This is not how science works.
There is no single study that “proves” human-caused warming, just like there is no single study that “proves” gravity exists or that smoking causes cancer. Science doesn’t work by publishing one final, definitive paper that settles everything—it works by accumulating evidence from multiple independent lines of research, all pointing to the same conclusion.
We have direct measurements of CO₂ trapping heat. We have isotope analysis confirming that the additional CO₂ in the atmosphere comes from fossil fuels, not natural sources. We have decades of satellite data showing an increasing energy imbalance. We have observed long-term temperature trends that match the physics of greenhouse gases.
When every major scientific institution, every line of observational data, and every fundamental principle of atmospheric physics agree on the same conclusion, it’s not just an assertion—it’s the best-supported explanation we have.
Expecting a single study to “prove” it misses how science actually works.
