(1) Comments | Posted April 25, 2017 | 1:35 PM

Years ago, I remember listening to a radio documentary that reconstructed the dramatic final moments in the control room of the Chernobyl nuclear power plant in Kiev, Ukraine on April 26, 1986. That re-enactment came to mind recently as I read two news stories: one about accelerating warming of our...

The Arts Make A Surprising Ally In Raising Climate Awareness

(0) Comments | Posted November 25, 2016 | 11:43 AM

When I was in school, my favourite subjects were math and the sciences -- fields well suited to a personality that thrived on facts, data and certainty.

My least favourite subjects were humanities and the arts. They introduced vagueness, interpretation and other uncomfortable notions that challenged my neat black-and-white views...

Canadians Must Rethink 'Normal' To Tackle Climate Change

(0) Comments | Posted October 14, 2016 | 1:45 PM

For most of us, yesterday was probably a pretty normal day.

We woke up, showered and had breakfast. We hopped into a car and headed to work. We did whatever it is we usually do all day, then returned home for supper. We taxied kids, relaxed for a bit...

TransCanada Silence On Climate Speaks Volumes In Pipeline Debate

(26) Comments | Posted July 8, 2016 | 11:46 AM

"It is difficult to get a man to understand something when his salary depends upon his not understanding it," American author Upton Sinclair wrote in 1935.

If a recent email exchange I had with TransCanada Corporation, the proponent of the Energy East Pipeline, is any indication, Sinclair's declaration...

10 Years Later: Some Inconvenient (And Convenient) Truths

Last week marked the 10th anniversary of An Inconvenient Truth, the Al Gore documentary that catapulted climate change onto the global agenda.

Here's a quick look at developments over the past decade, both the inconvenient and the convenient.


Unfortunately, global consumption of fossil fuels -- oil, coal and natural...

A Lesson For Today From My Least Favourite Class In High School

(0) Comments | Posted April 6, 2016 | 5:22 PM

When I was in high school, my least favourite class was English. It wasn't my teacher's fault; it was just that, somehow, the lessons of ancient literature did not resonate with my teenage mind. But thanks to the passage of time and a few "aha" moments, I've come to appreciate...

Canadians Can Stop Being The World's Worst Waste Generators

(0) Comments | Posted February 12, 2016 | 11:32 AM

Two very different stories about garbage showed up in my news feed recently -- presenting starkly different pictures of the trash habits of Canadians.

Record trash
"Canadians piling up more garbage than ever" read the first headline.

The story beneath it was that Canadian households generated seven...

These days, I'm finding myself torn between climate change hope and climate change unease. I know the first can win out and the challenges we face can be solved, but this month is an especially critical one. Here's why.

On November 30, representatives of over 200 nations will...

While Worried About The Election, We Forgot About World Food Day

(9) Comments | Posted October 30, 2015 | 3:38 PM

With all attention in this country focused on Oct. 19, another date -- arguably even more important --slipped by us earlier this month.

Oct. 16 was World Food Day. The fact that it passed entirely without notice reaffirms just how lucky we are to live in this blessed...

Think Climate Action When You Vote

(7) Comments | Posted October 14, 2015 | 5:53 PM

Climate change ought to be a major issue this election, but I'm saddened to note that it has received little attention. Perhaps a quick update on both the problem and the solutions would add some helpful perspective in these final days of the campaign.

Every day, I Discover a New Reason to Vote out Harper

(121) Comments | Posted October 2, 2015 | 12:34 PM

When new Canadian leaders are elected, I try to keep an open mind and give them a chance before passing judgement. It seems to me that's the Canadian way.

Stephen Harper was no exception: in 2006, I actually looked forward to seeing where he would lead our country.

But before...

Canada Must Put a Price on Carbon Emissions

Whenever I meet a Hummer, tension rises in my chest, unkind thoughts develop in my head and my hands tighten and tremble, as if they want to signal something.

I've long wondered why that happens, and I think I've finally figured it out. It has something to do with...

Our Sense of Entitlement Could Be the Biggest Barrier To Solving Climate Change

(8) Comments | Posted April 21, 2015 | 6:13 PM

Every now and then, when I pause to ponder the biggest barriers to fixing the many environmental challenges we face, there's one troubling word that keeps coming to mind. It's not "technology," "money" or even "Exxon."

The word is "entitlement." Could this be the unflattering descriptor that will define...

Our Carbon Quota Is Shrinking All the Time

Perhaps you've heard of the notion of a global carbon quota. I first learned of it a few years ago, and got a refresher on the subject last month. It jolted me then, but even more so this time. Here's an overview, with some basic math.

An Imminent Climate Change That Has Nothing to Do With Greenhouse Gasses

I have an announcement to make: Canada's climate is about to change dramatically. It will get warm, the snow and ice will disappear and vegetation will emerge and flourish. And it has nothing to do with greenhouse gases.

You see, spring arrives next month. Sorry if that sounds anticlimactic, but...

Buying Less Stuff Can Actually Make You More Happy

Tax time is never pretty, and for me last year was uglier than usual. By the measures of economics and Revenue Canada, I didn't have a great 2013. But by the measures of sustainability and fulfillment, I had an awesome 2013. How could that be?

Coincidentally, a book I...

The Human Side of Climate Scientists

(1) Comments | Posted November 13, 2014 | 4:56 PM

Science is a profession of discipline and process. Scientists live in a world of constant questioning: they observe, analyze, theorize and test, and then do it all over again. Guided by facts and data, they strive to drill through uncertainty and draw solid, evidence-based conclusions.

That's why a blog I...
