Climate change may prevent contact with alien civilisations

3. Did you know climate change cannot be a problem, because no-one from the future has come back

to tell us to stop?

From that highly intellectual site The Discussionist:

The question liberals are afraid to answer

Question: If climate change, or global warming, or whatever you want to call it, is real and will destroy humanity, then WHY hasn't someone come from the future to stop it before it happens?

Answer: If climate change would destroy our civilization, it would have never happened in the first place, because someone would've come back in time to prevent it. "Scientists" say we're too late to stop it, obviously if climate change turned out to be a big deal, someone would've stopped it already.

Conclusion: Climate change is either A. Not real or B. Nothing to be conserned about.
