These articles really do damage to the chicken or the egg co2 arguement in past warming from ice cores.
Did co2 cause the warming or did warming cause the co2.
Dispute my hypothesis.
That methane thats under the ice was probably the remains of plant/organic material that was left behind when there were actual plants growing in those spots.
How much methane was released when the last iceage ended and a size of ice several times larger melted then we have today. The ice we have at the poles today is a fraction of the original sheet.
