ABSTRACT
It is debatable how much climate change we can live with. It is debatable whether we are close to the tipping point that leads to catastrophe or not. It is also debatable how much of our economic resources should be devoted to stabilizing or reversing humankind’s growing carbon footprint. What is not debatable is that the time for debating is over. We must start dealing with facts. The time for action has arrived. If we care about the future of our children and grandchildren, we must stop debating and start building.
