We present the 2026 update of planetary vital signs that track the state of Earth\u2019s climate system, alongside indicators of the human activities driving ongoing change. Of 16 climate-related indicators, seven are currently at record extremes. Several indicators also show evidence of accelerating trends or abrupt shifts, raising concerns about increasing climate instability, interacting feedbacks, and the growing risk of crossing critical tipping points. Human activities, particularly fossil fuel combustion, remain the dominant drivers of these changes. Despite the worsening trends, encouraging signs of societal changes are emerging, including the rapid expansion of renewable electricity and battery storage, although progress remains far below the scale and speed needed to stabilize Earth\u2019s climate system. Rapid reductions in greenhouse gas emissions, effective adaptation, ecosystem protection, and transformative societal change remain essential to reducing climate risks and securing a more resilient and sustainable future.<\/jats:p>","DOI":"10.1093\/biosci\/biag125","type":"journal-article","created":{"date-parts":[[2026,8,6]],"date-time":"2026-08-06T11:54:14Z","timestamp":1786017254000},"source":"Crossref","is-referenced-by-count":0,"title":["The
