In 1756, Black proved that carbon dioxide (which was then called "fixed air") occurred in the atmosphere and that it could form other compounds. He also identified carbon dioxide in the breath exhaled by humans. The first practical use of carbon dioxide can be traced to an invention made ...

to question how increasing carbon dioxide —a frequently cited cause for global warmingnow and in the distant past — factored into the end of the last ice age. Global warming skeptics have also cited this as evidence carbon dioxide produced by humans is not responsible for modern global ...
What does carbon dioxide have to do with humans? Carbon dioxide acts as a simple asphyxiant; in other words, as CO2 levels in a closed room rise, carbon dioxidereplaces the oxygen your body needs. When your body can't get oxygen, it slows down and does not function properly. Because ...
D If humans pump enough carbon dioxide (CO,) into the atmosphere,stratocumulus clouds (层积云) could disappear, and the Earth's temperature could climb sharply to heights not predicted in current climate models. It would burn the planet. That's the conclusion of a paper published in the jou...
