The Latest on Global Warming
News story originally written on August 3, 2001
Recently, scientists at the U.S. National Center for Atmospheric Research have shown that there is a 90% chance that global
temperatures will rise 3-9 degrees Fahrenheit over the next 100 years. This is a big jump over the increase that was observed over the last 100 years, which was only about 1 degree. In the near future, the study predicts that average global temperatures will rise 1-2 degrees in the next 30 years.
The scientists say that whether or not these predictions actually come true or not depends on how involved the Earth's population gets in preserving its climates. They also caution that trying to stop global warming will be a slow process and will take long-term commitments from the countries and people on Earth.
