Global Dimming: Fact or Fiction?

[Pythagorean]

Global Dimming!

a larvae alarm fad or serious business?

(from a fellow physics major:)
heresy: "When the planes stopped flying after 9/11, the sky was brighter"
heresy: "the sun is giving off less light over time"

Has this been the mention of any credible scientific publications?

Global dimming is a well-established phenomenon that has been studied and documented by scientists for several decades. It refers to the decrease in the amount of sunlight reaching the Earth's surface due to the increased presence of aerosols (such as pollutants) in the atmosphere. These aerosols can reflect and absorb sunlight, leading to a reduction in the amount of solar radiation reaching the Earth's surface.

This is not a fad or a myth, but a serious issue that has significant impacts on our climate and environment. The decrease in sunlight can affect plant growth, weather patterns, and even the Earth's temperature. There have been numerous studies published in reputable scientific journals that have investigated and confirmed the existence of global dimming.

The idea that the sun is giving off less light over time is not supported by scientific evidence. The sun's output of energy is relatively stable, and any changes in the amount of sunlight reaching the Earth's surface are due to external factors such as aerosols and clouds.

As scientists, it is important to rely on credible, peer-reviewed publications and data to understand and address issues like global dimming. While there may be some conflicting information or opinions, it is crucial to base our understanding on scientific evidence rather than personal beliefs or anecdotes.
