How do you explain the presence of carbon in permafrost? For the concentration of carbon in permafrost to exceed the present concentration of carbon in the atmosphere, wouldn't the concentration of carbon in the atmosphere at the time the permafrost was initialy frozen have had to exceed the current concentration of carbon in the atmosphere? Which would imply that the current level of carbon in the atmosphere is not the cause of the increased temperature?

Do you think permafrost is giant bubbles of air that got trapped in frost or something? Your comment baffles me somewhat. What do you think of the concentration of carbon in our current atmosphere when you see a rotting log?
