MIT Class Calculates the Carbon Footprint of "The Man"

The Man is not only keeping us down, he's got an annual 8.5 ton carbon footprint, more than double that of the average global citizen, according to a new paper released by an MIT professor and his class.

The Man, of course, is not actually a real person, rather it's the way that countercultural Americans have referred to "the system," particularly the established infrastructure of the country like the military-industrial complex, the civil government, and sundry other institutions that were viewed with disdain.

The MIT class, in a paper (pdf) to be presented at the IEEE International Symposium on Electronics and the Environment, estimated that no American, even the homeless and itinerant Buddhist monks, could get their total "share" of energy usage below 130 gigajoules, which is more than twice the global average, and directly correlated with carbon footprint.

That's because the basic infrastructure of the United States including police, roads, libraries, courts, and the military were allocated equally to all citizens of the country. Thus, even if one's personal consumption in terms of purchased products and lifestyle were minimal, he or she would still bear their share of the systemic carbon load, according to the methodology of this study. In common terms, each and every US resident is carbon-heavier other countries' citizens.

This is at least not unexpectedly bad news. Most in the green movement already knew Americans weren't going to shop their way to a better environment. Changes had to come to the system, and be designed in at all levels.

"There's a certain amount you can do as an individual," said Timothy Gutowski, the MIT professor of mechanical engineering who lead authored the paper, "but if you recognize this is a system-wide problem, you need system-wide attention to the problem."

That's going to mean cleaner power, say, solar concentrating power plants plus wind. Better transportation options need to speed to market, probably smaller electric vehicles and smarter mass transit options.
Materials like cement and plastics need to be made with far less energy. Cities will have to be redesigned to reduce the need for commuting. More efficient ways of transmitting, storing, and using energy at the grid and home levels need to be mainstreamed. What we eat will have to change; the challenge will be making the future food taste as good as the corn-based delicacies that populate our menus now.

It's a big challenge, but Gutowski and his students have shed light on a major issue: if we want to lighten our impact on the environment, we have no choice but to get The Man to take action on the problems He's creating.

Is it time to talk about 'peak water'?


Water is the new oil--a resource where demand continues to rise but supply is limited.  Experts at the Ceres Conference here on Tuesday focused on the risks to businesses and communities that the "global water crisis" poses, one with economic, environmental, and human health impacts.   Desalination might be a solution.  This is the water planet, after all.  However, desalination takes energy.  Where is this energy going to come from?

Emptying the Breadbasket in the United States

For decades, wheat was king on the Great Plains and prices were low. Those days are now over. Farmers are abandoning wheat for soybeans or crops intended for biofuels. They go for the best return on investment. A farmer can't feed his family with tradition. Congress has distorted the market with subsidies for biofuels including ethanol. We can't afford to let politics determine which crop is going to return the most money. People are beginning to go hungry.

Nature's carbon balance confirmed

Scientists find evidence that a natural feedback mechanism regulated CO2 for hundreds of thousands of years.  Now we are taking all of the carbon out of the Earth and pumping it into the air so fast that the Earth is unable to remove it.  We are already beginning to see the consequences.  Hopefully, because of the new awareness of the problem, we will come up with solutions before the consequences get worse.

Can renewable energy make a dent in fossil fuels?

Energy consumption will continue to go up for the foreseeable future. This article looks at where we are going to get this energy from. It is going to take a lot to wean us off of fossil fuels.

4.2 billion. - That's how many rooftops you'd have to cover with solar panels to displace a cubic mile of oil (CMO), a measure of energy consumption, according to Ripudaman Malhotra, who oversees research on fossil fuels at SRI International. The electricity captured in those hypothetical solar panels ...

Carbon Dioxide, Methane Rise Sharply in 2007

Last year alone global levels of atmospheric carbon dioxide, the primary driver of global climate change, increased by 0.6 percent, or 19 billion tons. Additionally methane rose by 27 million tons after nearly a decade with little or no increase.

There has been lots of talk about what we need to do to bring the emissions of carbon dioxide down, but we are not seeing any results yet.  The methane increase is really scary if this indeed is a portent of future increases in emissions as the result of warming in the Arctic.

Mapping the U.S. carbon footprint

Researchers have mapped the country's carbon footprint. The data is mostly from 2002. Next they plan to pinpoint CO2 down to each rooftop.

This site not only talks about the research but also presents the results of the research in the form of a YouTube video. The animated graphics in the video give the impression of a pump which is disgorging CO2 daily into the atmosphere.

In the video it is very easy to pick out Carbon County, Wyoming, in one of the maps which shows the release of CO2 into the atmosphere. This is the county where much of the nation's coal is being mined.

Global temperatures 'to decrease'

Global temperatures this year will be lower than in 2007 due to the effects of La Nina, UN meteorologists say.  I wonder if anyone has looked into the effects of all the melting ice in Antarctica.  Isn't it possible that all of that cold ice and cold water would cause La NiƱa?

If that is the case, then the question becomes, would the cooling caused by this process be enough to counterbalance the warming effects of the extra CO
2 humans are pumping into the atmosphere.
