Out of SpacePresent Our planet has been seen for a long time system in A sensitive balance. However, a new NASA project now shows a change: The earth darkens.
According to data that have been collected by the NASAS for over two decades Ceres (Clouds and the radiation energy system of the earth) project, the earth is now more absorbed Solar radiation Instead of reflecting on it.
The real surprise, however, is that this change is not uniform because the project is an inversion in the discovered Energy balance the planet.
Initially Ceres Data showed that the south won an additional 0.20 Watts per square meter (f/m²) every decade. However since 2020, This trend has vice versa.
Now the country is darkening more on the other. At the moment it is Northern hemisphere catches more energyWith an excess of 0.54 W/m² more than in the south every decade.
This figure is small, but a huge one Energy weight weight On A Planetary Scaling yourself year after year.
Defined puzzle: What is “albedo symmetry”?
This discovery breaks the assumption that that Earth Had a mysterious “Perfect symmetry“A puzzle that scientists have been confusing for decades.
Despite their big differences, the north and south and south differences hemisphere Reflected exactly the same amount sunlight. This is known as “albedo” symmetry“.
The balance Was a mystery. This is because the Northern hemispherewith much more Land massshould have differed from the south. The latter is dominated by darkness Ocean This absorbs more warmth.
Scientists theorized that other factors such as Clouds and industrial generation pollutioncreated a tender and maybe artificial balance.
However precise Satellite Data from the past two decades show that this balance breaks. Aside from that, The earth darkens More on the one hand: What does that mean?
Why did the shining “symmetry” and earth change More darkens in the north
Although it is hard to believe, specialists believe that one of the causes of this change is explained by you Environment Victory. Ironically the reduction of Air pollution This novelty could explain in industrialized countries.
Although it is harmful, the tiny particles are generated by pollution (known as Aerosols) are very reflective and helped to jump sunlight Back in space.
With the acceptance in pollution less in regions such as China, the United States and Europe sunlight is reflected. This causes that surface absorb energy.
This is made by Norman G. Loeb, the main underground Ceres Project at NASA: “It underlines the acceptance in Aerosols in the northern hemisphere due to the reduction of pollution in China, the United States and Europe ”.
In addition, the specialist adds a second factor: “The increase in the increase Melt from Snow And IceWhat was faster in the northern hemisphere than in the south ”.
As Snow And Ice (highly reflective surfaces) are replaced by the dark water of the oceanThe planet loses part of his reflective shield. This effect is much less pronounced in the south. That is because Antarctic also lose IceBut at a much slower speed to maintain a large part of it Albedo.
The northern hemisphere darkens: implications
So what changes this in the bright glowing balance from Earth imply? Despite good news without pollution out of Aerosols– It is still believed that this imbalance accelerates global warming in the northern hemisphere.
The excess of 0.54 W/m² of energy that the north absorbs over the south global warming are more pronounced and accelerated in the north.
This change has already observable effects, such as B. Changes in precipitation Pattern and atmospheric and oceanic Traffic.
It even causes a shift north of the Intertropical convergence zone. This is “a belt around
