What is Big Think?  

We are Big Idea Hunters…

We live in a time of information abundance, which far too many of us see as information overload. With the sum total of human knowledge, past and present, at our fingertips, we’re faced with a crisis of attention: which ideas should we engage with, and why? Big Think is an evolving roadmap to the best thinking on the planet — the ideas that can help you think flexibly and act decisively in a multivariate world.

A word about Big Ideas and Themes — The architecture of Big Think

Big ideas are lenses for envisioning the future. Every article and video on bigthink.com and on our learning platforms is based on an emerging “big idea” that is significant, widely relevant, and actionable. We’re sifting the noise for the questions and insights that have the power to change all of our lives, for decades to come. For example, reverse-engineering is a big idea in that the concept is increasingly useful across multiple disciplines, from education to nanotechnology.

Themes are the seven broad umbrellas under which we organize the hundreds of big ideas that populate Big Think. They include New World Order, Earth and Beyond, 21st Century Living, Going Mental, Extreme Biology, Power and Influence, and Inventing the Future.

Question: What changed your mind about global warming?

Richard Cizik: Well my mindset prior to going to Oxford 2002 Climate Change – that’s the name of the conference I was invited to – was look, there is a debate going on about the science of climate change. I don’t need to get into that. “Scientists dispute this,” I said to myself. I don’t have a dog in that fight. What happened? Well I was presented with the science by not only the world’s most credible scientist. The conclusion of course being that climate change is real. It will impact millions upon millions, and that the science was indisputable. Indisputable. And when confronted in this case by science . . . never mind the Bible. I … I thought I knew the bible. But when confronted with climate change, global warming in particular that threatens not just for example a river or lake, but the entire planet, virtually knocked me off my feet. Almost like a John the Baptist conversion in which he fell off a donkey on the road to Damascus. It literally knocked me off my feet and I said, “My God.” I said, “I’ve never seen this before,” the facts as presented. And then to have a fellow Christian, a scientist, one of the most premier scientists, the science advisor moreover to the IPCC, the Intergovernmental Panel on Climate Change to say to me, “Richard, if you are persuaded of the science . . .” This is what Sir John … said to me… “If you’re persuaded of the science, you can’t be quiet.” I knew in my heart he was right. And yet I also knew there would be a price to pay. And so I left Oxford in 2002 persuaded that yes, the science was indisputable; but … I would say, about the prospect of speaking out. Because even my closest friends opposed the idea of me doing that.
