On May 8, Lennart Bengtsson, a Swedish climate scientist and meteorologist, joined the advisory council of the Global Warming Policy Foundation, a group that questions the reliability of climate change and the costs of policies taken to address it. While Bengtsson maintains he'd always been a skeptic as any scientist ought to be, the foundation and climate-change skeptics proudly announced it as a defection from the scientific consensus.
Less than a week later, he says he's been forced to resign from the group. The abuse he's received from the climate-science community has made it impossible to carry on his academic work and made him fear for his own safety. A once-peaceful community, he says in his resignation letter, now reminds him of McCarthyism.
"I had not expect[ed] such an enormous world-wide pressure put at me from a community that I have been close to all my active life," he wrote in his resignation. "Colleagues are withdrawing their support, other colleagues are withdrawing from joint authorship."
