That sounds very conspiracy-theorist. Spain has had a decent snowfall over a wider area than usual, however the whole country is not under snow down to all levels. The -34 C reported in the Pyrenees earlier this week was measured by a brand new station (1 year old) sitting in a blow 2305 metres up on the top of a mountain. It's certain that such a low temperature has occurred in that place before and was just not observed. In any case, one event does not a winter make.
But yes, the predictions of doom re. sea ice have been shifted and shifted out year after year to the point that such predictions are as frequent and questionable as the annual Daily Express headlines of "Worst Winter in 50 Years On The Way".
Meanwhile there are still huge areas of the planet that are completely unmonitored and their weather is calculated from the average of two or more weather stations 100s to 1000s of km away. Many of the places that are furtherest away from human activity are the least monitored, but have their weather calculated from places close to human activity.
