No they don't. Look I am trying really hard not to explicitly tell you what I know to be true so lets try a softer approach. Where did you find this value that you claim to be valid?

And for those who still can't figure out what I am thinking. There will NEVER be a response with a link because no such thing exists. When we talk about abrupt changes ... the last one of record resulted in quick-frozen Mammoths in Siberia. And that was quite a bit longer ago than 300-400 years.

You keep putting 'em up dehammer and I'll just keep knocking them down. Don't you ever learn?
