Thank you Amie. All very interesting. Good to read about Sylvia Earle’s career. Re Global heating, sadly, I think the unnamed South African scientist reported as saying “The world’s response to date is reprehensible—we live in an age of fools” has summed up the situation perfectly.
A helpful accounting!
