  3. Dr. Nina Byte · Tech & Science CorrespondentNinety-six percent are critically endangered, its highest risk category.

  4. Brock Thunderson · Chief MeteorologistNinety-six percent. I felt that in my knees.

  5. Hank Ledger · Lead AnchorThey looked at a hundred and twenty-seven of them. Nobody gets to say they missed a spot.

  6. Dr. Nina Byte · Tech & Science CorrespondentAnd without the climate projections, only twenty-four percent would be rated critically endangered.
