Dedicated to the balanced discussion of global warming
24 Hour News & Blogs – September 9, 2007
This is a very interesting post on this news site that compiles and discusses the observed phenomenon that historically CO2 rises after temperature rises. Real Climate goes on to describe that this rise in temperature is aggravated by the warmth absorbing properties of the increase carbon dioxide.
One would assume that this is a runaway train. Temperature rises then CO2 increases causing more temperature increase which should cause more CO2 to enter the atmosphere. But something has happened in history that we don’t seem to understand – eventually, the temperature drops and so does the CO2.
Does Earth have a temperature (and CO2) regulator? The answer is probably in the oceans since this is the one big thing that other planets in our solar system do not have. But I can’t seem to find any conclusive theories as to what is really happening.
It seems to me as if there hasn’t really been much attention given to the fact that CO2 increases occur AFTER the temperature begins rising and therefore cannot be the initial cause of global warming. Even the most vocal proponents of anthropogenic global warming (AGW) acknowledge this fact.
The interesting thing to me though is what causes the warming to stop, even though CO2 is still RISING?
But once it reaches that threshold, what makes the temperature start to fall again, especially if CO2 levels are still rising? Does the earth have a built in temperature regulator? Does melting of the Arctic ice slow down the thermohaline circulation enough to initiate a new ice age?
