Consider the possible scenarios and determine which of them are true for positive feedbacks or negative feedbacks. a. increased plant photosynthesis resulting from a temperature rise can remove carbon dioxide from the atmosphere which can potentially lead to positive feedback. b. increased evaporation resulting from a temperature rise can produce more clouds which can potentially lead to a negative feedback. c. increased plant photosynthesis resulting from a temperature rise can remove carbon dioxide from the atmosphere which can potentially lead to a negative feedback. d. increased evaporation resulting from a temperature rise can produce more clouds which can potentially lead to a positive feedback. e. if ice cover melts due to a temperature rise the result will be decreased albedo or reflectivity which can potentially lead to a negative feedback. f. if ice cover melts due to a temperature rise the result will be decreased albedo or reflectivity which can potentially lead to a positive
