First tree on Mars:' Scientists measure greenhouse effect needed to terraform Red Planet

[Admin]

What is the amount of greenhouse warming required to heat up the cold climes of Mars enough so that trees can grow on the Red Planet?

Maybe the authors of this article should read this previous article: https://www.space.com/31044-mars-terraforming-nasa-maven-mission.html , which says the CO2 just isn't there in sufficient quantities to terraform Mars, because it was swept away by the solar wind billions of years ago. So, even if we somehow find more CO2 than currently expected and try to get it into the Martian atmosphere, would we be able to get it in faster than the Sun takes it out? And, if we could achieve that, how long would it last?

Mars has no magnetic field so the surface of the planet is not only continuously bombarded with deadly radiation, it cannot hold anything beyond an extremely thin atmosphere. If this problem could not be overcome then discussion of growing the first tree is putting the cart before the horse.

It might take an M field to produce and maintain an ionization layer for a contained atmosphere.

But it would take much more than an atmosphere to accommodate a tree. It needs certain inorganic and organic compounds, plus a biofilm in that density to convert, condition and transport the needed nutrients.

One needs a living world for a tree. I doubt many lifeforms can survive a non living world. Life is a large living flux. Discreet, but dependent.
