The Earth has been “shining” less in recent years.

For a few years, the Earth has been “losing its shine”.

In other words, our planet is reflecting —or returning— less light from the Sun into space, according to a new study published in the journal Geophysical Research Letters, from the American Geophysical Union (AGU), in September.

The authors of the research, from the United States and Spain, reached this conclusion after analyzing data from thethe amount of light that the Earth reflects on the Moon, assembled over the last 20 years by satellites and by the Big Bear Solar Observatory in California.

Scientists still hope to pinpoint the causes of the reduction in Earth’s brightness, but they already have some hypotheses.
