Very Good contribution to an understanding of the carbon cycle, an important aspect of climate science. One suggestion: by percentage, ocean phytoplankton are the largest carbon sink in Earth's carbon cycle. The deep ocean holds a few orders of magnitude more dissolved carbon than the entire atmosphere. If you decide to re-edit this video, including a brief discussion of the part our oceans play in carbon sequestration would be useful. Full disclosure: I am working on a way to help ocean phytoplankton have access to more natural nutrients so they can live longer in a season and sequester more carbon naturally. On balance a very good educational video. Thank you for creating it.
The statement in this video that the increased carbon dioxide levels of the past caused warming (with accompanying flames in case we missed the point) is also incorrect. CO2 levels were always (except for the dip mentioned here) around 2,000 - 4,000ppm (5-10 times the present level) and global temperatures notably did not reflect this. The belief given in this video is a recent invention.
Please note, the record shows NO significant correlation between CO2 levels and global temperature over the period described. Global CO2 levels have nearly always been much higher than today, but gradually declined during the last 160 million years mainly due to the expansion of animals with carboniferous shells. It is now at a record low. The release by human activity of the carbon that got 'stuck' 300 million years ago is now being recycled, which is causing a readjustment of the carbon cycle. Had it continued declining to would become too low to support photosynthesis in about 6 million years, and so all vegetable and animal life on Earth would go extinct, probabaly permanently.
CONGRATS this is EXCELLENT !!! ... (only 400 views in 9 months makes no sense at all)
BAG was here - such a solid vid Jac, thrusting geology into the future :)
This was very helpful for my class of 7 siamang apes, good job!
Wow! Great visuals to help understand geologic concepts.

Shellfish are selfish. They would sink all carbon to the bottom of the sea.
The assumption that CO2 heats the earth is incorrect.
