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.

Soot Now Outranks Methane As Global Warming Agent

What's the Latest Development?

A report published Tuesday in Journal of Geophysical Research confirms a 2008 claim that black carbon -- more commonly known as soot -- has taken over from methane as the biggest human-generated contributor to global warming after carbon dioxide. Emissions, which come from wood fires and diesel engines among other sources, have twice as much of an impact on climate change as previously thought. The findings emerged on the same day that two US governmental agencies announced that 2012's global average temperature was one of the warmest on record.

What's the Big Idea?

Although the US has been able to successfully reduce its soot emissions, China and parts of southeast Asia are still using a great deal of diesel, wood and coal power; Beijing's recent air pollution problems have been partially attributed to soot. In addition to improving air quality for humans and animals, cutting soot emissions would cause an immediate cooling effect, but it wouldn't be a long-term solution, says study co-lead author Tami Bond: "[T]o really solve the long-term climate problem, carbon dioxide emissions must also be reduced."
