The latest data confirm what a growing number of scientists have been saying for several years. The Earth’s climate is rapidly changing. According to a report from the Smithsonian Institution and several other U.S. agencies, global temperatures increased by about one degree Fahrenheit over the course of the last century, and will likely rise even more during this one. Scientists predict that unless greenhouse gas emissions are reduced greatly, temperatures in the United States will rise by about 5 to 10 degrees Fahrenheit on average in the next 100 years, an increase even larger than what’s predicted globally.
Such drastic temperature changes will cause a broad range of impacts. Sea levels will rise and it will flood coastal areas. Glaciers and polar ice packs will melt. Heat waves will be more frequent and more intense. Droughts and wildfires will occur more often. As habitat changes or is destroyed, species will be pushed to extinction.
To reduce all these bad situations the world will have to be much more careful about things. People can cut back on simple things like aerosol cans, driving your car (car pool) or turning down your heat in your house. All those things and many more help cause global warming. But to improve it, the entire world has to cut back. There may come a time in this world when there is not enough air to breathe or enough food to eat. Let us try to prevent that!
