Speaking of rising temps, climate change is worsening, and according to a 2013 draft report from the Intergovernmental Panel on Climate Change, it will have "widespread and consequential" impacts for the entire planet. According to the report, climate change will make human health problems worse in many regions. Temperature increases will affect food crops such as wheat, rice and maize in tropical and temperate regions.
The report also predicts dire political consequences, such as civil war, as climate change diminishes food production, increases poverty and wreaks havoc with the economies of many nations. Moreover, by 2100, sea levels will rise, displacing hundreds of millions of people, particularly for multiple areas of Asia [source: Guillen].
