“But these increases in wildfires could totally disrupt our efforts to clean the air. Last weekend there was an area the size of some states in the eastern U.S. blanketed with unhealthy air over California and Nevada. And, we call this increase in smoke an important climate penalty on air quality.”
That penalty would be air that is two times as smoky as it is today. Ms. Mickley says these estimates suggest the need for better forest management. And, she adds, they send a warning sign to lawmakers and the public to reduce fossil fuel emissions that many scientists believe are warming the planet.
A report on the study will appear next month in the journal Atmospheric Environment. I’m Steve Ember.
A Scientist Who Gets Very, Very Close to a Tornado
Weather experts are able to predict bad weather better than ever before thanks to satellites, high-altitude balloons and radar stations. But for many years these experts have incorrectly predicted tornado formation giving false warnings about 75 percent of the time.
So, scientists are working to improve their tornado predictions.
­­­­­­­­­­­­­­June Simms reports.
Doppler is a type of radar that identifies weather conditions based on the flow and speed of objects through the air.
Scientist Joshua Wurman was the first to put Doppler radar equipment on a vehicle and drive it into the path of a tornado.
