These comments do surprise me yes.

The amount of conflict in the remarks is because both parties are right. It's very wonderful for Jeff Bezos to donate $10B dollars. But also it's right about private jets, which generate much carbon pollution.

It's fair to say that everyone has to do their part against climate problems. I for one make personal sacrifices yes. Less meat, less consuming, trying for local purchases as often as possible so the cheese I eat is not from France, driving a lot less, and also I fly much less. This year only one trip home instead of two.

For us to lift out of poverty many more people, it's worrying about the carbon costs of this. But now we have to behave smarter and people for whom sacrifices are easiest should make them first.
