GLOBAL

WARMING

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.

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.

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.

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.

5.Global Warming Cause: Increase in usage of

chemical fertilizers on croplands.

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.

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.

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

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.

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.

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.

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.

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.

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.

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.

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!

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.

•We should practice the

3R’s:

•REDUCE,

•REUSE and

•RECYCLE

•We should plant as many

trees as possible to reduce

Global Warming.
