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.

Plants Absorbing Less CO2

August 22, 2010, 7:15 AM
"Rising temperatures have helped blunt plants' ability to pull carbon from the atmosphere, according to a study published yesterday in Science." Is it a threshold in the warming cycle? Scientific American reports that: "The amount of carbon soaked up by Earth's plants and trees fell by roughly 1 percent, or 550 million metric tons, between 2000 and 2009. Researchers at the University of Montana say that global warming, large-scale droughts and an overall drying trend in the Southern Hemisphere contributed to the drop. Warmer temperatures did lengthen growing seasons in high northern regions, but that wasn't enough to counteract the effect of changes in Earth's water cycle."
