It is important to remember that ice sheets absorb a great deal of the sun's heat.
Ice caps also to do their part in reflecting the sun’s rays which keep the Earth cooler (see albedo).
Without a decent reflective shield and solid heat absorption mechanism, the troposphere will further rise in temperature.
Rising Sea Levels
It is simple science and logic; with excess water comes rising sea levels which have the potential of swallowing islands and nations whole.
determined that the burning of fossil fuels is the main cause of climate change
The possible solution is to end the dependence on oil, which would allow to maintain the increase in temperature below 2 ° C, beginning to avoid the worst effects of climate change on the planet.
