The story "Luminous" by Greg Egan, from the collection of the same title. What happens when mathematicians discover that: (a) there is a flaw in the structure of mathematical truth; and (b) that mathematical truth can be altered by performing calculations around the flaw.
Someone has already collected a bunch of mathematical fiction here.
tl;dr version - emissions will go down when it's cheaper to produce green energy than to burn coal, and not one moment before.
Two words: Carbon tax. Oh, did I say the dreaded "T" word? Please beat me senseless now, Mr. Norquist.
Downtown cores suck. It's called a concrete jungle for a reason.
Downtown cores suck because they're designed that way, by people who hate them because they've never experienced anything better. Older, highly dense city cores in Europe, on the other hand, don't suck -- because thought was put into their design. Read James Howard Kunstler to find out more.
"2012 will be a rich year for equity capitalizations, giving energy entrepreneurs the capital they need to build infrastructure." Sounds great, but it's wrong. The financial system is sick and corrupt and the capital he's talking about is largely an illusion. The major financial institutions (Citibank, JPMorgan, etc.) only present a facade of solvency because mark-to-market rules have been suspended, so they have been allowed to hold toxic assets on their books at the values their models predict (the models that were proved devastatingly wrong in the collapse of 2008) instead of what they could actually fetch in the market. If it were ever brought in contact with reality, the world financial system would die instantly. Instead it's basically being strung along by the U.S. federal government (i.e., taxpayers) in the hope that this was a one-time thing and at some point, something like solvency will return.
The fact is we are in a deflation right now, with debt-based capital disappearing from the system at a prodigious rate, while the U.S. Federal Reserve is using quantitative easing (i.e. manufacturing more debt on its own balance sheet) to hold the process back and try to restore growth. The financial system is sick just when we desperately need capital to start rebuilding our energy infrastructure. I would refer anyone to The Automatic Earth if they want to learn more about the energy and finance predicament that we're in.
Those of us who are a certain age and were geeky enough to read Danny Dunn books know exactly where the CIA got this idea.
(Luckily Danny was able to destroy Professor Bullfinch's notes so the CIA wouldn't be able to replicate the much better dragonfly he'd invented, so they had to fall back on tiny, impractical gasoline engines instead.)
Boo, you got there first! If I couldn't post first about DD, I wish I had some moderator points so I could upvote. Just hearing the name Danny Dunn makes me feel like I'm ten years old again, curled up at Riverside Library. Ah, memories...
