As greenhouse gas concentrations increase across the globe in our atmosphere, we are observing
significant changes to our climate. How does climate change directly affect desert regions and
humans' ability to sustain in these regions?
Standard le
O Greenhouse gas increases will cause a greater amount of plant growth to occur in the areas formerly
designated as deserts. These areas will soon yield large timber and lumber harvests.
O Greenhouse gas increases will cause a greater amount of rainfall to occur in areas once designated as deserts.
These areas will be converted into more arable land for growing crops.
O Greenhouse gas increases will cause an increase in desert areas on Earth. Current desert areas will grow as
temperatures cause increased evaporation. Humans will migrate away from these areas of low water and
productivity
O Greenhouse gas increases will cause an increase in weathering of rock, providing an enriched soil content for
these areas. More animals will migrate to these warmer, more fertile areas, providing resources which humans
can consume.
