Understanding Climate Change and the role humans play in the process

In The Beginning

The Earth has been much warmer and much colder than it is today.

There was a time when a hippopotamus bathed in a lake in Wales, a time when the entire Earth was a snow ball.

Long before Australopithecus walked the Savanna of Africa, the climate of the Earth had gone through numerous changes. Ice Ages, hot spells, times of extreme volcanic activity, times of raging rivers.

There were tiimes when the air teemed with life, times when the only life was underground.

All these changes happened millions of years before a man lit a fire.

The Past Few Thousand Years

The Earth as been emerging from the last ice age, which occurred about 15,000 years ago.

The Pleistocene period, (going back about 2 million years) was dominated by repeated glaciations, after the relative stable period in the Miocene and Pliocene eras.

During the past million years until about 12,000 B.C.E. much of the Earth was covered in Ice, sometimes 30% of the Earth.

The ice ages had major impacts on the fauna and flora. With each advance of the ice, large areas of the continents became totally depopulated. Plants and animals moved southward, trying to keep in front of the advancing glaciers.

Major extinctions, mammoths, mastodons, saber-toothed cats, glyptodons, ground sloths, Irish elk, cave bears, and short-faced bears, began late in the Pleistocene and continued into the Holocene. (Present Day)

Neanderthals, a relative of modern humans also became 'extinct' during this period Between 50 and 30 thousand years ago the Neanderthals ceased to exist.

Some scientists postulate they intermarried with the branch from which modern humans developed as they left their homes for warmer climes, for until the dawn of the Holocene, much of Europe had become uninhabitable, buried under ice.

Warming Up

Human civilization, in its most widely used definition, dates entirely within the Holocene. This period begins about Twelve Thousand Years Ago. The Earth was warm enough for permanent cities to be created, (no more rushing up to escape the heat or down to escape the cold).

During the Holocene the climate has been fairly stable. Ice core records show that before the Holocene there was global warming which ended that last ice age.

There has been a 'mini-ice age' which went from mid 1600s to learly 1900s, during which the Thames froze, as did the Hudson River and Niagara Falls.

The question is; What is the 'Normal' range of Temperature for Earth?

In the Past 500 years

The Earth was warmer up to about 500 years ago. We know this from the voyages of the Vikings in open boats, and their discovery of a 'Vinland' where grapes grew.

We know a cooling took place around the voyages of Columbus, considering the way the people dressed. (Try walking around in Armour in Jamaica in even the 'winter' when it's over 80o, and you'll be parboiled in about thirty minutes).

We know this cooling continued up until the early 1900s when Niagara Falls froze solid.

Hence within 900 years, the area which had grown grapes was so cold that a massive water fall would freeze.

If we consider the period of year 1000 'normal' than the Earth has been suffering Global Cooling. This Global Cooling is just beginning to end, and it will take a few more years for the Earth to warm up to the level the Vikings enjoyed.

Rubbing your nose in it

This is a photograph taken on the 17th of February 2015 of Niagara Falls.

As you may notice, it is frozen. Tourists are bundling up, braving snow and blizzards and the coldest temperatures on record to see it.

Yet, people still believe in Global Warming. Despite the record breaking cold, despite the unprecedented snowfall, the human brain is still under the control of the 'Global Warming' posse.

Global Warming?

In the 1970s the expectation was that the Earth was 'due' for another Ice Age. Scientists had measured that every 12k years; hence 2000, was 'ripe' for an Ice Age.

Sometime during the past forty years the idea changed from Global cooling to Global warming.

The possibility that the cooling period (the mini-ice age) would cause sea levels to drop, and land in the northern hemisphere would cease being productive buried
under permafrost, worked on the 70s mind, but is ignored today.

Accepting the mini-ice age as the 'base', ignoring the evidence of climate from the writing of the Bible to the voyages of the Vikings, the idea is that the Earth is unnaturally warming and people are to blame!

Human Pollution

When a factory dumps waste into a river, that is human pollution. When a forest is cut down, that can be blamed on people. Considering that during the mini-ice age people burnt wood and coal and the Earth continued just as cold, and that now that they use a bit less polluting gas, oil, solar, etc. and the Earth is warming, can we really blame humanity that the Earth is apparently getting warmer?

I say apparently, as blizzards in November are rather unusual, as airports being closed due to the arrival of an early winter, are mentionable, as we recognise the current condition in France, Germany, etc. as not 'normal'

The extreme weather of 2010 pales beside the winter of 2012 where hundreds of people have frozen to death all across Europe, and Rome is blanketed in snow.

Further, the latest information recognises that the Ice Caps are far more resistant to
warming than originally thought.

But then again, what is normal? Grapes growing in Canada or a frozen Niagara falls?

It seems..

Considering the current hysteria over Global Warming, it might be time to take a deep breath, and look back over 12,000 years of human history and try to ascertain what the Norms actually are.

If you look at what Roman soldiers wore and compare it to how the Conquistadors dressed, if one notes that most of the older cities are currently inland, (Vikings buried their dead near the sea; many of the graves are now five miles inland might give you a good guesstimate the kind of climate they experienced).

One might begin to imagine the 'Norms' scientists tend to accept might actually have be aberrations, a period of unusual Global Cooling which is just beginning to abate.

Surely it is. I can only summarized this in two words "TOO MUCH!". Too much is put in it, and too much is taken from it.

Kaylar, A wonderful read. I remember the great scare of global cooling in the 1970's.
Do not get me wrong...
I do believe we need to take care of our planet but, we also need to have cooler and more logical heads about it all.
Great read!
Thank you for sharing.:)

I do think people are responsible..
even if not for global warming, for ruining much of the planet.

Thanks Denise; most people are totally ignorant that the exact same panic happened in 1970, but when the other way. It is like Orwell's 1984; where one reduces the ration of chocolate and claims to increase it.
In 1970 everyone was expecting a new ice age. in 2010 they are hysterical about global warming.
The joke is, if the Earth does warm that would free up vast acreage in Canada and Russia for planting. Meaning an increased food supply.

Marc, if you walk along the beach here you will find hundreds of thousands of plastic bottles...sure...human. And if humans had the brains of a sloth they'd fill and sink the bottles to make a reef to protect the coast.
That's all it would need to protect Harbour view...about one hundred - two hundred feet off shore, fill and sink the bottles.
But they don't. The garbage island in the Pacific...that is human caused. And can be human solved.
But humans can't stop a volcano from erupting; no matter how many virgins they toss in.

Hi,
I have liked this article, so decided to reference it in my article “Role of Biotechnology in Metereology/Climate Change”.

Its link is

I hope you are fine with it. If you want any other of your article to be added into my articles, do inform me.

Bye

For some reason that has not been fully revealed we are to believe in global warming despite the evidence to the contrary. One would think that the bitterly cold and quite long winters the Northern Hemisphere has been suffering would prod even a sluggish brain to doubt the postulate.

Hi kaylar,

I appreciate your concern for the green planet.

I join you in promoting these wonderful ideas for a better future.
