GLOBAL TIPPING POINTS REPORT - 2025

GLOBAL TIPPING POINTS REPORT 2025 - Summary

Bad climate news is everywhere. Africa is being hit particularly hard by climate change and extreme weather, impacting lives and livelihoods. We are living in a world that is warming at the fastest rate since records began. Yet, governments have been slow to act.

Why is the Trump Administration trying to kill a small space science institute in New York City? Explanation begins with Galileo’s method of scientific inquiry and ends with the role of special interest money in the United States government. Galileo improved the telescope, allowing clearer observations of the planets and the Sun. Galileo differed from his peers, as he was unafraid to challenge authority. He claimed that the world should be understood based on observations, and he spoke directly to the public. He obtained philanthropic support for his observations and openly described the conclusion that Earth was not the center of the solar system – Earth revolved around the Sun.

We are on the brink of an irreversible climate disaster. This is a global emergency beyond any doubt. Much of the very fabric of life on Earth is imperiled. We are stepping into a critical and unpredictable new phase of the climate crisis. For many years, scientists, including a group of more than 15,000, have sounded the alarm about the impending dangers of climate change driven by increasing greenhouse gas emissions and ecosystem change (Ripple et al. 2020).

Scientists now fear that there is little more than five years left to prevent irreversible climate damage and stark changes to the Earth’s weather patterns from global carbon emissions, Minister for Climate Eamon Ryan has warned.

The renowned US scientist’s new book examines 4bn years of climate history to conclude we are in a ‘fragile moment’ but there is still time to act

As the northern hemisphere burns, experts feel deep sadness – and resentment – while dreading what lies ahead this Australian summer

A Belgian climatologist surveys the wreckage of his hometown. Pierre Ozer has been expecting these floods for decades.

Given the circumstances, Scientific American has agreed with major news outlets worldwide to start using the term “climate emergency” in its coverage of climate change. Journalism should reflect what science says: the climate emergency is here.

Editor’sNote: This essay by esteemed scientist James Hansen is a hybrid ofthe books’ foreword and an independent treatise on the accelerated warming of the planet

1.5 °C scenarios reported by the Intergovernmental Panel on Climate Change (IPCC) rely on combinations of controversial negative emissions and unprecedented technological change, while assuming continued growth in gross domestic product (GDP). Thus far, the integrated assessment modelling community and the IPCC have neglected to consider degrowth sce- narios, where economic output declines due to stringent climate mitigation. Hence, their potential to avoid reliance on negative emissions and speculative rates of technological change remains unexplored. As a first step to address this gap, this paper compares 1.5 °C degrowth scenarios with IPCC archetype scenarios, using a simplified quantitative repre- sentation of the fuel-energy-emissions nexus.

The number of countries announcing pledges to achieve net zero emissions over the coming decades continues to grow. But the pledges by governments to date – even if fully achieved – fall well short of what is required to bring global energy-related carbon dioxide emissions to net zero by 2050 and give the world an even chance of limiting the global temperature rise to 1.5 °C.

The framing of climate change, in particular, as something that wouldn’t be an issue if “we” had all just made better consumer choices has been persistent and effective. Every Earth Day, we’re bombarded with tips about how to minimize our personal carbon footprints; meanwhile, it’s 2021 and the GOP is still suggesting tree-planting as climate policy.

1.5 °C degrowth scenarios suggest the need for new mitigation pathways

EU leaders are focused on the spectacle of arriving at the US climate summit on Thursday (22 April) with an agreement on the EU climate law and 2030 target, but risk sacrificing the quality of the legislation, argue Adélaïde Charlier and Chloé Mikolajczak.

The latest report from the Climate Council of Australia, Aim High, Go Fast: Why Emissions Need to Plummet This Decade, lays out the science behind the necessity of urgent near-term climate action. The diagnosis is in, now the treatment must be ramped up with a greater sense of urgency than ever before, and we have to do it in the next 10 years.
