Professor David G. Long presented the Karl G. Maeser Distinguished Faculty Lecture on "Microwaves, Icebergs, and Global Warming" on 27 Jan 2009. The full lecture is available for viewing on the web at URL http://byubnew.byu.edu/talks/Talk.aspx?id=2994. In his talk he discussed the research he and his students have done in microwave remote sensing of land use, icebergs, sea ice, and Greenland. Describing the Earth's climate system in general terms he related sea ice formation to global circulation and climate. He showed how greenhouse gases affect energy absorption in the atmosphere and discussed how the recent increase in greenhouse gases is causing a rise in global temperature. He urged students to protect the environment, "Even with the doubt and uncertainty about climate change, things that reduce greenhouse gases generally have the effect of protecting and preserving the environment," he said. "By wise and efficient resource use, we can save both our money and the planet." He concluded by saying that ""It has been suggested that it is arrogant to think that humans could adversely affect the earth. I believe the reverse is true: my work in remote sensing has helped me realize that we are affecting the planet, including climate."
