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.

What Deep Time Can Tell Us About Climate Change

The earth has certainly gone through a lot of hot times and cold times.  What I do is study deep time by looking at Co2 levels and relative temperatures and we are coming out of a cold time and moving into a hot time.  However, for this particular time in history, we should be moving back into a cold time.  

If we consider the entire ice ages of the last 2 ½ million years, we’ve been in a 10,000 year calm of warmth, and it’s time to go cold again. And yet, it doesn’t seem to be in our cards because of all the carbon dioxide we have put into the system.  In fact, we are now at levels that the world has not seen for the last 40 million years and we will soon be at carbon dioxide levels that existed 100 million years ago when we had a true hot house world.  

So, the game has been changed.
