Another high-quality presentation about climate change in Houston, by the venerable Dr. Ronald L. Sass, Professor Emeritus Rice University. Like most academic treatments of the topics covered, only that known with high certainty is reported. There are far more uncertainties that science has not yet pinned down, but that empirical investigations of the past have shown to be worrisome, potentially catastrophic for coastal civilization within a human lifetime. The reader is left to other sources and to their own developing understanding of the immense complexities of rapid climate feedback interactions to imagine the meaning to Houston of the topic covered by Dr. Sass at the conference. Still, an excellent and authoritative place for Houston to begin!
