here's arctic temperature 1920 to 2017
there seems to have been a trough from about 1960 to 1980, and now we're back to the temperatures that prevailed around 1930 or 1940
Fluctuations appear to have been larger in the old days

Re: Global Warming - Impacts, Vulnerability, Adaptation
you can see from the graph that the fluctuations are sometimes below the average

Re: Global Warming - Impacts, Vulnerability, Adaptation
As you can see in your graph, those fluctuations move the average towards higher temperatures (it's a running average, not equal to that in my graph). As you noticed yourself, the amplitude of those fluctuations has been very high, which according to the author I quoted suggests that the "classical" models are unsuitable to model temperature in this system.

This is an inverse (ill-posed) problem.

my bad, 2017here's arctic temperature 1920 to 1917

Re: Global Warming - Impacts, Vulnerability, Adaptation
That was by the year 2100. It is ludicrous to imagine cars running on gas at the end of the century, so that sounds about right.
