100,000 Electric Cars on the Road

Electric cars and special parking spots (this one is at
Google Headquarters) are becoming more common
on the American landscape.  Click for photo credit.
According to Grist, there are now more than 100,000 electric cars on the road in America.  The technology for developing the car was in part supported by loans from the U.S. Government.  Tesla, one of the leading electric car companies, has paid off its loan it received from the Federal Government under President G.W. Bush, indicating that they may have found the sweet spot between new technology and profitability.

Tesla makes beautiful cars that are on par with some of the nicest ones out there.  The range of their cars is well over 200 miles, making them suitable for most urban and suburban commuters.

The infrastructure for electric cars is increasing as well.  Many workplaces are putting in charging stations and offering parking incentives for those driving electric vehicles.

Passing the 100,000 threshold requires our society to take the electric car seriously.  I predict that there will be 1,000,000 electric cars on the road in 5 years.  Once things like this take off, they boom very quickly.

Historic Tornado Map of the US

Yesterday's deadly tornado outbreak in Oklahoma was a stunning display of nature's force.  The U.S. is home to the world's greatest concentrations of tornadoes.  No place else on the earth experiences the number or intensity of these unusual weather features.

Although they can happen anywhere in the country, the Great Plans, Midwest, and the South experience the greatest concentrations of tornadoes.

Take a look at he map below from NOAA.  It shows the location and track of tornadoes from the 50's to 2011 in the lower 48 states. You will notice that there are few areas of Oklahoma that haven't been impacted by tornadoes over the last 60 years.

NOAA has more interesting tornado maps and figures here.

When Tragedy Strikes a Campus

Click for photo credit.
Probably every teacher out there reading this who has been in the business for some time has had death visit their student body.  I can recall several sad events over the years.  Death can suddenly cut short the life of a young person with great talent and promise.

On Friday, death came again.  All of us on the Hofstra Campus learned of the shooting of one of our students, Andrea Rebello, in a botched home invasion near campus.  It was the last day of finals.  

I didn't know Andrea, but I, like many, was touched by the tragedy.  Today at graduation, a moment of silence was held for her and all of the students, faculty, and administrators wore white ribbons in her memory.  My condolences, and I am sure the condolences of all of the Hofstra family, go out to Andrea's family and friends.  I am certain she was a wonderful person and a joy to know.

It is always shocking when violence happens near campuses.  Most university neighborhoods are rather safe.  The neighborhood around Hofstra has had some issues, but nothing out of the ordinary compared with other campuses. 

At this morning's graduation I saw some of the administrative team at Hofstra who were obviously deeply distressed by the tragedy.  They are good people who have been working on a number of issues that normally would be celebratory, particularly graduation and the entrance of the new freshman class.  Today they did an excellent job creating a moving and positive graduation ceremony at a difficult time for our university.  They hit the right tones of grief, while recognizing the need to celebrate the Class of 2013.

So, when tragedy strikes at graduation time, it is important to grieve, but remember those who need to be recognized for their accomplishments.  But, we will not forget Andrea.

So in this midst of the emotion of joy through the tears, I was happy to see some of the Geology, Environment, and Sustainability majors  of the Class of 2013 graduate along with the students who earned the first minors in our new program in Sustainability (the first majors will graduate next year).  The Hofstra student body is well above average by any measure and these students ARE going to make our world a better place.

The best legacy we can all leave is one that gives hope to future generations.  Our students give me tremendous hope.  The present generation of college graduates is one of the smartest I've ever seen.  They have a commitment to not only themselves and their families, but to each other and the broader community in which they live.  There is no reason to fear the future.

The European Environmental Bureau's Musical Evaluation of Rio +20

I've been doing quite a bit of reading lately about various international sustainability plans.  The reading is fascinating, but can be a bit dry.  Every once in a while, one runs into something rather remarkable among all of the policy literature.  So, today, I give you a musical review by the European Environmental Bureau of the Rio + 20 conference.  If you are not sure what Rio +20 is all about, click here.

