CO2 Rise and Ionosphere: Threat to Space Communications
Rising CO2 and a Cooling Upper Atmosphere: Why Space Communications Could Be at Risk As global warming accelerates, researchers are turning their attention to how atmospheric changes affect the ionosphere, a region roughly 60 to 1,000 kilometers above Earth. A team from Kyushu University has found that higher carbon dioxide (CO2) levels, while warming Earth’s…
