Will Canadian agriculture benefit from a longer growing season due to global warming ?

Answer 1

No, once Canadian farmers figure out that the growing season is getting longer, they will think they can procrastinate a little longer in the spring. Next thing you know, they will be so lazy that they won't even get out of bed until July and the entire farming economy in Canada will go down the proverbial drain.

Now, assuming that your question stems from some real desire to have another opinion on this hot topic, of course, increasing a reasonably short growing season (all other variables remaining the same), would benefit any country's agricultural sector.

Answer 2

It's by no means a sure thing.

Global warming will dramatically alter patterns of precipitation. That will mess up agriculture. Also weather patterns are very liable to be more extreme. Crops prefer steady weather.

The question is will the advantage of warmer weather overall be greater than the disadvantages? No one knows for sure, but scientists are very worried about global warmings' effects on agriculture around the world.
