In all fairness, I would reject any opinions about biology and "conservationism" from a climate scientist or a Sea level researcher with decades of experience and world status.
Just saying.
"Experts" at anything deserve no respect when they attempt authoritatively to comment about any subject beyond their reservation.
I agree with you... “Scientist Peter Raven” is a botanist not a “climate scientist”, but in most cases “climate scientist” is a misnomer these days. Leftist anti-capitalist climate activist would be more accurate in most cases.
