Midday: Global warming
Posted at 10:55 AM on February 2, 2007 by Bill Wareham (2 Comments)
Two full hours on global warming coming up on Midday.
At 11 a.m, we'll take listener calls and on-line questions about the basics of global warming. Our studio guest is scientist Elizabeth Wilson, who teaches energy and environmental policy at the University of Minnesota's Humphrey Institute.
At noon, you'll hear highlights of the presentations about global warming from the big joint meeting of House and Senate committees, held in the Minnesota House Chambers earlier this week.
As an avid environmentalist, teacher, and graduate student- here in Duluth, MN- I am appreciative of this Midday Program on global warming and how prevelant it is in global society. I recently returned from Seoul, South Korea after Teaching English there and am amazed at the differences between Duluth (home) and Seoul- meaning air quality, slower pace of life, etc.....I am wondering what it will take for Americans to reduce their impact on the environment, to recycle, and to find alternative ways of living- via sustainability and community living centers..... And, as a woman, I don't think that I can bring children into this world - with the human costs of global warming...... I would rather fight to solve the problem. And, why is change so slow to come bye? Lake Superior needs to be restored, the water needs to stay here in the Great Lakes states, and Duluth is a great city to bike around in. Ditch the car and bike.
I really was surprised by Elizabeth's answer to my question: does the Earth receive the same amount of energy from the sun on a constant basis? Her answer: depends on your latitude and longitude and we receive on average 250 watts per sq meter.
The real answer is that yes the energy varies (see Milutin Milankovi) and that the Earth get about 1000 watts per sq meter as found in a Dept of Energy 20page report to Congress in 2002 regarding using Solar Energy in the SW United States.
