Another problem with the public perception of Climate change is that everyone links climate change directly to "Everything's going to be warmer all the time", which isn't the case. For example, I experienced my new personal record for cold temperatures this past winter: -42 C, with a wind chill around -50 C (that's -40 F, with the wind chill around -58 F down into the -60s, for those paying attention in fahrenheit). This was likely caused by the changing climate up north.
Climate change means the everything about the climate is changing. Plains could turn to desert, rain forests into swamps. The sea level is going to rise with the melt of the ice caps. I don't mean to be the one crying "The SKY is FALLING", but we've got to look at coping strategies now. It's too late to try and reverse it, all we can do is work our ass off to try to keep it from getting worse than it is.
