Reply to "Recommendations for Television Shows"

PBS's NOVA "Polar Extremes" 2/5/20 release. 

I wouldn't normally recommend a single episode in this thread, but this 2 hr show kept me thoroughly engaged as it went through geologic time with the earth's climate and its drivers.  Made very good comparisons to times when CO2 levels were higher. We are currently over 400 ppm, well above the 180-300 ppm range that has existed for thousands of years during this time of inactive volcanic activity. You'll come away with a much better understanding of climate change.
