The Latest on Global Warming
News story originally written on August 3, 2001
A recent study by scientists at the U.S. National Center for Atmospheric Research has 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 even dramatic policy changes designed to curb global warming would take a long time to really slow the temperature changes that are predicted.
