The names for the 2009 hurricanes were announced a few days ago by the National Hurricane Center (NHC). The NHC has a list of names they draw from, that reuses names every six years or so, but if a storm is particularly bad a name will be retired. There are no "Q" or "U" names and they go alphabetically so when they get to Danny you'll know that's the fourth of the season. The names for 2009 are:

Ana, Bill, Claudette, Danny, Erika, Fred, Grace, Henri, Ida, Joaquin, Kate, Larry, Mindy, Nicholas, Odette, Pete, Rose, Sam, Teresa, Victor and Wanda.

(Interesting the names "Pete" and "Rose" are in succession.)

So far this year we're up to Claudette. Ana is old news already with the National Hurricane Center announcing yesterday that the storm had weakened so much they were no longer tracking it. Claudette is also weakening, but it had the distinction of being the first tropical system to reach land yet this season. Third in line is Bill, who has already become a category 3 hurricane. Follow Bill’s progress here.

Retired hurricane names.

Hundreds of the city's trees were knocked down by the storm. I was at the Science Museum for a meeting when the warning sirens sounded so on the way home I drove into the affected area to see for myself. Crushed car in South Minneapolis

I just happened to have a pocket camera with me (I just bought it over the weekend) so I took some photos of the damage in one small area of South Minneapolis near the intersection of Portland Avenue South and East 43rd Street (I used to live near the neighborhood). Because the storm came on without any warning and much of it under the cover of heavy downpour, the weather service's usual storm spotters weren't in place to report on conditions or damage. Investigators are on site today to determine if the culprit was a small tornado (or tornadoes) or straight line winds. The last tornado to go through Minneapolis was back on June 14, 1981. I remember that one well.Another unfortunate victim of the freak Minneapolis storm

I don’t live in New York, and have only been there a couple of times. But the last time I was there I was able to spend a few minutes in wonderful Central Park, so this article caught my eye.

According to officials at the Department of Parks and Recreation and the Central Park Conservancy (who manage the park), over 100 trees were toppled in what they called the most severe destruction the park has seen in at least 30 years.

Check out these flickr images of the damage. Do you live in New York and/or have you seen the damage? Tell us about it by commenting below!

Six states set records for coldest July ever recorded

Iowa, Illinois, Indiana, Ohio, West Virginia and Pennsylvania set all time records for cold in July while Michigan, Wisconsin, Missouri and Kentucky had their 2nd-coldest July ever recorded.
What is really weird is that in spite of this record cold

The global average went from normal in June to the second-hottest July on record. USA Today

Where was it hotter than normal?

For the global average temperatures to reach near record highs in spite of the central USA's record cold, it must have been really hot somewhere. If you look at this map you will see that the hotter than normal areas are near the South Pole.

Pack your bags, Buzzketeers, because you don’t want to be the last person to make it to the world’s newest, creepiest continent. (Don’t worry, Australia, I’m not talking about you.)

Trashlantis! The new frontier! The Texas-sized plastic layer floating in the middle of the Pacific Ocean! Why would you not want to go there? The answer, of course, is that you wouldn’t not want to go there… ever!

Yet another scientific expedition is on its way to the fabled plastic continent. But while the last group of researchers mentioned on Buzz was at least partially motivated by the potential to turn Trashlantis back into some more useful hydrocarbons, it looks like these folks are more interested in seeing how the plastic is affecting sea life.

The Yahoo article linked to above sums up the expedition with:

”The expedition will study how much debris -- mostly tiny plastic fragments -- is collecting in an expanse of sea known as the North Pacific Ocean Gyre, how that material is distributed and how it affects marine life.”

I’m guessing what they’re getting at has to do with how plastic affects very very small organisms as it photodegrades. We understand how chunks of plastic in the ocean are no good for larger animals—marine life can choke on them, or fill their stomachs with trash—but the problem goes further than that. See, eventually those larger pieces of plastic start to photodegrade. (That means they get broken down by the energy in sunlight.) But photodegredation doesn’t seem to actually get rid of the plastic, it just breaks it into increasingly smaller pieces. When a plastic bag turns into a million little tiny chunks, it no longer poses a risk for, say, a sea gull choking on it. But smaller organisms are still likely to gobble some up, and if they can eat anything bigger than they can poop (it happens), they’re in a lot of trouble. And when small organisms die off, so do the slightly larger creatures that eat them, and the larger creatures that eat them, and so on. (You remember this from grade school.) So how will Trashlantis fit into this plasticky food-path?

And then there’s the huge real estate potential for Trashlantis. So get there now.

