    Facts and evidence matter in confronting climate crisis

    March 23, 2017

    We recently highlighted the faulty logic of a pseudoscientific argument against addressing climate change: the proposition that because CO2 is necessary for plants, increasing emissions is good for the planet and the life it supports. Those who read, write or talk regularly about climate change and ecology are familiar with other anti-environmental arguments not coated with a scientific sheen. More »

    Intact wilderness is a hedge against our ignorance

    As we continue to alter the physical, chemical and biological properties of the planet by burning fossil fuels, intact nature is one of the only things that can save us. Pristine wilderness is a hedge against our collective ignorance. The diversity of our planet's ecosystems makes animals, including humans, resilient in the face of disruption. If protected, the Peel watershed would form the northern part of a proposed wildlife corridor that stretches all the way south to Yellowstone National Park in the U.S. It would be a refuge for wide-roaming species like caribou, moose, wolves and grizzlies to adjust their habitat needs as the planet warms.

    In this "post-truth" era, with a climate-change-denying U.S. administration, those who want to keep humanity wedded to outdated, polluting technologies have been emboldened. It's up to the rest of us to cut through the misinformation and help humanity get on track to a cleaner, healthier future. More »

    It's hard to fathom that so many people, especially in positions of power, can't see the many benefits of science and technological progress. It wouldn't be a battle if everyone accepted that clean air, fresh water, healthy agricultural soils and diverse ecosystems are critical to human health and survival. More »

    Marvelous monarchs move Minister McKenna

    February 23, 2017

    Federal Environment and Climate Change Minister Catherine McKenna had her mind blown recently. Remarkably, it had nothing to do with the political gong show south of the border. McKenna was visiting the hilltop monarch butterfly reserves in rural Mexico. There she saw millions of monarchs clinging to oyamel fir trees in mind-bogglingly dense clusters, surprisingly well-camouflaged for such colourful critters. She then wrote a heartfelt article calling on people in Canada to act before monarchs go the way of passenger pigeons and buffalo. More »

    Science is the most useful tool we have to adapt to climate change and avoid its worst outcomes. But it requires critical thinking and a big-picture perspective to ensure we consider all available evidence. With so many people scrolling through social media feeds for news rather than reading entire articles, facts and clarity can become elusive. It's up to us all — media and consumers alike — to dig deeper for the full story. More »

    We must enshrine nature as the source of our lives, livelihoods and happiness. Recent protests are about securing and protecting the most elemental needs of all people. Many Indigenous peoples are on the front lines, for everyone. I support them, with gratitude. More »

    Anthropocentric view ignores crucial connections

    For decades, scientists have warned that we're on a dangerous path. It stems from our delusion that endless growth in population, consumption and the economy is possible and is the very purpose of society. But endless growth is not feasible in a finite biosphere. Growth is not an end but a means. More »
