Arctic Sea Ice on the verge of collapse??

Arctic Sea Ice

Every September, Arctic sea ice reaches it's yearly minimum. While some experts have estimated that we might see an ice free Arctic this year or the next, most scientists probably agree that 2020 is more the consensus view. However, the image below shows a recent drop in sea ice extent that is so dramatic (red line) that some think it could be something wrong with the measurement (it was a measurement problem!). 

But still it's a very strong reinforcing feedback in the climate system that will increase further warming. IPCC's models were so very wrong regarding the Arctic, they predicted this wouldn't happen until the end of the century. Now we know that too conservative climate science can be dangerous too.
