I read your link, and my biggest disagreement with it is that it (a) basically uses a very flimsy strawman argument that mischaracterizes the other side and (b) its conclusion is baffling and illogical.

Of course the reason we should fight global warming is that it will have huge deleterious effects on humans that are avoidable. Yes, I agree, "the planet" will continue with or without us, but most people would prefer the "with us" option.

Finally, you end with "All we are doing is making the earth more suitable for humans to live, that’s it." What?? Tell that to the billions of people that live along the coast, or say anyone that lives in Bangladesh.
