That's divesting from fossil fuels.
Indeed. He should have argued - we are directly reducing oil demand immediately! Far more immediate and calculable on oil consumption, than the vague gesture of selling a western oil-company stock at some point in the future!
He should have cut off the heat and lights and power from the dorms.

Let’s get real. Turn the thermostat down far enough to not allow water pipes to freeze. If the water pipes froze it would be far more costly to repair than to save on fossil fuel usage. You can still cut power to individual rooms and lock up the thermostats so they cannot be touched. There are other ways to prove the point without going to the extreme and getting the same results. Temperatures in the dorm at 55 degrees farenheit, most thermostats do not go below this setting, is still an uncomfortable temperature for most people and would not make the pipes freeze.
