Cities on the United States east coast are “sitting ducks” for the next big storm because of the destruction wrought by Hurricane Sandy, one of Barack Obama’s top scientists warned on Tuesday.
Marcia McNutt, who last week announced her resignation as director of the U.S. Geological Survey, told a conference that Sandy had left coastal communities dangerously exposed to future storms of any size.

“Superstorm Sandy was a threshold for the north-east and we have already crossed it,” McNutt told the National Council for Science and the Environment conference in Washington. “For the next storm, not even a super storm, even a run-of-the-mill nor’easter, the amount of breaches and the amount of coastal Read more…
The chances that a 15-inch rainfall might hit Central Texas in any given year have long been about 1-in-1,000. But with the warming of air that scientists expect over the century, some predict those chances might jump to 1-in-50.Kerry Emanuel, a prominent Massachusetts Institute of Technology meteorology professor, will lecture on the topic in Austin on Tuesday. The talk, titled “Hurricanes in the Gulf of Mexico: The History and Future of the Texas Coast,” is free and open to the public, part of the University of Texas’ Hot Science-Cool Talks series.
“We expect hurricane-related rainfall is going to get worse over next 100 years,” Emanuel said in an interview.
While that news might seem welcome in drought-stricken Central Texas — especially since moister, hurricane rain-saturated soils are likely to Read more…
On CBS This Morning on Thursday, Kaku discussed 2012′s “wacky weather” and how global warming, which creates more energy circulating on the planet, exacerbates destructive tornadoes, storms, hurricanes and even forest fires.
“You look at the weather patterns over the last year, and they all seem wild, extreme. What was driving that?” asked anchor Rebecca Jarvis.
“Well, when you look outside you say, ‘The weather’s on steroids,’” Kaku said. “But there’s no single aha moment where you can say, ‘Aha, this is what’s driving the whole thing.’ But what you can say is that the Earth is heating up. Which means more moisture going into Read more…
An international study led by CSIRO oceanographer Dr Wenju Cai has identified that global warming is causing shifts in the rain band of the South Pacific Convergence Zone causing an increase in extreme weather across the island nation states of the South Pacific. The result of the movement causes drought and higher prevalence of forest fire in some areas while other islands experience extreme floods and increased frequency of tropical cyclones.
The South Pacific Convergence Zone is the important rainband that stretches from the equatorial western Pacific southeastward toward French Polynesia. When the rainband moves northward, extreme climate events are induced. “Here we show that greenhouse warming Read more…

Potential Impact This Year
Predicting exactly where storms will make landfall in the U.S. would be extremely difficult, but there are some indications of areas where storms may brew and coasts that may be vulnerable based on Read more…

So-called ‘storms of the century’ like last August’s Hurricane Irene could become almost commonplace, thanks to climate change.
A team from MIT and Princeton University says that such storms could make landfall far more frequently, causing powerful, devastating storm surges every three to 20 years.
The group simulated tens of thousands of storms under different climate conditions, and concluded that the sort of severe floods which now hit every five hundred years or so could, with climate change, start happening once every 25 to 240 years.
MIT postdoc Ning Lin says that planners should take the findings into account when designing seawalls and other protective structures.
“When you design your buildings or dams or structures on the coast, you have to know how high your seawall has to be,” Lin says. “You have to decide whether to build a seawall to prevent being flooded every 20 years.”
To simulate present and future storm activity, using New York City as a case study, the researchers combined four Read more…
Every hurricane season, climate scientists are asked how climate change is impacting hurricanes.
The short answer is that global warming makes the ocean warmer and increases sea surface temperatures, which can make hurricanes stronger. But several factors, including differences in wind speed and direction, can break up hurricanes. Many future projections show a decrease in the frequency of all hurricanes globally, but a higher chance of intense hurricanes forming when they do occur. The changing nature of hurricanes in a warmer world remains an active area of research.
In any case, focusing on climate change and hurricanes can obscure the consequences of less sensational climate-related threats to America’s coasts, including sea-level rise and more intense precipitation. Further, extreme Read more…
Astronaut Ron Garan tweeted this picture of Hurricane Irene from the International Space Station (NASA)The city is planning to shut down the entire transportation system on Saturday in anticipation of Hurricane Irene‘s arrival, officials revealed Thursday.
A mandatory evacuation of all nursing homes in flood-prone areas of the city was also ordered Thursday.
The monster storm is expected hit New York as a Category 1 storm sometime Sunday, barreling in with winds of 90 miles-per-hour and torrential rains.
Mayor Bloomberg said Thursday that it was “very conceivable” that he will order a mandatory evacuation of all low-lying areas of the city by Saturday.
“The storm is predicted to be very dangerous,” the mayor said.
“A stronger tropical wave now over the eastern North Atlantic might be a feature to watch during the next week or so.”While Bret is now pushing out to sea and remains no threat to the mainland U.S., indications continue to point toward a busy August and September as far as hurricanes are concerned.
A sizable tropical wave has rolled westward, off the coast of Africa, and bears watching as it cruises along through Antilles waters this weekend.
It is still a little early to expect much from the Cape Verde area, but one of the tropical waves could help to breed a tropical cyclone in the southwestern part of the Atlantic Basin by next week.
According to Tropical Weather and Hurricane Expert Meteorologist Dan Kottlowski, “A stronger tropical wave now over the Read more…
Every year extraordinary weather events rock the Earth. Records that have stood centuries are broken. Great floods, droughts, and storms affect millions of people, and truly exceptional weather events unprecedented in human history may occur. But the wild roller-coaster ride of incredible weather events during 2010, in my mind, makes that year the planet’s most extraordinary year for extreme weather since reliable global upper-air data began in the late 1940s. Never in my 30 years as a meteorologist have I witnessed a year like 2010–the astonishing number of weather disasters and unprecedented wild swings in Earth’s atmospheric circulation were like nothing I’ve seen. The pace of incredible extreme weather events in the U.S. over the past few months have kept me so busy that I’ve been unable to write-up a retrospective look at the weather events of 2010. But I’ve finally managed to finish, so fasten Read more…
