Levels of the greenhouse gas carbon dioxide eclipsed 420 parts per million for the first time in human history in 2021. Scripps Institution of Oceanography updated this animation, which explains the rise of carbon dioxide concentration in the atmosphere over the past 300 years and the measurement our researchers collect at Hawaii’s Mauna Loa, known as the Keeling Curve. When … Read More
The COVID-19 pandemic caused carbon dioxide (CO2) emissions from fossil fuels to drop in 2020 by seven percent compared to 2019. This decrease in emissions slowed the increase in atmospheric CO2 compared to what would have occurred without the pandemic. It was too small and too brief, however, to stand out strongly in individual CO2 records, such as the Keeling … Read More
Scripps Oceanography lab monitoring atmospheric CO2 named National Historic Chemical Landmark
The rate of growth in carbon dioxide concentrations in the atmosphere has accelerated since the beginnings of the Keeling Curve.
Breakthrough after field project collects richly detailed ice core records from Antarctica
Supports continued operation of the iconic measurement series
The story of the Keeling Curve is beautifully animated in this new video. The American Museum of Natural History will host a Google+ Hangout Sept. 9, 2014 on the topic of the Keeling Curve. [youtube https://www.youtube.com/watch?v=0Z8g-smE2sk&w=560&h=315]
