The paper is timely: there is growing interest in the development of approaches to model species distribution and the one presented in this paper is novel, simple, and efficient. The topic is of significance for a broad audience, from ecologists interested in theoretical aspects to conservationists. While the analysis has a regional scope, the approach is generalisable and may be applied elsewhere.

This paper examines multi-century consequences of climate change following a simulated reversal of emissions from the SSP3-7.0 (high emissions) scenario in 2100 to net zero in 2250. It demonstrates the potential for very long-term, major committed impacts of the ongoing anthropogenic greenhouse gas emissions.

This paper looks at constraints on future ocean heat uptake. The results suggest greater rates of 21st century ocean and atmospheric warming than previously assessed, calling into question methods using past warming to constrain future warming.

This study challenges the conventional wisdom that the commitment to an Earth System tipping point occurs as soon as a critical threshold is crossed. The authors show that the number of elements that would undergo tipping is severely reduced if the duration of exceedance of the Paris Agreement 1.5 °C threshold can be kept below a century. Furthermore, the analysis suggests that all tipping elements would be avoided if global warming over 1.5 °C is restricted to 30 years and peak warming is kept below 2.5 °C. Consequently, the duration of exceedance of tipping thresholds matters.

While there are many dystopian articles on post-catastrophic scenarios, rigorous, science-based analysis are limited. This paper will be a significant addition to the limited literature in this area and should have broader public and media interests.

This paper represents a state-of-the-art review of tipping points in the physical climate system. It should be of great value and use to inform the community about the current status of research on tipping points and global climate change.
