Perhaps you should try some spelling variations:
"climate scientific" » "climate scientists", "curate scientific", "late scientific"
"primate scientific" » "private scientific", "primary scientific", "promote scientific"
"climate scientist" » "climate scientists", "climate sciences", "climber scientist"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("climate scientist") OR ((("climate scientific") OR ("primate scientific")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"climate scientist\") or (((\"climate scientific\") OR (\"primate scientific\"))))".
• Removing quotes may allow a broader search: (( climate scientist ) or ((( climate scientific ) OR ( primate scientific )))).
• Adding a wildcard symbol may retrieve word variants: (("climate scientist") or ((("climate scientific") OR ("primate scientific"))))*.
