I might even go so far as plant a few policies in their heads. "We are in a climate emergency, and we should address it immediately with policies such as carbon tax-and-dividend, ending subsidies for harmful industries such as fossil fuels and industrial agriculture, investing in both established and promising renewable energy sources such as solar and wind and tidal and geothermal, reducing our dependence on cars with more electrified public transport and denser urban design, and encouraging better urban land use patterns with land value taxes." One sentence = one thought, right?

Knowing humans, if we didn't use this magical power to guide them to good solutions, a good number of us would conclude, "That's it, we need to nuke China and India to save the Earth!"
