Apparently a country's peak productivity corresponds to a temperature of 13 degrees Celsius. [1] So, in isolation you are correct, as higher average temperatures for cold places like Canada or the Scandinavian countries increase, they might actually increase productivity. However, this will be undermined by the instability and worsening productivity of the rest of the world. We're all in this together.
