There is no single answer to that, the atmosphere is too complex (in a mathematical sense) a system, as is our behaviour.
I know that, although I hold no degree and I´m just an electrician and pilot.
If I look at the current discussion and climate of discussion, then on could think there is ONE solution. The cohorts that are at the forefront of the discussion right now (at least here in Germany) are commonly not the people I would give the task of planning a childrens birthday party (at least if I like said kid). An 16. old autistic girl seems to be the new Einstein right now and anyone daring to just try to ask a few questions about this is shouted down.
