Nothing to add. I introduce my next expert witness. Dr. Summerhayes takes us on a tour of climate science history and explains how scientists figured out, what they figured out, and why it matters.
Colin Summerhayes: Earth's Climate Evolution - A Geological Perspective - Earth's Climate Evolution rocks and ice as tape recorders of climate change.
You will hear this phrase used, “The climate is always changing,” - geologists particularly in the all oil industry I find are very fond of trotting out this statement. The climates always changing as if that means that we don't have to worry about the climate changes that are taking place now, or may take place tomorrow. ‘Ah, because the climate is always changing.’
To me that is what I call a mindless mantra it's a mindless measure unless you start thinking and you engage your brains and you start wondering yeah but what made the climate change, how it did, when it did. So that's what we have to do. We have to figure out going back in the geological record what made the climate change the way it did when it did. That’s what I’m going to talk about. (June 3, 2015)
