This loss is exacerbated by the intensifying Climate Destabilization (reportedly reflecting the start of the «Albedo Loss» feedback due to the decline of Arctic sea - ice and ice caps) which is suppressing subsistence farm yields and some commercial farm yields on a random basis by the impacts of extreme droughts, storms, floods, and heat and cold waves.
The fact that I can point to the majority of models not predicting this fast of a decline, and you can point out a few that say that it might have started by now and it hasn't, totally ignores the fact that either way, sea ice is diminishing and that is consistent with accumulating heat in the Earth's climate system.
I could go down warrenlb's list, starting with his false assertion that Arctic sea ice is «in rapid decline» [it isn't], as I have done several times before, but why bother?

That winter was also to be the coldest in the UK since 1978/79, when climate scientists were still scaring us with stories about imminent global cooling and satellites were only just starting to measure the temperature of the lower troposphere and the beginnings of the «catastrophic» decline in Arctic sea - ice.
