I think the volcano case illustrates that there is still a lot about aerosol dynamics as captured (or not) in climate models that is still uncertain but that plays a meaningful role in surface climate outcomes relevant to trying to deploy SAI.

IMO there is a pretty big difference between 'here is what we think could happen if the thing that is already happening continues' vs. 'here is what we think might happen when 'we' do something intentionally that has large uncertainties and has massive ethical and justice issues'.

The defense that this was just an adjustment based on better data is self-serving BS.

We do *not* know what the 100-yr flood level is - even if we had perfect DEMs.

Even if we had perfect historical data, non-stationarity means we don’t know what the level is *now*, let alone in the future.

“Now we have digital imagery. We have elevation to a 10th of an inch. We know what's actually in a 100-year floodplain."

🌳💧📊 #PhDAlert! MSc in #ForestEcology or #EnvironmentalSciences? Excellent analytical and statistical skills in time-series analysis and experience with #treering methods🪵? We offer a #PhD position in #Dendroecology: apply.refline.ch/273855/1795/... #dendrosciences #ecology #ScienceJobs

Job offer: PhD in Dendroecology (f/m/d)
You will be part of a project aiming to empirically disentangle atmospheric vs. soil drought impacts on intra- and inter-annual wood formation, and mechanistically model drought constraints on intra- and inter-annual tree growth dynamics (https://www.wsl.ch/en/projects/sad-tree) based on a unique monitoring network of 44 forest sites in Switzerland spanning 10 years of soil moisture and atmospheric climate data. In this context, you will contribute to the establishment and analysis of intra- and inter-annual time series of tree growth based on dendrometer, tree rings, and quantitative wood anatomy (QWA).

You will be responsible for establishing improved empirical relationships of tree growth-environment interactions based on the long-term integrative Soil-Plant-Atmosphere-Continuum dataset (tree & stand traits, physical environment), analyzing: intra-annual water- and growth-related stem radius changes from dendrometer measurements, early-season wood anatomy related to water transport and rehydration, and long-term drought effects on growth using tree-ring widths.

You have a Master's degree in forest ecology, environmental sciences, or equivalent. You should have excellent analytical and statistical skills in time-series analysis, preferably in dendrosciences and/or tree physiology. Ideally, you are proficient in programming and handling of large datasets, and have experience with tree-ring methods. You are able to efficiently expand and acquire knowledge in topics relevant to the project. You have a proficient command of written and spoken English, are able to work in a structured, efficient and independent manner, and have a high level of team spirit and have good communication skills.

A.E. Douglass (founder of the science of dendrochronology) got fired by Percival Lowell for questioning the existence of 'canals' on Mars. Douglass was out of science for many years before getting a position at the University of Arizona. He would be expected to teach physics & physical geography:
