GlacierHub Writers and Editors Share What Earth Day Means to Them

Earth Day is the anniversary of the birth of the modern environmental movement, which began in 1970. Fifty years later, “Earth Day is widely recognized as the largest secular observance in the world, marked by more than a billion people every year as a day of action to change human behavior and create global, national and local policy changes,” according to

Since the inaugural Earth Day, the concentration of carbon dioxide in the Earth’s atmosphere has increased from 324 parts per million in 1970, to more than 414 ppm today. Scientists expect 2020 to be the warmest year on record for the planet, and climate-caused natural disasters have placed the climate crisis front and center. Public demonstrations demanding climate action had seemed to be gaining traction over the last year, leaving activists hopeful that 2020 would be a year of positive development. Earth Day 2020 celebrations had planned to be a significant worldwide event—until coronavirus. Many of the shows will still go on, just online.

The GlacierHub staff decided to acknowledge the semicentennial with a personalized video tribute. In each clip you can meet the faces behind the bylines, hear what Earth Day means to each of them, and revisit their favorite stories they’ve researched.
