After a tenure of eight years, a Tesla engineer has quit the company — and directed a seething missive toward his boss, Elon Musk. He also formally withdrew the US from the Paris climate accord, an international agreement to limit global warming to 2.7 degrees Fahrenheit, for the second time. Meanwhile, federal research grants are being canceled for merely containing the word “climate,” government websites are being scrubbed of any information on climate change, and NASA’s crucial climate satellite missions are set to be destroyed. “Climate change is real,” Musk tweeted in June 2017. “Leaving Paris is not good for America or the world.”That, incidentally, was the same year Balestrieri joined Tesla energy.
