Carbon Dioxide rises from 800,000 years ago- Lecture from Antarctica

In addition to the lectures that JP and I did on our Antarctica trip, we also had some fantastic lectures and discussions with some of the scientists aboard. Bob Gilmore presented a non political discussion on climate change that was incredibly informative The video below puts it all in perspective. It shows the history of atmospheric carbon dioxide from 800,000 years before present until January, 201. The ups and down in each year are attributed to winter and summer. In the winter the trees lose their leaves and thus Carbon Dioxide rises and in the Summer when the trees have all their leaves Carbon Dioxide is reduced.

Our 2019 trip to Antarctica is sold out and we are now taking reservations for 2020.
