Warmer atmosphere means more moisture, more rain
FRISCO — After carefully reviewing data from hundreds of stream gauges, University of Iowa scientists say they’ve identified a clear trend of increasing floods during the past 50 years.
“It’s not that big floods are getting bigger, but that we have been experiencing a larger number of big floods,” said Gabriele Villarini, a civil and environmental engineer and corresponding author on the paper, published Feb. 9 in the advance online edition of the journal Nature Climate Change.

Study eyes flood ‘tipping’ points
FRISCO — Rising sea levels will subject many coastal areas in the U.S. to frequent flooding by the middle of the century, according to a new NOAA study aimed at identifying flood “tipping points.” By 2050, a majority of U.S. coastal areas are likely to be threatened by 30 or more days of flooding each year the study concluded.
The research was led by NOAA scientists William Sweet and Joseph Park and published this week in the American Geophysical Union’s online peer-reviewed journal Earth’s Future. Continue reading

Attribution studies still somewhat sketchy
Does global warming cause extreme weather?
FRISCO — A Stanford University climate researcher says that better modeling, advanced statistical analyses and a more robust set of observational climate data will help scientists under stand whether global warming is leading to more extreme weather events like floods, droughts and heat waves.
Such events appear to happening more frequently around the world, but because high-quality weather records go back only about 100 years, most scientists have been reluctant to say if global warming affected particular extreme events. Continue reading

High runoff taking a toll on roads

FRISCO — Spring runoff is starting to take a toll on high country roads, with a major washout reported along Montezuma Road and minor flooding in other areas, including a partial washout on the Meadow Creek trailhead road in Frisco.
East of Keystone, Summit County officials reported a 45-washout of Montezuma Road, leaving Montezuma residents withouth vehicular access. According to the county, the road is washed out 15-feet deep near the Peru Creek trailhead. Continue reading

New study outlines adaptation options
By Summit Voice
FRISCO —Europe needs to update its risk management strategy to adapt to the growing threat of floods, an international team of experts said this week, projecting that flood costs will climb dramatically during the next few decades.
By 2050, average annual flood-related costs could soar to €23.5 billion, up from the €4.9 billion in average annual losses for the 2000 to 2012 period, according to a new study published in the journal Nature Climate Change by researchers from the International Institute for Applied Systems Analysis and other European institutions.
Eying the widespread transnational threat, the team of economists and hydrologists advocated for restructuring pan-European funding mechanisms to better manage flood risks. Continue reading

Climate experts outline weather extremes across the U.S.
By Bob Berwyn
After years of persistent drought across big swaths of contiguous 48 states, the weather picture changed dramatically in 2012. Instead of dealing with parched ground, farmers in the Southeast weren’t able to harvest crops this summer because of standing water in the fields.
Mold and fungal diseases were reported across the region, particularly on crops such as corn, tomatoes and peanuts. The excess moisture has degraded the quality and flavor of many crops, including watermelons, tobacco, and peaches. Flooded soil has hampered the growth of cotton and corn, with damage from excess moisture expected to cost billions, The National Climatic Data Center reported this week in its July update.

New report recommends bolstering natural defenses, better long-range planning for coastal communities

SUMMIT COUNTY — Along with obvious threats like flooding, rising sea level is likely to affect the U.S. in more unexpected ways, including a decline in seafood quality and shifts in disease patterns, according to a new technical report released this week by the U.S. Geological Survey and NOAA.
The report emphasizes the need for increased coordination and planning to ensure U.S. coastal communities are resilient against the effects of climate change. Sea level rise and increases in extreme weather threaten the the sustainability of many existing coastal communities and natural resources, according to USGS researcher Virginia Burkett.
“An increase in the intensity of extreme weather events such as storms like Sandy and Katrina, coupled with sea-level rise and the effects of increased human development along the coasts, could affect the sustainability of many existing coastal communities and natural resources,” said Virginia Burkett of the U.S. Geological Survey and co-lead author of the report.
