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 research paper analyzes the internal dynamics and global positioning of the BRICS grouping amidst a shift in US foreign policy. It highlights the economic dominance of China within the group, the tension between the narrative of equality and actual power imbalances, and the group's commitment to maintaining an open global economy and climate agreements like the Paris accord despite internal rivalries.

This document is a preview of results from a book regarding the valuation of oceans and the economic impacts of action or inaction, focusing on the Pacific Ocean as a case study for the need for integrated regional policies to address multiple human-induced stressors.
