It seems that more and more people are talking climate change these days, but why is it important? How will global warming really affect us? Moving the global warming conversation from the esoteric to one that requires everyone's immediate attention, Link TV's new series Climate Change Hits Home brings you weekly stories of climate change's direct effects on us. As we inch closer to the UN Climate Change Conference in Copenhagen this December, check out the facts, videos and action ideas for improving the adverse impact of climate change on our planet.

You might have noticed the cool new "Beat Gasoline" banner on our homepage. So what's that all about?

It's becoming clear that relying on fossil fuels - oil, coal, gas - to power our increasingly industrialized world is no longer sustainable. Looking to promote alternative solutions to our sedentary car and gas-oriented society, Beat Gasoline is a cool new project from our partners at YouthNoise, a great engagement and activation organization working to create lasting change around the world by boosting the capacities of young leaders.

Beat Gasoline is looking for your videos and pictures showing how you are leaving the comfort of your couch behind to make a difference in the fight against climate change. So get out there and start filming!
