if you say you dont believe in global warming you're pretty much an idiot. i believe in global warming, because it happens. i also believe in global cooling, because it happens. the point in question is whether humans are causing it. the warming trend that lasted up until 1998 began in about 1850, long before industry started pumping out gases. also, there have been numerous periods before than that were both warmer and sustained for longer periods of time. eg. 2000 years ago, and 900 to 1350AD. combine that with the fact that the earth hasnt warmed for 11 years, with no statistically significant warming for 16 years and the warmists' argument sort of falls apart. should we be protecting the environment and being more cautious with our resources? yes, certainly. should we be worrying about a gas that makes up 1.3% of the atmosphere and which the oceans release 95% of completely naturally? no.
debate welcome. i study this at a postgrad level.
