atmosphere are starting to release it.

While this is only one of several feedback loops exacerbating climate change, it is a potent one.

The scientists placed carbon dioxide monitors along the ground at more than 100 sites around the circumpolar Arctic to see what was actually happening and took more than 1,000 measurements.

They found much more carbon was being released than previously thought. The results found carbon dioxide emissions of 1.7 billion tonnes a year are about twice as high as previous estimates.

Arctic plants are thought to take in just over one billion tonnes of the gas from the atmosphere every year during growing season. The net result is that Arctic soil around the globe is probably already releasing more than 600 million tonnes of CO2 annually.

And the process is accelerating.

Under a business-as-usual scenario, emissions from northern soil would be likely to release 41 per cent more carbon by the end of the century.

But the Arctic is already warming at three times the pace of the rest of the globe. Even if significant mitigation efforts are made, those emissions will increase by 17 per cent, said the report.

Our house is on fire. Only resolute, principled politics holds any hope of containing the conflagration.

The Best Way To Effect Change

H/t Michael De Adder

Should you need further encouragement, read the columns by Martin Regg Cohn and Susan Delacourt.

Says Cohn:

Decide for yourself who to vote for but whatever your decision, do not persuade yourself that your vote doesn’t matter. Nothing is more corrosive than cynicism at a time when so many citizens around the world crave the certainty and stability of our democracy.

Think of the citizens of Hong Kong who are protesting in the streets for a semblance of democratic rule that Canadians take for granted. Consider the people in the Middle East who dreamed of an Arab Spring, only to see it fade away. I lived in both places for a decade, covering the human rights movements where people risked bullets for ballots, and were prepared to die for democracy, then as now.

And, from my perspective, most importantly,

Even in so-called “safe seats” that seem predestined to favour the incumbent MP, every ballot contributes to the national popular vote tallies that are very much taken into consideration, historically, by a governor general in deciding which party (or combination of parties) has a mandate to govern.

As well, Susan Delacourt reminds us,

There is a point, though, in taking the time to vote, especially at this juncture in history. Look to the U.S. or Britain and the turmoil in politics there over the past few years. Democracy matters. Elections matter. Voting matters.

... I’m hoping that 2015 wasn’t a blip — that the upward trajectory in turnout continues on Monday, because we’re seeing how fragile democracy can be, even in nations with deep, democratic traditions, such as the U.S and Britain.

There are many ways to honour our citizenship. Participation in the voting process is one of the best.
