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.
CO2Now.org distributes the world's latest data for atmospheric CO2 as measured at the Mauna Loa Observatory in Hawaii. This is where high-precision CO2 monitoring was started in March 1958 by Dr. Dave Keeling of the Scripps Institution of Oceanography. The Mauna Loa Observatory is a remote location where CO2 is well mixed in the atmosphere, more than two miles above sea level.
Widget code for PPM CO2 widgets was updated in November 2015. At the same time, the PPM web widgets moved to Show.earth, the new "home of the CO2 widgets."

After 7 years of re-posting and re-distributing the latest readings for atmospheric CO2, CO2Now.org has moved to CO2.earth. All widgets at CO2Now.org are 'moving up' as 2015 comes to a close. Here's how:
Widget code is being upgraded to ensure compatibility with newer, 'responsive' websites that are optimized to perform on devices with a wide range of screen sizes.
The widgets get their own website: Show.earth. This is a new 'sibling site' for CO2.earth. It is now being set up to enable people to show the latest indicators of planetary health. CO2 web widgets are only the beginning.
Widgets are available in more sizes. (The PPM CO2 widget is now available in 20 sizes from 30 pixels wide to 1000 pixels wide!)
Old Widget Code
If you use web widget code from CO2Now.org, the widget on your site or blog will continue to update automatically throughout 2016. In December 2015, "click throughs" from CO2Now-sourced widgets will be redirected to CO2.Earth.
A plan to phase out these widgets will be developed late in 2016. Old CO2Now widgets may stop working during the 2017 calendar year.
Take advantage of new, improved widget code at the Show.earth site. Upgrade your widget code at your earliest convenience. You will be helping more people access an important, bigger picture on the changing health of our planet--and the conditions we need to create to achieve stabilization.

The Rio 92 CO2 widget takes its name from the 1992 Earth Summit in Rio de Janeiro, a hopeful and key event in the history of humanity's response to the problems of global warming and climate change. This is also the point when countries started to sign the United Nations Framework Convention on Climate Change (UNFCCC).
Did you know that atmospheric CO2 was 364 parts per million (ppm) during the Earth Summit in June 1992? In the past decade, atmospheric CO2 has been rising about 1.9 ppm per year. This is the fastest rate since scientists started using high-precision instruments to take CO2 measurements directly from the Earth's atmosphere.
Rising levels of atmospheric CO2 are at the heart of humanity's most significant sustainability problems. Changing this trend is key to ending global warming, climate change and ocean acidification. Use this rounded, 92 x 92 widget on your website to raise the profile of the world's most current data for atmospheric CO2. Let it be known that more needs to be done to make planet Earth a safe and stable place for raising a civilization.
Adding a widget is easy. Simple instructions and code for the Rio 92 widget are provided below.
This series of CO2 widgets is named after Jule Charney, the distinguished MIT meteorologist who led a nine-member Ad Hoc Group of Carbon Dioxide and Climate. This group was appointed by US President Jimmy Carter in 1979. After meeting for five days at the National Academy of Science's summer study center, in Woods Hole, Massachussetts, the group affirmed, "If carbon dioxide continues to increase, the study group finds no reason to doubt that climate change will result and no reason to believe that these changes will be negligible."
To add a Charney widget to your site, simple instructions and html code are provided below.
The Tyndall series of CO2 widgets is named in honour of John Tyndall. This is the Irish scientist who, in 1859, built the world's first ratio spectrophotometer. With this instrument, Tyndall identified the natural greenhouse effect that is now recognized as an essential condition of life on Earth.
Like all CO2Now widgets, the Tyndall widgets are udated in the second week of every month to keep the Earth's latest data for atmospheric CO2 on continous display. The colourful and informative Tyndall widgets are available in seven sizes, from 144 pixels wide to 200 pixels wide. To add one of these widgets to a website, use the code and simple installation instructions below.
The Pro Oxygen 300 widgets are displayed on every page of CO2Now.org. Add the widget to your website or blog, and the Earth's most current data for atmospheric CO2 will not just get displayed. The data will be updated each month.
