The radiation goes up and down when the northern hemisphere tilts towards and away
from the sun. Each the the hemispheres tilts towards the sun and then alternates
The higher the CO, higher the temperature
Ocean absorbs the sun more than the ice resulting in a faster built up of heat
Infectious diseases expanding and emerging as warm temperature increases
Four Low line areas likely to be flooded Netherlands, florida, bangladish, new orleans
Type of ice thickness that will make it easy for the submarine to come out:
Results of global warming are relocation and precipitation
