The South Central Climate Science Center has a series of short videos which cover a variety of aspects of climate science and climate change information. Most of the videos are around 5-7 minutes long and provide information on topics like the carbon cycle, how we measure past climates, and how climate models work, but they also include chapters on the IPCC, environmental economics, and impacts to crops and livestock.
