CO2 ATMOSFÉRICO PPM

Yearly Carbon Dioxide Peak | Climate Matters

12/05/2021· According to data from NOAA, daily peak CO2 reached just over 421 ppm (parts per million), up from 417 ppm last year at Mauna Loa. It’s not just the record CO2 levels, but also the record pace. The Carbon Skyscraper graph focuses on CO2 change rates over the last 800,000 years, capturing the incredible speed and amount of CO2 that humans are pumping into the atmosphere.

About: Carbon dioxide in Earth's atmosphere

La concentración media diaria de CO2 atmosférico en Mauna Loa superó por primera vez las 400 ppm el 10 de mayo de 2013. Actualmente está aumentando a razón de aproximadamente 2 ppm/año y se está acelerando. Se estima que el 30-40 % del CO2 emitido por los humanos a la atmósfera se disuelve en los océanos, ríos y lagos, lo que contribuye a la acidificación del océano.

Carbon dioxide in Earth's atmosphere - Wikipedia

Carbon dioxide concentrations have shown several cycles of variation from about 180 parts per million during the deep glaciations of the Holocene and Pleistocene to 280 parts per million during the interglacial periods. Following the start of the Industrial Revolution, atmospheric CO 2 concentration increased to over 400 parts per million and continues to increase, causing the phenomenon of global …
