On the 6th September, meteorologists released a report examining statistically significant weather phenomena and guaged whether anthropogenic global warming could be identified as a causal factor. One of those events was the Arctic ice area in 2012, much reduced, and explained as a response to global warming. This also remains the controversial response of the IPCC.
As for “the extremely low Arctic sea ice extent in summer 2012,” the report says this resulted primarily from the melting of younger, thin ice from a warmed atmosphere and ocean.
“This event cannot be explained by natural variability alone. Summer Arctic sea ice extent will continue to decrease in the future, and is expected to be largely absent by mid-century.”
Arctice ice cover was set to decrease. And now? It has increased by 60% this year after record lows. There is also the significant matter of the 'global pause'. For some reason, we are not given a reason for the increase, except for the vague notion of variability. This programmed bias raises scepticism; its simplistic, circular arguments in the media
