The idea that it’s “too late” to reduce emissions fuels cynicism and despair, putting us on an even worse trajectory.
There are plenty of engineering obstacles, and those can be overcome. But you cannot change the laws of physics, and those matter too.
While ice itself is slick, slippery, and difficult to navigate across under most circumstances, skaters easily glide across the ice.
An introduction to "The Engine of Progress" from Jason Crawford, founder of the Roots of Progress Institute.
The case that a bipartisan movement structured around progress and reform may be reaching critical mass.
Bold megaprojects could turn dry depressions into thriving new hubs of life.
Solar power has the disadvantage that there's no Sun at night. Satellite startup Reflect Orbital wants to change that, but at what cost?
NASA's 1958 charter's top priority was, "the expansion of human knowledge of phenomena in the atmosphere and space." Is this how it ends?
Nuclear chemist Tim Gregory joins Big Think to make the case that nuclear energy can still transform the world for the better.
“Climate analog mapping” finds the place that is currently as warm as your city might be in 60 years.
In "After the Spike," Dean Spears and Michael Geruso show why policy, rather than high population density, has the most significant impact on the environment.
Here in 2025, many of us claim to come to our own conclusions by doing our own research. Here's why we're mostly deluding ourselves.

Tech expert Peter Leyden argues that we have a historic opportunity to harness AI and other transformative technologies in order to make a much better world over the next 25 years.
All scientific theories are limited in scope, power, and application, being mere approximations of reality. That's why consensus is vital.
We've wasted our time and resources ideologically policing and punishing each other for far too long. Here's a better route to prosperity.
