Climate Wars, The Fight for Survival as the World Overheats by Gwynne Dyer published in 2010. Because of climate change and global warming, we are concerned about more and stronger storms, and rising oceans. In the future, we should also be concerned about expanding deserts and shrinking supplies of food. Before they allow their populations to starve, governments will make war on each other to access the shrinking supplies of food. Thus starving to death is the ultimate danger of climate change. In addition, some scientists believe that the atmosphere will contain less oxygen making it harder to breathe.
