Global Warming

Pessoal, venho pedir desculpa por não ter vindo aqui postar nada, mas os testes não me têm permitido! Agora, como esta semana já não tenho testes, posso pôr aqui um trabalhinho de Inglês sobre o ambiente - "Environmental".

O trabalho fala-nos sobre o "global warming", ou seja, o aquecimento global do Planeta Terra.

What causes global warming?

Carbon dioxide and other air pollution that is collecting in the atmosphere like a thickening blanket, trapping the sun's heat and causing the planet to warm up. Coal-burning power plants are the largest U.S. source of carbon dioxide pollution -- they produce 2.5 billion tons every year. Automobiles, the second largest source, create nearly 1.5 billion tons of CO2 annually.Here's the good news: technologies exist today to make cars that run cleaner and burn less gas, modernize power plants and generate electricity from non-polluting sources, and cut our electricity use through energy efficiency. The challenge is to be sure these solutions are put to use.

Is the earth really getting hotter?

Yes. Although local temperatures fluctuate naturally, over the past 50 years the average global temperature has increased at the fastest rate in recorded history. And experts think the trend is accelerating: the 10 hottest years on record have all occurred since 1990. Scientists say that unless we curb global warming emissions, average U.S. temperatures could be 3 to 9 degrees higher by the end of the century.
