Temperature’s rising: Embarking on a series devoted to climate change

I have just begun a new series dedicated to climate change. I won’t get into my motivations behind the series in this post, because I’m planning on doing a post exclusively on the ‘why’ of the series in the near future. Instead, this post will explore the first mosaic of the series.

It seemed like a no-brainer to start a climate change series with a mosaic based on rising global temperatures. The actual inspiration for this piece was the graph below, taken from the IPCC’s Fifth Assessment Report (essentially, a really really big report that contains the most up-to-date, reliable climate science available). I won’t get into the nitty gritty of the graph, but basically it shows that global temperatures are going up.

The verdict: It's getting warmer.

It actually took me quite a while to fiddle with my palette and figure out how exactly I wanted to execute the piece. The stones I used were from the Bruce Peninsula in Ontario (the white and red ones), Pennsylvania (the yellow stuff), and Kamouraska, Quebec (the thin jagged ones I used for the trend line). The yellowish sandstone has a lot of mica in it, which is fun to look at up close but ridiculously hard to photograph (at least with my meager photographic skills).

“Heat (Each decade hotter than the last)” (2014) — stone from Ontario, Quebec, and Pennsylvania, and a flue damper, 16.25″ x 24.25″

The metal circle in the bottom corner is a rusty old flue damper that I found in my daddy’s garage. I figured it was an appropriate sort of thing to include in this piece, since it’s used to control the air flow (and therefore temperature) in a wood-burning stove.

Daddy's garage is full of old treasures like this flue damper. I love that it's from Guelph, Ontario (close to where I grew up)

My favourite thing about this piece is the trend line. I love how the thin stones echo the annual variations shown in the graph, yet, when taken as a whole, clearly show an upward trend. These thin stones were actually a last-minute substitution. I had originally planned to do the trend line in terracotta (thinking the colour was appropriate for the subject matter), but there was something about it that just wasn’t sitting right with me. I’ve been learning the value of giving myself some distance when I’m unsure about something, so I let it percolate in the back of my head for a few days and eventually landed on the thin Quebec stones.

I am really excited about this series (I’ve already got ideas for at least 5 or 6 other pieces bouncing around in my head) and I’m looking forward to explaining my motivations in a future post. But for now, I hope you’ve enjoyed this little tour of “Heat (Each decade hotter than the last)”.

The sweet spot, diagrammed

I’m a huge fan of Jessica Hagy’s “Indexed” project, and this diagram of hers really struck a chord with me. Right now I’m at A. I want to shift to B. That’s the sweet spot.
