Earth Is Dimming
The world is losing its luster. Very fast. And that is becoming more and more of a curse. The ‘fever’ of the world is increasing. It is getting warmer. Due to the rapid increase in greenhouse gas emissions due to climate change.
A recent study gave this news. The research paper was published in the international scientific research journal Geophysical Research Letters.
According to the study, in the 20 years from 1996 to 2917, the brightness of the earth per square meter has decreased by half a watt compared to previous years. As a percentage, the brightness of the earth has decreased by 0.5 percent compared to previous years. This means it’s about to be the most delusional time of the year, as well.
Researchers have also found out why this is happening. They have seen that the temperature of the world’s oceans has risen more than ever before in these 20 years. As a result, the clouds above those oceans have become darker than before. The Earth is reflecting less sunlight into space than ever before because of the loss of brightness of the clouds. So sunlight has increased the temperature of the earth even more.
To understand how much sunlight the Earth is reflecting, researchers have examined the extent to which the Earth is reflecting its satellite Chad.
About 30 percent of the sun’s reflection is reflected back to space by the earth. According to the research paper, this amount decreased by 0.5 percent between 1996 and 2017. Photo courtesy of NASA.
Typically, 30 percent of the sun’s reflection is reflected back to space by the earth. According to the research paper, this amount decreased by 0.5 percent between 1996 and 2017. And it decreased mainly in 2015, 2016, and 2017.
Philip Goode, a theoretical physicist, and professor at the New Jersey Institute of Technology, the lead researcher, said: For so long, scientists have speculated that the Earth may be reflecting more sunlight into space for warming. But the results of our research say the opposite. “
The researchers analyzed the satellite imagery and found that the clouds at the very bottom of the eastern Pacific Ocean had lost much of their luminosity. As a result, the reflection of sunlight from that cloud has also decreased.
This region has become the main reason for the decline of the brightness of the world. Ocean temperatures have also risen sharply in areas above the Pacific Ocean where bright cloud levels have become thinner than before. That is because of climate change.
Not only clouds, but also water, ice, forests, and deserts all reflect sunlight into space. In some cases it is less, in others it is more. Researchers have found that the pollution caused by civilization is also behind the decline in the brightness of the earth.
Why is the earth bright?
The Moon and Earth both get their brightness by reflecting sunlight, and although the Moon looks greyish-white in the sky, it’s actually much more of a charcoal color. It only appears as white-colored as it does because of how much sunlight there is to reflect.
Why Earth is dimming?
It is thought that global dimming is probably due to the increased presence of aerosol particles in Earth’s atmosphere, caused by pollution, dust, or volcanic eruptions.
How cold is space?
-455 degrees Fahrenheit (2.7 kelvin).
What is the real temperature of the Sun?
The temperature in the photosphere is about 10,000 degrees F (5,500 degrees C). It is here that the sun’s radiation is detected as visible light. Sunspots on the photosphere are cooler and darker than the surrounding area. At the center of big sunspots, the temperature can be as low as 7,300 degrees F (4,000 degrees C).
How hot is the Sun’s corona?
The outermost atmospheric layer is the corona, which gets really hot, almost 2,000,000 degrees F. This is where the solar wind begins. These layers can only be seen during total solar eclipses. Here is where we see towering masses of luminous gas, called filaments or prominences, on the solar limb against the dark sky.
