From a story by Steve Cahalan in the La Crosse Tribune:
Explorer Will Steger of Ely, Minn., the fourth person ever to reach both poles, said he’s witnessed the effects of global warming in the Arctic and Antarctica.
Nations must act quickly to reduce carbon dioxide emissions and prevent global warming from causing catastrophe, he warned Wednesday during an Executive Energy Forum that Xcel Energy held at the Radisson Hotel for about 50 business leaders.
“I see global warming as a unifying issue in this country,” Steger told the group, saying new technologies to counter global warming will lead to job and economic growth.
“We need to get into technology, we need to get into ethanol, the wind, cars that get 80 miles per gallon, efficient light bulbs and so forth,” he said in an interview after his talk.
The U.S. Geological Survey said last month that two-thirds of the world’s polar bears are expected to be gone by 2050, including Alaska’s entire population, because of thinning sea ice from global warming in the Arctic. With the polar bears’ habitat “literally melting off,” Steger said he was motivated to speak out.
If left unchecked, global warming threatens drastic climate changes and other trouble due to higher sea levels, said J. Drake Hamilton, science policy director for Fresh Energy, a St. Paul-based nonprofit organization that says it promotes a clean, efficient and fair energy system.
“The economics of climate change are going to impact us in the future,” said Betsy Engelking, Xcel manager of resource planning and bidding. This must be taken into account when Xcel makes plans to address growing demand for electricity while minimizing effects on the environment, she said.
