Doctors have lost control of field of medicine.Mr. Seehafer proposed a plan to centralize A.I. oversight at the health department or in the F.D.A. commissioner’s office, raising concerns that decisions would be more influenced by the tech sector than by medical considerations, according to people familiar with the plan who were not authorized to discuss it publicly.
The plan met with resistance from Dr. Michelle Tarver, the top medical devices official overseeing A.I. software, favoring leadership from expert scientists with a focus on patient safety.
Dr. Makary, who had been outspoken about the influence of Silicon Valley investors, then got word that health department officials wanted him to fire Dr. Tarver, according to people with knowledge of the matter. He refused.
“Nighttime temperatures have soared in the past 120 years,” Christy said.
“That is due to human development around the weather stations because nighttime temperatures are far more sensitive to urbanization—parking lots, buildings, removal of forests, and so on—than daytime temperatures.”
Over the past century, many locations where temperature readings were taken have been touched by urbanization and suburban sprawl, with the construction of asphalt and concrete structures in formerly rural areas, he said. These structures absorb heat during the day and release it at night.
“You can’t pin it on greenhouse gases alone because the urban effect is so obvious in these stations,” he said. “It doesn’t take much to make an urban heat island—you can just build a parking lot next to a rural station, and you’ve got an urban heat island started.”
