2. What is Global Warming ???
Global warming is the rise in the average temperature of Earth's atmosphere and oceans since
the late 19th century and its projected continuation. Since the early 20th century, Earth's mean
surface temperature has increased by about 0.8 °C (1.4 °F), with about two-thirds of the
increase occurring since 1980.
3. Some Gases Responsible for
Global Warming :-
Greenhouse gases are those that can absorb and emit
infrared radiation, but not radiation in or near the
visible spectrum. In order, the most abundant
greenhouse gases in Earth's atmosphere are:
1.Water vapour (H2O)
2.Carbon dioxide (CO2)
3.Methane (CH4)
4.Nitrous Oxide (N2O)
5.Ozone (O3)

among patients of diabetes who are elderly or very
young.
