DESCRIPTION

Animals Polar Bears :They need ice for survival. As the ice melts, it leaves fewer places for polar bears to hunt and raise their young. Less food to hunt and interruptions in reproduction is not good for polar bears. Penguins :Melting ice presents problems for penguins. Penguins feed on tiny organisms such as krill shrimp. These tiny organisms survive on algae, but the melting ice and rising temperatures are creating a decrease in algae. Global warming also affects the breeding habits of penguins, which will lead to an eventual decrease in population. Trout :Trout and other cold-water fish are suffering from a loss of habitat due to global warming. These fish need glacial temperatures to survive. The rising temperatures may mean doom for trout and other cold-water fish.

What is global warming?

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.

Natural Causes :Natural causes are causes created by nature. One natural cause is a release of methane gas from arctic tundra and wetlands. Methane is a greenhouse gas. A greenhouse gas is a gas that traps heat in the earth's atmosphere. Another natural cause is that the earth goes through a cycle of climate change. This climate change usually lasts about 40,000 years.

What causes global warming?

Man-made Causes :Man-made causes probably do the most damage. There are many man-made causes. Pollution is one of the biggest man-made problems. Pollution comes in many shapes and sizes. Burning fossil fuels is one thing that causes pollution. Fossil fuels are fuels made of organic matter such as coal, or oil. When fossil fuels are burned they give off a green house gas called CO2. Also mining coal and oil allows methane to escape. How does it escape? Methane is naturally in the ground. When coal or oil is mined you have to dig up the earth a little. When you dig up the fossil fuels you dig up the methane as well.

Is the hydrological cycle changing?

On a regional basis increases in annual precipitation have

occurred in the higher latitudes of the Northern Hemisphere

and southern South America and northern Australia. Decreases

have occurred in the tropical region of Africa, and southern

Asia. Due to the difficulty in measuring precipitation, it has

been important to constrain these observations by analyzing

other related variables. The measured changes in precipitation

are consistent with observed changes in stream flow, lake

levels, and soil moisture (where data are available and have

been analyzed).

Is sea level risi

ng?

Global mean sea level has been rising at an average rate of 1.7 mm/year (plus or

minus 0.5mm) over the past 100 years, which is significantly larger than the rate

averaged over the last several thousand years. D

epending on which greenhouse gas

increase scenario is used (high or low) projected sea-level rise is projected to be

anywhere from 0.18 (low greenhouse gas increase) to 0.59 meters for the highest

greenhouse gas increase scenario. However, this increase is due mainly to thermal

expansion and contributions from melting alpine glaciers, and does not include any

potential contributions from melting ice sheets in Greenland or Antarctica. Larger

increases cannot be excluded but our current understanding of ice sheet dynamics

renders uncertainties too large to be able to assess the likelihood of large-scale

melting of these ice sheets.

Examples of using energy and polluting the air:

• Turning on a light• Watching T.V.• Listening to a stereo• Washing or drying clothes• Using a hair dryer• Riding in a car• Heating a meal in the microwave• Using an air conditioner• Playing a video game• Using a dish washer

What are people doing to stop global warming?

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. 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. 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.

Kids can help too!

Although adults do many things to help stop global

warming, kids can do just as much. Kids can’t do

hard things like making a law, but we can do easier

things like not watching as much TV. You can listen

to your parents when they say, turn off your lights or

go play outside. Listening to them and actually

trying to help can help you, your environment, and

the world.

What are greenhouse gasses?

Greenhouse gasses are gasses are in the earth’s atmosphere that collect heat and light from the sun. With too many greenhouse gasses in the air, the earth’s atmosphere will trap too much heat and the earth will get too hot. As a result people, animals, and plants would die because the heat would be too strong.

What are the experts saying?"The current situation of the world in relation to

the climate problem is that we're in a car with bad

brakes drivingtoward a cliff in the fog, and the fog is the scientific

uncertaintyabout the details that prevents us from knowing exactly

where the cliff is. ... There's a chance we'll go over the cliff anyway but

prudencerequires that we try to stop the car.“

"The faster and deeper we cut our greenhouse

gas emissions in the next 10 years,

the better our chances of averting a tipping

point."
