Obama’s Idea of Clean Energy: Nuclear Power?!

February 25th, 2010

In a recent speech given at a jobs training center for energy hardware and software in Lanham, Maryland, President Obama announced controversial decision to break ground on the first nuclear power plant in 30 years.  Obama addresses both sides of the environmental and economic debate surrounding clean energy.  A major point he makes is that  nuclear power is cleaner for the air: it will prevent 16 million tons of carbon dioxide emission each year, the amount that a coal plant of similar scale would produce.  This is the equivalent of taking 3.5 million cars of the road.  Using more dubious logic, Obama states that our “competitors”, referring to other nations such a France and China, are building nuclear plants, and creating jobs for their citizens, and we need to keep up with them to keep the economy strong.

What’s your opinion of Obama’s energy strategies?

Kyoto Protocol: An Anti-Climate-Tic Ending

October 19th, 2009

titlephotoAs 2012 draws closer and closer, so too does the end of the prestigious Kyoto protocol.

The Kyoto protocol is a global initiative aimed at stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system.  Which as most would agree is a great thing.

Although according to NPR, drafting a new agreement in the near future seems unlikely.  The reason for this is strong opposition from the United States Congress.  Although President Clinton signed the original pact, the U.S. refused to ratify the original agreement and is slowing the creation of a new draft because the original pact did not require any action from developing countries like China, which is the world’s largest greenhouse gas emitter.

Both the Bush and the Obama administration felt that this was a fatal flaw in the protocol. There has been little progress but not for lack of effort.  In an interview between NPR and European Commission Vice President, Margot Wallstrom, she said that it has been very difficult negotiating a treaty that the U.S would agree to and that all parties involved would rather be on track to a solution.

Hopefully these issues will be worked through in December when world leaders meet in Copenhagen to discuss next steps.

The Death of the Traditional Burial System

September 21st, 2009

The only guarantees in life are death and taxes. Of the two, only one has direct ecological consequences: death. Over 150,000 people die eSextonBeetle_wideach day, and there is only so much available space the world has to offer in which to bury them. So what’s the most environmentally friend thing to do with a dead body? Or as the great Shakespeare would say: to casket or not to casket?

There are several options: burying, cremation, freezing, “beetleization” etc., the list goes on. Most of you, I assume, have heard of the first three options, but unless you studied ecology at the University of Vermont, or google Bernd Heinrich obsessively, you are probably asking what beetleization is.

There is a breed of beetle called the sexton, or burying beetle. It’s a little critter, about the size of a bumble bee, and it can (and will, with the help of a mate) take that much bigger and very dead shrew and get it very quickly underground.

Heinrich explains how these beetles (they work in mom and pop teams) manage to find, lug and inter corpses many times their weight and size. Burial beetles are, says Professor Heinrich (who for years taught at the University of Vermont), “the undertakers of the small animals in the forest.”

So, with a few more beetles, it is possible to save some money on a mortician and a casket, and let nature run its course.

How to Save a City

September 21st, 2009

venice1$6 billion can go a long ways. It can pay for 25,000 students to attend Harvard, finance one month of the war in Iraq, and even re-build the World Trade Center with plenty left over to spare. But it might not be enough to save one of the most renowned cities in the world from despair.

It is no mystery that the 1,300-year-old island city of Venice is slowly sinking while the sea level is rising.  It’s known as “aqua alta” — high water — and it brings city life to a standstill for several hours. Big boats can’t go under low-hanging bridges, and water seeps into buildings through the sewage system. Venetians have not lived on the ground floor for decades.

So what can be done to remedy this fateful situation? Venetians are resorting to sophisticated technology to fight this full-scale emergency. The project is called MOSE, for short, which is also the Italian acronym for Moses, recalling the biblical parting of the sea.

Once completed in 2014, there will be 78 large, mobile flood gates at the three inlets. When not in use, they will sit on the lagoon bed. When a high tide is forecast, the gates will rise and shut off the sea from the lagoon.

But there is no time to waste, as the IPCC — the Intergovernmental Panel on Climate Change — has forecast a sea level rise by the end of this century of between 18 and 59 centimeters.

Farmer Invents Solar-Powered Lawn Mower

September 18th, 2009

091309r2aPeople are amazing these days. Last December, a 70-year old Indian woman gave birth to her first child. And now, just this past week, although not as physically impressive, a 70-year man from Colorado invented a line of solar-powered lawn equipment. So much for moving to that lakefront property in northern Florida.

Tom Lopez, the man behind the invention, lives on 120-acre Lone Hawk Farm just west of Hygiene, CO. With that much land to cover, it makes perfect sense to create a solar-powered lawn mower. And the best part? It wasn’t even that difficult to make.

“That’s the thing about this stuff — it’s not rocket science,” said Lopez, a 1962 University of Colorado-Boulder graduate with a degree in aerospace engineering. “It just uses standard technology.”

Lopez has built several mowers and tractors by himself, and is working with another company on mass-production. That’s good timing, because after being featured in a national magazine, Lopez is getting calls from all over the country.

“One local (customer), and the rest are nationwide,” Lopez said. “I’ve even got one in Alaska.

