What the Department of Energy does, and why Rick Perry is a bad choice to run it.

I think there is something sleazy about funding nuclear weapons through the Department of Energy. It looks like a way to disguise how much of US government spending is actually on weapons and war.

Most Americans no longer earn more than their parents did. The "land of opportunity" is no more.

CO₂ from fossil fuel combustion can be collected through a process that makes limestone, avoiding the need to quarry limestone.

Human activity emits 130 times as much CO₂ as volcanoes do.

The US will stop selling some missiles to Salafi Arabia because of its using them for war crimes in Yemen.

This decision does not come because the US has learned new information about that intervention, in which it has been closely involved all along. It is a political decision.

At least it's a change in the right direction, so I won't quibble.
