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.

CO2 Data Set:

Original Scripps data file dated  Thursday May 2, 2013

 
 
Measuring Location:

Mauna Loa Observatory, Hawaii

 

 
 
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.   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.

 

 
Current Data for Atmospheric CO2


The world's most current data for atmospheric CO2 is measured at the Mauna Loa Observatoy in Hawaii.  Measurements are made and reported independently by two scientific institutions:  Scripps Institution of Oceanography and the National Oceanic and Atmospheric Administration (NOAA).  Monthly data is posted below.

Annual Levels for Atmospheric CO2

Atmospheric CO2 (ppm)The 2012 average annual concentration of CO2 in the atmosphere (Mauna Loa Observatory) is 393.84 parts per million (ppm).   The 2011 average is 391.65 ppm.  

For the past decade (2003-2012) the average annual increase is 2.1 ppm per year.  The average for the prior decade (1993-2002) is 1.7 ppm per year.    Annual data for 2012 was first posted January 3, 2013, by the Scripps Institution of Oceanography in the United States. 

Since the 1958 start of precision CO2 measurements in the atmosphere, the annual mean concentration of CO2 has only increased from one year to the next.   The CO2 data below provide a simple view of the annual trend.

Global Temperature Update

 

Global Temperature

 

April 18, 2013

March 2013 tied March 2006 as the 10th warmest March since global temperature records began in 1880.  The coolest was March 1898

Annually, 2012 was the 10th warmest year since 1880.  Only one year during the 21st Century was warmer than 2012.     

 

"The science is sobering—the global temperature in 2012 was among the hottest since records began in 1880. Make no mistake: without concerted action, the very future of our planet is in peril."

~ Christine Lagarde, Managing Director,
International Monetary Fund

More details about global temperature are available in the State of the Climate reports (Global Analysis) at the NOAA-NCDC website. These reports present preliminary, global data that has been gathered from monitoring stations and leading institutions around the world. The reports include a Global Hazardssection that gives a global update on drought & wildfires, flooding, storms, severe winter weather, and ecosystems impacts. A Snow and Ice section reports on snow cover in the Northern Hemisphere and sea ice extent in the Northern and Southern Hemispheres.

NOTE: Global temperatures set out in the CO2Now graphic (above) are computed from preliminary NOAA estimates of global average temperature for the 20th century and adding the current 20th-century anomaly.

Global CO2 Budget 2010

GlobalCarbonProject.org posted data for the 2010 Global Carbon Budget on December 5, 2011.  Key findings are listed here:

* CO2 emissions grew 5.9% in 2010 to reach 9.1 GtC (33.5Gt CO2), overcoming a 1.4% decrease in CO2 emissions in 2009 

* Including land-use change and deforestation, in 2010 emissions reached 10.0 GtC (36.8 Gt CO2)

* As of 2009 developing countries now emit more than developed countries in terms of consumption, and China now emits more than the US in terms of consumption