One Colorado farmer’s invention could go a long way to decreasing pollution all over the world.

Farming in the Sahara Desert

August 4th, 2009

090731-green-sahara_bigPicture the Sahara Desert as a farming community. It just doesn’t seem right. Scientists have found emerging evidence that suggests the desert is greening due to increasing rainfall, and if sustained, the precipitation could revitalize drought-ravaged regions, reclaiming them for farming communities.

While global warming is causing panic in the United States, the rising temperatures could benefit millions of Africans in one of the driest places in the world.

This desert-shrinking trend is supported by climate models, which predict a return to conditions that turned the Sahara into a lush savanna some 12,000 years ago.

Images taken between 1982 and 2002 revealed extensive regreening throughout the Sahel, according to a new study in the journal Biogeosciences.

The study suggests huge increases in vegetation in areas including central Chad and western Sudan.

“The transition may be occurring because hotter air has more capacity to hold moisture, which in turn creates more rain,” said Martin Claussen of the Max Planck Institute for Meteorology in Hamburg, Germany.

Dubai Gives Liftoff to New Ecosystem

July 31st, 2009

farm00Only Dubai, a city that has practically sprung up overnight with some of the world’s most jaw-droppingly creative architecture, would construct an ecosystem reaching into the clouds.

Since the Metropolis has a severe lack of natural resources, the country hired Italian architects from Studiomobile to conceive a Seawater Vertical Farm that draws exclusively upon natural resources to create a sustainable source of food, for a cleaner, greener, and more self-efficient Dubai.

Envisioned as a spire that branches off into soaring sky-gardens, the design uses seawater to create an ecosystem conducive to growing crops amid the clouds.

Powered exclusively by saltwater, the new structure would allow Dubai to significantly cut down on food imports, reducing the region’s oil dependency and greenhouse gas emissions by decrease their reliance on transportation.

Based upon the design of Seawater Greenhouses in Oman and the Gran Canarias, Studiomobile’s ‘Seawater Vertical Farm’ utilizes seawater to cool and humidify the air that ventilates multiple greenhouses, while sunlight distills the saltwater into fresh water to provide life for thousands of plants.

The New Environmental Solution

July 31st, 2009

biocharAdding crop residue, bones, and manure to our soil could cure all of our environmental woes. If you don’t believe me, ask Brian Bibens, a research engineer with the University of Georgia’s Biorefinery and Carbon Recycling Program.

This intriguing soil combination called “biochar” was first used hundreds of years ago by indigenous people of the Amazon River when they added a mixture of charred organic materials to their soil, creating vast and fertile farmland that is still some of the richest soil on Earth today.

“The idea is that by putting char in the soil you can increase the fertility of that soil,” Bibens said.

As evidenced by Terra Preta, biochar can stay in the soil for hundreds, maybe thousands, of years, sequestering carbon, increasing crop yields and possibly improving water quality.

According to the International Biochar Initiative, because it is so stable, adding biochar to soil increases retention of nutrients so that less fertilizer is needed and therefore less is released as pollution.

How Global Warming Allowed for America’s Largest Empire

July 31st, 2009

MachuPicchu01People often argue that Global Warming isn’t real, but no one actually argues that Global Warming is a good thing. Until Now. An international team of researchers reported in the current issue of the journal, Climate to the Past, that a 400-year warm spell helped the ancient Inca to build the largest empire to ever exist in the Americas.

Beginning in about 1100 A.D., the increase in temperature served as a “perfect incubator” for the Inca’s expansion, allowing them to develop better methods of agriculture, creating a surplus of maize and potatoes, which freed much of the population to build a large army, road networks, and even Machu Picchu.

“Climate warming does not always have to be a negative issue. Our research shows that it can favor societal development,” lead author Alex Chepstow-Lusty, a palaeoecologist from the French Institute for Andean Studies in Lima, Peru, told Discovery News.

Peru, considered the third most threatened country in the world by climate change, needs to restore the vast areas of abandoned terraces and canal systems, build reservoirs, and focus its attention on massive scale native reforestation of the Andes, according to Chepstow-Lusty.

Smog: Putting the “S” in Stupid

July 22nd, 2009

smog2No wonder there are so many stupid people in the world. Researchers recently found that air pollution exposure before birth lowers IQ scores in childhood, providing substantial evidence that smog may harm brain development.

So next time you see someone turn the wrong way onto a one way street or try to iron a shirt they are currently wearing, don’t give them a hard time. Just think that maybe they grew up a block too close to the nuclear power plant or the oil refinery.

The results are in a study of 249 children of New York City women who wore backpack air monitors for 48 hours during the last few months of pregnancy. They lived in mostly low-income neighborhoods in northern Manhattan and the South Bronx. They had varying levels of exposure to typical kinds of urban air pollution, mostly from car, bus and truck exhaust.

At age 5, before starting school, the children were given IQ tests. Those exposed to the most pollution before birth scored on average four to five points lower than children with less exposure.

That may not seem like a very big difference, but it’s big enough that it could affect children’s performance in school, said Frederica Perera, the study’s lead author and director of the Columbia Center for Children’s Environmental Health.
