Carbon dioxide is an important greenhouse gas that helps to trap heat in our atmosphere. Without it, our planet would be inhospitably cold. However, an increase in CO 2 concentrations in our atmosphere is causing average global temperatures to …
Carbon Dioxide - Climate Change: Vital Signs of the Planet
Carbon dioxide (CO 2) is an important heat-trapping gas, also known as a greenhouse gas, that comes from the extraction and burning of fossil fuels (such as coal, oil, and natural gas), from wildfires, and natural processes like volcanic eruptions.
Understanding the basics of carbon dioxide - NOAA Research
2024年6月28日 · Carbon dioxide is a gas produced when an organic carbon compound (such as wood) or fossilized organic matter (such as coal, oil, or natural gas) is burned in the presence of oxygen. Carbon dioxide is removed from the atmosphere by “sinks”, such as absorption by seawater and photosynthesis by plants and plankton .
