Global warming is Jamie Margolin's prime focus of activism. In her hometown of Seattle, she educated, protested, and campaigned for climate action at the age of 14. In 2017, she founded Zero Hour, a youth-led movement creating entry points, training, and resources for young activists against climate change.
She went on to lead a youth climate march in Washington DC and was part of the Global Climate Strikes. She also testified in front of Congress what it's like to be a youth with global warming posing a threat to her future.
