Host Hank Green runs through five specific consequences of climate change in this short SciShow Infusion episode: rising sea levels, melting polar ice caps, stronger hurricanes, water scarcity, and food insecurity. He explains the mechanism behind each one, from how warmer oceans add energy to storm systems to how shrinking glaciers and ice sheets translate directly into coastal flooding. The format is Hank talking straight to camera with graphics and data points layered in, no field footage or interviews, in keeping with the rest of the Infusion series alongside entries on solar energy and epigenetics. The tone stays close to a straightforward science briefing rather than an advocacy piece, laying out what current research says is likely rather than arguing for particular policies. It runs through the five threats one at a time and stops there.
