In the supplied temperature vs carbon dioxide chart it’s important to note that carbon dioxide changes FOLLOW temperature changes by 800 years. Carbon dioxide changes CAN’T cause the observed temperature changes.
What’s the cause of the observed changes in both temperature and atmospheric carbon dioxide? The distance between the sun and the southern oceans in southern summers. Changes in solar radiation striking earth’s southern oceans cause greater and lesser ocean absorption rates of atmospheric carbon. As the writer points out, the process is governed by earth’s 105,000 year orbital precession cycle included in the Milankovitch cycle.
“carbon dioxide changes FOLLOW temperature changes by 800 years.”
Thanks for posting, as that is very important. Effects follow causes. The temporal succession suggests that warmer temperatures cause an increase in airborne CO2. Boyle’s law? It’s my understanding that the oceans breathe. Cold waters from the poles travel to the warm equator and exhale CO2. As those waters travel back towards the poles, they cool and inhale CO2. If the planer were to warm, the oceans would release CO2 into the atmosphere.
