Baking, I think you are probably right and I'm the one in a bubble. In most conversations I would have, at work, school gates and friends, anyone sharing news of upcoming holiday plans involving flying would preface their announcement with "Oh, I know it's really bad, you know envirinmentally and that, but guess what? We're off to the Maldives -yay!"
Laurie , I take your point about judging, and I always enjoy and respect your posts here, but isn't the whole point that we do not, just like you say, have individual carbon 'spends', so each carbon-liberty I take is actually a 'debit' from the global collective account, which is already overdrawn? And that as an individual stake holder I am not being 'judgmental' by objecting to the questionable and detrimental transactions of others? And again, what does it really matter if others think me meddling and judgemental if by challenging individuals (as well as companies and politicians) I contribute to bringing about a broader conversation about climate change? I think the time of personal sensitivity and individual choice as being beyond reproach is gone, and that we are going to need to expect to be held to account socially for the environmental choices we make. This is a big motivator for changing behaviour.
Just to say, I am not big on judging others in other areas of life, and have had my share of adverse circumstances to know that we don't always make optimum choices, but when it comes to the good of all sentient beings I reserve the right to hold people to slightly higher standards.
