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. |

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.

The 2011 average annual concentration of CO2 in the atmosphere (Mauna Loa Observatory) is 391.57 parts per million (ppm). The 2010 average is 389.78 ppm.
For the past decade (2002-2011) the average annual increase is 2.07 ppm per year. The average for the prior decade (1992-2001) is 1.6 ppm per year. Annual data for 2011 was first posted January 5, 2012, by the National Oceanic and Atmospheric Administration (NOAA) 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. |

May 15, 2012
In April 2012, the average temperature of Earth's Northern Hemisphere was the warmest of any April in the past 133 years.
Globally, April 2012 marks the fifth warmest April since temperature records began in 1880. It was the 326th straight month with a global temperature above the average for the 20th century.

Data and information was first posted May 15, 2012 by National Oceanic and Atmospheric Administration (NOAA) and its National Climate Data Center (NCDC) in the USA.
Annually, 2011 is the 11th warmest year on record. The year 2010 tied with 2005 as the warmest year.
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
