  • By 2030, 8 years from now, crop yields of Maize are projected to decrease by 24%. These are grown in many areas but especially in land closer to the equator where temperature increases will be felt the most creating displacement of those communities. Wheat production is expected to increase by 17% in northern areas of the US, China, and Canada as examples.

  • In the past certain natural disasters followed predictable patterns allowing communities and households to prepare for them. With the Earth becoming warmer, there is increased energy the atmosphere and oceans. These have extended wildfire and drought seasons, intensified hurricanes, and increased coastal flooding.
