And since it has been getting progressively colder for the past 8,000 years…
A reversion to Ice Age conditions will be the real climate catastrophe
Our current, warm, congenial Holocene interglacial has been the enabler of mankind’s civilisation for the last 10,000 years, spanning from mankind’s earliest farming to recent technology.
By Ed Hoskins
Each of the notable high points in the current Holocene temperature record, (Holocene Climate Optimum – Minoan – Roman – Medieval – Modern), have been progressively colder than the previous high point.
. . .
. . .
According to ice core records, the last millennium 1000AD – 2000AD has been the coldest millennium of our current Holocene interglacial.
The ice core record 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 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 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 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 Scare”.
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
• 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.
* Note from Ed Hoskins:
Other published Greenland Ice Core records as well as GISP2, (NGRIP1, GRIP) corroborate this finding. They also exhibit the same pattern of a prolonged relatively stable early Holocene period followed by a subsequent much more rapid decline in the more recent past.
