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.

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 presents an important perspective on the technosphere as an intertwined component of the human-Earth system in the Anthropocene.

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.

This study identifies a potential instability in the global carbon cycle driven by feedbacks between climate, weathering, and ocean chemistry, suggesting abrupt shifts under extreme perturbations. Although the conditions required are severe, the findings reveal that Earth’s carbon system may have multiple stable states, with implications for climate tipping points. The work offers a crucial theoretical framework for understanding past and future carbon cycle disruptions, making it highly relevant to geoscientific and climate research.

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.

Climate models are some of our best tools for understanding future changes, especially how likely it is that we accomplish the goal of the Paris Agreement to keep warming to well below 2.0°C. Recent updates to radiative forcing estimates from greenhouse gases and tropospheric aerosols result in an increase in projected warming, substantially reducing the likelihood that we will meet the goals of the Paris Agreement.

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 paper offers the first cross-regional synthesis of stakeholder perspectives on multi-hazard risk drivers across Europe, providing empirically grounded insights into how hazard interactions, vulnerability dynamics and disaster risk reduction measures evolve over time. By integrating qualitative methods with multi-risk governance analysis, it promotes context-sensitive and actionable disaster risk knowledge. Its findings are highly relevant to the geosciences community working on risk modeling and hazard interactions and are also of great interest for practitioners, policymakers and media focusing on disaster risk governance, climate adaptation, and societal resilience.

Understanding impacts of climate extremes holds enormous societal and economic value, and is a key step towards climate resilience and adaptation. Notwithstanding recent advances in the field, there are unique challenges which hinder progress beyond the current state-of-the-art. This paper outlines three key challenges and identifies opportunities to address them, providing a pathway to advance interdisciplinary and inter-sectoral research on societal impacts of climate extremes.

Broadly, there are two schools of thought with regards to the relationship between orbital cycles and Ice Ages: either the orbital cycles directly force the Ice Ages or the Ice Ages are an oscillation within the climate system that is phase-locked to the orbital cycles. Both of these schools of thought implicitly assume that the orbital forcing makes the climate system "forget" its initial state. Here, Verbitsky & Volobuev perform idealized ice-sheet simulations and show that the system doesn't "forget" its initial state. Furthermore, this system exhibits spontaneous periodicity changes. The authors argue that this behaviour depends on the memory duration of the climate system. Therefore, this work opens an important avenue to be addressed by future research, focusing on the length of the memory of the climate system.
