US EditionScientists Looked Back in Time to Find the First Signs of Human-Caused Global Warming. It’s Far Earlier than Previously Thought
- Benjamin D. Santer and colleagues published a 2025 study showing detectable human influence on climate as early as 1885 in the stratosphere.
- The study used historical data, theory, and climate models to predict stratospheric temperature changes starting in 1860 amid rising carbon dioxide levels.
- Researchers found that a human-caused cooling signal in the upper atmosphere would have been visible with today's technology within 25 years of 1860.
- Gabi Hegerl emphasized that the human influence on climate could have been identified rapidly, highlighting how early the signals of human-driven climate change would have become apparent.
- These findings suggest that earlier detection could have informed climate mitigation, while current budget cuts threaten essential monitoring programs.

Human-caused stratospheric cooling may have been detectable as early as 1885
A small, multi-institutional team of climate scientists has found evidence that human-caused impacts on the stratosphere began earlier than previously thought. In their study, published in the Proceedings of the National Academy of Sciences, the group used observational data, environmental theory and computer modeling to create simulations depicting the state of the stratosphere to a time just after the dawn of the industrial age.
Fingerprint of human-caused global warming was likely detectable 140 years ago, far earlier than previously thought
The human fingerprint on global warming was likely evident in Earth’s atmosphere far earlier than previously thought—even before the invention of modern cars, a new study says.
People were wrecking the climate 140 years ago — we just lacked the tech to spot it
Models suggest that human-caused global warming would have been detectable in the 19th century with today's know-how. Models suggest that human-caused global warming would have been detectable in the 19th century with today's know-how.

We've been affecting the climate far longer than we thought...
Scientists believe we have been affecting the planet’s climate for more than 140 years! A major new study in Proceedings of the National Academy of Sciences reveals that human influence on Earth’s climate can be traced as far back as the late 1800s—decades earlier than commonly assumed. Using modern climate models in a historical “what-if” scenario, researchers explored how accurately early temperature measurements could have picked up signs of …
By burning fossil raw materials, we release large quantities of greenhouse gases and thereby change the global climate. But from when did these emissions have measurable influences on the climate system for the first time? Researchers have now approached this question by means of a model simulation. If people had had today's measuring methods available in the 19th century, they would have [...] Der Beitrag Mensch veränderte Atmosphere schon im 1…
