Today is Blog Action Day ‘09, and this year’s topic is climate change. What better topic for an ecoBlogsphere Watch post? Most of these links come from the last 3 months or so.

Let’s be clear. This isn’t about politics; it’s about facts. Ice doesn’t care how you vote or what you believe, it will melt regardless, as long as it’s above 0 degrees Celsius. Fact: at the current rate of melting versus snowfall, Glacier National Park (USA) will have no glaciers left by 2020. The glaciers of North America’s interior mountains are melting at an astonishing rate (I highly recommend taking the walk to the edge of the Athabasca Glacier to get a sense of how fast it’s happening). This should be a huge concern to citizens of cities like ours that rely on rivers whose source is those glaciers. How will our communities change when glaciers no longer feed those rivers?  Fact: the Arctic pack ice is also disappearing, with the last three summers marking the three lowest extents of Arctic sea ice since 1979, and totally ice-free summer conditions now expected within 20-30 years. And a must-read report on prehistoric carbon dioxide levels using ocean floor sediment samples in this week’s issue of Science may explain why that is happening way faster than previously predicted, and indicates that our current political targets for emissions reduction are probably not stringent enough.

The consequences of climate change will be felt everywhere, in ways we don’t yet appreciate as a society: people are aware that the extinctions of large numbers of vulnerable species is one cost of inaction (save the polar bears!), but tend to think less about human problems like floods, droughts, famines, wars, and refugee migration. Google have used their Maps app to create stunning visuals of how different our planet could look with conservative estimates of temperature changes worldwide and flooding in coastal regions – go watch if you haven’t seen it yet.  The military are already using these when-not-if scenarios as part of their strategic planning, and so are the agribusinesses who’ve led the rush to buy fertile land in Africa, Asia, Eastern Europe, and Latin America.

What can we do? I mean, apart from becoming survivalists living on off-the-grid communes on high ground – good luck to you if that floats your boat, but personally, I like city living.

Well, we can mitigate these consequences by reducing our greenhouse gas emissions and slowing down the rate of global climate change. (We’ve made a change that big before: think of the 1980s ban on chlorofluorocarbons to save the ozone layer. And most experts agree that we have the tools and technologies we need – see TED.com and worldchanging.org – we just need the political will to apply them.) This means asking the Canadian and Albertan governments to kindly stop cowtowing to the interests of multinational businesses (many of whom are already quietly investing in biofuels and renewables), to sign treaties and adhere to them, to create provincial building codes and municipal guidelines that value density and energy efficiency, to work to integrate renewable energy generation as a major component of the grid, and to create programmes to retrain workers and retool industries. Well-drillers can become geothermal experts, and machinists and electricians can learn how to build and install solar and wind microgenerators.

On an individual level, this means becoming engaged citizens, asking tough questions of our representatives (especially here in Oil Country), and making appropriate choices for our families. It means looking hard at our homes and habits, then making honest efforts to do what we can to reduce our environmental impact. Locally, lots of organizations are working to help us do these things – signing up for E-SAGE’s newsletter is a great way to keep abreast of all those groups’ events and projects.

After figuring out what our homes’ and businesses’ carbon footprint is and doing what we can to make it smaller, the best (although still flawed) way to mitigate the effects of our remaining emissions is still to buy carbon offsets – thankfully the David Suzuki Foundation has recently created an independent report on offsets that helps us navigate that minefield and figure out which offsets do the most good.

Am I a total nag? Good. In graduate school, we scientists are taught to use language carefully, to always provide context and not jump to unwarranted conclusions. You don’t ever want to appear alarmist or unprofessional. It’s very difficult training to break. So when I read the statements being made by climatologists, ecologists, and wildlife biologists about climate change and its consequences, I’m startled by their urgency and directness.

We’ve already unwittingly changed the world. Now it’s time to change our course.

Has anyone else been sick for most of the winter? We’ve had the flu run through our home twice. (But I still strongly believe in vaccination. Sorry, Jenny McCarthy.) This means I’ve been a slacker about blogging, and meanwhile, the world has kept turning. Let’s catch up with it, shall we?

New Year’s always means decor trend predictions. My predictions? People are hungry for meaning and security as we navigate the most turbulent economy in 80 years, and this means we’ll want our homes to reflect our deepest values. We’ll still be eager for style and beauty, but less impressed by fashion, and our luxuries will be smaller, more sentimental, more likely to be handmade. “Democratic decorating”, supporting emerging designers on Etsy (like Keith Moore’s bamboo clocks – mmmmm) and at local craft fairs, idiosyncratic mixing of styles and periods, and choosing the most Earth-friendly products will be as important as ever. We’ll still want our homes to be serene, abundant havens, and as a reaction to consumerism, many people will want to declutter and simplify.

