Yup! There's never been anything like this! It's unprecedented! we'll never recover from any of this because it's never happened before! We're all doomed, except, we're not.
It has happened before.
In the article, from a blog, the OP states the current Arctic Melt and attacks another scientist who cites anecdotal evidence of a warming of the arctic and resulting melting in the 30's.
By any scientific standards of today, pretty much just the observations of a guy on the next barstool.
One of the respondents in the comments section notes that the melt of this year could not possibly have been as extensive in any year over the last 3000 years because driftwood that is carbon dated to 3000 years has been released by the melting ice.
3000 years ago.
What was the CO2 Atmospheric concentration 3000 years ago?
What was the albedo change in the arctic ice caused by the coal ash from Chinese power plants 3000 years ago?
The point is, it was warmer in the past, during this Interglacial, and we are warming to levels we had cooled from in a geological blink of an eye.
This has happened before, it has happened quite recently, it was caused by something not connected to the Anthropogenic Emissions increase.
More data from the world of science undermines the propaganda issued by the Catastrophic Climate Change shills.

Temperature variations during the Holocene from a collection of different reconstructions and their average. The most recent period is on the right. Note that the recent warming is not shown on the graph.
