The first talk of our seminar is now available to watch and discuss!

Abstract.The global warming crisis is part of a bigger transformation in which humanity realizes that the Earth is a finite system and that our population, energy usage, and the like cannot continue to grow exponentially. If civilization survives this transformation, it will affect mathematics - and be affected by it - just as dramatically as the agricultural revolution or industrial revolution. We should get ready!

Hi John, on your slides you cited "To understand ecosystems, ultimately will be to understand networks. — B. C. Patten and M. Witkamp"

Could you please share your thoughts, and references perhaps, about if/how this central role of networks resonates with Topology ? Is it an ultimate framework layer to you? And how important/useful could it be regarding studying Earth system ?

Thanks in advance, best

Condensed matter physicists are making great progress in climate science via topological modeling:

Delplace, Marston, Venaille: Topological Origin of Equatorial Waves

Quanta Magazine: Mathematicians Tame Turbulence in Flattened Fluids

To understand the role of condensed-matter physics in applied physics, this is an interesting read from last week's Physics Today: When condensed-matter physics became king

`> re *"... Topology ? Is it an ultimate framework layer to you? And how important/useful could it be regarding studying Earth system ?"* Condensed matter physicists are making great progress in climate science via topological modeling: Delplace, Marston, Venaille: [Topological Origin of Equatorial Waves](http://science.sciencemag.org/content/358/6366/1075) > "Topological effects that arise from material boundaries are well known in solid-state physics and form the basis for topological insulators. Delplace et al. describe atmospheric and ocean waves that appear to have a similar topological origin. The waves exist because of the symmetry-breaking nature of Earth's rotation, which allows certain fixed topological constraints on the system. These findings may be useful for understanding a wide variety of geophysical and astrophysical flows." Quanta Magazine: [Mathematicians Tame Turbulence in Flattened Fluids](https://www.quantamagazine.org/mathematicians-tame-turbulence-in-flattened-fluids-20180627/) > "By squeezing fluids into flat sheets, researchers can get a handle on the strange ways that turbulence feeds energy into a system instead of eating it away." To understand the role of condensed-matter physics in applied physics, this is an interesting read from last week's Physics Today: [When condensed-matter physics became king](https://physicstoday.scitation.org/doi/full/10.1063/PT.3.4110) > "The story of how solid-state physics emerged in the postwar period and was eventually rebranded as condensed-matter physics illuminates some major shifts in the late-20th-century physics community."`

Thanks Paul Pukite..very interesting refs..

Here is one Azimuth thread that is currently discussing the climate behaviors that may have topological origins
