This seems like a very dogmatic statement to make. Especially when weighed with benefits of cheap energy and economic growth. A wealthier world can build the infrastructure to handle potentially negative effects of climate change.
The more extreme environmentalists and marxists say we should be engaging in degrowth, which would just result in a kind of feudal and static society, even more vulnerable to climate change. It should also be noted that the Little Ice Age in Europe was associated with scarcity and famine, while the Roman Warm Period was associated with golden ages of several civilizations across the world.
