Sophies 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 Sophies Planet. Im now in the process of revising and tightening all chapters. I wont send out most of these, but
here I give the new version of the Preface and welcome criticisms.
