The world is fading! This has been shown to be related to the effects of climate change.

Warm seawater is associated with climate change or climate change as the brightness of the world decreases. That is a new study. Scientists measure the reflection of light from the earth (Earthshine)

Scientists have been measuring the Earth’s light for decades as the Earth’s reflection on the Moon’s surface decreases. This corresponds to the size of the moons, which have shown a significant decrease in Earth’s reflection over the past two decades.

In a study published in the AGU Journal of Geophysical Research Letters, current global reflection is about half a watt per square meter lower than it was 20 years ago, about 0.5% lower. .

Philip GoodeThe researcher at the New Jersey Institute of Technology, who led the research team in this study, said: Based on data collected from the Big Bear Solar Observatory in Southern California from 1998 to 2017.

The two factors that transmit sunlight to the earth: the reflection of the sun’s light from the world, and in this study the researchers found that this change in the Earth’s albedo did not correspond to the timing of the sun’s change in brightness.

It means that the change in the reflection of the earth is due to some reason of the earth itself. Especially the eastern part of the Pacific Ocean. The brightness and reflectivity of the cloud layers have decreased in recent years. From NASA’s satellite measurements of clouds and the Earth’s Radiant Energy System (CERES) project.

It has been documented to study a region known as the Pacific Decadal Oscillation, which is thought to be related to climate change.

What does the amount of solar energy absorbed by the Earth’s climate system in the dim world or otherwise show? Significantly, when this increased energy is absorbed, it affects the atmosphere and the world’s oceans. Global warming is likely to have a greater impact on climate change as it absorbs more energy from the sun over the past two decades.

Edward Schwitterman An astronomer at the University of California, Riverside, was not involved in the study. He added, “This is actually very worrying,” because scientists generally expect it to be more cloudy in a warmer world. This will help to reflect the light of the world. This will help to balance and reduce global warming to some extent. But this study shows the results of the opposite truth.

The average annual Earthshine albedo 1998–2017 is expressed in watts per square meter (W / m2).  Annual CERES albedo 2001–2019, shown in blue.  The blue dotted line represents the most appropriate line for CERES (2001-2019) data.  The average error bar of CERES measurements is 0.2 W / m2.  Image by Good et al.
