About AGU Blogosphere

Welcome to our network of blogs about Earth and space sciences, hosted by the American Geophysical Union, the world’s largest organization of Earth and space scientists. Most blogs in this network are written by independent scientist-writers; A few — GeoSpace, The Plainspoken Scientist and Meetings — are written by AGU staff (with occasional help from collaborators/guest bloggers).

Bloggers contribute to this network for many reasons, but we all share the desire to write, to disseminate accurate information, and to enjoy discussing exciting science. With our postings, we aim to reach our fellow scientists and the broader public, without regard for national boundaries, and to stimulate lively, open discussion by means of our blogs’ comment fields.

Why does AGU host this blogger community? One reason is to provide a go-to location on the Web for timely, interactive, and regularly-occurring exchanges of knowledge and ideas regarding the Earth and space sciences that AGU represents. By supporting this blogging community, AGU also fosters greater public awareness and understanding of Earth and space sciences, and facilitates more effective use of scientific knowledge to address society’s needs.

Some details about our blogs:

  • The independent bloggers have complete editorial freedom, both for the topics they cover and the way they moderate their comment threads.
  • None of our blogs run external ads. The independent blogs are100% ad-free. However, AGU reserves the right to display AGU-related ads on the network’s homepage and on AGU’s in-house (staff or guest written) blogs’ pages.
  • The opinions expressed in the independent blogs, as well as in invited-guest posts in the in-house blogs, are those of the authors and do not necessarily represent the views of the American Geophysical Union, its leadership, its staff, or its members.
