The Brighter Side of News
, research analyzing 24 years of data from NASA’s Clouds and the Earth’s Radiant Energy System (CERES) instrument reveals that the Earth absorbs and radiates energy in two main forms, namely incoming solar energy or absorbed solar radiation (ASR) and heat released back into space or outgoing longwave radiation (OLR).

When compared, the northern hemisphere is recorded to absorb more sunlight.In the study period, this region received an additional 0.34 watts per square meter every decade compared to the southern hemisphere.
Even though this number seems small, its impact is considered significant on the Earth’s energy balance.
The phenomenon of the darkening of the northern hemisphere is mainly influenced by two major factors.

Earth
, the melting of ice and snow makes surfaces that were previously bright turn darker, so that sunlight that should be reflected is instead absorbed.
Another factor is cleaner air due to reduced pollution and aerosol emissions in North America, Europe and parts of East Asia.This condition makes the sky clearer so that light scattering is reduced and more sunlight penetrates to the surface.
An imbalance in light exposure between north and south has the potential to disrupt atmospheric circulation patterns, ocean currents and global temperature distribution.
Scientists warn that these conditions could trigger significant changes in the climate system.The darker the Earth’s surface, the less light is reflected back, so warming occurs more quickly.
Although this shift has been clearly detected, the long-term impact on global climate still requires further research.
Continued satellite monitoring as well as more detailed climate models are considered critical to understanding the extent to which these changes will affect different regions.
The researchers emphasize that accurate predictions can only be achieved with long-term observations, given the complexity of the relationship between energy, the atmosphere and the ocean.
