  • From the Report, Chapter 10.5.2:

    If the conditions are suitable, emissions of soot and water vapour can trigger the formation of contrails (Kärcher 2018), which can spread to form extensive contrail-cirrus cloud coverage. Such cloud coverage is estimated to have a combined ERF that is about 57% of the current net ERF of global aviation (Lee et al. 2021), although a comparison of cirrus cloud observations under pre- and post-COVID-19 pandemic conditions suggest that this forcing could be smaller (Digby et al. 2021). Additional effects from aviation from aerosol-cloud interactions on high-level ice clouds through soot (Chen and Gettelman 2013; Zhou and Penner 2014; Penner et al. 2018), and lower-level warm clouds through sulphur (Righi et al. 2013; Kapadia et al. 2016) are highly uncertain, with no best estimates available (Lee et al. 2021).

    The 2 papers listed which quantify the effect:

    • Lee, D.S. et al., 2021: The contribution of global aviation to anthropogenic climate forcing for 2000 to 2018. Atmos. Environ. , 244, doi:10.1016/j.atmosenv.2020.117834. Link to paper
    • Digby, R.A.R., N.P. Gillett, A.H. Monahan, and J.N.S. Cole, 2021: An Observational Constraint on Aviation-Induced Cirrus From the COVID-19-Induced Flight Disruption. Geophys. Res. Lett. , 48(20) , e2021GL095882-e2021GL095882, doi:10.1029/2021GL095882. Link to paper




  • Walking while concentrating on what i feel in different parts of my body helps me in high stress situations, and longer walks once in a while when I’m not completely stressed out helps clear my mind. swimming in thermal water also helps keep my overall stress level down when I’ve got enough capacity left to actually do it.

    so yeah, the right exercise customised to my actual capacity to do exercise helps a lot - but i have to allow myself to just stop doing it without beating myself up if I’m not up to it.
