CO2 Misconceptions: Debunking Doug LaMalfa on Climate Change

What percent of our atmosphere is CO2? In today's video, we debunk Doug LaMalfa's argument that because CO2 accounts for a seemingly tiny 0.04% of the atmosphere, there is no reason to worry about manmade carbon emissions, other greenhouse gases or global warming induced climate change. Watch on to find out more!
