Examining Hansen's prediction about the West Side Highway

What the science says...

Hansen was speculating on changes that might happen if CO2 doubled.

Climate Myth...

Hansen predicted the West Side Highway would be underwater

'What I can comment on is this prediction by Dr. Hansen: “The West Side Highway [which runs along the Hudson River] will be under water.” As you can clearly see in the Google Earth images, the West Side Highway remains dry and open. Sea level (at which the Hudson River at that point becomes) is not encroaching on the highway' (Anthony Watts)

James Hansen made his statement in response to a question by Bob Reiss, a journalist and author, in 1988.  He did not 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 article are different.  In The Coming Storm the question includes the conditions of doubled CO2 and 40 years, while the 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 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.

Comments 1 to 7:

  1. It will be interesting to see if the WUWT article will ever acknowledge the account published in 2001 in Bob Reiss's book, The Coming Storm, or acknowledges the answer given by Dr. Hansen could have been a speculation about doubled CO2 (560 ppm).
  2. Yes, they did
  3. DirtyDigger, that same link is included in the article above... and the text of the link itself claims that Hansen's prediction has already failed... which is impossible given that it was for a future event which might still occur.
  4. Photo of flooding along the Westside Highway during Hurricane Sandy.
  5. Here is another one: And I will remind here that Hansen was talking not only about ocean surge but also hight winds. He apparently meant a tropical hurricane in NY. "“The West Side Highway will be under water. And there will be tape across the windows across the street because of high winds". His prediction came true after 24, not 40 years!
  6. Curiously enough, here is the West Side Highway as of 10/30/2012: [Source] This is due to the "Sandy" storm surge, not a steady-state sea level rise. But both historically unprecedented - and with continued global warming, perhaps something to expect again...
  7. When I read the relevant comments on WUWT, I note how successfull his propaganda is.   That is, no one seems to notice (or maybe care) that Hansen had a contingency, that is, that CO2 must double.
