The greenhouse gas emissions that have steadily spewed from cars and planes and factories, the technologies that powered a massive period of economic growth, came at an enormous cost to the planet’s health. Today, we know that absent any change in our behaviour, the average global temperature will rise as much as 4 degrees Celsius by the end of the century. Global sea levels will rise by up to 6 feet. Along with those shifts will come radical changes in weather patterns around the globe, But there’s an increasing understanding that even if every country that originally signed up for the Paris Agreement meets every single one of their stated goals, the Earth is still set to experience some dramatic changes. Some even argue that we’ve passed the tipping point; even if we stopped emitting today, we’d still see dramatic effects. And that means we need to start preparing for a different kind of climate future—primarily, in the way we build.
