Climate has never been static, multiple ice ages and global warmings in between. Whilst one cannot deny an increase in Greenhouse gases, massive increases have happened in the past with volcanic eruptions, impacts etc. Krakatoa precipitated a drop in global temperature in Victorian times with human casualties due to related very cold winters. The earth, whilst on a journey round the sun is also on a journey round its own inclined axis due to wobble and the orbit around the sun has eccentricities. All of these peturbations, lead to climate maxima or minima every 43,000 years or so apparently. The truth is we know what the atmosphere is comprised of but not where we ar, nor the effect of a multiple wobbling orbit. Its wise to be careful and control our consumption of resources.
The last ice age ended 12,000 years ago before that, much of the northern hemisphere was uninhabitable and in theory prevented the 'Clovis' people accessing the US via the link to the (now) Soviet Union. There was the tunguska air blast meteor explosion and the more recent 2013? one (you tube).I think a violent eruption in Iceland (overdue) will sort the problem as it will drop the global temperature by a good few degrees if its a big bang and lasts. Then there is always the meteorite impact - the one before the Tunguska blast destroyed 93 % of all the animal species on the earth (Younger Dryas)
Younger Dryas, also called Younger Dryas stadial, cool period between roughly 12,900 and
11,600 years ago that disrupted the prevailing warming trend occurring at the end of the Pleistocene Epoch (which lasted from
2.6 million to 11,700 years ago).

So are we obssessing over the most dangerous prospect to end life on earth - I dont think we are there are things far more dangerous and all likely to reduce global warming.
However, as with all aspects of modern society I do believe we are obsessing and hand wringing to excess.
Stop breeding and start living !
Another and final thought;
Though Krakatoa’s is far from the most powerful volcanic eruption in history (the eruption of nearby Tambora in 1815, for example, measured a 7 on the VEI), it’s arguably the most famous. Its 1883 eruption became the first truly global catastrophe,
thanks to the recently installed worldwide telegraphic network, which instantly broadcast news of the eruption all over the world.
