In news: Global Carbon project released the Global Carbon Budget for 2019.

More about the project:

  • The Global Carbon Project is a Global Research Project of Future Earth and a research partner of the World Climate Research Programme. It was formed to work with the international science community to establish a common and mutually agreed knowledge base to support policy debate and action to slow down and ultimately stop the increase of greenhouse gases in the atmosphere.
  • The Global Carbon Project was established in 2001 by a shared partnership between the International Geosphere-Biosphere Programme (IGBP), the International Human Dimensions Programme on Global Environmental Change (IHDP), the World Climate Research Programme (WCRP) and Diversitas.
  • The scientific goal of the Global Carbon Project is to develop a complete picture of the global carbon cycle, including both its biophysical and human dimensions together with the interactions and feedbacks between them. 

Key highlights of the budget:

  • Global CO2 emissions from fossil fuels and industry have increased every decade. 
  • CO2 removals by natural sinks: Of the total emissions from human activities during 2009-2018, 45?cumulated in the atmosphere, 23% in the ocean and 29% on land. Atmospheric CO2 concentration in 2019 is 47?ove pre-industrial levels. 
  • The cumulative carbon emissions are the sum of the total CO2 emitted during a given period of time. Total cumulative emissions from 1850 to 2019 were 1649 GtCO2 from fossil fuels and industry, and 751 GtCO2 from land use change.
