Global warming is when the earth heats up(the temperature rises). It happens whengreenhouse gases (carbon dioxide, watervapor, nitrous oxide, and methane) trap heatand light from the sun in the earth’satmosphere, which increases thetemperature. This hurts manypeople, animals, and plants. Many cannottake the change, so they die. Menu
The “greenhouseeffect” is the warming thathappens when certaingases in Earth’satmosphere trap heat.These gases let in light butkeep heat fromescaping, like the glasswalls of a greenhouse. Menu
Sometimes the temperature can change ina way that helps us. The greenhouse effectmakes the earth appropriate for people to liveon. Without it, the earth would be freezing, oron the other hand it would be burning hot. Itwould be freezing at night because the sunwould be down. We would not get the sun’sheat and light to make thenight somewhat warmMenu
Many things cause global warming. One thingthat causes global warming is electricalpollution. Electricity causes pollution in manyways, some worse than others. In most cases, fossilfuels are burned to create electricity. Fossil fuels are made of dead plants andanimals. Some examples of fossil fuels are oil andpetroleum. Many pollutants (chemicals that pollutethe air, water, and land) are sent into the air whenfossil fuels are burned. Menu
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
Svante Arrhenius(1859-1927) was a He foundSwedish scientist that was that thethe first to claim in 1896 averagethat fossil fuel combustion surface temperature ofmay eventually result in the earth is about 15oCenhanced global warming. because of the infraredHe proposed a relationbetween atmospheric absorption capacity ofcarbon dioxide water vapor and carbonconcentrations and dioxide.temperature. Menu
This is called the natural greenhouse effect.Arrhenius suggested a doubling of the CO2concentration would lead to a 5oC temperature rise. He and Thomas Chamberlin calculated thathuman activities could warm the earth by addingcarbon dioxide to the atmosphere. This research wasa by-product of research of whether carbon dioxidewould explain the causes of the great Ice Ages. Thiswas not actually verified until 1987. Menu
The planet is warming, from North Pole to SouthPole, and everywhere in between. Globally, themercury is already up more than 1 degree Fahrenheit(0.8 degree Celsius), and even more in sensitive polarregions. And the effects of rising temperatures aren’twaiting for some far-flung future. They’re happening right now. Signs are appearingall over, and some of them are surprising. The heat isnot only melting glaciers and sea ice, it’s also shiftingprecipitation patterns and setting animals on themove. Menu
1. Ice is melting worldwide, especially at theEarth’s poles. This includes mountain glaciers, icesheets covering West Antarctica and Greenland, andArctic sea ice.2. Sea level rise became faster over the last century.3. Precipitation (rain and snowfall) has increasedacross the globe, on average.4. Hurricanes and other storms are likely to becomestronger.5. Sea levels are expected to rise between 7 and 23inches (18 and 59 centimeters) by the end of thecentury, and continued melting at the poles could addbetween 4 and 8 inches (10 to 20 centimeters).
People are doing many things to try to stopglobal warming. One thing people are doing iscarpooling. Carpooling is driving with someone toa place that you are both going to. This minimizes the amount of greenhouse gasesput into the air by a car. Another thing that peopleare doing is being more careful about leaving thingsturned on like the television, computer, and thelights. Menu
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
Planting trees and recycling also helps. If yourecycle, less trash goes to the dump, and lesstrash gets burned. As a result, there are fewergreenhouse gasses in our atmosphere. Menu
1. We plan to offer honest value comparisons ofproducts such as hybrid cars.2. Choice of building materials is just one part ofwhat is known as green building.Green building can best be described as the birth tograve process of building.
conclution : Remember to save our earth. Allwe need to do are plant new trees asmuch as we can and dorecycling, reducing and reusing.
