Climate Changes & Threats
Most deserts are likely to become even more extreme if a climate changes as projected by current scenarios; most desert regions are expected to become hotter and most will probably not become significantly wetter. CO2 helps plants use water more efficiently, and levels of this are expected to double by 2050. The boom in plant growth will certainly affect it's ecosystem. If temperature continues to increase globally, deserts will get hotter and hotter and fires will spark up as well as animals being unable to handle the intense heat. Rainfall will decrease even more and while most plants and animals there have adapted to living with little water, they could not live without water completely.
