    We've heard news of "peak oil" and "the end of the oil age" for years now, but we keep coming up with ways to find and pump more of it to the surface. Rising CO2 levels and the changing climate that results from burning fossil fuels mean that we should probably stop using oil sooner rather than later, though
    Let's take a look at history and see how we've used different fuels, so that we might figure out when and how to make oil a thing of the past

    Ocean currents are our planet’s circulatory system, and they keep everything from ecosystems to the climate healthy. But we’re changing Earth in ways that threaten to disrupt and even break critical ocean currents like the planet-wide Great Ocean Conveyor. This could have devastating effects on our future. In this video, we explain how ocean currents work, how climate change is threatening to disrupt them, and what we can do to stop that from happening.

  • Is Space a Thing?

    Since the days of Ancient Greece, philosophers and scientists have been wondering: What is space? Is the absence of things… a thing? These questions continued to fascinate physicists in the modern era, leading Isaac Newton, Ernst Mach, and Albert Einstein to wonder about the true nature of the fabric of the cosmos. The search for an answer led them to some of the greatest theories in physics. This week, we ask if space and time are really real, and how they come together to make “spacetime”!

    Wind is everywhere. The air is constantly moving, sometimes gently, sometimes violently. Why? Pressure, temperature and rotation come together to make wind in some *cool* and unexpected ways.

    Special thanks to Raymond Schillinger for great camera work!
    I was in Arizona recently for Phoenix Comic-Con, and had the amazing pleasure of seeing one of Earth's greatest natural wonders… the Grand Canyon. More than a mile deep, and several miles across, it just defies belief. But I couldn't help but think, the Colorado River down at the bottom isn't that big. How did it cut a canyon so massive? How old is the Grand Canyon?
    Here's its story

    What’s the largest river on Earth? If you said “the Amazon”… you’re only half right. Scientists have discovered an even bigger river in South America, and it’s in the sky above the Amazon rainforest. Turns out, this sky river is the reason there’s a rainforest at all…
