   Arctic sea ice experts say they never claimed that ice-free meant that there would be *no* ice in the Arctic. Climate change defines ‘ice-free’ as when sea ice thickness falls below 1.5 meters. This threshold is already a dramatic increase of almost 1.5 meters since the 1970’s, when human emissions overwhelmed natural climate forcings. Climate scientists are dead-certain that this dramatic shift is man-made.

   As the globe continues to warm, the ice-free ice thickness threshold is predicted to increase by up to an additional meter by 2100. It is worse than we thought.

     “Human emissions overwhelmed natural climate forces” only inside computers, but not in the empirical world of observations in which competent scientists collect and analyze data. The historical warm periods that occurred in the last few thousand years with far lower CO2, and the fact that CO2 increases seem to follow warming both indicate that this comment grossly is incorrect. Of course, there are many more falsifications to AGW.

   It is their game and therefore they are allowed to move the goal posts anytime it is needed to “prove” their point!!
