A Little Forestry

By | November 8, 2021

This evening we had our very own Apex Lion Paul Dean for our speaker! Paul, who is a semi-retired consulting forester, provided a presentation on the role our global forest plays in the carbon dioxide cycle.

With all the discussion about global warming and climate change, Paul provided a simplified description of how the high concentration of atmospheric carbon dioxide can be measured by ice cores containing air bubbles dating back 900,000 years.

Paul showed that annual fluctuations of carbon dioxide are tied to earth’s summer and winter solstice events and the fact that the bulk of humans and forest are in the northern hemisphere.
