Writing for Quartz, meteorologist Eric Holthaus says that the super typhoon Haiyan about to hit the Philippines is the worst storm he has ever seen. With sustained winds of 190mph (305km/h) and staggering gusts of 230mph (370km/h), its “intensity has actually ticked slightly above the maximum to 8.1 on an 8.0 scale.” Updated: It broke 235mph. Videos of the impact added.
Holthaus says that Yolanda—its Filipino name—beats “Wilma (2005) in intensity by 5mph—that was the strongest storm ever in the Atlantic,” which makes it a member of the select club of Worst Storms Ever in the Planet. Only three other storms since 1969 have reached this intensity.
That’s certainly foreboding enough, but the humanitarian disaster that may Read more…
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…

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…
