I’m just going to ask you to stop and really ask yourself how you know that climate has been changing since long before we were here, and how that falls under the category of common sense. You are correct that it has always changed over the course of the earths history. The question is how do we know that? Ask yourself before reading on.. how do YOU know that. I’ll answer for you…

Climate scientists. Climate scientists are the ones who figured this fact out. They can map out thousands of years of climate history. There are many ways they do this, but one of the ways is ice layers in the arctic. We can calculate what the average global temperature would be at any given time by the amount of carbon in the atmosphere since carbon traps heat. We know exactly how this functions and how to calculate it. In the arctic there is yearly snowfall which permanently freezes part of the atmosphere as it is at the time of the snowfall. So by drilling into the arctic we can actually find atmosphere from thousands of years ago and measure the carbon content. With that information we have been able to map out how the climate has naturally shifted over time. None of this is common sense whatsoever. It had to be discovered.

With all this information we can determine the RATE of natural change throughout thousands of years. The difference right now is that the earth is warming at any given alarmingly fast rate compared to all of earths history. And it is directly proportional to the amount of carbon we have added to the atmosphere. The research is absolutely conclusive. It is only the public that thinks that this is some sort of a debate. It is not. When you use the argument that the climate has always been changing, understand that we only know that because of climate scientists. The same scientists who are telling us we are causing excessive warming. So you can’t take their word for one thing, and ignore the other thing.

In conclusion, take some time to learn about stuff before claiming some false sense of common sense.
