Free online data, including satellite, sensor, and climate models, empowers individuals to understand and address air pollution and climate change. These petabytes of resources offer immense value in devising solutions to critical environmental issues.

James Poetzscher, a 17-year-old high school student, exemplifies this. He has authored four research papers, mapped global air pollution decline for the European Environmental Bureau (published by BBC, Reuters), and created a global map inventory on his website greeenhousemaps.com. He also built an air quality data portal and writes for major media. James aims to inspire young people to take collective action on these century-defining issues.
