The issue seems to be so politicized that all sources seem incredibly biased. Sure, there might changes happening, but from history, isn&apos;t that what the climate does? It seems that one side portrays it as no big deal, and the other says we&apos;ll all die in a few decades.&lt;p&gt;I&apos;m not looking for something telling me how to behave or react, just something that covers how/what we know for certain. Or is the science and understanding required too far out of reach for laymen?</text><parent_chain></parent_chain></comment><story><title>Massive glacier collapse</title><url>http://unofficialnetworks.com/collapse-video-glacial-size-city-116670/</url></story>

I went with friends who study adaptation to climate change in the Arctic communities, and all of them, and I too, came out of the movie in a state of minor shock. It&apos;s truly incredible how much these intense visuals make this strike home, even for those who are already environmentally aware and focused. It&apos;s the kind of movie that solidifies the thoughts I&apos;ve been having recently: my life absolutely must be about working to mitigate and slow global climate change. Any other career path or choice would be so morally wrong I would have great difficultly living with that decision.&lt;p&gt;Everyone should see this movie.</text><parent_chain></parent_chain></comment><story><title>Massive glacier collapse</title><url>http://unofficialnetworks.com/collapse-video-glacial-size-city-116670/</url></story>
