Sea-level Rise Predictions

Since the 1980s computer model projections of climate change have underestimated this event. With greater advances in our understanding of the greenhouse’s effect on environmental change we have been able to make what scientists believe to be more accurate projections. However, recent radar studies of Antarctic ice mentioned in this New York Times article show there are likely more factors we are not aware of.

In this case we learn that warming ocean waters have created a huge cavity beneath one of Antartica’s ice sheets. Since most of this sheet lies above the ocean, if and when it breaks off, it could raise sea-level by as much as two feet within a short period of time–threatening coastal cities and many islands across the world.

As many environmental scientists have proposed, climate change might reach thresholds (i.e., tipping points) where unanticipated sudden catastrophic events might occur.

I'm a retired medical sociologist from the University of Rochester. Climate change is one of the two great challenges facing humanity (the other is nuclear weapons). In writing about the impact of climate change I read reputable books and articles on the topic. So when I make statements about climate change you will see a link taking you to the scientific source(s) of the information I provide. As for my independently published photobooks, each has gone through several layers of editing and peer review for both readability and accuracy. This is not to say that everything I say is accurate. Even the New York Times makes mistakes. So, if you find something that is factually incorrect, let me know. I hope you find reading my blog a positive experience. If you do, please encourage your family and friends to have a look. You can find photos from my other photo work by clicking on the My SmugMug Gallery tab, above. Best wishes, -Steve
