What Is Global Warming? Global warming refers to an
average increase in the Earth's temperature, which in
turn causes changes in climate. A warmer Earth may
lead to changes in rainfall patterns, a rise in sea level,
and a wide range of impacts on plants, wildlife, and
humans. When scientists talk about the issue of climate
change, their concern is about global warming caused
by human activities.
Signs of the early damage from warming already are appearing, according to a growing number of scientists and environmentalists. "There's likely going to be an increase in droughts and floods," says Stephen H. Schneider, climatologist and professor at Stanford University. "We're just beginning to show that emerging," he adds, in the form of more intense, destructive and deadly storms.
"You can never say with any one storm, 'We caused that,'" says Schneider. "But you can also never say with any one storm, 'We did not cause that.'"
Unchecked, continued climate change could mean big lifestyle changes in the next 30 years to 50 years. And it could also mean that life for your children and grandchildren will be more difficult and more expensive.
