Global warming is caused by greenhouse gases like carbon dioxide and methane trapping heat in the atmosphere. This is called the greenhouse effect. (1) Svante Arrhenius first proposed in 1896 that fossil fuel use could lead to enhanced global warming. (2) Effects of global warming include melting ice, rising sea levels, stronger storms, and shifting climate patterns. (3) People are addressing global warming by reducing emissions through actions like carpooling, recycling, and planting trees.

3. Global warming is when the earth heats up
(the temperature rises). It happens when
greenhouse gases (carbon dioxide, water
vapor, nitrous oxide, and methane) trap heat
and light from the sun in the earth’s
atmosphere, which increases the
temperature. This hurts many
people, animals, and plants. Many cannot
take the change, so they die.

4. The “greenhouse
effect” is the warming
that happens when
certain gases in Earth’s
atmosphere trap heat.
These gases let in light
but keep heat from
escaping, like the glass
walls of a greenhouse.
Menu

5. Sometimes the temperature can change in
a way that helps us. The greenhouse effect
makes the earth appropriate for people to live
on. Without it, the earth would be freezing, or
on the other hand it would be burning hot. It
would be freezing at night because the sun
would be down. We would not get the sun’s
heat and light to make the
night somewhat warm

6. Many things cause global warming. One
thing that causes global warming is electrical
pollution. Electricity causes pollution in many
ways, some worse than others. In most cases,
fossil fuels are burned to create electricity.
Fossil fuels are made of dead plants and
animals. Some examples of fossil fuels are oil
and petroleum. Many pollutants (chemicals that
pollute the air, water, and land) are sent into the
air when fossil fuels are burned.

7. Some other examples of using energy and
polluting the air are:
- Turning on a light
- Watching T.V.
- Listening to a stereo
- Riding in a vehicle
- Playing a video game

temperature.

9. This is called the natural greenhouse effect.
Arrhenius suggested a doubling of the CO2
concentration would lead to a 5oC temperature rise.
He and Thomas Chamberlin calculated that
human activities could warm the earth by adding
carbon dioxide to the atmosphere. This research was
a by-product of research of whether carbon dioxide
would explain the causes of the great Ice Ages. This
was not actually verified until 1987.

10. The planet is warming, from North Pole to
South Pole, and everywhere in between.
Globally, the mercury is already up more than 1
degree Fahrenheit (0.8 degree Celsius), and
even more in sensitive polar regions. And the
effects of rising temperatures aren’t waiting for
some far-flung future.
They’re happening right now. Signs are
appearing all over, and some of them are
surprising. The heat is not only melting glaciers
and sea ice, it’s also shifting precipitation
patterns and setting animals on the move. Menu

11. 1. Ice is melting worldwide, especially at the
Earth’s poles. This includes mountain
glaciers, ice sheets covering West Antarctica and
Greenland, and Arctic sea ice.
2. Sea level rise became faster over the last
century.
3. Precipitation (rain and snowfall) has
increased across the globe, on average.
4. Hurricanes and other storms are likely to
become stronger.
5. Sea levels are expected to rise between 7
and 23 inches (18 and 59 centimeters) by the
end of the century, and continued melting at the
poles could add between 4 and 8 inches (10 to
20 centimeters).

12. People are doing many things to try to stop
global warming. One thing people are doing is
carpooling. Carpooling is driving with someone
to a place that you are both going to.
This minimizes the amount of greenhouse
gases put into the air by a car. Another thing
that people are doing is being more careful
about leaving things turned on like the
television, computer, and the lights.
Menu

13. A lot of people are taking time away
from the television, and instead, they are
spending more time outdoors. This helps
our planet out a lot. Now, more people are
even riding busses, walking to school, and
riding their bikes to lower the amount of
greenhouse gases in the air.
Menu

14. Planting trees and recycling also helps. If
you recycle, less trash goes to the
dump, and less trash gets burned. As a
result, there are fewer greenhouse gasses
in our atmosphere.
Menu

15. 1. We plan to offer honest value comparisons
of products such as hybrid cars.
2. Choice of building materials is just one part
of what is known as green building.
Green building can best be described as the
birth to grave process of building.

16. conclution :
Remember to save our earth. All
we need to do are plant new trees as
much as we can and do
recycling, reducing and reusing.

from damage
