same effect is caused on the earth as that is caused by the greenhouse net or glass on the
warming atmosphere inside the greenhouse. The greenhouse net or glass causes heat inside
the greenhouse. It traps the heat waves from going outside. A similar effect occurs in the
atmosphere inside the car when its windows are closed in sunlight.
The same effect is caused on the earth by gases like carbon dioxide and water
evaporation. They are called āgreenhouse gasesā; they act as greenhouse nets or glass,
which means these gases allow visible light of the sun to reach the surface of the earth but
obstruct or blanket or cover reflected rays from the earth from going outside.
In short, greenhouse gases allow the short waves of incoming solar radiation to
come in but do not allow the long waves of outgoing terrestrial radiation to escape. Thus,
global warming is an effect of greenhouse gases.

Global Warming:-
Global warming means the earth's warming due to rapid build-up in the atmosphere
of carbon dioxide and other greenhouse gases that trap the earthās heat. It also leads to
climate change.

Reasons for Increase in Green House Gases:-
Greenhouse gases are increasing due to emissions from a large number of industries,
vehicles, waste dumps, and other sources. Carbon dioxide emissions from these sources
are the root cause of global warming.
An increase in greenhouse gases results in global warming, which may destroy the
earth's life in a short period. Global warming will result in hotter summers and colder
winters, rising sea levels, changes in monsoon patterns, droughts, floods, and melting
icebergs.

International Efforts to Prevent Global Warming:-
The world has become serious about the increasing threat of global warming.
However, developed countries that emit carbon dioxide have made fewer efforts to reduce
their emissions.
Developed countries such as the U.S.A, European Union, China, Japan, etc., have
made some efforts to reduce greenhouse gases. In November 2014, the U.S.A. and China
recently agreed at the G-20 summit to reduce their greenhouse gas emissions in a time-
bound manner.
However, the Rio Conference and the Kyoto Conference in 1997 have contributed
to some extent to taking steps to reduce global warming.
