A new annual climate assessment found that seven of Earth's 16 monitored climate indicators have reached record highs, including sea levels and greenhouse gas concentrations.
Researchers said that current warming trends put Earth on track to exceed 3.6 degrees Fahrenheit (2 degrees Celsius) — the benchmark intended to avoid the worst damage — before 2050.
Here's what to know
Published Oct. 14 in the journal BioScience, State of the Climate is the annual report that tracks the Earth's "vital signs" such as atmospheric pollution and tree cover loss caused by wildfires. According to Time, the report concluded that "Earth's climate system is moving deeper into uncharted territory."
Not every indicator has hit a record yet, but the report said some are beginning to accelerate or change abruptly, including ocean heat and the amount of land burned by wildfires.
In the report's estimate, the warming rate rose from about 0.09 degrees Fahrenheit (0.05 degrees Celsius) per decade between 1880 and 1970 to around 0.65 degrees Fahrenheit (0.36 degrees Celsius) per decade between 2010 and 2024.
That acceleration also raises the chances of feedback loops and climate tipping points that could trigger further changes, some of which are irreversible.

The report warned "Earth's life-support systems are being pushed beyond stable limits," with changes "unfolding faster than our ability to respond."
More background
The report arrived after a year marked by severe heat and fire events around the world.
July 2026 set a heat record for the contiguous United States, as well as ocean temperatures. Europe endured two consecutive heat waves that preliminary reports linked to an estimated 35,000 excess deaths. Several regions — including Utah, Ontario, France, Spain, Britain, and Belgium — either recorded or were on track for some of their worst wildfire years on record.
The researchers noted that while no single weather event can be attributed solely to climate change, their body of research shows that a hotter planet is making extreme weather more intense, increasing the odds of dangerous heat, fires, and other disruptions that threaten public health, infrastructure, and everyday life.
The planet already crossed a troubling threshold in 2025, when researchers said Earth passed its first climate tipping point as warmer oceans, acidification, overfishing, and pollution combined to drive coral bleaching and mortality.
What's being done?
The report did highlight some measurable progress. Low-carbon sources generated about 43% of the world's electricity in 2025, while solar and wind energy consumption rose by roughly 18%.
At the same time, carbon pollution remains the instigator of the worsening trends. Fossil fuel use increased 0.9% in 2025, with oil, coal, and gas all reaching record highs. Annual energy-related carbon dioxide emissions also topped about 45.2 billion tons (41 gigatons) for the first time — roughly the annual pollution from more than 10,800 coal-fired power plants.
Time also noted that the war in Iran reflected how dependent the world still is on non-renewable energy sources and helped spark a global green energy boom. Rapid clean-energy growth alongside record dirty energy use helps explain why so many climate indicators are still moving in the wrong direction.
Cutting carbon pollution alone is no longer enough. The authors also pointed to adaptation strategies that include shifting toward plant-based diets and restoring mangroves to help shield coastlines from storm surges as communities adjust to a warming world.
The report concluded, "We are witnessing the rapid destabilization of the Earth's climate system," adding, "This is no longer a warning for the future; it is a diagnosis of the present."
