Not everyone has the luxury of reading about climate change.

Marinel Ubaldo had just turned 16 when Typhoon Haiyan struck the Philippines in 2013, taking the lives of more than 6,000 people and injuring at least 28,000. Ubaldo's family survived but their village was swept away, forcing them to go days without food, water or shelter.

Now 22, Ubaldo is a climate activist who lobbies with politicians and leaders on issues that include banning single-use plastics, reducing carbon emissions and investing in renewable energy sources. In October she traveled to Japan to attend a two-day climate leadership training event in Yokohama, organized by former U.S. Vice President Al Gore, and to host speaking events at universities around the country.
