Carbon dioxide a cikin sararin samaniya na Duniya

A cikin yanayi na ,  gas ne wanda ke taka muhimmiyar rawa a cikin tasirin greenhouse, sake zagayowar carbon, photosynthesis, da sake zagayolar carbon na teku. Yana daya daga cikin manyan iskar gas guda uku a cikin sararin samaniya na Duniya. Adadin carbon dioxide (CO) a cikin yanayi ya kai 427 ppm (0.0427%) a kan wani tushe a cikin 2024, wakiltar 3341 gigatonnes na CO2. Wannan karuwa ne na 50% tun farkon Juyin Juya Halin Masana'antu, daga 280 ppm a cikin shekaru 10,000 kafin tsakiyar karni na 18. Karin ya faru ne saboda aikin ɗan adam.

Karin yawan CO2 da sauran iskar gas mai ɗorewa kamar methane yana ƙara sha da fitar da radiation na infrared ta yanayi. Wannan ya haifar da hauhawar matsakaicin zafin jiki na duniya da ƙarancin teku. Wani sakamako kai tsaye shine tasirin taki na CO2. Karin yawan CO2 na yanayi yana haifar da ƙarin tasirin canjin yanayi akan muhalli da yanayin rayuwar mutum.

Since the start of the Industrial Revolution, atmospheric CO2 concentration have been increasing, causing global warming and ocean acidification. In October 2023 the average level of CO2 in Earth's atmosphere, adjusted for seasonal variation, was 422.17 parts per million by volume (ppm)."Parts per million" refers to the number of carbon dioxide molecules per million molecules of dry air.  Updated monthly. Figures are published monthly by the National Oceanic & Atmospheric Administration (NOAA). Latest figure, and graphs of trend; frequently updated The value had been about 280 ppm during the 10,000 years up to the mid-18th century.
