Thomas L. Delworth, an NOAA scientist who works in the Climate Dynamics and Prediction Group, will later say that by this date, a quarter of his prospective interviews with journalists have fallen through because of delays in the agency’s approval process. He also says that one third of the reporters he usually deals with no longer request interviews with him on account of the delays. He estimates that a typical request takes 24 hours to process while interviews that are potentially more controversial take longer, sometimes as long as five or six days.
