On April 22, the world celebrates the 50th anniversary of the Earth Day. Have a look at the milestone moments of the evolution of climate action and climate science that marked this half a century, shown in our timeline.
Everything started on 22 April 1970, when environmental concerns led 20 million Americans to take to the streets to demand more action by policymakers. Since then, Earth Day continues to hold major international significance, and the climate change challenge has been recognized as the most pressing topic for the 50th anniversary, which is dedicated to “Climate Action”.
In the article “50 Years of Earth Day, Climate Action and Science“, published on the CMCC magazine Foresight, we summarize the main steps of the evolution of climate action and climate science over the last 50 years, and compare them to the trajectory of two data-based climate indicators – average global CO2 levels and average global temperature rises – in a timeline.
