Even without climate change - however caused - our unsustainable use of the planet's resources cannot continue indefinitely. Exponential population growth simply accelerates our trip to oblivion. Thus sustainable growth should be the focus.
What sustainable growth should look like is going to require some hard thinking, science innovation, cultural and behavioural change and an examination of what happiness is ;-)
Paradoxically, the one resource that we have that is sustainable (if fed and watered) is brain power. Everything else is just tools and materials. You can't be me, I'm taken
Which is part of the paradox of brain power here. It's a 10% inspiration, 90% typing the skin off your fingers deal.
