Climate change part of our history, adapt like always
BEFORE the verbal guns come out, I’m no denier, climate change is real. That said, climate change has existed since our planet first formed an atmosphere.
Many natural elements contribute to climate change – the Sun, Earth’s orbit, composition of the ionosphere and concentration of vegetation are some.
Throughout its history, our planet has been significantly warmer and colder than it is today, resulting in water levels that were higher and lower.
Our current focus is on carbon dioxide, CO2, an invisible gas credited with heating our planet.
CO2 is also essential for plant life which stores it, and in the process gives off oxygen, a gas essential to our life cycle. That CO2 storage in some cases resulted in the formation of the coal we burn today, freeing the CO2 stored in forests 300 million years ago.
The same applies to oil derived from organic materials, mainly concentration of dead animals.
We are justifiably concerned about our reefs yet the considerable sedimentary limestone deposits (calcium carbonate CaCo3) we use to manufacture cement are mostly made up of decomposing corals and shells. Today, reefs still survive. These are examples of natural occurring events where increased CO2 levels and warming played a part in laying down the fossil fuels and elements we rely on today.
Global warming has occurred naturally many times in history when we were not around to understand, observe or contribute to it. Somehow, through all this, our species evolved and spread across the planet.
Naturally occurring climate change will continue regardless of what we do, so do we fight against nature or learn from other species and adapt? What did Ice Age people think of a changing environment generated through global warming? Whatever the answer, obviously they adapted, otherwise we would not be here. BOB JANSSEN
