CAWSES-II in Japan

TG2. How will geospace respond to an altered climate?




Climate And Weather of the Sun-Earth System -II (CAWSES-II)

Radiative, chemical, and dynamical forcing from below contributes to disturbances of the upper atmosphere. In response to rising greenhouse gas concentrations, cooling in the middle atmosphere will alter the complex physical and chemical processes of this region. Patterns of cooling and contraction of the upper atmosphere are emerging from model studies and observations, consistent with a strong connection to changes in the lower atmosphere. Recent changes in noctilucent cloud distributions, now observed on a global scale by the AIM satellite (see figure above), are thought to be symptomatic of cooling temperatures in the upper atmosphere. Rising greenhouse gas concentrations alter the ionosphere in a variety of ways and could be transmitted to the magnetosphere. These changes may have unforeseen consequences for space-related technologies and societal infrastructures.
