Why the Arrogance?
The climate on earth is always changing. It is created by the interactions of the entire biosphere, plate tectonics, ocean currents, solar radiation, maybe even cosmic radiation and who knows what else.
And you say we understand this?
The climate on earth has always been in flux, it was long before humanity arrived and it will stay in flux until it is swallowed by the sun. Well okay, once the expanding sphere of gas blows away the atmosphere climate change will stop.
In other words wouldn't our energy be better spent not trying to control the climate but developing technologies to allow us to better deal with disaster and harsh conditions? And bonus, these technologies might be useful on other planets.
Should we invest in renewable energy and better and cheaper forms of energy? Hell yeah. Pollution in all it's forms should be limited as best we can. But we can't control the planet, it is far bigger than we are, and far older.
In other words stop talking shit and do something useful.
Yeah I really just felt like ranting.
