A new report says human-caused pollution is making the world a warmer place. From steamy summers to rising sea levels, the world is getting hotter and scientists believe humans are partly responsible. Every time we burn gasoline to operate our cars or coal to generate electricity in power plants, carbon dioxide and other gases are released into the atmosphere. These gases form a hazy blanket around the earth that trap heat into the atmosphere, causing temperatures to rise.
Many scientists say pollution from cars is causing global warming.
In many ways, a warmer world would mean big trouble in the future. Global warming would cause some ice at the North and South Poles to melt. Oceans would rise, possibly putting some parts of Florida and Louisiana underwater. Although these scientific findings are not new, they are making headlines this week because President Bush is expected to discuss global warming with 15 European leaders next week. The President asked a group of 11 top climate scientists to prepare the report before his trip.
