Well well well. Look at the weasel word "imply". And of course it says nothing about ice at higher elevations elsewhere. You would think from the way they are talking that air doesn't circulate.We show that sea surface temperatures near the North Pole increased from approx18 °C to over 23 °C during this event. Such warm values imply the absence of ice and thus exclude the influence of ice-albedo feedbacks on this Arctic warming.
Don't sceptics do science any more? Or is scepticism the sole province of engineers these days?
