Detailed Analysis

The claim is partly supported, but the wording is stronger than the evidence. The sources support that Matthew Wielicki has publicly rejected mainstream climate urgency and has been described by outlets as a climate denier, and that he was appointed to help oversee the National Climate Assessment. However, the specific phrasing that he called climate-change effects "very minor" is not clearly verified in the provided results, and "the Trump administration has tapped" depends on the exact timing and context of the appointment.