New material for Co2 capture discovered

Getting CO2 out of the air before it enters the atmosphere from processes such as coal burning presents a huge issue for climate change. It is also an impurity in energy sources such as natural gas.

Workers at University of California, San Diego, University of South Florida and King Adbullah University of Science and Technology have discovered that hexafluorosilicate may be used as a very efficient way of capturing CO2.

A recent article in Nature describes their finding. One of the most exciting aspects of using this material for CO2 capture is that it works well in the presence of water vapor, which others materials used for this function have not been able to do. [http://www.nature.com/nature/journal/v495/n7439/full/nature11893.html - Nugent et al., Nature 495: 80-84 , March 7, 2013, doi: 10.1038/nature11893]

USF Graduate Student Stephen Burd under the direction of Professor Michael Zaworotko did initial testing of the material, which led to the formation of the international group.

Environmental Imagery in The Great Gatsby


I gave a lecture a few months ago that brought together some elements of literature and art in the development of the environmental movement.  I am always drawn to bring out The Great Gatsby when I speak of the history of the environmental movement in the United States.  In many ways, The Great Gatsby did to romanticism in American literature what Daisy Buchanan did to Myrtle Wilson in the book.  Thus, Gatsby, to me, serves as a distinct cultural line between Muir and Leopold.

But Gatsby delivers some interesting environmental images that are key to my viewpoint.  There are two symbolic environmental images.  One of course is the ash heap between Long Island and New York City.  This area was portrayed quite nicely in Baz Luhrmann’s new film adaptation of the classic American book.

The ash heap was a real place, now Citi Field where the Mets play in Queens.  It was a dumping ground for the coal ash and other waste from New York City.  Any of us who drive from Long Island into New York have driven by the area, just as Gatsby would have back in the 1920’s.  Now, of course, we take the expressway instead of the roadway.  Robert Moses removed the landfill to create space for the 1964 World’s Fair and the ash heaps are no more.

But the presence of the ash heap in the 1920’s book symbolizes the cost of excesses of the times.  The fact that that Tom Buchanan, representing the old moneyed elite, finds disposable love with a decadent earthy woman within the shadows of the heap foreshadows the loss of beauty within our own natural world as a result of overdevelopment.  The death of Myrtle is the death of nature.

But thankfully, we have resurrected the smoking ash heaps of the past through the reconstruction of wetlands and construction of parks.  We have reshaped nature so that it is a genderless construction of modernity that would be lost to past symbolic realism.

The other important natural image of the book is the blinking green light on Daisy’s dock across from Gatsby’s mansion.  To some, the green light represents Gatsby’s dream of the past with Daisy.  But to me, it has always meant Gatsby’s dream of a simpler world—a world without the burden of excess, a world without decadence, a world of truth that he could share with Daisy.   While he wants Daisy in that world, it is quite evident by the end of the book that while he has hope of the future, Daisy is unworthy of his dream.

Thus the green light represents the hope that all of us have in the value of others and our dreams for the future.  The green light is elusive—seen, but not held.  Visible, but not understood.  Thus the green light takes the place of nature in providing a sense of the unknown—it is technological nature romanticism.  Instead of being inspired by nature to gain the romantic, Gatsby is inspired by electricity.  For the first time in American literature, a romantic symbol, one typically found in nature, becomes technologic—a blinking electric light.  Nature is not needed to elevate the soul.

I live in the land of Gatsby.  After work, when I go out for a run from my modest neighborhood adjacent to one that is not, I find myself pulled to the moonshadows of Gatsby’s mansions because of the broad running space and lack of traffic.  I suppose I race against time among the ghosts with my little LED headlamp.  When I get home, tired but fulfilled, I try to find the green light across Manhasset Bay.  Some evenings it is there.  Some evenings it is not.

Karst and Tourism in China

I was poking around Youtube and ran across this interesting travelogue about Yangshuo, China, a major karst region.  The region is a major tourist destination and the site of lots of beautiful landscape.

I'm in the midst of grading and it was a nice distraction from reading papers and exams.
