Sarcasm I've also been following many of these issues for 50 years and have a pretty fair understanding of what's going on. In elementary school we got these science handout mini magazines that I was enamored with and a lot of our current climate issues were discussed long before they were fully understood but the people putting forth their ideas were mostly right. The transition period we've experienced over the last 30 years has pretty much proceeded on the schedule they proposed, not entirely but with the perspective that hindsight affords I'm not surprised by the results.
