Why people attribute this crap to global warming I have NO idea. One major volcanic eruption spews more "pollutants" into the atmosphere in ONE eruption than the entire human race has put into the atmosphere since the beginning of the industrial age. So, being that we are fleas on the backs of a dog, and taking unneccessary credit for NORMAL TERRESTIAL WEATHER PROCESSES, where does that leave us? Global warming is not something we HELP, but it's definitely NOT something we've caused. Remember, we are in an interglacial period, the last ice age ended not even 12,000 years ago... (more like 10,400). Here's some science (GASP HEAVAN FORBID REAL SCIENCE AND NOT DOGMA) to help you to understand how it works:
