Rising CO2 and the Ionosphere: How Global Warming Could Disrupt Shortwave Space Communications
Global warming reaches new frontiers: space communications under threat As the planet warms, scientists are uncovering a surprising wrinkle in how climate change could affect our ability to communicate through space and near-space environments. A team from Kyushu University has found that rising carbon dioxide (CO2) levels in Earth’s atmosphere may cool the upper atmosphere…

Rising CO2 Could Disrupt Space Communications via Sporadic-E Ionosphere Changes
Overview: A Climate Link to Space-Weather Disruptions As the planet warms, researchers are uncovering how rising carbon dioxide (CO2) levels may extend their influence beyond the surface. A team from Kyushu University has reported that higher CO2 concentrations can cool the ionosphere, a region about 100 kilometers above Earth’s surface where charged particles interact with…
