My issue is that the problem is more about "energy" than heat. While the average over time will be a gradual warming, the impacts locally will be much different on the time scales normal people care about. We should be talking about weather extremes, not "heat." When we say the earth is going to get warmer, people think "fine, Canada is kind of nice anyways." In reality, we'll also see extreme blizzards, floods/rain, tornados, insect swarms, mass deaths of flora/fauna, and more. Pretty much all natural phenomena will be amplified both in terms of frequency as well as severity. And we may have many years before that 2.whatever C warming trend is realized, extreme weather events are increasing now. My home was almost leveled this year by an F4/5 tornado this year in an area where tornados are typical but never much more than an F2.
