CO2 Now

 

What the world needs to watch

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.

Why is CO2 significant?
Carbon dioxide (CO2) is the chief greenhouse gas that results from human activities and causes global warming and climate change. To see whether enough is being done at the moment to solve these global problems, there is no single indicator as complete and current as the monthly updates for atmospheric CO2 from the Mauna Loa Observatory.
 
 
 
 
What is the current trend?
The concentrations of CO2 in the atmosphere are increasing at an accelerating rate from decade to decade.   accelerating from decade to decade.   The latest atmospheric CO2 data is consistent with a continuation of this long-standing trend.
   
 
 
What level is safe?
The upper safety limit for atmospheric CO2 is 350 parts per million (ppm). Atmospheric CO2 levels have stayed higher than 350 ppm since early 1988.
