Narrator: This is Science Today. Awareness about global warming has increased in recent months due to President Clinton's efforts to educate the public before an upcoming convention in Japan which will try to establish standards on emissions. Physicist Michael Wehner (WAY-ner) of the Lawrence Livermore National Laboratory, who's been working on a climate model of the atmosphere, says the most important thing is for the public to keep informed.
Wehner: Climate change, in my opinion, is going to happen and there's a lot of talk about what to do
Narrator: With global climate models improving by the year, Wehner says methods of prediction are getting better.
Wehner: The important thing is to be able to predict what's going to happen and then we can act on it. For instance, if the center of the continental land masses becomes much warmer and drier, one would want to change crops. Or if the sea level is predicted to rise in a global warming, low-lying areas would need to be protected.
