Arctic Melt Increases

Previous predictions need yet new update.
The article is thought provoking and confirms the general assumption that feedback processes have not yet been included in many models.
In this case, disappearing ice sheet would reduce reflection that would send heat back to space and in turn increase the amount of trapped heat. Would be interesting to see if this was factored in the assumptions.
Also, the IPCC May Report that was issued for policy makers around the world has admittedly not included the fact and consequences of faster meltdown.
The report also seems to confirm expert predictions often cited on this Change Climate Back blog that 30-40 year changes have already been locked in and are largely due to the amount of carbon dioxide already trapped.