Green energy? What about trying a little blue energy for a change? Blue seems just as wholesome and non-threatening, right?

In a similar vane to my last post on algae the geniuses of the world have come up with another truly brilliant "why didn't I think of that" kind of idea. It seems to make so much sense! It's so big ... and powerful ... and blue ...

Engineers at Blue Energy have developed, with support from the Army Corps of Engineers a turbine for the ocean. No no, not a wind turbine ON the ocean (my mom just made that mistake) but an underwater turbine that will harness the powerful ocean currents to create possibly the most sustainable energy source we know of!

Here is what we know: Water turbines will be placed in the Gulf Stream near Florida and they will work much like land wind turbines (using a rotater blade, which when made to spin by wind or water, creates energy!).

There is still a considerable amount of work to do before water turbines can be utilized. Frederick Driscoll, director of Florida Atlantic University's Center of Excellence in Ocean Energy Technology strives to be realistic about the future of water turbines. A resource assessment of the Gulf Stream is underway to help understand exactly how much energy can be safely extracted from the ocean, where exactly it should be extracted from and how to get the energy safely and efficiently to our homes without disrupting the ocean environment. So much to think about!

Florida is the fourth largest state in the U.S. and the third largest consumer of energy. They are in dire need of a new energy source as many experts insist that Florida is on the brink of a very serious energy crisis. Much still needs to be done in the way of turbine technology in order to move ahead with incorperating them into the fleet of renewable energy sources. This past spring four acoustic Doppler current profilers were lauched off the coast of Florida to gather information about the currents, mainly to learn about the speed of the ocean currents. Ocean energy may become the crown jewel of the fleet.

Much truth is spoken in jest.

We've all heard about global warming, the undeniable fact that the Earth's temperatures rose (dramatically / sharply / noticeably – take your pick) from 1980 to 1998. (We've heard considerably less about the equally undeniable fact that from 1999 to present temperatures have held steady or even dropped, but never mind.)

We've all heard that carbon dioxide, released into the atmosphere when we burn coal, gas or other fossil fuels, is the (only / primary / most important) source of the warming. (The Earth also warmed during Roman and Medieval times, when fossil fuel consumption was vanishingly small. But never mind.)

And we've all heard how this warming is going to bring about floods, drought, storms, extinctions and other ecological disasters if we don't reduce out carbon output by (the end of the century / 2020 / tomorrow afternoon).

Those first two points can be tested through observation and experiment. The last one cannot. It's a prediction about the future, and you cannot observe something that hasn't happened yet. But you can always bolster your position by accurately predicting the past.

Now, that may seem like a waste of time – I mean, it's the past. We know what happened. But that's what makes it such a great laboratory. Y'see, scientific predictions are based on models. Scientists take all those observations and experiments, put them in a computer, and see where the trends lead. You can test the model by taking observations from some point in the past, crunching the numbers, and seeing if the results match what we know happened next.

And that's exactly what Richard Zeebe, James Zachos and Gerald Dickens did. In an online article published by the journal Nature Geoscience, these three scientists took the model used by climate researchers to predict future global warming and applied it to an episode of past global warming. Specifically, they looked at a well-studied period 55 million years ago when the Earth's temperature rose dramatically. They plugged the data from that warming into the model used to predict current warming, and they found....

It didn't work. The climate models being used today were unable to duplicate known conditions from the past. They weren't even close – the results were off by about 50%.

Move over, old, lame bio-fuels!

Algae! The wondrous plants that can grow easily in controlled conditions and whose needs are very basic for rapid growth is now being tested for use in bio-fuels. ExxonMobil, looking to expand and diversify their alternative fuel options will team up with Venter's Synthetic Genomics Inc. to conduct research on different types of algae to test their effectiveness as biofuels.

The so-called "first generation" bio-fuels caused problems globally when the price of corn (for corn ethanol) sky rocketed when it was being used for food and fuel . Though a small percent of corn (or other) ethanol is added to gasoline, it still has a huge effect on the market, and is therefore not the best long term solution to eliminating our addiction to oil.

The Future?: Someday...someday. Let's keep 'em crossed for a day when all houses are like this!

Many view bio-fuels as only a transitionary solution to the oil problem, hoping that a sustainable energy type (like solar or wind) may soon be widely available. Algae if successful as a bio fuel, it may be used for a longer period than the "first-generation" bio fuels because of how fast it can grow and how easy it can be to care for. It also isn't used for much else, not like corn anyway. Engineers are hoping to develop artificial environments for algae to grow in knowing that this is the only way to produce enough of the green slime to sustain our needs.

