Humans are adept at modifying their enviroment and that includes building natural gas pipelines, electric grids, solar systems, windmills, coal fired plants and nuclear plants. It also includes tapping geothermal heat.

There are people that thrive living "off the grid" but most of us are interdependent and actually it is not going to unravel due to climate change... but rather societies tend to congregate when put under stress. Just watch how people help each other during national emergencies.

So, if your point is the quality of human life is dependent on the amount of energy we consume, that is true and has been true since man discovered fire. If you think climate change is going to cause society to unravel, there is zero evidence of that.

If governments decided that climate change was truly a threat and not a convienent political issue we could build enough nuclear power plants in countries that already have nuclear technology to provide all the "clean" energy needed for 70% or more of man's energy needs. These new nuclear plants have the advantage of 50 years of improved technology and no longer need to be located close to population or water sources and can store more than 400 years of spent nuclear rods in deep tunnels on site.
