Climber Alex Honnold is best known as the star of Free Solo, an Oscar-winning documentary that followed his rope-free ascent of the 3,000-foot (1,000-meter) face of Yosemite’s El Capitan. But he has also established the Honnold Foundation to bring solar power to those who most need it. This week on Zero, Bloomberg’s Akshat Rathi asks Honnold how he gets big things done and why helping communities get clean energy has become his other passion in life.

On the morning of August 26, a glacial collapse in the Himalayas triggered a flash flood that sent ice, mud, rocks and fast-moving water through a valley in Nepal, wiping out entire communities. This week on Zero, Akshat Rathi is joined by Lou Del Bello, who has been reporting on the disaster for Bloomberg News from New Delhi. They discuss what can be done to keep mountain communities safe, and why events like this are likely to become more frequent in a warming world.

Extreme weather events this year are starting to hurt food production in serious ways, which is likely to push up everyone’s food prices. That’s before the weather-wrecking super El Niño has really kicked in. So how do we build a food system that is more resilient, more secure and has lower emissions? Paul Behrens, British Academy Global Professor at the Oxford Martin School, joins Akshat Rathi on Zero to discuss.
