Then you have misunderstood everything you have heard.
then are natural processes, there are manmade processes. We can't control the natural ones.
The effects are additive. We have never in the history of the world had manmade processes that impact CLIMATE. We do now.
Human population, until the relative recent times, has never been very high. It is now 6 billion and the population has increased to this point geometrically.
Nature has always been very finely balanced. It takes very little to upset that balance. Someday, the #### that soon, in excess, may doom us, may be insufficient to hold the waters of our oceans to the planet and Earth will become a desert.
A variation of 1 degree Celsius has caused the widespread loss of astounding numbers of species. A small change in temperature in CLIMATE has caused catastrophic effects in human civilization.
The point is, we can, at great expense, live a lifestyle that will cause global warming to escalate beyond the point of balance. OR, we can chose a lifestyle, just as good if not better, than is cheaper to live, that will impact this balance.
Once the balance is upset, you can kiss mankind good bye. And once mankind is gone, mankind will no return.
So the real question is, why in the world would someone want to live a lifestyle based on outdated 19th century technology (oil) that costs so damn much, and for which we will wind up fighting every single person on the planet to get, when there are far cheaper, cleaner, MODERN technologies we can use?
