If Nature were to draw a map of the world, what would it look like? One Earth presents a novel biogeographical framework called Bioregions 2023, which delineates 185 discrete bioregions organized within the world's major biogeographical realms.

Berkeley Earth, a California-based non-profit research organization, has been preparing independent analyses of global mean temperature changes since 2013. The following is our report on global mean temperature during 2021.

A new report has found that by 2025, the world must remove 1 Gigatonne, or 1 billion tonnes, of carbon from the atmosphere to keep global warming within the Paris Agreement target of 1.5°C. However, projects in development will remove only a fraction of this. The report says, “Without action to deliver 1 Gigatonne (Gt) of negative emissions globally by 2025, keeping global warming within the Paris Agreement target of 1.5°C cannot be achieved.”

The climate crisis is causing ancient permafrost to thaw, which could unleash viruses and bacteria that have been dormant for thousands of years, presenting a potentially catastrophic risk to humans and ecosystems alike.

A new study has found that if greenhouse gas emissions are not curbed urgently, a third of endemic species on land and half in the sea will become extinct, causing a collapse of biodiversity. According to the study, 92% of all endemic species on land and 95% of those in the ocean will decrease in numbers or even disappear under current emissions levels, which will increase global temperatures by 3 degrees Celsius by 2100.
