Water Shortages

 At least one sixth of the world suffers vulnerability from water shortages. Rising temperatures mean that there will be more rain and less snow in the mountains but also that snow will melt earlier in the year resulting in more water in rivers and streams much earlier than they should be.

At present, water scarcity affects around 2 billion people in the world. Due to climate change, severe and prolonged droughts will occur more often which will lead to a serious lack of water for many people, animals and crops. In contrast to droughts, glaciers are expected to disappear in a few decades which can either cause floods or more droughts. Animals are affected by extinction and people are more susceptible to diseases, or, even worse, death. To add to this factor, there will be a decrease in crops because of the temperature rise and lack of rain to help them grow.
