CO2:
More specifically, this is the problem:
This is the amount of CO2 in the lower atmosphere (in ppm).
The remainder of my life's work will be addressing this problem. Currently I'm working on a system for Decentralizing carbon emissions ownership away from governments so the problem can be owned and operated on by individuals (via private carbon offset ownership - i.e., a free-market system). Monetizing carbon emissions removes the imperative of government control, which obviously (and rightfully so) has many people nervous about attacking the problem from this avenue (UN, Cap and Trade, Carbon taxes, etc). It is also self-correcting: if carbon emissions have no impact, which is becoming increasingly unlikely but let's just say for this instance, then the free-market ecosystem value drops to zero. On the flip side, climate deniers become irrelevant overnight.
The other thing I am working on with a company is grid-level energy storage. Sorry, lithium ion batteries ain't going to cut it (I know a lot about this so don't bother arguing). We are developing a thermo-electrochemical storage paradigm, which is the only way you will get 2,000TW of storage deployed in a meaningful timeframe.
The good news I am solving this problem for you, so you don't have to do anything but keep smoking Oz's mary jane. I'll keep it short today, but I have a lot more to say and will happily keep Steemit apprised. Feel free to follow me to keep updated...
Have a nice day :)