It is encouraging, in some ways, that a big business like ExxonMobil is getting involved because research will not be short funded. If there is a will, there is some green slime that can't wait to get in your car!

Ho-ly spit.

Zo-mg.

We are in deep trouble, friends, enemies and Buzzketeers.

Screw rising sea levels. Nuts to dwindling glacier-based freshwater reserves. Forget desertification. The real danger of global warming we’ve known about since 1958 and we’ve done nothing to prevent it. In our arrogance, we thought we’d be safe forever, but now the chickens have come home to roost. And they’re roosting hard.

Is it possible that you don’t know what I’m talking about yet?

Well, let me explain it to you in a roundabout way.

Remember being a kid in 1958, sitting in your home entertainment room, petting your chinchilla in the dark (not a euphemism), and eating a box of Gushers as you watched your Blu-ray of Steve McQueen’s The Blob? Remember how you felt when that little piece of space goo started to eat that old dude’s hand? Those Gushers burned like the blob’s acid touch, no doubt. And remember when you realized that no amount of hot lead was going to stop the blob, because, duh, why would bullets hurt space goo? You probably squeezed your poor chinchilla to death in your anxiety. Do you recall the little pinprick of hope you felt at the blob’s response to a blast from the CO2 filled fire extinguisher, and the final surge of relief as they crated the awful thing to the arctic, where it could be kept in safety… JUST SO LONG AS THE %@$##$%ING ARCTIC STAYS COLD… QUESTION MARK????!!!!!!!!!

If your chinchilla wasn’t dead already, it didn’t stand a chance at that point, because you were convulsively squeezing everything within reach, and vomiting half-digested Gushers all over your parents’ modern Scandinavian furniture. But no, soothes your nanny, as she strokes your hair and gently clears the Gushers from your airway, that could never happen. It’s the arctic she says, and, standing in the lit doorway behind her, your personal chef nods reassuringly. That’s why they call it “the arctic,” he says in his heavy Japanese accent. Your normal childhood is safe from a life of constant monster threat.

Or so you thought. It’s fifty years later, the arctic is melting, and, in many respects, you’re still a child. And the blob is free.

So far the number of humans-dissolved-alive remains at or near zero, but I expect this figure to skyrocket any day now, as the blob has been seen off the northern coast of Alaska.

The blob has been observed floating in dark, gooey looking mats on the surface of the ocean. The strands of goo are reported to be up to 12 miles long.

What you’re trying to convince yourself, I’m sure, is that this is no blob, but just another harmless oil spill. Wrong-o, says the local coastguard.

“It's certainly biological,” a coastguard petty officer reports. “It's definitely not an oil product of any kind. It has no characteristics of an oil, or a hazardous substance, for that matter.” The smell and composition, he says, suggest that it’s some natural substance, but it’s nothing that any of the locals remember seeing before. But they need only to return to their home theaters, and I’m sure they’ll recognize the substance in no time.

The substance is dark, hangs off the ice when they come in contact, and appears to be “hairy” when examined closely. “It kind of has an odor,” explained one of the locals on the goo expedition, “I can't describe it.” Well, I’ll describe the smell for you: fear.

Jellyfish have been seen tangled up in the blob, and one local turned in the remains of a dead goose, “just bones and feathers,” that had supposedly been found in the goo.

Samples of the blob were brought to Anchorage for analysis. Waste of time, if you ask me. The coastguard pilots that helped retrieve the sample are pretty certain it’s some kind of algae, but that’s what the military would say. It’s the blob.

Hide yourselves. Save your game frequently. Cherish what you remember of “normal life,” because it’s all about to change.

Did you know that the web page that you are staring at right now can produce as much CO2 as an SUV? Well, not science buzz itself but, the internet as a whole is a major contributer to the greenhouse gas, equaling the amount produced by the entire aviation industry. When you think about it, its not as amazing of a fact as it first appears to be. Just imagine the amount of electricity that is used to power all of the computers used in businesses and homes. Add to that the real culprit, all of the servers in data centers that store pictures, videos, and websites.

The data centers run 24/7Data Center

saving and processing information for internet users around the world. The amount of energy needed to run the servers is large but that is not the only consumer of electricity. The cooling systems for the rows and rows of buzzing machines eat electrons like popcorn. All of this electricity needs to come from somewhere and that is where the CO2 comes into play. Its the coal burning plants that add the gases to the environment.

Making more energy efficient cooling systems, better software, and using recycled water are some of the steps companies have made to create a greener internet. Although it is hard to measure how much CO2 each internet action adds and a direct comparison to cars is not available, this is something to think about when watching the latest youtube video. Its not only your computer you're powering.
