Science tells us that planet Earth is approximately 4,568,200,000 years old. Science also tells us that the fossil record shows that Earth goes through massive heat and cold fluctuations, which are often several magnitudes greater than what the doomsday prophets are predicting if CO2 levels skyrocket and everything falls apart. Science also tells us that we've only been making semi-accurate readings of the Earth's temperature and other weather-related information for the past 1½ centuries, which is a mere 0.000003% of the Earth's age. That is why climate alarmists like to use phrases like "This was the coldest/warmest year on record," which is designed to sound scary, but any single year only represents a period that is 0.00000002% of global history. In other words, whenever someone says "This was the coldest/warmest year on record," they are deliberately misleading you with junk science, because the "record" is little more than a statistical blip that is re-interpreted when necessary to back up a pre-existing point of view and to manipulate public opinion. (e.g. "Numbers never lie, but liars always use numbers.")
Science also tells us that it is incapable of predicting weather patterns, which is why scientists here in Arizona couldn't tell us if we would have a Monsoon season last year (which we didn't), or if we would have a Monsoon season this year (which we did), or if we will have a Monsoon season next year (which is anybody's guess). In other words, most scientists - despite their years of study and academic accolades - are admittedly making nothing but educated guesses, and the only solid FACTS that we have are: the Earth is warming, as it has done in the past, and it will do in the future. After which the Earth will cool, as it has done in the past, and it will do in the future.
However, there is one additional point that I would like to make: I do not care whether climate change is real. From my perspective, someone would have to be a card-carrying idiot to disbelieve that humanity is leaving an indelible mark on the planet. There are currently 7 billion people on the planet, and we are consuming the Earth's resources faster than renewables can keep up, and that says nothing about the resources that are not renewable. Every day humanity discards millions of tons of garbage, pours millions of gallons of toxic filth into our water sources, and belches millions of pounds of toxic filth into the atmosphere. In short, we are killing the planet.
Let's say for the sake of argument that man-made climate change is real. In the grander scheme of things, it doesn't matter, because the planet is amazingly resilient and the climate will eventually bounce back from humanity's many transgressions. Our planet has survived asteroid impacts, global ice ages, super volcanoes, and mass extinctions. What we humans do or not do now is going to have little to no impact on where the Earth's temperature will be measured a century from now, and to disagree with that reality is pure folly.
However, there are regions of this planet that have already been rendered so toxic that life will NEVER grow there again, and there are several places where spending more than a few minutes in close proximity is fatal to anything that lives. With that in mind, climate change isn't the problem - pollution is. The earth can sustain a CO2 spike and a few extra degrees on the thermometer, but it CANNOT survive humanity poisoning everything out of existence.
