Analysis of "9 questions on rising seas"

Scientists’ Feedback


The article succeeds in conveying the main causes, aspects and impacts of rising sea levels. While it does contain a few incomplete scientific statements and facts that ought to be explored and expanded upon in more depth, the article accurately conveys the general scientific realities of the issue.

The present article requires correction because some facts are missing or misleading. I find the link between the 2-degree world and sea level rise weak. It is not clear what sea level rise will be avoided by limiting warming to 2 degrees. Personally, I am not satisfied with a +2 deg world because ice sheet melt won’t stop with that. I would rather support a return to conditions prevailing in the earlier part of the 20th century. Yes, that means we have to find ways to suck the CO2 back in, not just limit our emissions. What an exciting challenge!

Overall I found the article to be mostly accurate. There are some minor issues, but these are mostly issues of more detail, not of incorrect statements. I’m happy to see this level of reporting on CNN.


These comments are the overall opinion of scientists on the article, they are substantiated by their knowledge in the field and by the content of the analysis in the annotations on the article.

It is a relatively short article but it does capture the main details. It would strengthen in my opinion if the writers took care in mentioning the sources.

This article does a very good job at presenting the main aspects of sea level rise and how it will impact coastal regions. There are some incomplete statements (notably with regards to the notion that sea level scenarios presented are global averages), but they do not detract from the main message.

This article provides an accurate and fairly thorough discussion of the causes and impacts of global warming-caused sea level rise. It left out a lot of important details regarding local differences and the wide range in projections of future global average sea level rise.

The article is quite good and reasonably complete, it focuses very much on the changes in global mean sea level. The spatial differences in sea level change will be very large and thus play an important role, which is overlooked in the article

It seems to me this article presents the different aspects of the issue of sea-level rise rather accurately, given the short format.
