Global warming causes climate change. In other words, many people look around and are like "its been colder here than usual, global warming isn't occuring", but that is not true at all. Global warming causes climate change- so weird, abnormal weather- not necessarily hotter weather. The climate change we are experiencing IS the result of mankinds actions. The earth is going through a warming trend right now, but we are making it much worse- and it won't eventually end like all trends do, unless we fix our fuckups. Take a look around you and see all the shit we are pumping into our environment. If you don't think it is messing things up, you really need your head examined.

Harris7 will have lots to add on this topic I am sure, so let's see what he has to say.
