[Shindell starts spouting alarmism around the 1-min mark] Al Gore's "24 Hours of Reality" Greenland panel discussion: Dr. Drew Shindell (NASA), Nathan Currier, Naomi Levine (Harvard) and others discuss potential impacts of changes in Greenland, during Hour 22 of 24 Hours of Reality, 2011.

...We could incorporate perhaps a few number of the "usual suspects" (say just Phil and Ray), and I would want to include Drew Shindell and/or Gavin Schmidt, along w/ Caspar Ammann and/or Simon Tett--Tom Crowley would be logical to include too, unless you say any sort of conflict here. In my experience, Von Storch can be difficult, to say the least, and I would just as soon avoid including him (having tried my best to jointly organize workshops and special sessions with him in the past, and with limited success at best). Will await further word from you, mike

[Shindell] It’s fundamentally scary to think about something dangerous [CO2] that lasts thousands of years in the atmosphere. Think of nuclear waste – would it really be so frightening if it was as dangerous but only lasted a few weeks?

[2007] Drew Shindell, a climate scientist with NASA's Goddard Institute for Space Studies, said that climate scientists frequently have been dissuaded from talking to the media about their research, though NASA's restrictions have been eased.

Prior to the change, interview requests of climate scientists frequently were "routed through the White House" and then turned away or delayed, said Shindell. He described how a news release on his study forecasting a significant warming in Antarctica was "repeatedly delayed, altered and watered down" at the insistence of the White House.

"In the past 30 or 40 years you can see the global warming distinctly," Shindell said. "The planetary temperature is going steadily and sharply up."
