You are here, 400,000 years later:
Source: EPA’s Climate Change Indicators (2014) and Petit et al. (2001). They are based on the Vostok Ice Core from Antarctica.
Over the last 400, 000 years, we’ve only touched this current and relatively short but pleasant (for thin skinned mostly hairless humans) temperature spike five times. This time (for the last approximately 10,000 years) we have barely made it back near the scheduled top temperature. Forget the 0.04% CO2 trace gas that gets accused of driving the climate to the current very ordinary peak. There are obviously much bigger and intense physics and thermodynamics at play looking on the four hundred thousand year scale.
What you are absorbing as the modern version of Climate Change Angst is carefully orchestrated by those who want to surgically frame the climate argument by arbitrarily scaling and smoothing the discussion window to match what these Merchants of Fear want you to believe.
For example, the Canadian public broadcaster CBC in September 2011 put up this alarming journalistic headliner: “Arctic sea ice hits record low!”. The opening paragraph purposely starts like this: “The amount of sea ice covering the Arctic is lower than ever before”. Turns out their “Ever Before” starts in 1972. Either the misdirect was intentional, or the CBC never bothered to apply a journalistic center line before publishing, or no one at the CBC knows or cares anything about real Physics, thermodynamics or appropriate scales to determine a bona fide climate trend, or maybe no one understands math or logic over there. Just saying.
You can find plenty of other examples of this skewed journalistic modus operandi, such as “Meteorological Year Warmest EVER!” , where ’Warmest Ever’ is only for the last 140 years that NASA kept records, when 140 years on the real climate cycle scale as a bona fide statistical trend is not even close; its lost in the data noise. Apparently margin of error or journalistic context has no place in such main stream pronouncements.
One doesn’t even have to understand the nuances of the chart’s gargantuan feedback / feed forward balance of primary forces that drive the ebb and flow of past climate change at scale, nor feel compelled to dissect the intense power of the historical trace climate cycles. The takeaway reality is that there are long (approximately 100,000 year +/-) cycle markers that recur in a periodic manner, just as reliable as summer, fall, winter, spring do for the tiny pinpoint limited lifetime scale of human understanding.
As you can see from the big picture, most of the earth’s timeline temperatures are spent in the frigid shallows and miseries of kilometers of glacial ice on top of current city locations such as Toronto. Why the gods of real climate physics choose to occasionally bless the earth with a brief interlude spike thaw to allow mankind to eat, reproduce and thrive for a while is still up for grabs.
Above all, don’t be hoodwinked into believing that the trace gas CO2 is the tipping point in this glacial story. It’s insignificant to the overall system dynamics at play, and in fact, actually lags somewhat behind the temperature rise and fall and even gets out of phase as you can see above. CO2 is just along for the ride on the same bus – and that’s a good thing; – It’s rise and fall with temperature is essential and critical to balance the mix for all life on this green planet, and incidentally, remains the circle of life mechanism of food and oxygen supply for the needy, dependent human bags of carbon based protein who need to eat, exhale CO2 and sporadically walk the planet during the warm spikes.
Don’t be fooled or become yet another willing parrot for “The Science of Climate is settled”. You are being played. That’s all that’s wanted; i.e., hand over your money and compliance, not your love.
