That is what I was going to get to. It will be a big cost for both alternatives. One is adapting to a net-zero future and changing our economy to make sure that happens. That will come at a cost. But the cost of inaction.... There is no null alternative left, right?
We can't just say, we're going to continue with the status quo, because our carbon budget will be broken. We'll break the bank in terms of our GHG emissions and how much will be in the upper atmosphere heating the planet, which will just have a different type of cost for us in the form of flooding and premature deaths from heat waves and so on. Unfortunately, because of 38 years of inaction, globally and in Canada, we're facing two unattractive options: a major restructuring to reach net zero, or, if we don't do that, a more catastrophic level of climate change, with mass migrations and extinctions and so on.
