Sunlight at Earth's surface has surged since the 1980s. Germany's Potsdam station shows 15 more W/m² of solar energy reaching the ground than during the 1970s dimming era. The Netherlands, Switzerland and Japan all show the same trend. Austria shows even more: 23 extra W/m². It's called 'global brightening.' As air pollution dropped, the atmosphere cleared and sunlight flooded back in. That increase in surface radiation is 10 times larger than the forcing from CO2 over the same period. In short: the air got cleaner, the sunlight stronger and the land a little warmer. The data say so, the physics say so, it's only the narrative that doesn't.

Nice data. Can you provide more sources please so I can look into this further?
