Seven planetary vital signs reach record extremes as climate worsens

Seven of 16 tracked planetary vital signs have reached their most extreme state ever recorded, researchers report.

Seven of 16 planetary vital signs have reached their most extreme state ever recorded, according to a study published Wednesday in the peer-reviewed journal BioScience. The markers include greenhouse gases, temperature, glacier mass, oceans, wildfires and the planet's energy imbalance. Researchers found that atmospheric carbon dioxide levels are now 50 per cent higher than preindustrial levels, whilst Greenland and Antarctic ice sheets have shrunk to record lows and ocean heat has soared to record highs.

The warming rate has accelerated significantly. From 1880 through 1970, the global average temperature warmed at about 0.05 degrees Celsius per decade. Since 2010, that rate has increased to 0.36 degrees Celsius per decade. CBS News reports that in July 2026 alone, ocean temperatures globally reached new heights, whilst carbon dioxide levels in the atmosphere are higher than at any time in the last 2 million years. The United States experienced its hottest summer on record, whilst heat waves in Europe killed an estimated 14,000 people.

Oregon State University researcher Bill Ripple, lead author of the study, described Earth's condition as 'serious and getting worse'. He warned that a strong El Niño occurring on top of a much warmer planet could push global temperatures even higher and bring additional heat and drought to vulnerable regions, with particular concern for coral reefs and tropical forests facing potential mass die-offs from ocean heating.
