Open Source Terraforming - Jamais Cascio kertoo miksi Maapallo täytyy terraformata. Ei riitä, että palautamme Maapallon ilmaston sellaiseksi kuin se oli, siitä täytyy tehdä parempi kuin se on koskaan ollut.
But none of these solutions — ultra-efficient buildings and vehicles, top-to-bottom urban redesigns, local foods, renewable energy systems, and the like — will do anything to reduce the anthropogenic greenhouse gases that have already been emitted. The best result we get is stabilizing at an already high greenhouse gas level. And because of ocean thermal inertia and other big, slow climate effects, the Earth will continue to warm for a couple of decades after we stop all greenhouse gas emissions. -- The Virgin Earth Challenge isn’t simply looking for better ways to reduce or eliminate new greenhouse gas emissions, it’s looking for ways to remove existing CO2 and other greenhouse gases from the atmosphere — that’s what “net removal” means. It’s looking for ways to make an active, substantial change to the Earth’s atmosphere. Richard Branson is looking to underwrite re-terraforming, and given that the consensus new mainstream environmentalist position is to be solidly anti-geoengineering, the lack of reaction to what is essentially the “Terraforming Challenge” is a bit surprising.