Sadly, Domino magazine is no longer here to champion that vision of modern, eclectic, sustainable design; legions of decor bloggers are carrying that torch now.

I’ve been waiting to write about this story for months now. As reported on pages 40-41 of Green Living Online’s Fall 2008 edition, Canada’s Building Codes get only failing-to-poor grades on energy efficiency and sustainability issues, with Alberta failing with the second-lowest grade at 42% (after Nunavut at 40%). No province scored higher than a C. The report itself has not been released by Environmental Defence Canada to date, and I wonder now if it will be. Since it was drafted, parliament has been prorogued and reassembled, Obama has taken office as President, the North American economy has gone from having foreclosure jitters to a full-blown recession, and Environmental Defence appear to have concentrated their resources on the Alberta’s Tar/Oilsands and bisphenol A stories. Meanwhile, this page linking to their May 2008 Green Building Benchmarks seems to be the one to watch for further news on this front: http://environmentaldefence.ca/greencodes/index.php

Alberta’s building codes may not be green enough, but local business in Edmonton is getting greener all the time. The past couple of months have seen local mainstream media coverage of local & organic foodies d’Lish, green home decor & gift destination Carbon Environmental Boutique, and brand new eco-spa/salon The Beauty Parlour. The inexhaustible Jessie Radies (of Keep Edmonton Original and the Blue Pear) is starting to organize a local organic food co-op. E-SAGE hosted a series of fascinating talks by local economies expert Michael H. Shuman, available for download on their website, and are creating a sustainable business directory.

We’ve also seen prominent coverage of the CMHC’s NetZero demonstration homes, though unfortunately CBC emphasized how unaffordable green building is, instead of contextualizing net-zero as being part of a broad continuum of options. As inspiring as the NetZero homes and this LEED-Platinum reno of a 1915 Craftsman bungalow are, you don’t need to go to that extreme to make your home greener. But you knew that, right?

Reports of Compact Fluorescent Lamps causing migraines and skin rashes got a wide airing in late January. I’m still recommending them, for all the reasons I always did, plus one more: I’m skeptical of these claims. The idea that compact fluorescents cause migraines dates from the days before manufacturers switched to electronic ballasts for them, when once in a while you’d find one that flickered a bit – and the well-documented problem of the flickering of their non-compact relatives acting as a migraine trigger in some susceptible individuals. Newer bulbs don’t flicker. As for the skin rashes, it seems unlikely that they are UV burns as claimed, since the spirals are made of UV-blocking glass – and the bulbs I prefer (Philips Marathon in Soft White, and Ikea’s, which both have excellent colour rendition) have the spirals enclosed in frosted Edison-style glass bulbs to diffuse the light. I’m glad that it’s being investigated, though — it’ll be easier to discuss this once we have actual data instead of just anecdotes.

Furthermore, the UK recommendation now is to stay more than 30 cm from bare CFLs. How many bulbs in your house are naked, instead of hidden behind a shade or a frosted Edison-style bulb? How many are 12 inches or less away from you? There aren’t any that answer that description in my home, and chances are there aren’t any in your home either, so there’s no need to panic and change them all back.

Besides, have you seen the new LED LACK pendant lamps at Ikea? In another five-to-ten years we’ll probably be able to replace our burnt-out CFLs with even-more-efficient LED bulbs and this whole discussion will become moot. These ones have the nicest LED light I’ve seen yet, without that extreme blue tinge you so often see. If only they were bright enough to provide task lighting.

While the press widely reported the CFL anecdotes, the ever-reliable-and-inspiring WorldChanging noted that US media almost completely ignored the latest climate science predictions regarding business-as-usual global warming. Of course, science reporting in general is abysmal, but ignorance of the newest climate data has criminal consequences:

“That means ultimate sea level rise of 250 feet, with the best current projection being 5 feet by 2100, rising thereafter 10 to 20 inches a decade (or more) for centuries.”

Wow. Nova Scotia becomes a chain of small islands, most of the world’s major cities are gradually (or not so gradually) swallowed by the ocean, economic & social implications enough to keep anyone awake at night. Maybe Jon Stewart should go after the media’s willful ignorance of climate science next?

Finally, the planting of an organic vegetable garden at the White House has everyone thinking about starting seeds and dreaming of spring: let me leave you with inspiration from a less famous Victory Garden.
