As far as climate change goes, I do believe it is real, but as to what extent is it caused by us humans is
Personally, I don't believe it is debatable, we have most certainly contributed causally to environmental warming across the planet through our fossil
fuel burning and dependence. Quite simply, 300 years of our fossil fuel burning has put into the atmosphere trillions of tons of CO2 that would not be
there from natural causes alone. Volcanoes, and natural forest fires caused by lightning strikes, for instance, do not in themselves put the amount of
CO2 into the atmosphere that pushes the planet into warming or cooling trends in the way we are seeing, nor do they cause permafrosts to melt and
release gargantuan amounts of methane from tundra and ocean floors.
If a caldera should erupt and continue to erupt for a certain length of time, then yes, it could cause a short cooling trend of a few years, but what
we are experiencing is a continual rising warming trend, year-on-year. Never in our species existence has there ever been the amount of CO2 in the
atmosphere as there is today, and there is no abatement to its continual input. Our fossil fuel burning is additional to natural CO2 production.
Mechanisms around the planet are quite able to cope with natural production of CO2 that finds its way into the various layers of the atmosphere.
Natural CO2 is taken out of the atmosphere into natural CO2 sinks where it gets stored or used and turned back into oxygen, Natural production of CO2
does not overwhelm the mechanisms the planet has for dealing with it, even though environmental pockets around the planet may suffer, and cause
hardships to life forms in those local environments.
However, the amount of CO2 we have added to the planet through our fossil fuel burning has to be factored in, and we discover that our CO2 addition
tips the scales, not only because of the amount we produce, but also because our continued input of CO2 in ever greater amounts does not allow for any
relief to the natural mechanisms dealing with it...we have saturated the carbon sinks, and there is nowhere else for the carbon to go, so it remains
in the atmosphere, trapping the heat of the sun within the narrow spectrum between terra firma and the sky, and because it is there, warming is the
The warming rises and eventually triggers feed-back loop mechanisms and cause runaway effects that themselves act as causes to other effects, and all
are detrimental to the stability of our environments, and their ability to sustain us comfortably. The real issue about global warming and climate
disruption is about environment, because the environment is what provides us with our food and the air we breathe, and for the last 300 years we have
been polluting them to such an extent that there are now areas around the planet that are not fit for many life forms habitation, including that of
our own species.
Over the coming years, the effects are going to worsen, and all we can do is to mitigate the impact of them, we cannot stop it now. Even if we were to
reduce our CO2 input the next 40 years will still see a rise in effects, as it takes that long for the effects to be felt. It's not about 'saving the
planet', that's a misnomer, the planet will be what it always has been...a planet, regardless of the climate. Environments around the planet will be
hit and become quite uncomfortable. Our problems are going to become compounded by many issues, natural and social and cultural and ideological, all
of which we are seeing today.
