Sophie's Planet

Sophie’s Planet was almost finished four years ago. I had drafted and received comments on 47 chapters. I just needed to tighten those and write the last several chapters. But new climate data (i.e., observations) became available that allowed more in-depth investigation of ongoing climate change. We explored possible implications of that data in two papers (Global warming in the pipeline and Global warming has accelerated). Sorry that the papers were long, but wanted to look at the data from various angles, which is a common, effective, research approach.
Last week I put out my first article on Substack. You can sign up here:
That article included a link to several chapters of the draft of Sophie’s Planet. I’m now in the process of revising and tightening all chapters. I won’t send out most of these, but here I give the new version of the Preface and welcome criticisms.
