this is from "Arctic Sea Ice News & Analysis

the thick dark line in the middle of the grey band is the average ice cover variation per year for the period 1981-2010, and the grey is +/- 2 standard deviations

now have a look at this, which is the curves for the period 2002-2015 compared with the 4 standard deviations for the period 1981-2010 : all of them fall below the average line near the summer minimum ice cover

is there any better visualisation of global warming in last decade and a half ?

Very poignant Inow. Being that I live in an area hit heavily by wildfires the last couple years, it boggles my mind how the locals here still can deny global warming. Especially since they all admit it has never been this bad before. Yet they remain obstinate that the climate is not actually changing.

Caution, Falconer. The hick locals in your state may know better how inept forestry leads to fires.

When British Columbia burned, we blamed the combination of mountain pine beetle and reckless forest management, while acknowledging unusually warm winters enabled the runaway infestation which turned much of our forests into standing tinder. You point your finger to one cause only, you appear foolish, and you overwork your point.

A red spot on the skin is not evidence of an infection.
A bulge on the skin is not evidence of an infection.
A discoloration on the skin is not evidence of an infection.
A sore area with discomfort is not evidence of an infection.
A fever is not evidence of an infection.

When they all happen together and at greater frequency than ever before, however? The probability it's an infection is significantly greater. This is true even though each individual symptom could have myriad other explanations entirely unrelated to infection.


Now, speaking of the melting Arctic ice cover:
