CDIAC Carbon Dioxide Information Analysis Center
The Carbon Dioxide Information Analysis Center (CDIAC), located at the U.S. Department of Energy‘s (DOE) Oak Ridge National Laboratory (ORNL), is the primary climate change data and information analysis center for DOE. CDIAC is supported by DOE’s Climate and Environmental Sciences Division within the Office of Biological and Environmental Research (BER).
CDIAC’s data holdings include estimates of carbon dioxide emissions from fossil-fuel consumption and land-use changes; records of atmospheric concentrations of carbon dioxide and other radiatively active trace gases; carbon cycle and terrestrial carbon management datasets and analyses; and global/regional climate data and time series.
NOAA ESRL Trends in Atmospheric Carbon Dioxide – Mauna Loa Observatory
At NOAA’s Earth System Research Laboratory (ESRL), scientists study atmospheric and other processes that affect air quality, weather, and climate. By better understanding the dynamic Earth system, we can better understand what drives this afternoon’s haze, next month’s hurricanes, and next century’s climate. ESRL researchers monitor the atmosphere, study the physical and chemical processes that comprise the Earth system, and integrate those findings into environmental information products. Our work improves critical weather and climate tools for the public and private sectors, from hourly forecasts to international science assessments with policy-relevant findings.
IEA CO2 Emissions From Fuel Combustion Highlights Report
In the lead-up to the UN climate negotiations in Paris, the latest information on the level and growth of CO2 emissions, their source and geographic distribution will be essential to lay the foundation for a global agreement.
CDIAC Global Carbon Budget
The Global Carbon Budget is a collaborative effort of the global carbon cycle science community coordinated by the Global Carbon Project.
The global carbon budget refers to the mean, variations, and trends in the anthropogenic perturbation of CO2 in the atmosphere, referenced to the beginning of the industrial era. It quantifies the input of CO2 to the atmosphere by emissions from human activities, the growth of CO2 in the atmosphere, and the resulting changes in land and ocean carbon fluxes in response to increasing atmospheric CO2 levels, climate change and climate variability, and other anthropogenic and natural changes. An understanding of this perturbation budget over time and the underlying variability and trends of the natural carbon cycle are necessary to understand and quantify climate-carbon feedbacks.
WRI CAIT Climate Data Explorer
CAIT is made up of a suite of tools that allow users to utilize the data to understand considerations of equity in climate negotiations, see transparency and available information in country climate action comitments, interact with historical emissions data, and dive into the methodologies behind future emissions projections. CAIT allows national governments, international organizations and independent researchers to perform relevant analysis and promote efficient action on climate change.
