Global warming is mainly the result of CO2 levels rising in the Earth’s atmosphere. Both atmospheric CO2 and climate change are accelerating. Climate scientists say we have years, not decades, to stabilize CO2 and other greenhouse gases.
To help the world succeed, CO2Now.org makes it easy to see the most current CO2 level and what it means. So, use this site and keep an eye on CO2. Invite others to do the same. Then we can do more to send CO2 in the right direction.
Watch CO2 now and know the score on global warming, practically in real time.
Seasonal Fluctuation of Atmospheric CO2
Seasonal fluctuation in atmospheric carbon dioxide (CO2) at the Mauna Loa Observatory
Points to notice: annual fluctuation of CO2, net annual increase on a global level, and
the greater range of fluctuation at northern latitudes (where most of Earth's land and vegetation exist).
