Scientists using NASA’s James Webb Space Telescope have captured definitive evidence of carbon dioxide in the atmosphere of a planet beyond our solar system.
If researchers could find a way to chemically convert carbon dioxide into fuels or other products, they might make a major dent in greenhouse gas emissions.

Scientists long-standing mystery atmospheric carbon dioxide lower during ice ages
2019/10/28
Since scientists first determined that atmospheric carbon dioxide was lower during ice ages than during warm phases, they have looked at why, theorizing that it may be a function of ocean circulation,...
