@Jamie: "I would love to be able to use this statistic in future, if it is anywhere near accurate. Where are you getting it from?" - i am quoting wikipedia, haven't looked at their sources, but i imagine that it is based on several different sources, (like the CIA factbook)
@rlumley: "Umm, no. Earth has cooled in temperature for the past 11 years. But nice try. And the Earth's temperature is much more highly correlated with sunspot activity on the sun than CO2 emissions."
but the earth's average temperature is largely based on ocean currents, and the expected cooling is much lower than expected. (so if you take the average over ~22 years it is still going up) When this cooling cycle (largely dependant on Pacific sea currents, if my understanding is correct) ends - around now - the average temp will increase.
Temperature on earth is also larely based on cloud cover (because clouds are white, and white things reflect more light into space than green/yellow earth or blue seas (as seen from space) though not more than white ice caps - however increased cloud cover will only result from an increase in evapouration (thus higher global temperatures, more rainfall, and in different places, causing both drought and flooding, depending on how lucky you are) - i don't really buy the sunspot theory - though the sun's energy output does vary on an 11 year cycle, if you blame global cooling on that you still have to worry about what happens in the hot part of the next cycle - how and ever, irrelivant of things which affect our climate, CO2 does insulate us, and increased levels will alter the average temperature. That is understood and accepted by all scientists (how big that effect will be is more difficult to tell - so don't go telling me some people don't accept this part of the theory - quote me specific blog entries/scientific literature if you have any - the burden of proof lies with you now that the IPCC has had it's word)
But no, I wasn't going to bring up climate change - I was talking about US energy independance. Do something smart with your money, and if China insists that they have the right to emit as much CO2 as the next industrial country per head of population (and they largely have agreement on that with the rest of the developing world) then they will be emmitting way more than they are at present to catch up with the US. Until you cap your emissions you will find it hard to get any agreement from the Chinese. (and your economy depends on their's so good luck in an economic war) That said, i know a few US states are actually doing something to about their own emissions (see: http://articles.latimes.com/2009/apr/24/local/me-green-fuel24 just as a little link i found - California to limit greenhouse gas emissions)
Anyway, a lot of my point must sound very anti-american, but that it only sounds that way because the points i am adressing are the things which I see America as doing wrong/badly. That doesn't mean i don't think America is generally a force for good in the world, and one of the best hopes for the future.
to re-iterate.
1) Education - your system lags behind a lot of other western nations, I believe you owe yourselfs better.
2) Health - As i pointed out in the abortion thread, if you believe society should protect life at all costs, then you are against abortion and I can't see how you are willing to let these lives live in pain, and die in misery. If you truely value life and believe society is right to step in and keep it around then how can you not also support universal health care - several European countries, and Canada have better infant mortality rates and better life expectancies - learn from the successes and also the failures of these nations. Again this is your choice, and it is my opinion that you can and should do better. (but spend your tax dollars where you want to)
3a)Foreign Policy - Policing the world - by going alone against he rest of the world you have chosen to shoulder a huge amount of the cost of 'policing the world' - admirable if you are successful, unfortunately by going it alone you also appear not as some international police man but as an Expansionist Imperial power, which as history should teach you has usually encouraged rebellion and opposition.
3b)Foreign Policy - Energy policy + Oil usage - the last time the US placed limits on car emission standards was during the 70s when the oil crisis hit (when Iran had a little Islamic revolution) Your government then proved it had the capability to enfore limits, and your industry proved able to design the technology to meet those limits. Japanese and EU emmission standards make for considerably more efficient cars. (and the policy is based on the fact that Germany and Japanese foreign policy can't guarentee ever increasing Oil usage, they can't afford it, and only through your foreign policy can you) I am cerainly of the opinion that you can o better here (for yourselves, but it would also save you much on militrary expences and allow you deploy your troops in the best places - not based on a policy of getting the most oil, but instead on a policy of successfully keeping peace around the world - something which could be a useful tool to improve popular opinion and decrease the likelyhood of another terrorist attack on American soil - oh and do it with European, Russian, and Chinese allies.
The fact the reducing your oil usage/dependancy suits the anti-global warming movement is secondrary to your own security. (if you actually believe the science behind the global-warming theory then preventing it is the most important thing you can do for your own securiy, but that's a completely seperate debate)
