In a surprising turnaround, the amount of carbon dioxide being released into the atmosphere in the U.S. has fallen dramatically to its lowest level in 20 years, and government officials say the biggest reason is that cheap and plentiful natural gas has led many power plant operators to switch from dirtier-burning coal.
The International Energy Agency said the U.S. has cut carbon dioxide emissions more than any other country over the last six years. Total U.S. carbon emissions from energy consumption peaked at about 6 billion metric tons in 2007. Projections for this year are around 5.2 billion, and the 1990 figure was about 5 billion.

In spite of clichè s about Nascar dads and Walmart moms, the actual share of voters nationally who are up for grabs is probably between just 3 percent and 5 percent in this election, polling experts say. The Obama and Romney campaigns are expected to spend on the order of $2 billion, in part to try to sway this tiny share of the electorate.
If the number of undecided voters is
less greater than the margin between the candidates do you get an uglier campaign?

College graduates earned less coming out of the recession, according to a May study by the John J. Heldrich Center for Workforce Development at Rutgers. Those graduating during 2009 to 2011 earned a median salary in their starting job $3,000 less than the $30,000 seen in 2007.
$27,000 is just slightly higher than the per capita income in the US in 2010.
An interview with Elon Musk includes this bit about why he got into the space business.
The thing that got me started with SpaceX was the feeling of dismay — I just did not want Apollo to be our high-water mark. We do not want a future where we tell our children that this was the best we ever did. Growing up, I kept expecting we're going to have a base on the moon, and we're going to have trips to Mars. Instead, we went backwards, and that's a great tragedy.
And speaking of Mars, JPL's Curiosity rover will be landing on the planet Sunday night!
Interfluidity on: Trade-offs between inequality, productivity, and employment
I think there is a tradeoff between inequality and full employment that becomes exacerbated as technological productivity improves. This is driven by the fact that the marginal benefit humans gain from current consumption declines much more rapidly than the benefit we get from retaining claims against an uncertain future.
Wealth is about insurance much more than it is about consumption. As consumers, our requirements are limited. But the curve balls the universe might throw at us are infinite.
