decrease surface temperature
Thin, cirrus clouds at high altitudes
increase surface temperature
Prolonged droughts
grasslands become dustbowls

Jet Stream
Current of fast-moving air found in the upper levels of the atmosphere
Global change
changes in the biological, physical, and chemical properties of Earth
Global climate change
