The doughnut-shaped framework of social and planetary boundaries (the ‘Doughnut’) provides a concise visual assessment of progress towards the goal of meeting the needs of all people within the means of the living planet1,2,3. Here we present a renewed Doughnut framework with a revised set of 35 indicators that monitor trends in social deprivation and ecological overshoot over the 2000–2022 period. Although global gross domestic product (GDP) has more than doubled, our median results show a modest achievement in reducing human deprivation that would have to accelerate fivefold to meet the needs of all people by 2030.

The global economy could face a 50% loss in GDP between 2070 and 2090, unless immediate policy action on risks posed by the climate crisis is taken. Populations are already impacted by food system shocks, water insecurity, heat stress and infectious diseases. If unchecked, mass mortality, mass displacement, severe economic contraction and conflict become more likely.

Global risk management for human prosperity

A global consortium committed to understanding and addressing the impact of global environmental change on human health : The Planetary Health Alliance is catalyzing a global movement to create a livable future for humanity and the rest of life on Earth for generations to come by regenerating Earth’s natural systems.

We need a new narrative that positions AI not as humanity's replacement but as our partner in planetary healing.

The climate crisis has entered a decisive phase. Delaying climate measures increases the likelihood of crossing tipping points. Political shifts are weakening international cooperation when unity is vital. Yet, the Planetary Boundaries offer a path to a stable and sustainable future.

2023 set a number of alarming new records. The global mean temperature also rose to nearly 1.5 degrees Celsius above the preindustrial level, another record.A team led by the Alfred Wegener Institute puts forward a possible explanation for the rise in global mean temperature: our planet has become less reflective because certain types of clouds have declined. The work is published in the journal Science.

The risk of Planetary Insolvency looms unless we act decisively. Without immediate policy action to change course, catastrophic or extreme impacts are eminently plausible, which could threaten future prosperity.

A new report from U.K. actuaries and climate scientists "shows a 50% GDP contraction between 2070 and 2090 unless an alternative course is chartered," said the lead author.​
