False debate: A mosaic celebrating the scientific consensus on climate change

Scientists overwhelmingly agree that climate change is happening and that it is caused by humans. In the words of the latest IPCC report: “Human influence on the climate system is clear, and recent anthropogenic emissions of greenhouse gases are the highest in history.” And yet people still seem to think there’s a debate about whether or not climate change is (a) occurring and (b) caused by human activity. This manufactured debate is courtesy of a handful of powerful corporations whose wealth is inextricably tied to the fossil fuel industry and who are able to exert a disproportionate amount of influence on the media and politicians. The result is public confusion. This whole situation frustrates me to no end. By all means, let’s debate. But let’s not debate about whether or not climate change is happening. (Spoiler alert: It is.) Instead, let’s talk about what we should do about it, which policy instruments we should employ. Now there’s a debate I’d welcome with open arms (as long as it actually leads to action).

climate consensus pie chartThis so-called ‘debate’ about climate change is what inspired this mosaic. A 2013 study by John Cook of The Consensus Project examined a whopping 12,000 peer-reviewed journal articles about climate change published between 1991 and 2011. Of the roughly 4,000 that stated a position on anthropogenic climate change, 97% of these articles endorsed the scientific consensus that humans are causing climate change. The rest? Well, that’s just junk science. (You can watch Cook explain his study in this 3-minute video.) Even with the scientific consensus sitting around 97% and growing, public perception of scientific agreement is far lower (people believe that about 50% of scientists support anthropogenic climate change). And this ‘consensus gap’ between scientific reality and public perception prevents us from taking meaningful action to address climate change as we go around in circles, debating something that has actually been settled for years.

And so I decided to turn this convincing pie graph into a mosaic. The outlying 3%—the junk science—is quite fittingly represented by a bunch of rusty bits of metal (scavenged a year ago on the streets of Ottawa during the spring thaw) and coal sent to me by one of my Touchstone classmates. It’s funny, I very nearly got the math wrong on this when I was sketching it out. For some reason, my brain hopped instantly from 3% to 3º. Luckily, just before I was about to start sticking stuff down, I realized 3% is actually closer to 11º. Glad I caught that one!

This piece is so full of different materials that I had a hard time coming up with a list! There are stones, of course: shale, limestone, sandstone, coal, and Eramosa marble (and probably others that I can’t identify). There are two roundish red rocks I picked up along the banks of the St. Lawrence while out for a sunny Thanksgiving stroll. There are concretions given to me by friends in Alberta and Pennsylvania. There’s cement parging fallen from various walls around my neighbourhood—always in ample supply in the spring. There’s a variety of floor tiles (some even salvaged from my parents’ recent renovation, which my feet and my family’s feet have walked over a thousand times), brick that the Ottawa winter kindly liberated from a neighbouring house, and one of my favourite plates from my university days. And there is Italian smalti and hints of vintage 24-karat gold smalti (a splurge when I was in Chicago).

I had a heck of a time naming this piece. When I originally conceived of it, I got used to just referring to it as my “Junk Science” piece. I liked the ring of it and I was very close to actually naming it that. But then it struck me: why should the 3% minority get naming rights? Unacceptable. And so, “Quod erat demonstrandum (All else is junk science)” was born. The title comes from the only thing I managed to retain from the two weeks I spent in high school Algebra and Geometry before dropping the class (let’s just say that word problems are not my strength); QED is what you put at the end of a mathematical proof to indicate that it is complete (it roughly translates as “that which was to be demonstrated”). I guess it’s kind of the mathematical equivalent to dropping the mic? Anyway, I like how it lends a certain seriousness / formality to the piece, which is appropriate given that we’re really talking about one of the most fundamental concepts that I will ever deal with in this series.

As a final note, I wanted to mention that I’m really excited about this piece and how it turned out. There’s something about it that feels different, like something in me has shifted in some way (though I’m still working on putting my finger on what, exactly, that is and harnessing it going forward). I have a feeling that this mosaic will be an important marker in my evolution and growth as an artist, and this has me grinning a big ol’ stupid grin!

Bonus video: If you like sensible and funny commentary, you’ll love this John Oliver segment on the climate change ‘debate’. It is so perfectly bang on.

    I have been following your blog for a while. Not sure how I found your blog but probably as a result of both of us taking a class from Rachel Sagar. I have to tell you that not only do I love your beautiful mosacis but your writing is skillful and adds to the enjoyment of your mosaics. The way you use line and color to tell your story is absolutely beautiful. I have learned from your positive attitude, willingness to talk about your process, and the mosaics you have posted and discussed. Thank you so much for sharing your mosaics through your blog and website. This new piece tells an important story and I think it is a culmination of all your skills coming together into one serious and wonderful piece of art! Danette

      Oh Danette, thank you for such a lovely comment. You essentially summed up all the reasons I blog, so I’m just thrilled that there are people out there who are “getting” it. Thank you!
