The recent warming since the end of the Little Ice Age has been wholly beneficial when compared to the devastating impacts arising from the relatively minor cooling of the Little Ice Age.
Betting on a catastrophically cooling world
By Ed Hoskins
According to ice core records, the last millennium 1000AD – 2000AD has been the coldest millennium of our current Holocene interglacial. This point is more fully illustrated with ice core records on a millennial basis back to the Eemian period here:
Our current, warm, congenial Holocene interglacial, although cooler than the Eemian interglacial 120,000 years ago, has been the enabler of mankind’s civilisation for the last 10,000 years, spanning from mankind’s earliest farming to the most recent technologies.
Viewing the current Holocene interglacial on a millennial basis is rational. But sadly it seems that, driven by the need to continually support the Catastrophic Anthropogenic Global Warming hypothesis / religion Climate alarmists irrationally examine the temperature record at too fine a scale, weather event by weather event, month by month, or year by year.
From the broader perspective, each of the notable high points in the current 11,000 year Holocene temperature record, (Holocene Climate Optimum – Minoan – Roman – Medieval – Modern), have been progressively colder than the previous high point.
The ice core records from Greenland for its first 7-8000 years, the early Holocene, shows, virtually flat temperatures, an average drop of only ~0.007 °C per millennium, including its early high point known as the “climate optimum”. But the more recent Holocene, since a “tipping point” at around 1000BC, 3000 years ago, has seen temperature fall at about 20 times that earlier rate at about 0.14 °C per millennium .
The Holocene interglacial is already 10 – 11,000 years old and just judging from the length of previous interglacial periods, the Holocene epoch should be drawing to its close: in this century, the next century or this millennium.
Nonetheless, the slight and truly beneficial warming at the end of the 20th century to a Modern high point has been transmuted by Climate alarmists into the “Great Man-made Global Warming Alarm”.
The recent warming since the end of the Little Ice Age has been wholly beneficial when compared to the devastating impacts arising from the relatively minor cooling of the Little Ice Age, which include:
• decolonisation of Greenland
• Black death
• French revolution promoted by crop failures and famine
• the failures of the Inca and Angkor Wat civilisations
• etc., etc.
As global temperatures, after a short spurt at the end of the last century, have already been showing stagnation or cooling over the last nineteen years or more, the world should now fear the real and detrimental effects of cooling, rather than being hysterical about limited, beneficial or probably now non-existent further warming.
Warmer times are times of success and prosperity for man-kind and for the biosphere. For example during the Roman warm period the climate was warmer and wetter so that the Northern Sahara was the breadbasket of the Roman empire.
But the coming end of the present Holocene interglacial will eventually again result in a mile high ice sheet over much of the Northern hemisphere. As the Holocene epoch is already about 11,000 years old, the reversion to a true ice age is becoming overdue.
That reversion to Ice Age conditions will be the real climate catastrophe.
With the present reducing Solar activity, significantly reduced temperatures, at least to the level of another Little Ice Age are predicted quite soon this century.
Whether the present impending cooling will really lead on to a new glacial ice age or not is still in question.
As an interested layman, I would say that the betting is more heavily weighted towards a catastrophically cooling world rather than one that will be overheating because of the comparatively minor CO2 emissions from mankind.
