World Wobbles Like It Used To Wobble

Those who are shocked to discover that climate actually changes are starting to worry that the world is beginning to wobble like it used to wobble before the ice age!

True to form, The Guardian (1) has picked up on some findings by NASA to assert what most educated people already knew – that climate is actually and always has been in a state of flux.

When the ice sheets and glaciers finally shrink dramatically from their present proportions, as they will do at some point unless humans modify and regulate the climate, we will no longer be in an ice age. Such change is normal and consistent with the geological record.

The current ice age began around 2.6 million years ago though we are currently in an interglacial or warmer phase of this ice age  (2). Human ancestor Australopithecus emerged long before the current ice age. These primitive proto-humans coped and evolved in a  world where ice sheets did not reach their current extents and managed to do so without advanced technology.

Modern humans, Homo Sapiens, appeared during the current ice age. Perhaps humans evolved due to the ice age and are genetically predisposed to living with ice on their planet. However, this does not really matter. Humans are the only life form on Earth capable of regulating the climate according to their own preferences. They are also capable of genetically modifying themselves to to suit climatic conditions. Either way, humans can and will survive any climate change that nature throws at them.

A new and interesting era for humanity is coming into being.

Climate Change Hysteria Strikes Again!

Yesterday, I read an article (1) in The Guardian about the dire threat to civilisation as we know it posed by Global Warming. Don’t get me wrong I know for a fact that Climate Change is real. I also know that it is highly likely that humankind is having an impact on our global climate.

What I don’t get is how people can know for absolute certainty whether this is a good or a bad thing. I also dislike the tone of the current debate and how dogmatic it has become. Things have got so bad that some on one side want to deny their opponents freedom of speech. Not only is this a danger to human rights, it is a danger to science.

The Guardian article (1) continues “February 2016 was likely the hottest month in thousands of years, as we approach the 2°C danger limit.” Notice the word “likely” which of course makes what is being said completely meaningless. I suppose it could be read as grudging acknowledgement that the facts don’t come out on any side of the argument.

It  (1) goes on to talk in terms of temperatures in “pre-industrial times” and of “the Arctic’s “warmest-recorded winter”. What part of the 200 thousand years that Homo Sapiens has walked the Earth is regarded as “pre industrial”? It should be all of it except the last few hundred years. What part of the pre-industrial period does the ‘Little Ice Age’ of the Middle ages represent? What does The Guardian make of the Mid Holocene Warm Period? There were no jet planes or gas guzzling humvees darting about back then.

Actual records began only a few hundred years ago, though these have been supplemented with evidence derived from ice cores. In geological terms records began only nanoseconds ago. During my days studying geography and geology at university timescales of millions  and not hundreds or thousands of years were the norm.

It is therefore probably too early to say whether any potential human influence is dangerous or beneficial. It could be that human influence has prevented the natural cooling of the Earth with all the impact that such cooling could have on things like food supply.

The current debate on climate change focuses on the last few hundred years of formal records. It focuses on the impact that human beings have made since the Industrial Revolution which also represents a period of a mere few hundred years.

The debate, if done honestly and without recrimination could lead to the development of technology that may ultimately allow humanity to actually choose an optimal climate.  We would then be in a position to live in a world that has never existed, a world of a stable and unchanging climate.

This would certainly make the Anthropocene the most unique and radical epoch of geological time. What wonders could follow? – the terraforming of other planets where the air is currently unbreathable and of expanding the reach of Gaia across the Galaxy? This could thus allow humanity to realise its ecological destiny and ultimate purpose.
