March 2020 CO2 Levels at Mauna Loa Show No Obvious Effect from Global Economic Downturn

From Dr. Roy Spencer’s Blog April 7th, 2020 by Roy W. Spencer, Ph. D. The COVID-19 disease spread is causing a worldwide shutdown in economic activity as business close, airlines cancel flights, and people shelter in their homes. For example, there was a 28% decline in global commercial air traffic in March 2020 compared to…

A Simple Model of the Atmospheric CO2 Budget

Reposted from Dr Roy Spencer’s blog April 11th, 2019 by Roy W. Spencer, Ph. D. SUMMARY: A simple model of the CO2 concentration of the atmosphere is presented which fairly accurately reproduces the Mauna Loa observations 1959 through 2018. The model assumes the surface removes CO2 at a rate proportional to the excess of atmospheric…

Mauna Loa Daily Meteorology

Guest Post by Willis Eschenbach As a confirmed data junkie, I’m fond of hourly data. The interesting processes in the climate system unfold on the scale of minutes and hours, not years. So I picked up a project I’d started a while ago, but as is too often the case I’d gotten sidetractored by ……

NSF says biosphere is breathing in CO2 more deeply

Press Release 13-139 Seasonal carbon dioxide range expanding as more is added to Earth’s atmosphere Northern Hemisphere land-based ecosystems “taking deeper breaths,” scientists find Levels of carbon dioxide in the atmosphere rise and fall each year as plants, through photosynthesis and respiration, take up the gas in spring and summer, and release it in fall…

Premature 400 PPM fail-a-bration

It seems we didn’t reach 400PPM last week after all. The data has been revised. Ooops. ‘Carbon dioxide measurements in the Earth’s atmosphere did not break the symbolic milestone of 400 parts per million at a Hawaiian observatory last week, according to a revised reading from the nation’s climate observers.
