> We are on track to change the climate so abruptly that the species we depend on will not adapt quickly enough. Jellyfish, for example, might thrive. Large mammals like ourselves will not.

The notion that humans, as a species, will not adapt seems farfetched to me. Humans have perpetuated themselves in a wide variety of climates for thousands of years.

I don't say that to discredit concerns about environmental change, its impact on future populations, or its near term impact on existing individuals. All I'm saying is that arguments based on existential threats are not persuasive to me and they tend to be used to assert power over others than to mitigate risk or improve the lives of people on the earth today.
