Climate change is known to be a highly complex problem. To better understand the evolution, scientists need to study numerous and complex processes. In the "Climate Update" series, we present various aspects. In this episode, Bernd Fuchs explains why the earth is getting darker and what that means for global warming.
In the video: Climate update with Bernd Fuchs about the decreasing reflection of sunlight from the earth
0.5 watts per square meter in 20 years
Scientists recently published a study on Earth's reflection of sunlight. They came to the conclusion that in two decades our planet's reflectance has decreased by about 0.5 watts per square meter. This means that this amount of energy was absorbed by the earth - and contributed to the warming. One reason for this could be less cloud cover over the Pacific Ocean.
Seen from space, our planet appears (a bit) darker. However, we don't feel it ourselves. In fact, in many cities we can observe an opposite effect at night: general light pollution. It is about man-made light sources that illuminate the night sky.
