It's not disingenuous or lazy. Many people of the past died during heatwaves. The reason that doesn't happen so much these days is that we have cheap, plentiful, reliable power from fossil fuels. Renewables aren't up to it, at least not reliably. Is it not a tad psycho to advocate the abolition of fossil fuels that could easily put many people back in the situation of dying due to heat or cold... while sitting in the comfort provided by fossil fuel powered AC? Please, at least write such messages in the dark, sweating.
