Heat

Ultra violet rays

Some heat stays in atmosphere.

Ultra violet rays don´t stay.

MethaneNaturally it is formed in marshes

and bogs. Dead plants and animal decay

and by the termites.Human beings produce methane

by growing rice, farming cattle, burning waste

and burning fossil fuels.

Nitrous Oxide

Naturally it is produced by oceans and by lightening strikes.Humans have increased it by the production of nylon and fertilisers.

Carbon DioxideNaturally it is produced by the animals when they breathe,

dead animals, plants, and forest fires.

Humans have increased the amount by burning fossil fuels like coal, oil and gas,

and by destroying forests.

*The temperature increased by 1 degrees. It will increase 13 to 9 degrees if we don't stop it by the end of the century.

*Global warming in the Arctic is happening now. The report concludes that the northern ice cap is warming at twice the global rate and that this will lead to serious consequences for the planet.

Hydroelectric power uses the energy of mowing water to make electricity.

Fuel hydro plant renewable Very low cost

Another benefit is that hydro plants do not affect air quality.

The force of moving water is very powerful and uses that force to generate electricity.

Dams that create moving water .

♪Gates that can open or close.

♪ Control the water flowing over the dam.

Hydrothermal *Uses steam and hot water Geopressurize

d *Uses hot water (around 350°F) and hydraulic turbines

Petrothermal *Uses dry hot rocks requiring water injections to make steam.

Solar Power is energy produced by the sun in the form of heat and light.

Solar energy is clean Doesn`t pollute There is lots of it It is renewable fuel

Wind

Windmils turn with wind

This generates electricity

♪Urgent need of strategies

♪ to reduce the potential impact of greenhouse gas emissions

♪ that result from economic development in developing nations

What would you do to help Global

Warming?I would help the Global Warming

by recycling all the garbage:1)You have to tell all your friends

to do all the same.2)If you see something fallen on

the floor pick it up.3)Don’t waist paper or something

that you can recycle.

People are

suffering of

climate changes.

No doubts about

why there is this

climate: all the

papers and

cutting down

trees and things

that contaminates

the floor, air and

water in all the

world are melting

the two poles

that's why there

are a lot of

hurricanes and

rains exc.

Hail

Hurricanes and storms

Strong rain and

wind

If we recyle all the things is better for the climate!!

If we dont throw all the garbage and we dont cut trees we would have a better world.

At school we could do projects that says we have to recyle papers and not to cut trees and with a group of people hang them in the walls all arownd the school!!
