We will wait until the very last minute to do anything significant, reacting rather than anticipating. Then, when the effects of climate change are completely undeniable, we will try work-arounds other than solving the underlying cause. My thought is that we will eventually try to put a thin reflective material into space (or manufacture it in space in 20-40 years) to create some sort of semi-permanent sun-shield that reflects 2-5% of the sunlight we receive. It would have to be massive in area, but think of your car's sun visor on a hot day. Putting particles into the atmosphere to do the same thing would also do the job but it could affect other things and cause more abnormal weather. I don't see our use of fossil fuels or consumption of livestock slowing down. People make exceptions for themselves because they are the center and most important part of their own experience. "You can't get a man to understand something when his job depends on him not understanding it" - Upton Sinclair. Also it's worth saying that Bill Gates should be able to do better than a tiny 1 billion (1/96th of his wealth) given the dire situation we are in. Actions taken earlier will have a larger impact toward mitigating climate change. 1 billion is like him tossing a penny at the problem. I'm sure Microsoft has contributed a large amount of CO2 to the atmosphere over time as well.
