Post Letture per la domenica

Letture per la domenica Una cosa che rende la vita un po' più interessante e amara al tempo stesso è parlare con gli scienziati e usare un po' di metodo scientifico per fare calcoli, proiezioni eccetera. Ma tanto il riscaldamento globale non esiste, no? Money quote: "A climate scientist half-jokingly once told me that if billionaires really wanted to save the planet, they would buy everyone a heat pump, the ingenious appliance that extracts heat from even frigid winter air to warm a home, then reverses in the summer to act like an air conditioner. A heat pump is far more efficient than even the most efficient of gas furnaces. And because heat pumps just need electricity to run, you can plug them into a grid powered by renewable energy and avoid burning fossil fuels altogether" https://grist.org/energy/heat-pumps-expensive-bought/
