Climate change fallacy

What fallacy would it be to suggest that since climate changed before the burning of fossil fuels means fossil fuels cant be causing climate change now?

Not sure it’s a non-sequitur given the assumed argument that precedes the fallacy, which is typically that burning fossil fuels caused global warming.

I think causal reduction is the better choice. Interestingly, I believe the post hoc and cum hoc  fallacies fall under that general umbrella (Dr. Bo can confirm), which is relevant to this debate in the following ways...

POST HOC FALLACY

“If you look at this graph (e.g. the infamous ‘hockey stick’), you can clearly see that global temperature increases after CO2 increases.”

CUM HOC FALLACY

“If you look at this graph (e.g. the infamous ‘hockey stick’), you can clearly see that global temperature increases as CO2 increases.”

For me, this raises the question of whether the counter-argument is some inverse of this fallacy?

ANTE HOC FALLACY?

”If you look at THIS graph, you can clearly see that global temperature increases  before CO2 increases.”

NON HOC FALLACY?

”If you look at THIS graph, you can clearly see global temperature increases when there is NO increase in CO2.”

Non Hoc Ergo Non Propter Hoc? :-)

Eat Meat... Or Don't.

Roughly 95% of Americans don’t appear to have an ethical problem with animals being killed for food, yet all of us would have a serious problem with humans being killed for food. What does an animal lack that a human has that justifies killing the animal for food but not the human?

As you start to list properties that the animal lacks to justify eating them, you begin to realize that some humans also lack those properties, yet we don’t eat those humans. Is this logical proof that killing and eating animals for food is immoral? Don’t put away your steak knife just yet.

In Eat Meat… Or Don’t, we examine the moral arguments for and against eating meat with both philosophical and scientific rigor. This book is not about pushing some ideological agenda; it’s ultimately a book about critical thinking.

Besides the general non sequitur ...

The failure in reasoning here stems from causal reductionism , or assuming climate change has a single cause (or multiple causes limited to only the single category of "naturalistic") and not entertaining the fact that causes can also be man-made. In essence, it is the failure to accept the possibility of other causes.

Yep, non sequitur.

Logical form (I should have done this before):

P1) Climate changed before the burning of fossil fuels

P2) We are burning fossil fuels now

C) Climate change cannot be because of fossil fuel burning

Conclusion does not follow.

However, I think causal reductionism is the better fit (see Dr Bo's comment) as it is more specific.
