I have been traveling since the weekend and so I am behind on my reading. One of the benefits of writing this blog every day is that I am forced to read as much as I can. I have to be a sponge.
Right now, I am still reeling in excitement over the Sidewalk Toronto announcement and getting caught up on that reading.
This week Sidewalk Labs published the entire vision section of their RFP response to Waterfront Toronto. This is the response that won them the Quayside partnership. It’s 196 pages and can be downloaded here.
I’m still making my way through the package, which I am obviously going to do, but I thought this was a great diagram:
As is stated in their RFP response, inclement weather affects pedestrians and cyclists more than drivers. Toronto’s most notable response has been our PATH system, which pulls both people and retail below grade, away from the elements.
But Sidewalk’s research suggests that with the right wind, sun, and precipitation strategies, they may be able to 2x the number of comfortable outside hours per year here in Toronto. That’s what the above diagram shows.
Of course, there is so much more in their RFP response. But I need more time to digest it all. I’ll be sure to report back to all of you once I have done that. If you don’t feel like going through all 196 pages yourself, you can watch this 4 minute YouTube video instead.

One of the things that I have been wondering lately with all of the devastation caused by hurricanes Harvey and Irma is if we need to be viewing these catastrophic incidents as the result of climate change or if we’re being too quick to apply the availability heuristic.
The latter being: “Look at all of these horrible hurricanes. Climate change must really be here and happening right now.”
Albert Wenger is covering this topic on his blog right now through his “Uncertainty Wednesday” series and has also written similar posts in the past. The current series is still ongoing, but a few things stood out to me as I was going through the archives. I’ll mention 3 of them today.
Firstly, it’s important to understand the difference between weather and climate. Weather is what’s happening at any given moment. Climate, on the other hand, is the statistics of weather. Albert proposes the following definition for climate, which I like:
“Climate is the probability distribution of possible weather events.”
Secondly, the data is clear: We have gotten far better at forecasting weather over the years. Accuracy has greatly improved.
But we’re still pretty bad at it, particularly over longer periods of time. According this graph, we’re about 97.5% accurate for 3 day forecasts, but only about 40% accurate for 10 day forecasts. So by “longer periods of time”, I’m really talking about forecasts that go out beyond one week. That’s not very far into the future.
Thirdly, Albert has this post from last year where he talks about the flooding we saw on the U.S. east coast and also the slowing down of the Gulf Stream.
This is fascinating, and also frightening, because the Gulf Stream is a vital ocean current. Among other things, it warms western and northern Europe – likely making it warmer than it otherwise would be – and, according to some models, it lowers the sea level along the U.S. east coast by as much as 3 feet.
The frightening part is that as the Gulf Stream slows it also stops pulling away the same amount of water from the coast, which is arguably why mean sea level is increasing.
I say “arguably”, but the data clearly suggests an acceleration in the rate of rise. Here are two charts that Albert prepared. And there’s more: The U.S. east coast may also have it worse in terms of sea level rise precisely because of this phenomenon.
This is an interesting and, of course, important topic. This post obviously doesn’t do it justice, but I am trying to learn as much as I can. Writing always helps with that.
