GOBAL WARMING
Global warming is the
long-term heating of
01
Earth's climate system
observed since the
pre-industrial period
(between 1850 and
GOBAL 1900) due to human
WARMING activities.
A greenhouse gas is a gas
that absorbs and emits
radiant energy within the
02
thermal infrared range,
causing the greenhouse
effect. The primary
greenhouse gases in Earth's
atmosphere are water GREENHOUSE
vapor, carbon dioxide,
methane, nitrous oxide, and GASES
ozone.
Effects that scientists had
predicted in the past
would result from global
