We're causing extremely rapid global warming - the Arctic ice is clearly going to be gone in summer in the next few years, and that's a substantial positive feedback which will accelerate other, larger positive feedbacks such as permafrost decomposition and release of methane from seabed hydrates. There is little prospect of this changing any time soon, because greenhouse gas emissions are rising faster than ever, and it will take decades to turn that around, even when it becomes painfully clear to everyone that we have to.






















I fear you're right about positive feedbacks leading to almost inevitable catastrophe. It's time for planning bold interventions. I fear major famines in poor countries are just a year or two away.

how do explain the growth of glaciers?and colder temps?

Global temps have been increasing. Most of the hottest years on record have been in the past decade.
Antarctica is still a very cold place, but the waters around it have been gradually warming. Thus the major retreat of ice shelves. Glacier outflow of the West Antarctic Ice Sheet (WAIS) has increased dramatically. That whole ice sheet can become unstable, and the ice there would raise global ocean levels by many feet.
Your link compares two cherry-picked dates in DECEMBER!!!
Sea ice changes rapidly in early winter....any two years can look completely different on the same December date, and it means nothing.
Accurate comparison requires looking at ice at the annual minimum, always early to mid September. That's what I've shown above. Look for yourself:
