1. GLOBAL
WARMING

2. WHAT IS GLOBAL WARMING?
Global warming means the rise in the Global temperature. The
primary cause for Global Warming are human activities such as
burning fossil fuels to release poisonous gases to our
environment and destroying forests from which we cannot get
enough oxygen so that is why carbon-dioxide is increasing in
the environment which traps more sunlight and drives up the
planet’s temperature causing the glaciers to melt, rise in the
sea level and forests to dry etc. These are the reasons why we
say the humans are major cause for the Global Warming.

3. CAUSES OF THE GLOBAL WARMING
One of the biggest issues facing us right now is global warming. Its
effects on animals and on agriculture are indeed frightening, and the
effects on the human population are even scarier. The facts about global
warming are often debated in politics and the media, but, unfortunately,
even if we disagree about the causes, global warming effects are real,
global, and measurable. The causes are mainly from us, the human
race, and the effects on us will be severe.

4. 1. Global Warming Cause: Carbon dioxide
emissions from fossil fuel burning power plants.
2.Global Warming Cause: Carbon dioxide
emissions from burning gasoline for
transportation.

5. 3. Global Warming Cause: Methane emissions
from animals, agriculture such as rice paddies and
from Arctic sea beds.
4. Global Warming Cause: Deforestation,
especially tropical forests for wood, pulp, and
farm land.

6. 5.Global Warming Cause: Increase in usage of
chemical fertilizers on croplands.

7. IMPACT OF GLOBAL WARMING ON
THE ENVIRONMENT
1.Accelerating sea level rise and increased
coastal flooding:
Global Warming is now accelerating the rate of sea level rise ,
increasing flooding risks and high risk at coastal areas.
2. Longer and more damaging wildfire seasons:
Wildfires are increasing and wildfire season is getting longer as
temperatures rise. Higher spring and summer temperatures as ice
melts earlier.

8. 3.More frequent and intense heat waves:
Dangerously hot weather is already occurring more frequently than it did
60 years ago. This increase in heat waves creates serious health
risks, and can lead to heat exhaustion, heat stroke, and aggravate
existing medical conditions.
4.National Landmarks at Risk:
The growing consequences of climate change are putting many of the
country's most iconic and historic sites at risk.

9. 5.Widespread forest death in the Rocky
Mountains:
Tens of millions of trees have died in the Rocky Mountains over the past
15 years because of tree-killing insects, wildfires and stress from heat
and drought.
6.Costly and growing health impacts:
Rising temperatures will likely lead to increased air pollution, a longer
and more intense allergy season, the spread of insect-borne
diseases, more frequent and dangerous heat waves, and heavier
rainstorms and flooding

10. 7.An increase in extreme weather events:
Strong scientific evidence shows that global warming is increasing
certain types of extreme weather events, including heat waves,
coastal flooding, extreme precipitation events, and more severe
droughts. Global warming also creates conditions that can lead to
more powerful hurricanes.
8. Heavier precipitation and flooding:
As temperatures increase, more rain falls increasing the risk of flooding
events which can cause severe damage to our Environment and
habitats of many living things including humans and animals.

11. 9. Lack of Food:
This is because when there would be more carbon-dioxide in Earth
rather than oxygen, the farms and fields would start to dry out instead
of growing and even because of floods which occur due to the rise in
sea level which will destroy the pastures and fields.

12. SOLUTIONS OF GLOBAL WARMING
There is no single solution to global warming, which is primarily a
problem of too much heat-trapping carbon dioxide (CO2), methane
and nitrous oxide in the atmosphere .The technologies and
approaches outlined below are all needed to bring down the
emissions of these gases by at least 80 percent by mid-century.
Achieving goal is possible because nothing is impossible.

13. Greening transportation:
A variety of solutions are at hand, including improving efficiency (miles per
gallon) in all modes of transport, switching to low-carbon fuels, and reducing
vehicle miles traveled through smart growth and more efficient mass
transportation systems.
Revving up renewables :
Renewable energy sources such as solar, wind, geothermal and bio energy are
available around the world. Multiple studies have shown that renewable
energy has the technical potential to meet the vast majority of our energy
needs. Renewable technologies can be deployed quickly, are increasingly
cost-effective, and create jobs while reducing pollution.

14. Phasing out fossil fuel electricity:
Dramatically reducing our use of fossil fuels, especially carbon-intensive coal
is essential to tackle climate change. There are many ways to begin this
process. Key action steps include: not building any new coal-burning power
plants, initiating a phased shutdown of coal plants starting with the oldest
and dirtiest, and capturing and storing carbon emissions from power plants.
Demonstration projects to test the viability and costs of this technology for
power plant emissions are worth pursuing.

15. Managing forests and agriculture:
Taken together, tropical deforestation and emissions from agriculture represent
nearly 30 percent of the world's heat-trapping emissions. We can fight global
warming by reducing emissions from deforestation and forest degradation
and by making our food production practices more sustainable.
Exploring nuclear:
Because nuclear power results in few global warming emissions, an increased
share of nuclear power in the energy mix could help reduce global
warming—but nuclear technology poses serious threats to our security and,
as the accident at the Fukushima Diarchy plant in Japan illustrates to our
health and the environment as well.

16. Developing and deploying new low-carbon and
zero-carbon technologies:
Research into and development of the next generation of low-carbon
technologies will be critical to deep mid-century reductions in global
emissions. Current research on battery technology, new materials for solar
cells, harnessing energy from novel sources like bacteria and algae, and
other innovative areas could provide important breakthroughs.
Ensuring sustainable development:
A successful global compact on climate change must include financial
assistance from richer countries to poorer countries to help make the
transition to low-carbon development pathways and to help adapt to the
impacts of climate change.

17. Energy Efficiency:
May well be the most rapid and cost-effective tool to reducing carbon dioxide
(CO2) emissions, yet it is still overlooked by many businesses and
governments. Increases in energy efficiency must be seen as a crucial part
of reducing CO2 emissions and minimizing our dependence on fossil fuels.
Renewable Energy :
Generated from natural sources – water, wind, solar, biomass or geothermal –
will play a key role in replacing the world's dependence on fossil fuel based
energy sources, such as coal, oil and natural gas which are not renewable.
This means once that source of energy has been used, it is gone!

18. Carbon-capture and storage (CCS) :
It is technology that removes and stores the CO2 during the production of
energy from fossil fuels. With further research and investment, CSS
technology may prove to be the bridging technology needed to 'get us over
the line.
Preventing forest loss:
It will go a long way to reducing the threat of climate change. Forests are the
largest storehouse of carbon, after coal and oil. When they are destroyed by
logging and clearing for developing , massive quantities of CO2 is released
into the atmosphere.

19. •We should practice the
3R’s:
•REDUCE,
•REUSE and
•RECYCLE
•We should plant as many
trees as possible to reduce
Global Warming.
