I totally get and agree with the instinct to simplify by saying "It's like a greenhouse" or "a heat-trapping blanket" but, like, what's actually going on? It's not that complicated! More energy is coming in than is going out because of WIGGLES. And yes, I'm talking about this because it feels like maybe MAYBE the US will have a climate bill that will actually, measurably reduce emissions on a fairly tight time scale which is massive.
