2026 State of the Climate Report Shows a Planet Reaching Its Limits
The seventh edition of an annual report analyzing Earth’s “planetary vital signs” indicates that Earth systems are rapidly destabilizing, some at an accelerating rate.
The report, published today in BioScience, analyzed 16 of these signs, including greenhouse gas emissions levels, ocean heat content and acidity, the mass of major ice sheets, the number of hot days, Earth’s surface temperature, and more.
