The more accurate version of this question would really be something like, "Why do some trees fall over in a storm while others stay standing?" The answer is more complex than a simple distinction between old, rotted, and weak vs. young, healthy, and strong. Instead, writes Mary Knudson at Scientific American blogs, trees fall because of their size, their species, and even the history of the human communities around them.
“Trees most at risk are those whose environment has recently changed (say in the last 5 – 10 years),” Smith says. When trees that were living in the midst of a forest lose the protection of a rim of trees and become stand-alones in new housing lots or become the edge trees of the forest, they are made more vulnerable to strong weather elements such as wind.
They also lose the physical protection of surrounding trees that had kept them from bending very far and breaking. Land clearing may wound a tree’s trunk or roots, “providing an opportunity for infection by wood decay fungi. Decay usually proceeds slowly, but can be significant 5-10 years after basal or root injury.” What humans do to the ground around trees — compacting soil, changing gradation and drainage “can kill roots and increase infection,” Smith warns.
Short version: yes, but it's not easy. "To win, New York ratepayers have to show that their power company was not just slow or inefficient. Instead, Kreppein said, under a 1985 New York Court of Appeals ruling called Strauss v. Belle Realty, electric company customers must establish that the utility was grossly negligent — that its conduct was way outside the bounds of reasonableness." Alison Frankel at Reuters. — Xeni
As you can imagine, the situation here in New York is dire, what with the still-large amount of people who have yet to even get their power back. But Staten Island (and the Rockaways, and Long Beach, most of the south shore, not to mention Red Hook, parts of New Jersey... you get the idea) was hit particularly hard, with entire houses being destroyed. According to Gothamist, 5,200 residents of the borough have filed for FEMA housing, but Gov. Andrew Cuomo is considering one location specifically designed to provide a large amount of people (about 900) heat, food, and temporary shelter: Arthur Kill Correctional Facility. Yup. A prison. That's been shut down for about a year. Sound familiar? Like the plot of the third season of The Walking Dead? Living in an abandoned prison makes sense, of course -- for all the same reasons it made sense as an option during a fictional zombie apocalypse. Wow, things are that bad? Some of those thousands of displaced residents might say it is. But it's just an idea at the moment. (via Gothamist) — Jamie
The ocean has not always met the land at the same place it does today. In fact, during Ice Ages, when more of Earth's water was trapped in glaciers, large swaths of what is now the Atlantic Ocean were dry ground. Things died there. In some cases, they fossilized. And when a big storm like Sandy hits, those bits of fossils can get broken out of the stones they're embedded in and washed up on our modern shores.
In this video, paleontologist Carl Mehling wanders Long Island's Rockaway Beach looking for fossils unearthed by Superstorm Sandy. It's a great video — and a handy "how to" as Mehling explains the basics of beach-based fossil hunting and how to tell the really old dead things from the simply dead things.
Everyone, just shut up and give them all your money: Louis C.K., who hosted Saturday Night Live in New York City in the midst of Sandy's chaos, and Long Island native Jerry Seinfeld are both planning separate comedy shows to benefit storm victims. Louis C.K.'s two shows will take place on Staten Island, one of the hardest hit areas of New York, on November 17 at St. George Theatre. Tickets are currently being sold through his site, and he urges everyone to ignore any possible scalpers.
Seinfeld, who was served lunch by my very own grandmother when he attended Massapequa High School, will be adding an additional Long Island show for December 19 at the NYCB Theatre in Westbury as part of his December tour. All proceeds will benefit Sandy victims, as well as the earnings from last night's show at Brooklyn College and the newly-scheduled December 6 show at St. George Theatre.
While it's not exactly a surprise that two comedians with incredibly strong ties to New York would want to do something to give back, it's still always nice to report that celebrities have hearts. In case you needed a reminder.
A Q&A piece on the National Oceanic and Atmospheric Administration begins with this incredibly disconcerting sentence: "During each hurricane season, there always appear suggestions that one should simply use nuclear weapons to try and destroy the storms."
Really? Seriously, America?
Anyway, the entire piece ends up being pretty fascinating, as research meteorologist Chris Landsea explains why nuking a hurricane would be a bad idea ... besides, you know, the obvious reasons.
... an explosive, even a nuclear explosive, produces a shock wave, or pulse of high pressure, that propagates away from the site of the explosion somewhat faster than the speed of sound. Such an event doesn't raise the barometric pressure after the shock has passed because barometric pressure in the atmosphere reflects the weight of the air above the ground. For normal atmospheric pressure, there are about ten metric tons (1000 kilograms per ton) of air bearing down on each square meter of surface. In the strongest hurricanes there are nine. To change a Category 5 hurricane into a Category 2 hurricane you would have to add about a half ton of air for each square meter inside the eye, or a total of a bit more than half a billion (500,000,000) tons for a 20 km radius eye. It's difficult to envision a practical way of moving that much air around.
Attacking weak tropical waves or depressions before they have a chance to grow into hurricanes isn't promising either. About 80 of these disturbances form every year in the Atlantic basin, but only about 5 become hurricanes in a typical year. There is no way to tell in advance which ones will develop. If the energy released in a tropical disturbance were only 10% of that released in a hurricane, it's still a lot of power, so that the hurricane police would need to dim the whole world's lights many times a year.
“Scientists and engineers were saying years before Katrina happened, ‘Hey, it’s going to happen, folks. Stop putting your head in the sand.” —Malcolm Bowman, professor of oceanography at the State University at Stony Brook. In 2009, he and other experts convened at a meeting in NYC of the American Society of Civil Engineers, and issued warnings that surge barriers or tide gates would help protect.

In an Army Corps of Engineers press release, details on the astounding rate at which workers are draining water from New York's subway and transit tunnels: "To date, the USACE has used about 50 pumps of various sizes to remove 64 million gallons of water from the New York City mass transit system. Operations are ongoing at six sites, with pumps removing about 116,000 gallons per minute. The 696,000 gallons the pumps are draining each minute exceeds the amount of water in one Olympic-size swimming pool (660,000 gallons). There were roughly 600 million gallons in the tunnels when pumping operations began on Thursday, Nov. 1." (via Noah Shachtman).— Xeni
Yesterday, I got to have a great conversation on Minnesota Public Radio's The Daily Circuit. Host Tom Webber and I spent a good 45 minutes talking about Hurricane Sandy, climate change, and why it's so hard to talk about the connections between the two in an easily digestible, sound-bite format. In the meantime, he might have gotten some good sound bites out of me.
Backup generators exist anonymously. They are metal boxes, squirreled away on a roof or near a loading dock. You are meant to not see them. The point is that they are there when you need them and, the rest of the time, they do their best to be unobtrusive.
The problem is that this very job description makes it more likely that your emergency generator won't work in an emergency.
On Monday, New York University's Langone Medical Center lost power during Hurricane Sandy, and ended up having to evacuate 215 patients when the generator that was supposed to keep its charges alive and its critical systems running failed to turn on. Across the United States there are about 12 million backup generators. Most only operate during blackouts — times when a hospital, or a laboratory, or a bank, needs electricity and can't get it from the larger electric grid.
But backup generators aren't 100% reliable. In fact, they won't work something like 20%-to-30% of the time, said Arshad Mansoor, Senior Vice President for Research & Development with the Electric Power Research Institute. The bad news is that there's only so much you can do to improve on that failure rate. The good news: There are solutions that could help keep a hospital up and running in an emergency, even if the emergency power system doesn't work.
