Road Trip 2020

Fires. Floods. Hurricanes. Disease. The world has always faced these challenges, but as the climate changes, some disasters are becoming more frequent and more destructive. And others, like shrinking sea ice in the warming Arctic, will have consequences we have yet to experience.

Innovators around the world are working on ideas, big and small, to help people -- and entire cities and countries -- cope with natural emergencies. For Road Trip 2020, CNET's team of reporters, photographers and videographers introduce you to the thinkers working on new technologies, new products and new services that can help prepare us to cope with a changing planet.

But what about you? What can you do to take control, protect yourself and embrace new thinking to become part of the solution rather than just a bystander? We're also offering pragmatic advice -- how-tos, FAQs, explainers, simple ideas -- designed to help you protect yourself and hack your way out of emergency situations.
