Give ten seconds a day to consider the Earth's changing vital signs.  

: ppm CO2
Change:   %

 Updates are scheduled for approximately 3:35 am each day, local Hawaii time (UTC -10).

Note: This webpage is testing automated updates.  On other pages like "Daily CO2," updates are posted by a person.
We're creating and testing automations so the CO2 readings at CO2.Earth are always updated as early as possible.


Make CO2 Tracking a Personal Habit That Starts Local Then Goes Global
Please share CO2 updates with friends, family and audiences you have a connection with.  It's a quick way to take stock of what's going on right now with the people-planet relationship.  It's a small yet vitally important thing that anyone or any group can start doing.  Simple, regular acts of sharing and reflecting supports more of the kinds of discussions and decisoins that are needed if human progress is to achieve an alignment with planetary conditions for continuing to sustain prosperous economies, habitable environments and flourishing societies.



Promoting Local, Daily Updates on Planetary Health


Daily CO2 readings from the Mauna Loa Observatory are the best vital signs indicator of what's actually going on--in real time--with the health of the planet.  Why?  Because CO2 changes in the atmosphere are more consequential than any other to the planet's climate and environmental conditions for sustaining abundant, diverse and intelligent life in the short and long term.  And because the Mauna Loa record is the longest set of high-precision readings we have.   And there's at least one more reason.  Year-over-year comparisons of atmospheric CO2 readings at a single location on the planet show us the direction of changes in real time.  

The rise of atmospheric CO2 is relentless and accelerating.   CO2 updates are not exactly news and the information is definitely not good.  But it's the leading trend for leaders to end.  By leaders, I include people alarmed by what is going on and toiling to do all they can to influence change from the bottom up.  And I mean leaders with means and placings to help people, organizations and countries scale up to the challenge.

To do all that and transform bad news CO2 updates into daily confirmations of humankind's collective success, the world needs all eyes on CO2 in the atmosphere.  

Whether your day is spent making ends meet or jam-packed with high-level meetings, there should be few reasons why a person cannot take ten seconds a day to get an update on the current CO2 level and its change from the year before.   But the updates are not yet featured by traditional media, social media, online platforms, major websites or widely-used apps.  

That's why a few people are combining different talents to promote daily updates and make it easy for communicators far and wide to connect their communications content with glboal changes and our shared challenges and efforts to end the rise of planet-heating gases in the atmosphere.  There's room for more volunteers to assist in these efforts.  But for now, here's the original crew of people who are fitting in a bit of time for this project on top of busy work and family commitments:

Mike McGee, M.A. E.E.C. has, since 2007, been continually re-posting CO2 readings to Earth's CO2 Home Page--permanently located at CO2.Earth.  This homepage and site is a DIY bootstrapped effort that evolved from other sites: (2007 - 2008) and (2008 - 2015).   Now the mission is to use CO2.Earth as a springboard for creating a platform for productive collaborations that extends the visiabiity of CO2 and other planet-heating gases.  Admittedly ambitious the intention is to advance constructive, rapid and peaceful transformations with widespread benefits short and long terms.  Spreading daily CO2 updates has become a core part of that effort.  Mike lives and works in Victoria, BC, Canada. 

Professor Rick Kool is the lead instigator and evangelist who, since March 2019, has been leveraging his multitude of connections and reaching out to traditional media and others to add daily CO2 readings to their market updates, weather updates and even church sermons!  The rejections outnumber the acceptances, but Rick is more relentless in his efforts to see this happen than, perhaps, the steady, accelerating rise of CO2 in the atmosphere. The implications are not just economic, environemntal and social.  They have a moral and spiritual dimension.  Rick lives and works in Victoria, BC, Canada. 

Adam Davey, B.Sc. (Hon.) wears the important technology-solutions hat for this project.  As a seasoned data and technology professional, and principal for NumberLens Limited, Adam has been developing and refining backend prototypes to enable our reliable delivery of accurate CO2 data and informaiton that CO2.Earth and others need to enable the widespread display and reporting of regular CO2 updates.   Adam lives and works in Malton, North Yorkshire, England.  


Sample Radio Market Updates Mix the Dow Jones, Oil and CO2

Why CO2 Updates?  And what do they sound like on the radio?  Below, we've compiled a few articles and sound clips that start to answer these questions.

First up, here's a sample from CBC Radio with what may be the world's first market update on radio to include daily CO2 updates with latest numbers for the the Dow and NASDAQ indeces and the price of light crude oil. 



For more on how CO2 fits with a traditional stock market update, what the CO2 numbers mean, and what people think, review the articles and radio interviews below.

When the market goes up, so do CO2 emissions, says Rick Kool.  September 24, 2019.

CBC Radio One  The relationship between the stock market and CO2 emission levels On the Island with Gregor Craigie
Host Gregor Craigie spoke with Rick Kool, a professor in the School of Environment and Sustainability at Royal Roads University. Professor Kool argues that media outlets should give a daily report on the amount of CO2 in the atmosphere, alongside market numbers, to highlight the connections between industrial society and the atmosphere. 8 minutes.

What Next?

The early uptake and interest in daily number updates inspires us to do more.  We're innovating ways to make it easier to see and spread vital signs updates in many ways, places and settings.  If this project piques your interst, we'd love to hear how you are helping or could help others to bring daily vital signs numbers on air, into a wider view and in more conversations.  Feedback, suggestions and requests are welcome. Feel free to direct them them to either Mike, Rick or Adam at This email address is being protected from spambots. You need JavaScript enabled to view it., or by leaving a message at 604-900-2321.  In any case, expect to hear and see more CO2 updates in the future.  Thanks to Gregor Craigie, we know it can be done in just ten seconds a day.
