Tipping point interactions may also generate weakening cascades

The paper written by D. I. A. McKay et al. represents an interesting milestone for understanding the Earth's climate, and has stimulated public interest in such global issues. However, as researchers engaged in climatology and biome responses, we have some concerns about its findings. In this response, we posit five technical and conceptual arguments that question the assumptions of this work. McKay et al.'s paper provides a detailed analysis of the possible tipping points (TPs, with their associated thresholds) that the Earth may experience
