Modus Ponens/Tollens and Naomi Klein

I was interested to hear Naomi Klein giving a rather long-winded account of how some groups in America reject the very idea of global warming because they see that dealing with reality would mean abandoning cherished dogma about the distribution of the surplus......aka "economics' (vulgarly said)...

In a time when the ruling class is determined to destroy public universities, and whereas Philosophy Departments are also a victim....

IT is worth pointing out that were knowledge of baby logic more widespread--and baby logic is taught in Philosophy Departments at public universities--Klein might have simply said

What's modus ponens to one is modus tollens to another.....

Modus Ponens
If anthropocentric climate change is real Then we need to change our economic system.
Anthropocentric climate change is real.
Therefore, we need to change....

Modus Tollens
If a.c.c. is real, then we need a new economic system.
We don't need a new economic system.
Ergo, climate change is not real.
