The crazy scale of human carbon emission

by Caleb A. Scharf, Scientific American Want some perspective on how much carbon dioxide human activity produces? Here it is. A major question in astrobiology is how we’ll measure and interpret the atmospheric composition of any Earth-analog worlds we find out among the exoplanets. We pretty much know the technical requirements: big telescopes, excellent spectroscopic instruments, […]

Carbon credits likely worthless in reducing emissions, study says

by Nicholas Kusnetz, Inside Climate News Schemes allowed by the Paris climate agreement won’t help countries reach their reduction targets, European report says, and should be phased out. As nations grapple with how they can slash their emissions as part of the Paris climate agreement, some may use international credit schemes that were approved in […]
