Why not use a clever mathematical trick?

RealClimate - There is a clever mathematical trick for comparing different data sets, but it does not seem to be widely used. It is based on so-called empirical orthogonal functions (EOFs), which Edward Lorenz described in a Massachusetts Institute of Technology (MIT) scientific report from 1956. The EOFs are similar to principal component analysis (PCA). The EOFs and PCAs provide patterns of spatio-temporal covariance structure. Usually these techniques are applied to datasets with many … [Read more...]

Further perspectives on pandemics and climate change

RealClimate - I have recently been asked whether the present corona pandemic will have any consequence on climate change. Gavin has already discussed the coronavirus and climate here on RealClimate, and I like to follow up on his post. Rather than emphasising analogies, I would highlight additional common denominators between the present world-wide Covid-19 pandemic and climate change. My first reaction is that the present crisis has taught us the value of knowledge and science. It is also … [Read more...]
