The report also argues that we are on the brink of more tipping points, with devastating risks for people and nature: the irreversible melting of polar ice sheets, the collapse of key ocean currents and the dieback of the Amazon rainforest \u2013 where the next COP (30) will be held in November.<\/p>\n\n\n\n
With global warming set to breach 1.5\u00b0C, the report \u2013 coordinated by the University of Exeter<\/a> and involving 160 scientists at 87 institutions in 23 countries \u2013 argues that countries must minimize temperature overshoot to avoid crossing more tipping points. Every fraction of a degree and every year spent above 1.5\u00b0C matters. Action to trigger \u201cpositive tipping points\u201d of self-propelling change \u2013 such as the rollout of renewable energy \u2013 now offers the only credible route to a safe, just and sustainable future, the report notes.<\/p>\n\n\n\n Professor Tim Lenton, from the Global Systems Institute<\/a> at the University of Exeter, said<\/a>: \u201cWe are rapidly approaching multiple Earth system tipping points that could transform our world, with devastating consequences for people and nature. This demands immediate, unprecedented action from leaders at COP30 and policymakers worldwide.\u201d<\/p>\n\n\n\n \u201cIn the two years since the first Global Tipping Points Report, there has been a radical global acceleration in some areas, including the uptake of solar power and electric vehicles. But we need to do more \u2013 and move faster \u2013 to seize positive tipping point opportunities. By doing so, we can drastically cut greenhouse gas emissions and tip the world away from catastrophic tipping points and towards a thriving, sustainable future.\u201d<\/p>\n\n\n\n Professor Hugues CHENET<\/a> and Silvia MONTAGNANI<\/strong>, both from I\u00c9SEG & University of Lille CNRS UMR 9221 \u2013 LEM, have together contributed with other experts to three chapters in the new report which focus on: the governance r<\/strong>equired to prevent Earth system tipping points; the topic of impact governance<\/strong>; and tipping point risk assessment<\/strong>.<\/p>\n\n\n\n The first Global Tipping Points Report published<\/a> in 2023 highlighted that prevention should be the core goal and logic of a new and urgently needed global governance <\/strong>agenda.<\/p>\n\n\n\n Source : Global Tipping Points Report (Chapter 1.2 Governance to prevent Earth\u00a0system\u00a0tipping\u00a0points).<\/em><\/p>\n\n\n\n In the latest report, the experts argue that the risk of activating tipping processes exists at current levels of warming and increases with every 0.1\u00b0C and every year of overshooting the globally agreed goal of 1.5\u00b0C. In addition, current climate mitigation measures are not sufficient to prevent tipping events; they need to be accelerated and coupled with measures addressing non-climate drivers, such as deforestation of the Amazon rainforest.<\/p>\n\n\n\n In particular, Hugues CHENET and Silvia MONTAGNANI insist on the crucial role of finance, which is the focus of their research \u201cIt is very clear that financial institutions need to urgently cease supporting the destabilization of the Earth through the huge financial flows that feed harmful activities such as fossil fuel extraction or deforestation. A reallocation of financial capital from (particularly in wealthy economies) banks and investors, must now contribute to re-stabilizing and restoring ecosystems.\u201d<\/p><\/blockquote>\n\n\n\n The researchers argue that societies need governance efforts that anticipate and prepare for the specific impacts of Earth system tipping points before tipping points are crossed \u2013 these impacts differ from the observed and expected impacts of climate change.<\/p>\n\n\n\n Source : Global Tipping Points Report (Chapter 1.3 Impact governance for Earth system tipping\u00a0points)<\/em><\/p>\n\n\n\n Governments should therefore assess and reduce vulnerability to the impacts of Earth system tipping processes, build resilience, and include tipping impacts in climate adaptation policy and planning and related policy domains.<\/p>\n\n\n\n Governments, intergovernmental organizations, economic and financial actors should also integrate Earth system tipping points into risk assessments across scales.<\/p>\n\n\n\n The chapter on risk assessment provides an assessment of the systemic risks Earth system tipping points pose to human societies and ecosystems across all global regions, introducing a framework for risk evaluation that addresses the fundamental inadequacies of traditional approaches.<\/p>\n\n\n\n Notably, the researchers argue that Earth system tipping points have huge impacts that demand further research and that all regions and billions of people face major impacts from earth system tipping points. They also argue that regional vulnerabilities highlight extreme inequalities for example in terms of certain regions\u2019 preparedness for the risks they face.<\/p>\n\n\n\n Source : Global Tipping Points Report (Chapter 2.4 Earth system tipping point risk assessment)<\/em><\/p>\n\n\n <\/p>\r\n\t\t <\/p>\n Additional information and full report<\/p>\n <\/p>\n The full report can be\u00a0viewed here<\/a>.<\/p>\n <\/p>\nAction required from leaders at COP30<\/h2>\n\n\n\n
