This stands in stark contrast to theincreasing alarm over the climate emergency, resulting from an increasing greenhouse effect.
Both these forms of radiation have a critical impact on the habitability of a rocket planet.
Clearly controlling this radiation is a pressing issue on Earth.
But it also presents a challenge for those who dream of colonizing Mars.
This is shorter and more energetic than visible light.
By contrast, the wavelength of a typical 4G phone web connection is a few tens of centimeters.

It can also damage plants andharm crop production.
Without it, life on Earth would be in a lot of trouble.
Ozone is a naturally occurring molecule consisting of three oxygen atoms.
Natural factors can act as catalysts for this such asvolcanic activityand theEarths radiation belts.
The first observations that the ozone balance was in trouble were made in the 1980s.
IR radiation has a subtly different effect on Earth and other planets.
All objects emit a range of lightdepending on their temperature.
This is why people show up clearly in an infrared camera.
Sunlight, primarily at visible wavelengths, passes through the atmosphere and warms the Earths surface.
To maintainthermal equilibrium, the Earth then emits light back into space, but it does so in IR.
What complicates the climate issue is that water vapor and ozone itself are all greenhouse gases too.
This is one of the many factors that make climate modeling a verycomplex topic.
The greenhouse effect itself is usually described as a bad thing, but it is actually essential to life.

So what could we do to make the climate more similar to Earths?
Previous ideas have included installing agiant magnet in space near Marsto protect the atmosphere and firingnuclear weaponsat the surface.
