Extended Quote by Sebastian Sassi: 

"the "climate has changed before therefore we aren't changing it" argument isn't just in denial of basic physics, it's also logically the equivalent of saying that because beavers felled trees in the forest before mankind came along, there's no such thing as a lumberjack."

Notes: This is a very common myth proclaimed by climate change contrarians: "The climate has changed before therefore we aren't changing it."

Thus, it is very beneifical to have several rebuttal metaphors ready to debunk this, such as these similar bites: 

People die natural deaths. So murder can't exist?

Forest fires occur naturally, so arson can't be real?

"Climate is always changing... !"
