The State of Our Climate
Emissions


March 2016 research:  Human carbon release
​rate is unprecedented in the past 66 million years
​ of Earth's history- about 10 times faster 
Total CO2 emission
​by source (GCP 2021)
3 Aug. 2020 RCP 8.5 tracks emissions 
​ of worst-case cumulative CO2 emissions
​scenario- continues to apply

World Bank Greenhouse gas emissions
​to 2020 (main GHGs and CO2 eq)
Fossil fuel CO2 emissions Annually 
​Global Carbon Project
Methane and nitrous oxide emissions also
​ Global Carbon Budget (2022)
IPCC AR6 Global GHG emissions (2019)
Global methane emissions
​Tracking worst-case scenario 
(Global Carbon Project 2020)​
Now wetland Feedback ​emissions 
Global nitrous oxide emissions
​Tracking worst-case scenario  
Soil feedback emissions​
(Global Carbon Project 2020​)
Black carbon (soot) aerosol emissions 
CO2 equivalent emissions (all GHGs) 
Global greenhouse gas emissions are all all record high, increasing as fast as ever
Fossil fuel CO2 emissions in 2023

CO2 lasts long in the atmosphere - 100s of years.
So CO2 emissions are highy persistent and cumulative ​in the ​atmosphere.
​In like manner so is nitrous oxide  
Accelerating increase of cumulative fossil fuel CO2 emissions

Emissions are still being increased
​when they had to be declining
Individual GHG emissions also at EDGAR
