    IPCC report shows action on climate change is critical

    October 3, 2013

    The Intergovernmental Panel on Climate Change just released the first of four chapters of its Fifth Assessment Report. It shows scientists are more certain now than in 2007 when the Fourth Assessment was released that humans are largely responsible for global warming — mainly by burning fossil fuels and cutting down forests — and that it's getting worse and poses a serious threat to humanity.

    Resolving the problem of climate change will cost, but it will be much more expensive to follow the defeatist advice of industry shills, whose greed and lack of care for humanity will condemn our children and grandchildren to an uncertain future. More »

    From Arctic tundra to primeval rainforest to arid desert, our natural world is being fragmented by ever-expanding towns and cities, roads, transmission lines and pipelines, and pockmarked by mines, pump jacks, flare stacks and other infrastructure used to drill, frack and strip-mine fossil fuels.

    Many urban areas have built or are considering building waste-incineration facilities to generate energy. At first glance, it seems like a win-win. You get rid of "garbage" and acquire a new energy source with fuel that's almost free. But it's a problematic solution, and a complicated issue. More »

    The science is clear: human-caused climate change is the most pressing threat to humanity, and we must work to resolve it. We don't have time for debunked conspiracy theories. More »

    Beaver Lake Cree case reveals flaws in environmental review process

    August 29, 2013

    The Beaver Lake Cree Nation court case makes us look at the impact of development in a cumulative, holistic way. As BCLN lawyer Jack Woodward said, the case "is based on protection of the entire ecosystem." If we don't take that perspective, our hacking away with small cuts will destroy the underpinnings of the whole system. More »

    Is geoengineering a silver bullet for climate change?

    Rather than rationalizing our continued use of fossil fuels in the false belief that technology will enable us to carry on with our destructive ways, we really need governments, scientists and industry to start taking climate change and greenhouse gas emissions seriously. More »

    We focus on charismatic species like whales, pandas, cedar trees and seals as poster children for conservation. But the small things that keep the biosphere going for creatures like us are probably more threatened because we ignore them. If we spend time studying them, they have much to teach us. More »

    Smoking trends in countries like Canada show that societal change is possible and — with education and regulation — people will do what's best for themselves and for the world around them. More »

    We need to get a handle on the toxic chemicals we use to grow food. If our practices kill insects and birds that make it possible to grow crops, we're defeating their purpose and putting ourselves and the rest of nature at risk. More »
