The many scientists behind the National Climate Assessment, released the day after Thanksgiving, have provided something of a price tag, says a Washington University in St. Louis expert on mitigation and sequestration.
“Thanks to this report, we can now weigh the cost of climate change versus the cost of mitigation,” said Daniel Giammar, the Walter E. Browne Professor of Environmental Engineering in the School of Engineering & Applied Science.
“We currently have three main ways to reduce the emission of carbon dioxide into the atmosphere,” Giammar said. “We can use more renewables, a shift we have been slowly making in the United States. We can transition from coal to natural gas, which helps,” he said, “though isn’t a long-term solution.
“Then there’s carbon capture and sequestration,” or capturing carbon and storing it in a way that keeps it from entering the atmosphere, where it would otherwise contribute to warming, he said.
