GLOBAL WARMING Global warming refers to
an unequivocal and continuing rise in the average temperature of Earth's climate system.
Global warming refers to an average increase in the Earth's temperature, which in turn causes changes in the global climate.

Green House GasesMany chemical compounds found in the Earth’s atmosphere act as “greenhouse gases.” These gases allow sunlight,
which is radiated in the visible and ultraviolet spectra, to enter the atmosphere unimpeded. When it strikes the Earth’s surface, some of the sunlight is reflected as infrared radiation
(heat). Greenhouse gases tend to absorb this infrared radiation as it
is reflected back towards space, trapping the heat in the atmosphere.
Carbon dioxide is without doubt the most well known greenhouse gas,primarily through burning fossil fuels.

GHG Emissions IncreaseSince pre-industrial times atmospheric concentrations of
CO2, CH4 and N2O have climbed by over 31%, 15% and 17%, respectively.
Scientists have confirmed this is primarily due to human activity.
Carbon dioxide combustion of solid waste, fossil fuels (oil, natural
gas, and coal), and wood and wood products Methane :
production and transport of coal, natural gas, and oil. Methane emissions also result from the decomposition of organic wastes in municipal solid waste landfills, and the raising of livestock.

Nitrous oxide agricultural and industrial activities, as
well as during combustion of solid waste and fossil fuels.
hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6).
The average house is responsible for more air pollution and carbon dioxide emissions than is the average car.

Effects Of Global Warming In South Asia
The effects of global warming on the Indian subcontinent vary from the submergence of low-lying islands and coastal lands to the melting of glaciers in the Indian Himalayas, threatening the volumetric flow rate of many of the most important rivers of India and South Asia.
Lakshadweep, comprising tiny low-lying islands, are at risk of being inundated by sea level rises associated with global warming.

Methane emission from rice fields :
Methanogenesis, the process responsible for methane formation, occurs in all anaerobic environments in which organic matter undergoes decomposition.
Rice is generally grown in waterlogged condition, which creates an anoxic environment and is conducive to methane production by the strictly anaerobic methanogenic bacteria.

EFFECTS :-The effects of global warming are the ecological
and social changes caused (directly or indirectly) by human emissions of greenhouse gases.
Hurricanes and other storms are likely to become stronger.
Floods and droughts will become more common.Some diseases will spread, such as malaria
carried by mosquitoes.Ecosystems will change—some species will
move farther .
11
HURRICANES Hurricanes are
increasing in numbers and in severity, Hurricanes require warm ocean temperatures in order to form.
12
DroughtAn increase in the
occurrence of drought – Areas that lack precipitation over a long period of time.
Higher temperatures bake moisture out of soil faster, causing dry regions that live at the margins to cross the line into full-blown crisis.
13
Ice is thinningAntarctica, home to these Adélie penguins, is heating up. The annual melt season has increased up to three weeks in 20 years.
14
Upsala Glacier, Argentina, which was once one of the grandest glaciers to ever exist, continues to shrink on a yearly basis
15
Prevention Promotion of Measures to Reduce
CO2 Emissions that Measures Related to Energy Supply and Demand.
Strengthening Energy Efficiency Standards of Housing and Buildings : The standards should target a 20% reduction in energy consumption for heating and cooling for housing and a 10% reduction for other buildings.
s Financial incentives should be offered for energy efficient housing and buildings
16
Stop Deforestation Because trees also take carbon dioxide from the air,
cutting down large numbers of trees causes carbon dioxide levels to rise even further.
Promotion of Energy Supply Side Measures to Reduce CO2 Emissions :
Promoting Construction of Nuclear Power Plants Promoting Measures for Electrical Load
Balancing Promotion of Measures Involving CO2 Sinks
Such as Afforestation, etc.

we must make the changes to our own lives that will better benefit the environment and global warming as a whole. Believe it or not, one person can make a difference!

Top 10 Things You can do to stop Global Warming 10.Plant a couple of additional trees around
your home.CO2 reduction = 20 lbs/year9.Use a push mower to cut your lawn instead of
a power mower.CO2 reduction = 80 lbs/year8.Replace your home’s refrigerator with a high-
efficiency model.CO2 reduction = 220 lbs/year
7.Buy food or other products with reusable or recyclable packaging instead of non-recyclable packaging.CO2 reduction=230 lbs/year
6.Replace your washing machine with a low-energy, low-water-use machine.CO2 reduction = 440 lbs/year
20
5. Install a solar thermal system to help provide your hot water.CO2 reduction = 720 lbs/year
4. Recycle all of your homes waste: newsprint, cardboard, glass and metal.CO2 reduction = 850 lbs/year
3.Leave your car at home two days a week (walk, bike or take public transportation to work instead).CO2 reduction = 1,590 lbs/year
2. Insulate your home, tune up your furnace, and install energy efficient shower heads.CO2 reductions = 2,480 lbs/year
1.Purchase a fuel efficient car (rated up to 32 mpg or more) to replace your most frequently used automobile. 21
