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.

When it comes to hard, noisy traveling, we’ve found that sometimes we’d rather read about it than actually go. Here are some bestsellers for armchair travelers.
The Station by Robert Byron. In 1928, the 22-year-old man made a journey to Mount Athos, resulting in one of the best travel books ever written, matched only by Byron’s own, much more famous The Road to Osciana.
In Darkest Africa by Henry Monton Stanley. It’s about his great efforts to save an unlucky German doctor Eduard Schnitzer, who had no desire to be rescued at all.
A Traveler’s Alphabet: Partial Memoirs by Sir Steven Runciman. A to Z and around the world. He provides priceless information of long-gone princesses, priests, and places.
South: A Memoir of the Endurance Voyage by Sir Ernest Shackleton. As the planet started the global war, Shackleton and his brave group of explorers made an unsuccessful but heroic journey to cross Antarctica from 1914 to 1917.
The Michelin Red Guide: France 2005 Reading through this final listing of all the nice hotels and wonderful restaurants in France is better than going there, listening to Chirac talk about the poisonous American culture, and spending the price of this book for a tiny cup of tea and a cookie the size of your thumb.
The Past Is a Foreign Country by David Lowenthal. This great book of an armchair exploration tells us what has happened in the past and shows the relationship between us and the past travelers.
