Climate change leads to more extreme weather: more frequent and powerful hurricanes, longer drought periods, and heavier rainstorms. This affects food production, particularly in areas where people already have little food. Small farmers living in poverty who are dependent on their own crops for food and income, are particularly vulnerable. When rain drowns the crops or they dry up for lack of rain, this leads to starvation and even more poverty. Climate change affects all people worldwide, but it hits the poor hardest.

Global problems and solutions

The UN Framework Convention on Climate Change (UNFCCC) establishes both the need to reduce emissions of climate gasses and the need for adaptation to climate change (internal link). The UN’s Intergovernmental Panel on Climate Change (link to IPCC) argues that if global temperatures increase beyond a limit of two degrees Celsius, climate change will become serious and uncontrollable. The panel draws up various “futures,” based on whether emissions are cut powerfully and quickly or are allowed to continue to rise. The most optimistic future scenario demands strong measures and large, immediate cuts. The Paris Agreement (link) commits the countries of the world to attempt to further limit the temperature rise to 1.5 degrees Celsius. The UN’s Sustainable Development Goal № 13 commits the leaders of the world to act immediately to combat climate change and its consequences. (link)
