They actually did have this awessome idea to warm the planet up. It was in a rumour or news infocard somewhere.
Some guy had this 'great' idea to build a massive solar reflection array above the dark side of the planet* and light up a particular area of the planet so that they had more daylight hours.
...
It somehow turned out ot be a weapon of mass destruction which brought a bolt of searing, bright, burning death on the target area. People were quite angry.
* IIRC, for half of New Berlin's orbit around the star, one half of the planet is in shadow, and the other half of the orbit the other half is in shadow. If we say that NB has a solar year per orbit, then it's six months dark, six months light, alternating for each hemisphere.
Edit: I see you picked up on that. 1 year, 1 year, I apologise.
