$6 cooker to save the world

| 13/04/2009

(Discover Magazine): The Kyoto Box, a $6 solar cooker made from cardboard, has won the Financial Times-sponsored Climate Change Challenge contest for innovative ways to decrease the human impact on the environment. Its capacity to not only cook food but also sterilize water could help three billion people reduce their greenhouse gas emissions. The Kenya-based Norwegian creator of the cooker, Jon Bøhmer, has been awarded $75,000 to put the idea into production.

    This guy is much more eloquent than most….and he is from auz, where they know about what it is like on the curve of climate change…

    Poor prognosis for our planet

    Every patient with an incurable illness will ask how long they have to live. The answer goes something like this: “No one can say how long you may live, because every individual is different, but focus on the changes you observe and be guided by those. When things start changing for the worse, expect these changes to accelerate. So the changes that have occurred over a year may advance by the same degree in a few months, then in weeks. And that is how you can judge when the end is coming.”

    Apply that thinking to climate change. When An Inconvenient Truth opened in 2006 it was generally supposed we had a window of two or three decades to deal with climate change. Last year that shrank to a decade. Last month Australia’s chief scientist, Penny Sackett, told a Canberra gathering that we have six years to radically lower emissions, or face calamitous, unstoppable global warming.

    Six years. Given that this problem is usually described as a process unfolding over centuries, how can it be that things have spun out of control in such a short time?

    Climate change is often described as linear decline followed by some kind of distant “tipping point”. But consider these statistics: in 1979 Arctic sea ice cover remained above 7 million square kilometres all summer; from 1989 it was consistently above 6 million; in 2002 above 5 million; since 2007 above 4 million. I read recently we may have reached a tipping point and the ice will be gone in 20 years. But there is no tipping point – a curve is always tipping, and each new finding redraws the curve.

    If this year’s figure comes in under 4 million square kilometres the patient could be dead inside five years, and ships will be crossing the North Pole in September 2014.

    I do believe the evidence. Which leads me, personally, to the bleak conclusion that the human race is stuffed. The current financial crisis is merely the curtain raiser to a grand opera of social and ecological collapse. Our children – forget our grandchildren, I’m talking about my own kids, aged 14, 11 and 9 – are going to live in a world in which major cities are flooded, fertile plains become deserts, populations run out of food and water, rivers run dry, fishing grounds become dead zones, our rainforests and living coral reefs become curiosities of history.
    ….
    Of course, there is a great problem with declaring that point of view because one immediately becomes labelled as a mad Cassandra spouting visions of the apocalypse.

    The parlous state of our planet’s health could not be more evident, and still nothing has happened, except that eminent scientists like Jim Hansen have been driven to join the barricades. Demonstrating last month in Britain for a complete moratorium on new coal-fired power stations he said with typical understatement: “The democratic process doesn’t quite seem to be working.”

    We would rather watch TV shows glorifying some brainless criminal underclass than engage in meaningful civil disobedience. Since Greenpeace went corporate there has been a global shortage of eco-warriors, and most scientists lack the mongrel element to start a revolution.

    The rest of us are less evolved; my suspicion is that most of us still don’t get it. Because here’s the paradox: wherever you look in the natural world the message of exponential change is reinforced, yet humans have a weird predisposition to see change as linear. I’m guessing this is a throwback to the caveman days when, if someone threw a rock or a spear at you, itwas sensible to assume that the missile would keep coming at a constant speed. Strangely, we unconsciously apply the same neanderthal logic to our understanding of ageing, birth and climate change.
