Climate system destabilizing faster, seven of 16 vital signs at record extremes, report says
Researchers led from Oregon State University say the climate system is becoming unstable quickly. The seventh annual report, published on 14 October 2026 in BioScience, puts warming at 0.36 degrees Celsius per decade since 2010.
A system losing stability
On 14 October 2026 the journal BioScience published the seventh annual state of the climate report, led by scientists at Oregon State University. The coalition has produced the report every year since 2019, and this edition tracks 16 planetary vital signs. Seven of them now sit at record extremes, and many others are moving in the wrong direction. The authors say the climate system is becoming unstable quickly, and they warn that the risk of crossing critical tipping points is rising.
William J. Ripple, a professor of ecology at Oregon State University and the lead author, framed the timeline in stark terms.
I think there is a real possibility that someone who is 30 today will see major changes associated with climate tipping points during their lifetime.
Record greenhouse gas levels
Carbon dioxide in the atmosphere reached 428 parts per million, the highest level in the last two million years and roughly 50% above preindustrial levels. The report found that carbon dioxide, methane and nitrous oxide all reached record highs in 2026. Global fossil fuel consumption grew 0.9% in 2025, and energy-related carbon dioxide emissions exceeded 41 gigatons for the first time. Livestock populations, a major source of methane, are growing by an estimated 700,000 head per week. In 2025, fires destroyed 10.8 million hectares, the third most on record.
Warming is accelerating
The warming rate has increased in each period the authors compared. Between 1880 and 1970 global temperatures rose by 0.05 degrees Celsius per decade, a rate that climbed to 0.19 degrees between 1970 and 2010 and reached 0.36 degrees between 2010 and 2024.
- 1880-1970
- 0.05 °C per decade
- 1970-2010
- 0.19 °C per decade
- 2010-2024
- 0.36 °C per decade
The Greenland and Antarctic ice sheets have shrunk to record lows, and ocean heat has reached record highs. The authors also point to the spread of ocean heat, which is likely to fuel a mass coral die-off, and they say reefs lose resilience with each successive bleaching wave. Ripple also warned about the coming El Niño, which is expected to strengthen by the end of the year and add heat to an already warmer planet.
A strong El Niño could temporarily push global temperatures even higher, while bringing additional heat and drought to vulnerable regions.
Calls for faster action
The authors argue that cutting emissions is still essential but is no longer enough on its own. They call for rapid adaptation measures, such as urban cooling and the restoration of wetlands. Ripple told the coalition's audience that renewable energy growth and battery storage advances are encouraging, but that they represent only one part of the transformation needed to stabilize the climate. He added that stabilizing the system depends heavily on large cuts in greenhouse gas emissions, effective adaptation and the protection of ecosystems. The report's stated goal is to monitor the planet's vital signs and push world leaders to stop carrying on with business as usual.
