Lobiusmoop said "directly or indirectly". Cattle in feedlots eat corn grown with fertilizers made from previously sequestered oil. If you use oil or coal that took millions of years to sequester then you're not neutral. Whale's don't add any previously sequestered carbon to the biosphere (unless they drink straight from the BP wellhead).
How many people use a rail line from one terminus to the other? I've taken Amtrak hundreds of times, but the absolute longest journey was D.C. to New Haven in a snowstorm when the airports were closed. The rest were Boston to New Haven, New Haven to Philly, etc. This project puts China at the center of a network and makes other points on the network both more important and more dependent on China.
IANAAS (atmospheric scientist) - I waste way too much time puzzling over this stuff. It's probably covered in atmostpheric science 101. I answered because I remembered different numbers than yours; I had to go search for that site. I agree about the bad name thing - too much simplification without enough surrounding explanations.
Know any good (non-political) books?
Careful - there is disagreement on the numbers. Methane contributes to the production of ozone in the tropsphere. Methane (with a half-life of 8.4 years) is 1/4096th of its original concentration after 100 years. The relatively high GWP after 100 years includes the secondary effects and we don't yet know how those will grow (or shrink). Check out http://unfccc.int/ghg_data/items/3825.php
From what I've read no computer can model DNA behavior faster than DNA itself can manipulate a supply of proteins. The kill switch might be there so that they can "run" massively parallel variations and use the kill switch as a sort of debug breakpoint. But IANAMB (molecular biologist).
Look, it might not be in the constitution, but there was this little dust-up called the Civil War that decided the line between states and Federal jurisdiction. If the states can override federal marijuana laws they can also override slaverly laws. So lets not throw away federalization, lets fix it.
BTW - Who says a write-in needs to be 70 days before? Isn't the whole point of a write-in something done ON election day?
