This briefing by Zero Carbon Analytics examines the concept of 'temperature overshoot'—where global warming exceeds 1.5°C to 2°C before returning to those levels—and the associated risks of triggering irreversible climate tipping points. It argues that while the chance of limiting warming to 1.5°C by 2100 is now 'virtually zero', minimizing the magnitude and duration of overshoot is critical to avoid catastrophic Earth system collapses. The document contrasts dangerous climate tipping points with 'positive socio-economic tipping points' that can accelerate decarbonization, while warning that reliance on carbon dioxide removal (CDR) and geoengineering introduces severe risks and does not replace the need for immediate, deep emissions cuts.

This report by the Climate Policy Initiative analyzes the economic viability of forest restoration in the Brazilian Amazon compared to cattle ranching. It proposes that a carbon price of US$ 20 per ton of CO2 captured via natural regeneration would make restoration more profitable than ranching, potentially capturing 16 Gt CO2 and avoiding another 32 Gt CO2 over 30 years.

This briefing by Zero Carbon Analytics prepares readers for the release of the IPCC's 6th Assessment Report (AR6) 'The Physical Science Basis'. It outlines major climate science developments since the 5th Assessment Report (AR5), focusing on human attribution of extreme weather, updated carbon budgets, refined climate sensitivity models, the role of non-CO2 greenhouse gases, and the complexities of net-zero and carbon dioxide removal.

This research paper analyzes Amazon deforestation as a large-scale collective action problem, focusing on the behavioral and institutional drivers that either hinder or facilitate conservation efforts to prevent a biophysical tipping point.

This research paper compares how the European Union, Hungary, Portugal, and Scotland incorporate high-end climate change (HECC) scenarios—those exceeding 4°C—into adaptation decision-making, finding that such scenarios are not routinely used because decision-makers perceive them as low-probability or distant events.

This research paper by the World Resources Institute examines the conflict between increasing food production to sustain a growing population and the conservation of ecosystem services under the pressure of climate change. It argues for a shift from managing ecosystems solely for food to a holistic approach that integrates food production with the maintenance of other nature-based services to avoid irreversible ecological tipping points.

This fact sheet summarizes the personal testimony provided by Dr. James E. Hansen on August 14, 2006, regarding climate change in the legal case of Association of International Automobile Manufacturers et. al. v. the Secretary of Vermont, Agency of Natural Resources et. al.

This report documents a scoping workshop held in Stockholm, Sweden, from September 26-28, 2011, to plan the Arctic Resilience Report (ARR). The workshop aimed to establish a science-based framework for assessing the risks of abrupt, potentially irreversible changes in Arctic social-ecological systems caused by interacting drivers such as climate change and social development. The resulting proposal, approved by the Arctic Council in November 2011, outlines a project to identify tipping points, evaluate resilience, and develop strategies for adaptation and transformation to inform decision-makers.
