Respect for science is one of TMM's Basic Beliefs. Moderates, and all other humans, owe the climate-science pioneers described in this Guest Blog a debt of gratitude - along with citizen-scientists, activists and educators like George S. Turner (author of the blog), who continue studying climate change and informing all of us about it. Without them, our collective knowledge of climate change would have evolved much later – meaning it would have taken us even longer to understand (and eventually, reach consensus) that it is real, accelerating – and dangerous.
