But what is the seriousness of these issues? We're inundated with articles pointing out small unimportant changes and unquantified waffle about serious future changes. But never any actual predictions of global disaster. What's the expected cost in money or lives? Nobody has a clue beyond "catastrophe", whatever that means. I saw one estimate for the economic cost to Canada but it was so low that the citizens could actually just pay it as an additional tax and carry on with life hardly affected at all. Alarmists were actually critical of that data being published because they were afraid it might support people's belief that it's not very serious. Maybe because it's not? So if you're going to say global warming is serious, can you also quantify what you mean? Otherwise you're only conveying your personal subjective feeling.
