Our Centennial year marks an important milestone for the American Geophysical Union. Since our founding in 1919, AGU has evolved in ways too numerous to count. Yet our mission remains the same: to promote discovery in Earth and space science for the benefit of humanity.

We’re celebrating our 100th anniversary because it provides an opportunity to further our efforts to activate mechanisms that connect members and others inside and outside the ESS community; amplify the voice of the ESS community and the contributions it makes to society; and inspire Earth and space scientists to help improve lives around the world.

Centennial is both about commemorating the past and looking to the future.

So, we ask you, our members, the broader science community, and anyone interested in the wondrous mechanisms of our planet and universe, to join us. Over the coming months, we plan to look back at the scientific breakthroughs that have propelled us through the last 100 years. Simultaneously, we will look towards the grand challenges, discoveries and solutions that we and future generations will share over the next 100 years.

It’s going to be an incredible journey.
