How do I get rid of DOME on a planet?

[Tough Guy]

What do I need to get and what research is needed?

Also, is it worth it to use the climate control facilities? What does the 1,2 or 3 % really mean? Will it improve happiness?

The dome is because the population on the planet can't breathe the atmosphere. Basically you get 1/5 space for population, cargo, and facilities. Two ways to get rid of them:

1) research the Planetary Engineering tech until you get atmosphere converters, then use them.

2) obtain (capture, trade, etc) for alien population which breathes that atmosphere and replace the population with the right breathing race.

#2 is usually faster, but you have to take some extra measures to keep alien population happy.

See the Newbie FAQ for the answers to these and other questions.

If that planet has a atmoshphere that should be breatheable for you, might I suggest this link.
