The Earth is darkening due to climate change

Madrid Spain.

The sea water is warming The brightness of the earth has diminishedA study suggests that as the bright clouds reflect sunlight back into space, more energy is trapped in our planet’s climate system. AGU Geophysical Research Letters.

The team found it Land It now emits less than half a watt of light per square meter than it did 20 years ago.

This equates to a 0.5% decrease in reflection LandIt reflects about 30% of sunlight, and the bulk of that fall has occurred in landscape data over the past three years.

Used by researchers Measurements of ground light over decades Earth-reflected light- and satellite measurements that illuminate the lunar surface.

Data is down “Notable“Over the past two decades, the planet’s albedo (reflection of the Earth’s sunlight), New Jersey Institute of Technology (USA), which led to the trial.

“The fall of the albedo, when analyzing the data for the last three years, surprised us the most, almost 17 years after the flat albedo,” he explained. Philip Goode, The primary author of the study, which includes participation Institute of Astrophysics Of the Spanish islands of the Canary Islands.

The Sun light Reaching the Web Land It is affected by two factors: the brightness of the sun and the reflection of the planet.

The changes seen in the albedo were not relevant Periodic changes in the brightness of the sun, I.e. Variations in the Earth’s reflection They are caused by what is on our planet.

In recent years, the study indicates that there has been a reduction Bright low clouds And reflected in the eastern Pacific Ocean, based on satellite measurements made for NASA’s Ceres project.

Same area from the west coast North and South America, An increase in ocean surface temperature has been recorded as a result of climate change known as the Pacific Decade of Fluctuation. Global climate change.

That The earth is going dark There is an additional amount of solar energy in the atmosphere and the oceans, which contribute to global warming.

Planetary scientist University of California Edward Sweeterman I consider it “This is very worrying“It simply came to our notice then Land The heat will lead to more clouds and more albedo.

This increase in albedo will help balance moderate warming and climate change. “But this proves otherwiseSweaterman, he commented on the unrelated study.
