2018 visualisation update

With 2018 coming towards an end, the World Meteorological Organisation (WMO) released their provisional State of the Climate report. The WMO asked whether Climate Lab Book could provide some updated graphics, also reproduced here.

  1. Hi
    Thank you for sharing!
    Which tool can plot the Circle Graph? I want to plot a Circle Graph for my data but I don’t know a tool for plotting it so I decided to develop a new tool to plot the Circle Graph. If you have any information about it please share it
    Thanks.

  2. ps – another Q – correct citation for 1850-2018 warming stripes?
    Climate Lab Book webpage + reference to Morice et al. 2012?

    Morice et al is from 2012, plus don’t show the warmig stripes?

    Morice, C. P., Kennedy, J. J., Rayner, N. A., and Jones, P. D. (2012). Quantifying uncertainties in global and regional temperature change using an ensemble of observational estimates: The HadCRUT4 data set. Journal of Geophysical Research: Atmospheres, 117(D8).
