Global warming refers to the average increase in Earth's temperature caused by greenhouse gas emissions from human activities like burning fossil fuels. Scientists predict average global temperatures could increase between 1.4 to 5.8°C by 2100, resulting in rising sea levels and more severe weather. The main greenhouse gases are carbon dioxide from fossil fuel combustion, methane from agriculture and landfills, and nitrous oxide from fertilizers. Reducing greenhouse gas emissions 50-80% through increased renewable energy, electric vehicles, carbon capture, and reforestation could stabilize temperatures.

2. GLOBAL WARMING
- refers to an average increase in the
Earth's temperature, which in turn causes
changes in climate.
- The increased volumes of carbon dioxide
and other greenhouse gases released by the
burning of fossil fuels, land clearing,
agriculture, and other human activities, are
believed to be the primary sources of the
global warming that has occurred over the
past 50 years.

3. - Scientists from the Intergovernmental Panel on
Climate carrying out global warming research
have recently predicted that average global
temperatures could increase between 1.4 and 5.8
°C by the year 2100.
- resulting from global warming may include rising
sea levels due to the melting of the polar ice caps,
as well as an increase in occurrence of storms and
other severe weather events.

4. CAUSES
 there are several greenhouse gases
responsible for warming, and humans emit them
in a variety of ways. Most come from the
combustion of fossil fuels in cars, factories and
electricity production.
 The gas responsible for the most warming is
carbon dioxide, also called CO2. Other
contributors include methane released from
landfills and agriculture , nitrous oxide from
fertilizers, gases used for refrigeration and
industrial processes.

5.  A molecule of methane produces more than 20 times
the warming of a molecule of CO2. Nitrous oxide is
300 times more powerful than CO2.
 Global warming occurs when carbon dioxide (CO2)
and other air pollutants and greenhouse gases collect
in the atmosphere and absorb sunlight and solar
radiation that have bounced off the earth’s surface.
Normally, this radiation would escape into space—but
these pollutants, which can last for years to centuries
in the atmosphere, trap the heat and cause the planet
to get hotter. That's what's known as the greenhouse
effect.

6.  Due to global warming, there is increased
probability and intensity of droughts and heat
waves.
 As the temperature of oceans rises, so will the
probability of more frequent and stronger
hurricanes.
 In future, towns of India like Mumbai, Chennai etc.
may be covered with water due to global warming
as such towns are situated on the bank of sea. As
a consequence of this, the population of the
country will decrease.

7.  The effect of global warming in India vary from
submergence of low lying islands and coastal
lands to the melting of glaciers in the Indian
Himalayas.
 Polar ice caps melting due to global warming will
raise sea levels.
 Temperature rises and changing landscapes will
endanger several species of animals.
 If Ice caps melt, the only reflector is the ocean;
darker colours absorb sunlight, further warming
the Earth.

8. SOLUTION
 A commonly cited goal is to stabilize GHG
concentrations around 450-550 parts per million
or about twice pre-industrial levels. This is the
point at which many believe the most damaging
impacts of climate change can be avoided.
Current concentrations are about 380 ppm, which
means there isn't much time to lose. According to
the IPCC, we'd have to reduce GHG emissions by
50% to 80% of what they're on track to be in the
next century to reach this level.
 Many people and governments are already
working hard to cut greenhouse gases.

9.  There are many possible wedges, including
improvements to energy efficiency and vehicle fuel
economy (so less energy has to be produced),
increases in wind and solar power, hydrogen
produced from renewable sources, biofuels
(produced from crops), natural gas, and nuclear
power. There is also the potential to capture the
carbon dioxide emitted from fossil fuels and store
it underground—a process called “carbon
sequestration."

10.  we can also increase the amount of gases we
take out of the atmosphere. Plants and trees
absorb CO2 as they grow, "sequestering" carbon
naturally. Increasing forestlands and making
changes to the way we farm could increase the
amount of carbon we're storing.
