No they won’t. They already died from nuclear war, nuclear winter, the end of oil, the coming ice Age, the end of birds, , Africanized Honeybees, the end of bees, no food, GMO food, AIDS, Swine Flu, Bird Flu, asteroids, Yellowstone, holes in the ozone, AR-15s, and the zombie-frickin-apocalypse.
A 3 degree temperature rise isn’t even worth being on that list!
Actually, the geologic history /many times repeated pattern says we WILL have another serious period of glaciation fairly soon (geologically speaking, a blink of an eye), and it’s a pretty good bet that’ll be very deadly if we humans don’t prepare well.
Heck, we may actually do better than we are now with a 3 deg. temperature rise!
Life flourishes on earth when CO2 levels are high. It is plant food. During the Triasic, Jurassic and Cretaceous CO2 levels were much higher than today, many times higher.
Plants flourished and thus provided the means for giant dinosaurs to live. The huge coal deposits of the Carboniferous were made by these increased CO2 levels. In reality today we are living in a CO2 desert. High CO2 levels insure great growth of plant life and food. Low CO2 levels can lead to an extinction event. In reality today we are living not far above extinction event levels of CO2.
CO2 IS PLANT FOOD!
