"The e-mails come thick and fast every time NASA scientist Gavin Schmidt appears in the press.
Rude and crass e-mails. E-mails calling him a fraud, a cheat, a scumbag and much worse.
To Schmidt and other researchers purging their inboxes daily of such correspondence, the barrage is simply part of the job of being a climate scientist. But others see the messages as threats and intimidation – cyber-bullying meant to shut down debate and cow scientists into limiting their participation in the public discourse."
