Climate change and global warming specifically, or global cooling for that matter, is inevitable. The earth’s climate, is not a constant. What is happening today, has happened many times in the earth’s history and we, as a species need to be prepared for it this time, because the last time global warming occurred approximately 130,000 years ago, our species was in its infancy and we hadn’t built any of the conurbations of today. The city as we know it today, didn’t exist then and, as a species, we stand to be affected much more, than the last time the globe warmed up.

In its history, the earth has experienced many warming and cooling cycles, usually lasting thousands of years at a time. These warming and cooling phases, are determined by many cosmic and geophysical occurrences, ranging from the earth’s:

·Solar Inclination (Axial Tilt or also Obliquity); and

·Orbital Eccentricity; to

·Astronomical Precession

collectively known as the Milankovich cycles.

Today, the earth is once again in a warming phase, in what is known as the Holocene Epoch, which is a natural warming phase or called an Interglacial period, which has existed since the end of the Last Glacial Maxim and presumably commenced around 15,000 ybp. What this means, is that the earth has been naturally warming up since then and none of our industries, as we know it today, were even present then.

The previous Interglacial phase, most commonly known as the Eemian Interglacial, lasted approximately 16,000 years. It is estimated that it began around 133,000 ybp and peaked at 125,000 ybp. During this period, the polar ice sheets contracted and our sea levels may have been between 4 to 6m higher than what they are today. Anthropogenic Induced Global Warming is not the only contributor. The earth is naturally warming up.

The fact remains that our planet’s climate is not a constant, but rather in a constant state of flux. The earth’s climate will change and so it must. It is only part of the earth's natural cycles.
