Said the Guardian newspaper in London in a recent headline about the grim news: “World’s carbon dioxide concentration teetering on the point of no return.”
Well, the Guardian may say it, but it would be nice if they would explain what it means. Every respirating creature on the planet is exhaling carbon dioxide (plants lay off during the day for photosynthesis, which produces oxygen, but at night breathe oxygen just like the rest of us). What is this point of no return? Return from where? These may be stupid questions, but stupid people deserve an explanation, too — and journalism is about asking stupid questions.
