If this old planet is warming up......
future generations in the temperate zones better prepare for the expansion of disease vectors and the diseases those vectors spread to other critters and plants.
Look at the multitude of deadly diseases as one nears the equator. Prepare for those diseases to infest your neck o' the woods.
Malaria will be a threat along with a horde of other nasties just waiting to molest thee.
Gotta' expect various protozoa, bacteria, viri, parasites of all types and a bunch of other yucky things knocking at your door, wanting to feast upon and within you.
You, dear BITOGER, may be dinner for who knows what will come creeping northwar or southward, depending upon if ye atand upright upon the Earth (northern hemisphere) or are dangling from the bottom of the planet (southern hemisphere).
Oh.... okay, so thos crotchety old coot is "north-centric." Whatcha' gonna' do about it? Meet me at the bike rack after school and beat me up?
Nyah nyah nyah nah nah.... neener neener neener.
Whatever the case...... this writer, the Mighty Obbop, shanty-dwelling corpulent admirer of food, will assuredly cease cellular reproduction long before the apparent global warming leads to the spread of the horrors mentioned above.
Let the future worry about it I wail. Besides, with Murphy's Law always lurking upon the horizon, akin to a Pablo-type rock or a Rex-type lizard thing crawling through the pipe work, just as things really begin to "heat up" (note deft pun, kinda' clever in a juvenile way, right? RIGHT?!!!) I, the Mighty Obbop, would expect the sudden appearance of a 30-mile-wide nickel-iron meteor to impact the planet at 30,000 miles-per-second, thus rendering all concern about global warming null and void, along with the human species that could conceivably also become null and void.
