Dr. João Teixeira, a Member of JIFRESSE Science Steering Committee, led a study to directly measure for the first time how increasing atmospheric carbon dioxide (CO₂) reduces Earth's ability to emit infrared radiation into space, a key driver of global warming. Their results, which align closely with theoretical predictions, provide robust experimental confirmation of this core mechanism underlying climate change.
