Of course. I never once claimed we shouldn't improve our impact upon the planet. The healthier we are as people, the healthier the planet is. I just don't understand why people treat climate change like a problem to be solved.
Because what is usually referred to as "climate change", that is, due to increased level of greenhouse gases in the atmosphere, is anthropogenic, thus we actually have some level of control over its course and direction.
Wikipedia proves the first two are definitely not myths. The United States is not the world's worst polluter. Hasn't been for a while. The United States is also not the worst polluter per capita. Surprise! Last time I checked, that was Guyana. (the title of worst polluter per capita changes frequently, Qatar and Belize being a couple of other title holders, but the U.S. has not held this dubious title in recent history)
And while my claim #3 is an educated guess, recent events such as China's and India's nose-thumbing at the Kyoto Protocol, prove that they're not going to "change course" any time soon unless a figurative gun is held to their heads. Got any evidence to refute that? Nope. There isn't any.
It is really hard to argue with someone who fails reading comprehension. When have I claimed that the United States is the world's worst polluter, per capita or otherwise.
I'll play along. According to Wikipedia, Belize is the worst "polluter" per capita as of AD2000, though this includes land-use changes (eg deforestation), which has a margin of error of up to 150%. Sans deforestation, the top of the list includes small petrostates like Qatar, which isn't surprising. The United States ranked 7th out of 185 countries, and 14th even including land-use changes, which isn't a stellar performance by any measure, worst than any other large country except Australia and Canada. Overall, China releases more CO2 than the United States, but American per capita emissions is more than three times that of China, and more than 12 times that of India (and also twice that of the European Union, and 80% more than Japan).
So Wikipedia in fact proved that the first two myths are, well, myths.
The only countries which could be argued to have nose-thumbed the Kyoto Protocol are Australia, Canada, and the United States. Both China and India treats climate change as national security issues; unsurprising since both countries will lose the most from a warmer climate.
