<p class="MsoNormal"><span style="font-family:"Times New Roman",serif;color:black;background:white">Geospace, the region of Earth’s atmosphere from the mesosphere to the exobase, is experiencing long-term change due to increasing carbon dioxide. These effects
have been predicted for several decades and are now becoming apparent in multiple data records. The cooling of Geospace is anticipated to result in a contraction of the atmosphere and result in a permanent reduction of density at fixed altitude. Variable solar
activity complicates the assessment of Geospace change. The ongoing change in Geospace has implications for the growing space economy, international space policy and law, and the space insurance industry. We welcome papers on all topics related to Geospace
change. In particular, we solicit papers related to numerical/computer modeling of the effects of long-term change, observation requirements, and new technologies for systematic investigation of Geospace change. We particularly welcome contributions from members
of the space industry to discuss their needs for knowledge of Geospace change.</span><span style="font-family:"Times New Roman",serif;color:black;mso-ligatures:none"><o:p></o:p></span></p>
