It is just curiosity that forced me to ask this question. At some point in time, if we can't control global $\sf{CO_2}$ emissions, temperature will increase until a tipping point and it will be a complete catastrophe. However, if we could prepare ourselves through geo-engineering (e.g. carbon removal, blocking solar radiation), then we may return the temperature back to normal. I am not saying that we have to experiment with mother Earth, but if we may do weather-engineering experiments in controlled labs just like the Large Hadron Collider(LHC), we may some day be able to save the planet from catastrophe.
So, my question is, how bad does geo-engineering go as far as controlled experiments done in totally isolated labs?
In NWP models, it is mostly possible to control the evolution of $\sf{CO_2}$, solar radiation, moisture, temperature etc. Given the current computation power is better than in the past and will most likely be better in the future, once we have calibrated and validated those climate/weather models, can we use them to fight extremes of weather like floods, drought, hurricanes and all other wind storms?
The accuracy of current weather predictions is better for forecasts 5-10 days ahead. So, this may give enough time to do controlled simulations before and after our intervention. Based on that we may act on to, for example, increase precipitation (e.g. through controlled spraying of condensation nuclei) where there is drought, hit and disperse hurricanes or change their directions before they hit and damage cities etc. How wrong can one be to think like that?
