Thanks for thought-provoking article:
1) Apparently, we survived the Cretaceous Thermal Maximum 90 million years ago (when temperatures rose 14 degrees F and CO2 was 1,000 ppm, only to be moderated by Milankovich Cycles, glaciation and possibly plate tectonics).
2) To put into perspective, we are coming out of the Quaternary Glaciation (beginning 110,000 yrs ago, ending 15,000 yrs ago) so we might say there is a combination of human sourced CO2 & a natural warming cycle. I wrote about this thusly:
3) I believe we need to transition to clean energy, and away from fossil fuels (for reasons of climate change and beyond). However, there is the problem of natural methane release due to glacial retreat (and warming). The best way to prevent escape is to "volatilize" (ie burn), perhaps via some future carbon capture device.

4) As Bill Gates says, we'll probably need to convert to clean energy AND prepare to relocate. He doesn't believe in some of the more dire predictions, but also believes some of the warming effect is beyond control. I tend to agree.
5) Since a large part of the natural cycle involves phytoplankton CO2 usage due to minerals exposed by glacial retreat, perhaps the "seeding" of oceans with minerals (to accelerate) a possible solution.
6) You alluded to habitat destruction, an overlapping, but largely separate problem from global warming. This may not be solved by clean energy, perhaps only by reduction in human population, or drastically changing land-use patterns? Does this ironically mean that a global warming return to the Upper Cretaceous (when dinosaurs & others thrived on a lush, tropical planet at 1000 ppm CO2) while pushing a decimated human population north to the Arctic might be a good thing? (certainly a possible futuristic sci-fi plot)
