FRISCO — What until recently was a mostly academic discussion about sea level rise is starting to hit home — literally —as Americans watch devastating storms like Katrina, Irene and Sandy engulf cities and fundamentally alter the shape of coastal areas.

“What is very clear is, the ocean is rising and it’s going to keep rising for quite some time. The difference from last time is, now, there are a lot of people living on the coast,” said Margaret Davidson, acting director of NOAA’s Office of Ocean and Coastal Resource Management. Davidson’s powerpoint presentation is online here, and a video of her presentation should also be posted at the same place soon.

The consequences of rising sea level are likely to be enormous, given that the majority of the country’s population lives along coastlines, and those coastal cities generate a huge percentage of the country’s economic wealth.

“How do we begin to think about that? We’ve never had to think about relocating large populations,” Davidson said, addressing an audience of broadcast meteorologists and climate scientists during the annual Glen Gerberg Weather and Climate Summit in Breckenridge. Continue reading

New climate model pinpoints predictions down to the city level

By Summit Voice

SUMMIT COUNTY — As climate models become more sophisticated, researchers have started to fine-tune global warming impacts to the regional level, including more drought and water shortages expected in the Southwest, seasonal ice-free conditions in the Arctic, and hotter, wetter conditions in the Eastern U.S., according to a new University of Tennessee study.

The researchers, Joshua Fu, a civil and environmental engineering professor, and Yang Gao, a graduate research assistant, say heat waves will become more severe in most regions of the eastern United States and, that both the Northeast and Southeast will see a drastic increase in precipitation.
