One climate myth found on the internet, propagated by Anthony Watts, is that James Hansen erroneously predicted the West Side Highway would be underwater by 2008. James Hansen made his statement in response to a question by Bob Reiss, a journalist and author, in 1988. A close examination of the interview reveals Hansen did not, in fact, predict that the West Side Highway would be underwater in 20 years. Bob Reiss reports the conversation as follows:
"When I interviewed James Hansen I asked him to speculate on what the view outside his office window could look like in 40 years with doubled CO2. I'd been trying to think of a way to discuss the greenhouse effect in a way that would make sense to average readers. I wasn't asking for hard scientific studies. It wasn't an academic interview. It was a discussion with a kind and thoughtful man who answered the question. You can find the description in two of my books, most recently The Coming Storm."
James Hansen reports the conversation as follows:
"Reiss asked me to speculate on changes that might happen in New York City in 40 years assuming CO2 doubled in amount."
The book The Coming Storm and the salon.com article are different. In The Coming Storm the question includes the conditions of doubled CO2 and 40 years, while the salon.com article which is quoted by skeptics does not mention doubled CO2, and involves only 20 years.
To understand the discrepancy between these two published accounts, it helps to look at the timeline of events. The original conversation was in 1988. Ten years later, referring to his notes, Bob Reiss recounted the conversation in his book The Coming Storm. James Hansen confirmed the conversation and said he would not change a thing he said. After the book was published, Bob Reiss was talking to a journalist at salon.com about it. As he puts it,
"although the book text is correct, in remembering our original conversation, during a casual phone interview with a Salon magazine reporter in 2001 I was off in years.”
We can check back in 2028, the 40 year mark, and also when and if we reach 560 ppm CO2 (a doubling from pre-industrial levels). In the meantime, we can stop using this conversation from 1988 as a reason to be skeptical about the human origins of global warming.
