Eunice Newton Foote was the first to discover the alarming effects of carbon oxides in the atmosphere in 1856. Today this phenomenon is known as the greenhouse effect. It can be said that then also began the denial of the climate crisis that continues to this day

"Swiss cheese" holes in the south pole of Mars. The white substance in the picture is dry ice - made of carbon dioxide. The depressions in the dry ice layer reach a depth of only 10 meters. They are formed in the red summer season, when the sun's rays strike at a low angle in the polar region, and reach mainly the steep walls of the depressions - which encourages development laterally rather than in depth. The photograph, in its full resolution, has a resolution of 50 centimeters per pixel. Taken on March 25, 2017 by NASA's Mars orbiter MRO. Credit: NASA/JPL-Caltech/Univ. of Arizona.

Porous catalysts that capture carbon dioxide and convert it into a useful fuel, analogous to the ability of plants to convert carbon dioxide into biomass. Computer modeling shows how the functional groups inside a porous solid substrate can be tuned to obtain accelerated reactions to split carbon dioxide and produce useful products (Design: Jingyun Ye).
