Ahead: More – and Worse – Katrinas

The science of climate change is the kind of topic that gives journalists great difficulty. As they bounce from issue to issue in our info-glutted world, they aren’t able to explore each one in depth or develop detailed expertise about a subject. So when it comes to complex scientific problems, journalists tend to cherry-pick findings and cite opinionated statement by outspoken researchers. Context and nuance are lost. And in the case of research on the links between global warming and hurricanes, context and nuance are everything.

Caught Up in Our Own Connections

But perhaps the most important factor contributing to our continuing vulnerability is something that we rarely recognize and that’s even harder to change: a belief that greater connectivity and speed in all aspects of society are always good things.

Coal in a Nice Shade of Green

When it comes to energy, we are trapped between a rock and several hard places. The world’s soaring demand for oil is pushing against the limits of production, lifting the price of crude nearly 90 percent in the last 18 months.

Out of the Energy Box

with S. Julio Friedmann | The prognosis for the future of climate change is indeed alarming. Scientists say plausible scenarios include terrible droughts, crop failures, and dying forests around the Mediterranean and in the United States, South America, India, China, and Africa. Sea levels are expected to rise significantly, drowning islands and possibly displacing hundreds of millions of people from coastlines, where more than a third of the world’s population lives. Ground water supplies are set to shrink, reservoirs to dry up. Wildfires and violent storms will strike more often and much harder. And much of this change is expected within the next 50 years.

Cold Truths About Global Warming

By February, Canadians’ love of fresh snow and winter sports has given way to annoyance, as we shovel our driveways for the umpteenth time. This winter, we’ve had some particularly nasty weather. But far colder and much nastier winters could be in store for us, especially for eastern Canadians and perhaps very soon. The culprit, weirdly enough, could be global warming.

Of Human Fallout

Remember the population bomb? This profound concern over exponential growth of the world’s population provided ample fodder for academic dispute and dinner conversation during the 1960s and 1970s. Commentators like Stanford University’s Paul Ehrlich warned we would soon see famine, eco-catastrophe, and war as poor nations failed to cope with their surging birth rates. Yet these worries were swept from the popular imagination in the 1990s, when a less gloomy view prevailed: Yes, world population had grown dramatically, but birth rates were dropping practically everywhere. Many conservative commentators declared that the human population explosion was over. The real problem had become the impending global “birth dearth” or “population implosion.”

The Matrix of Our Troubles

with Sarah Wolfe | One could draw a parallel between the sight of thousands walking north on Yonge Street and the mass exodus of people on foot from lower Manhattan two years ago. But yesterday’s electrical failure did not claim thousands of lives, nor will it trigger a cascade of events leading to war. Nevertheless, what we saw in Toronto was poignant for what it represented: a people too interlocked with their technical choices, too resolute on efficiency gains, and too dependent on progress. Last Thursday’s blackout should be a powerful catalyst for change.

Bringing Ingenuity to Energy

By /

Energy is our life-blood. Without an adequate supply at the right times and places, our economy and society would grind to a halt. Canadians are profligate users of energy: in fact, we have one of the highest per capita rates of consumption in the world. But if we were smarter about things, we would consume much less energy to support our current standard of living, and we would produce this energy with much less damage to our natural environment.

Response to Baliunas et al.

Complex issues like climate change are surrounded by a dense tangle of scientific theory and evidence that is difficult for any non-specialist to verify or understand. People can exploit this situation to tell very different stories about the issue. Because countless bits of evidence are available, it’s possible – by selecting and connecting the bits carefully – to construct practically any picture of the world and make it seem real.

An Open Letter to the Premier of Alberta

From Alberta’s point of view, the tar sands projects are, quite understandably, non-negotiable. But they immensely complicate our efforts to reduce Canada’s carbon dioxide emissions. There’s a way we can get out of this box, though: Alberta can become a world leader in two new technologies that are going to revolutionize humanity’s future energy production and consumption – underground carbon sequestration and hydrogen energy.
