By ‘great’ I mean not only the importance for many current environmental issues, like climate change and the massive greenhouse gas increases, but great in the sense that solving the mysteries of their occurrence requires breakthroughs from so many different fields of science.
I did post-graduate research on ice ages with a climatologist, Barry Saltzman, who was a co-discoverer of chaos (with Ed Lorenz) and who spent much of his later career on ice age science. I remember marveling with him over the almost ridiculous number of disciplines ice-age science involves: geology, glaciology, climatology, atmospheric physics and chemistry, oceanography, astronomy, geochemistry, biology, geomagnetism, meteorology, nonlinear mathematics and probably other fields I’m not listing!
