Figure 1: Historical concentrations for CO2, CH4, and N2O from this data compilation (see Fig. 6b in Meinshausen et al. (2017) (link: geosci-model-dev.net/10/2057/2017))

Greenhouse Gas Fact Sheets
Scientists Zebedee Nicholls and Malte Meinshausen at the University of Melbourne present comprehensive, interactive plots, factsheets, future projections and data download options for atmospheric surface concentrations of 43 greenhouse gases and 3 equivalent gas time series from 2000 years ago to the year 2500.

The projections including the 9 so-called SSP scenarios for all 43 greenhouse gases, (link: geosci-model-dev.net/9/3461/2016), provide the basis for the science communities’ research and analysis in preparation for the Sixth IPCC Assessment Report (link: ipcc.ch).
