Yes, literally thousands of times on a wide range of issues. * Predictions that increased carbon in atmosphere would lead to higher average temperatures -> has happened. * Predictions that extreme weather events like "once in a hundred years" floods would become more common -> has happened. * Predictions that wildfire season would start earlier in the spring and end later in the fall -> has happened. * Predictions that we'd see reductions in glaciers and arctic ice -> has happened. * Predictions that we'd see a collapse in biodiversity and mass extinctions -> has happened. Scientists can't tell you exactly where an electron is and how fast it's moving, but they can still predict how it interacts with things around it.
