   - **Local, interannual variability**. This built on some work by Chris and Kira analysing changes in interannual variability across PMIP3 simulations. An additional stream of analysis showed that the modes of climate variability appear fairly consistent across multiple climate states (with a focus on mediterranean climates). This is being coordinated by Heidelberg, with contributions from Arizona, AWI, UCL & Yale.    - **Local, interannual variability**.

-=== El Nino - Southern Oscillation === 
 There has been much work looking at ENSO changes in different experiments (see review by [[https://​www.mdpi.com/​2073-4433/​9/​4/​130/​htm|Lu et al., 2018]]). Looking across these simulations in PMIP3/4 would be interesting. This was done for PMIP2 ([[https://​link.springer.com/​article/​10.1007/​s00382-007-0320-3|Zheng et al., 2008]]). An update that includes the lig127k, midPliocene-Eoi400 and, most importantly,​ the future would be warranted. Sufficient post-processed fields are likely available from the working group'​s archive at [[http://​www2.geog.ucl.ac.uk/​~ucfaccb/​PMIPVarData/​|www2.geog.ucl.ac.uk/​~ucfaccb/​PMIPVarData]] to fuel a paper. A collective is being pulled together at present: contact [[mailto:​c.brierley@ucl.ac.uk|Chris]] for more information. There has been much work looking at ENSO changes in different experiments (see review by [[https://​www.mdpi.com/​2073-4433/​9/​4/​130/​htm|Lu et al., 2018]]).

 +=== A possible ​North Atlantic Oscillation === 
 +**//Chris currently has an MSc student looking at this, but we will need help to convert into a paper//**
 This would focus on describing changes in the North Atlantic Oscillation across past and future equilibrium simulations. It would use PMIP3/CMIP5 and whatever is available for PMIP4/​CMIP6. It would look at the piControl, midHolocene,​ lig127k, lgm, midPliocene-Eoi400 and abrupt-4xCO2 experiments. Could base all the analysis on DJF season. Is there a role for analysing the past1000 simulations?​ This would focus on describing changes in the North Atlantic Oscillation across past and future equilibrium simulations.
