Opinion essay complete

In this essay I will be discusing the issue of global warming. This issue is very important because it involbes all the world. I will examine arguments for and against this topic and I will also draw a conclusion based on the facts

First, the global warming is a very important problem that we have to solve. Global warming is the increase of the temperature in all the world. National Geographic website on 2007 explain us the impacts of the increasing temperatures. One of the impacts is the ice melting worlwide. That simple issue brings a lot of horrible consecuences. One of those consecuences is the rise of the sea level. This riseing became faster over the last century. By the end of the century sea levels are expected to rise between 18 and 59 centimeters. Also the ice of the mountains will disappear, so we will not have fresh water to drink.

Other very important consecuence of global warming is the destruction of the ozono layer. The enormous quantitis of CO2 in the air are destroying the ozono layer getting the UV rays hit the Earth directly affecting all the popullation. If the ozono layer disappear, the levels of radiation will increase and of course all people all people affected. There are many diseases caused by UV rays like: skin cancer and eyes problems. Also this may cause problems in the nature, destroying vegetation, that form part of other animals diet, this will affect all thr food chain

On the website thelegraph.co.uk they say  that global warming dosen't exist. They say that the Earth was hotter 1000 years ago, but I think that the website is wrong.  Global warming is a very important actual problem. Many scientist said that they are  searching ways to stop it and prevent the future impacts

Finally I will like to remind you that the only way to prevent this horrible catastrof named global warming is reducing the contamination. That means, reduce. This is a auful reality, global warming exist and we have to do all posibie things to stpo it.

Can I count on you?

Some impacts from increasing temperatures are already happening.

• 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.
• Researcher Bill Fraser has tracked the decline of the Adélie penguins on Antarctica, where their numbers have fallen from 32,000 breeding pairs to 11,000 in 30 years.
• Sea level rise became faster over the last century.
• Some butterflies, foxes, and alpine plants have moved farther north or to higher, cooler areas.
• Precipitation (rain and snowfall) has increased across the globe, on average.
• Spruce bark beetles have boomed in Alaska thanks to 20 years of warm summers. The insects have chewed up 4 million acres of spruce trees.

Other effects could happen later this century, if warming continues.

• 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).
• Hurricanes and other storms are likely to become stronger.
• Species that depend on one another may become out of sync. For example, plants could bloom earlier than their pollinating insects become active.
• Floods and droughts will become more common. Rainfall in Ethiopia, where droughts are already common, could decline by 10 percent over the next 50 years.
• Less fresh water will be available. If the Quelccaya ice cap in Peru continues to melt at its current rate, it will be gone by 2100, leaving thousands of people who rely on it for drinking water and electricity without a source of either.
• Some diseases will spread, such as malaria carried by mosquitoes.
• Ecosystems will change—some species will move farther north or become more successful; others won’t be able to move and could become extinct. Wildlife research scientist Martyn Obbard has found that since the mid-1980s, with less ice on which to live and fish for food, polar bears have gotten considerably skinnier.  Polar bear biologist Ian Stirling has found a similar pattern in Hudson Bay.  He fears that if sea ice disappears, the polar bears will as well.

Clean and Renewable energy: This is second only to climate change. The human race is faced with the environmental problem of cleaning up or replacing the burning of fossil fuels that enhanced industrial revolution during 18th century. Unless a clean and renewable energy is found as an alternative, our planet risks being turned into an inhabitable and hostile not fit for human survival. There is need for the development and adoption of clean energy.
