Starting in January 2026, publicly listed Brazilian companies will be required to disclose their greenhouse gas emissions. This follows similar actions taken around the world—from Australia to New Zealand and the European Union. What will we learn from these disclosures?...

To compete with China’s dominance in battery technology, the U.S. needs more than just ambition—it needs new chemistry. This episode traces the rise and fall of an American sodium battery startup and the quiet race to build a cheaper, safer,...

We should celebrate cleaner air, but we also have to reckon with an unintended consequence. It turns out that by reflecting sunlight back into space, tiny sulfur particles protected Earth from about a third of the warming caused by human...

 In the 1990s, millions of vultures quietly vanished from India—and the consequences were deadly. This is the story of how a cheap painkiller set off a chain reaction involving rabid dogs, polluted water, and tens of thousands of human...

When disaster strikes and funding fails, some experts and leaders are considering a Plan B: deliberately cooling the planet by reflecting sunlight back into space. This episode traces the science, the politics, and the ethics of geoengineering—from volcanic eruptions to...

Air conditioning isn’t the luxury some consider it to be—it’s essential to life in a warming world. The real problem is the fossil fuels that power it. This episode of Shocked explores what it means to use energy well, from AC to...

Are you tired of the same climate and energy stories? A warmer world is here. We’re living with it. Now what? Will countries ever stop burning fossil fuels? Should we use less energy? Can we adapt to a warmer world?...

Video As the world’s energy needs diversify, all forms of energy will require storage. Power grids, in particular, will need better batteries to store renewable energy. University of Chicago electrochemist Chibueze Amanchukwu is working to create a more sustainable future....

Between 2010 and 2020, the cost of electric vehicle (EV) batteries dropped by nearly 90 percent, reducing a major obstacle to widespread EV adoption. Industry experts attribute much of this decline to learning-by-doing, where production experience leads to lower costs...

By: David Keith and Anthony Harding (Georgia Tech) Climate change has risks—and those risks are only increasing. Many of these might be reduced by solar geoengineering. Solar geoengineering also has risks, and it requires rigorous, transparent research before it is...
