Global opvarmning: årsager, effekter og løsninger

About global warmingWell, if we look some years back, there is a big change. The earth is already showing many signs of worldwide climate changes. The human activity has been increasing the global warming. The global warming, which is also called a greenhouse effect, this is very dangerous, because glaciers are melting, so the sea level rises. If the global overheating won’t stop, many regions and not only those, which are neighbouring with some sea or ocean, will be covered by the sea. Also water pollution is a very big problem of our present world, especially for sea animals. Sometimes, the climate has warmed so that the oceans have risen and covered much of the earth.

Now the question is how we use CO2 in our every day. It’s actually when we drive or when we use electricity, the waste of chemical and that entire stuff which provides CO2. Last year, 2001, was the second warmest year since recordkeeping began in 1867.Which problems can global warming create? It can create problems for our environment. It will give us an uneasy life, because there will come allot of flooding.It will create problems for our well being.We will get hotter summers because the atmosphere will heat up and the globe too. We will see more ice in summers and it will be really cold.How can we help avoiding the problem of global warming in our everyday? We could e.g. change our lifestyle. We could use the cycle or public transport rather than driving in car. Because a car use allot of fuel. Whenever we use electricity, we help put greenhouse gases into the air. By turning off lights, the television, and the computer when you are through with them, you can help a lot.The greenhouse effect The Earth receives energy from the Sun mostly in the form of visible light.Carbon dioxide, water vapor (), methane (), nitrous oxide (), and a few other gases are greenhouse gases.If these greenhouse gases didn’t exist our planet surface would be as cold as the moon. The Earth’s atmosphere is all around us. It is the air that we breathe. Greenhouse gases in the atmosphere behave much like the glass panes in a greenhouse. Sunlight enters the earth's atmosphere, passing through the blanket of greenhouse gases. The greenhouse effect is important. Without the greenhouse effect, the Earth would not be warm enough for humans to live. But if the greenhouse effect becomes stronger, it could make the Earth warmer than usual. Even a little extra warming may cause problems for humans, plants, and animals.Weather Weather is what happens from minute to minute. The weather can change a lot within a very short time. For example, it may rain for an hour and then become sunny and clear. Weather is what we hear about on the television news every night. Talk to your family and friendsTalk with your family and friends about climate change. Let them know what you've learned and how to help pus self out of this problem. Bike, Bus, and WalkYou can save energy by sometimes taking the bus, riding a bike, or walking.Think about it, before you buyThere are lots of ways we can improve the environment. One of the ways to reduce the amount of greenhouse gases that we put into the air is to buy products that don't use as much energy.How do we know what’s going to happenScientists don't know exactly what will happen in the future. But they can use special computer programs to find out how the climate may change in the years ahead. And the computer programs tell us that the Earth may continue to get warmer which is really dangerous. They tell us that the Earth's temperature will probably continue to rise as long as we continue increasing the amount of greenhouse gases in the atmosphere.So what’s the big deal?Sometimes little things can turn into big things. Like, if you don’t eat something to get thin you will possibly get sick, instead of eating some healthy food. It's the same thing with global temperatures. If temperatures rise above normal levels for a few days, it's no big deal. But if temperatures continue to rise over a longer period of time, then the earth may experience some problems.People all around the world talking about global warming today. Discussions about global warming, is important and must be continued until the world realizes that Global Warming is an issue that needs to be addressed. Global warming is about our planet. If we do not take action now, we will destroy our planet. [email protected] 17, 69, 93, 96
