Debates regarding the Maya collapse never end and in recent years various versions of the “drought” hypothesis have dominated (I tend to criticize them on various grounds). A new study on the distribution of obsidian at Classic and Postclassic sites has brought back an old collapse scenario to life. Changing trade networks led to the collapse in this study. Some details are new but not the idea itself. Read more about it in Antiquity. I guess the debate will continue.
