We?

A once well-known quote among us was, "Everyone talks about the weather, but no one does anything about it."
'Us' implies a 'we,' doesn't it? 'Everyone' refers to 'every one of us,' doesn't it?

When you say, "We now seem to be taking some responsibility for the weather as we begin to take responsibility for our climate." Who do you suppose the 'we' refers to? Who makes up a 'we?' How do individuals become a we?
