    Bessel functions of the first kind are ubiquitous in the sciences and engineering in solutions to cylindrical problems including electrostatics, heat flow, and the Schrödinger equation. The roots of the Bessel functions are often quoted and calculated, but the maxima and minima for each Bessel function, used to match Neumann boundary conditions, have not had the same treatment. Here we compute 10000 extrema for the first 600 orders of the Bessel function J. To do this, we employ an adaptive root solver bounded by the roots of the Bessel function and solve to an accuracy of 10−19. We compare with the existing literature (to 30 orders and 5 maxima and minima) and the results match exactly. It is hoped that these data provide values needed for orthogonal function expansions and numerical expressions including the calculation of geometric correction factors in the measurement of resistivity of materials, as is done in the original paper using these data.

    The 27th Conference of the Parties (COP 27) to the United Nations Framework Conven­tion on Climate Change (UNFCCC) in Sharm el-Sheikh, Egypt, was marked by multiple crises and the shaken confidence of developing countries in the multilateral process. Nonetheless, an agreement was reached on the critical issue of loss and damage, even though many key aspects still need to be fleshed out. With regard to emission reductions, there is a credibility crisis that threatens to worsen, not only because political priorities have shifted following Russia's attack on Ukraine. In order to strengthen international climate cooperation in the coming years, it will be crucial to honour existing commitments, adhere to agreed processes, and show diplomatic tact in dealing with partner countries.
