Frankenstorms are fueled by global warming

Global Warming Raises Sea Levels, Alters Jet Stream, Makes Storms Stronger
SAN FRANCISCO— As America copes with the destruction caused by Hurricane Sandy, scientists with the Center for Biological Diversity are urging the Environmental Protection Agency to use the Clean Air Act to take emergency action against climate change. Global warming creates a “superstorm triple whammy” that helps turn nasty weather into a nightmare of killer winds and devastating storm surges.
“The terrifying truth is that America faces a future full of Frankenstorms,” said Shaye Wolf, Ph.D., the Center’s climate science director. “Climate change raises sea levels and supersizes storms. The threat of killer winds and crushing storm surges will grow by the year unless we get serious about tackling greenhouse gas pollution.”
Here’s how scientists say climate change feeds the superstorm triple whammy:
1. Global warming loads storms with more energy and more rainfall. A new study in the Proceedings of the National Academy of Sciences found that Katrina-magnitude Atlantic hurricanes have been twice as likely in warm years compared with cold years. In warm years hotter ocean temperatures add energy to storms and warmer air holds more moisture, causing storms to dump more rainfall. Global ocean temperatures hit their second-highest level on record in September, according to the National Oceanic and Atmospheric Administration.
2. Storm surge rides on higher sea levels, so more coastline floods during storms. In the northeastern United States, sea levels are rising three to four times faster than the global average, putting major U.S. cities at increased risk of flooding and storm surges, according to a June 2012 study in Nature Climate Change. The West Coast is not immune: Most of California could experience three or more feet of sea-level rise this century, heightening the risk of coastal flooding.
3. Melting sea ice and accelerating Arctic warming are causing changes in the jet stream that are bringing more extreme weather to the United States. Climate change in the Arctic is destabilizing the jet stream, causing bursts of colder air to drop down farther into the United States. In Sandy’s case, a collision with a cold front acted to turn the hurricane into a superstorm. Recent research, including studies by Georgia Institute of Technology and Rutgers University, has linked Arctic warming to increased risk of a variety of extreme weather events.
Deep and rapid greenhouse gas cuts are needed to reduce extreme weather risk. The Clean Air Act is America’s leading tool for curbing greenhouse gas pollution, and more than three dozen U.S. cities have joined the Center’s Clean Air Cities campaign urging the EPA to use the Clean Air Act to help reduce carbon in our atmosphere to no more than 350 parts per million, the level scientists say is needed to avoid catastrophic climate change.
The Center for Biological Diversity is a national, nonprofit conservation organization with more than 450,000 members and online activists dedicated to the protection of endangered species and wild places.

Here comes the snow City of Boulder warning
Oct 24th
City prepares for snowfall and reminds people to remove snow from sidewalks
Current weather forecasts indicate that an incoming storm may produce accumulated snow in Boulder beginning the night of Wednesday, Oct. 24, and continuing through Thursday, Oct. 25. The City of Boulder is preparing snow response crews in advance. Community members are asked to be mindful of the conditions, to prepare their vehicles as appropriate and to plan for extended commute times.
Snow Removal on City Streets
The city’s Public Works Department has snow crews on-call 24 hours a day, seven days a week to respond to changing weather conditions. During snowstorms, 16 plow trucks are active on Boulder’s streets. Six of the trucks distribute a liquid deicer, four spreader trucks distribute traction materials, and six trucks can distribute either material. Fifteen of the plow trucks drive predetermined routes while one “floater” truck responds to problem areas.
During the snowstorm, the city may spot-treat bridges and overpasses as needed to help reduce the buildup of ice and snow. Depending on the weather conditions, a liquid deicer may also be applied to streets and multi-use paths to continue melting the snowpack throughout the snowstorm. Spreader trucks will dispense a crystallized deicer for traction, where appropriate.
consistent with other Front Range communities, the city does not plow all residential streets since Boulder’s sunny climate typically melts most snow within a day or two and because residential plowing would increase costs by an estimated 200 percent. Plowing residential streets would also block driveways and cars parked on the streets. However, problem areas like particularly icy slopes, blocked storm drains or impassable sidewalks can be reported to the city for response. To report roadway or path problems, call the Street and Bikeway Maintenance Hotline at 303-413-7177.
Sidewalk Snow Removal
The Boulder Police Department is responsible for enforcing the city’s sidewalk snow removal ordinance. Property owners, tenants and landlords must clear their sidewalks within 24 hours after snow stops falling. Official snowfall reports are available on the National Weather Service website. Failure to remove snow from sidewalks before the 24-hour deadline may result in a summons and/or an abatement process. Abatement includes the use of a private snow removal contractor to clear the sidewalk. The property owner will be charged a $50 administrative fee, along with the contractor’s fee for removing the snow. To report a sidewalk snow violation, call Code Enforcement at 303-441-3333. Snow should be shoveled onto landscaping, not into the streets. Pushing snow into the streets creates hazards for bike commuters and pedestrians, and gutters clogged with snow may cause ice to form on the sidewalks.
The ICEBUSTERS program pairs residents who are physically unable to clear snow from their sidewalks with someone who can do the work for them. Seasonal and substitute volunteers are needed for this community program. To volunteer or learn more, please call 303-443-1933.
