If global climate change causes a temperate grassland region to get less rainfall and higher temperatures, it will start to support more desert species.
Global climate change refers to long-term average changes over the whole planet. These include rising temperatures and precipitation changes, as well as the repercussions of global warming, such as: Sea levels are rising. Mountain glaciers are receding.
Climate change will most certainly impact the makeup of grassland communities, but complex interactions make forecasts difficult. 
Extreme weather events can cause a swift and severe reaction, affecting both ecosystems and human groups . Droughts, floods, fires, and hurricanes are anticipated to have a greater impact on grassland ecosystems in the United States. Drought worsens soil erosion and depletes aquifers. Increased precipitation variability favors more frequent fires, that can minimize the encroachment of woody plants into grasslands.
Therefore, the blank will be filled by begin to support more desert species.
