Global warming is the process of earth’s atmosphere heating up. Over the last 100 years, the average temperature of earth’s atmosphere has gone up 1 Fahrenheit. The weather has not changed exactly the same way in every area of the planet. But scientists think that the rise in average temperature is already affecting the earth’s climate.
Many scientists now believe that global warming is caused by cutting down trees, producing more trash, and polluting the environment which are some of the reasons why the temperature has gone up. Many scientists believe that the biggest causes of global warming are new human technologies that release greenhouse gases into the atmosphere.
The greenhouse effect is not new. Certain gases in the atmosphere, like carbon dioxide, nitrous oxide and methane, making it hard for heat energy to go into space. In the past, the climate didn’t change much because nature produced just the right amount of greenhouse gases to deal with it.
Today, most scientists are pretty sure that the rising temperature can’t be blamed on nature. Ever since the industrial revolution in the 1700s, humans have relied on machines for daily life. And many of those machines give off a lot of greenhouse gases. An increase in the release of greenhouse gases from human activities is throwing nature off balance.
The climate is a very complicated thing, but many scientists agree that the rising atmospheric temperature has already damaged the environment. Sheets of ice, called glaciers, are melting in Antarctica and other parts of the globe. As glaciers break off and melt into the oceans, they are adding warm water to the oceans and causing the sea level to rise.
Over the past 100 years, the sea level has risen 6-8 inches around the world. That means land along the coasts is beginning to disappear under water. Bigger and warmer oceans are also adding to other weather problems caused by pollution in the atmosphere. Some places have received more rain, others have had bigger storms and a few areas in the world have experienced unusual droughts.

New York, the city that never sleeps, fell silent last week—schools were closed; bus and subway services were stopped; flights were canceled, and even the stock market closed for the first time since 1985. All the disorder was caused by one thing, the arrival of hurricane Sandy.
This big storm landed on Oct 29 on the US east coast and brought damaging winds, flooding, blackouts (停电) and heavy snow.
Sandy is one of the largest storms that have ever hit the US, according to the National Oceanic and Atmospheric Administration. By the afternoon of Nov1 (Beijing time), about 140 deaths were caused by the storm as it traveled across the Caribbean islands and into the US.
Unlike most hurricanes that happen during summer, Sandy was strengthened not only by warm ocean water, but also by the cold air coming from the northwest. Sandy’s power grew because of the difference in masses between the warm and wet air and cool and dry air. It became a kind of “super-storm”, the Guardian reported.
The flooding was particularly severe. Scientists said it was because Sandy’s arrival happened together with a full moon, which normally means higher-than-usual tides (潮水).
“The most worrying aspect of Sandy is the high tides,” Rhode Island Governor Lincoln Chafee told Reuters before the storm arrived. “With the full moon on Monday, with Sandy coming up the bay, we’re very concerned about flooding in our low-lying coastal areas.”
Apart from the power of Sandy itself, another reason why her arrival has caused so much damage is that its target area is crowded with big cities such as New York and Philadelphia. These urban areas are home to tens of millions of people. The flood, the snow and the blackout have brought the country’s financial and political centers to a stop.
“The size of this alone, affecting a heavily populated area, is history making.” Said Jeff Masters, a hurricane specialist.
