Global warming
rapid rate of increasing temperatures
Thick, light-colored low-altitude clouds
decrease surface temperature
Thin, cirrus clouds at high altitudes
increase surface temperature
Prolonged droughts
grasslands become dustbowls
Organisms that increase global warming
Insects, fungi, and microbes
Monsoons
Climatic systems anywhere in which the moisture increases dramatically in the warm season
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
