The full title name is Terrestrial radiative cooling: Using the cold universe as a renewable and sustainable energy source, contained in today's issue of the peer reviewed journal "Science."

I don't think this is an open access article, but there some scientists looking into materials that will shed more longwave energy than the shortwave energy received. If significant progress is made in this area of science, with enough surface area of special materials on rooftops, or other places near the surface, we would be one step closer to having a means of controlling the climate.

Here is one clip from the article:

It's a long way from practical yet

That has the potential to be a game changer, the >8C subambient cooling at noon is amazing.
In places that use a lot of air conditioning, knocking off the first 8C would be a large improvement.
 
Radiation also a big problem for our world

Not radiation, but the type and balance of it. The idea of net cooling is using materials were the spactral emmissivity and albedo create more radiant output outward than they receive from radiant absorption and conduction.

In the climate sciences, the term "radiation" doesn't mead radioactive. In the climate sciences, radiation is the emission or transmission of infrared, visible light, and ultraviolet.

From Wikipedia:
In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium.[1][2] This includes:​


The ISS for example uses light colored heat emitters. This way, they reflect most of the stronger wavelengths of the solar spectrum, and emit thermal IR. This gives the station heat radiators a net heat loss, to keep the station cool. These same heat emitters cannot be used on the surface, because the wavelengths need to be something that the atmosphere is transparent to. Finding such materials is the trick.
 
The impact of nuclear power plants on the environment in compliance with the construction and operation technology can and should be significantly less than that of other technological facilities: chemical enterprises. I interested in level of radiation in my place so bought geiger counter on https://ecotestgroup.com/
