A member of the Real Climate proponent collective.
He is a physicist who works as a senior scientist at the Norwegian Meteorological Institute. He earned a D.Phil in physics from Atmospheric, Oceanic and Planetary Physics at Oxford University (U.K.) Recent work has involved analysis, statistics, research on local/regional climate, and seasonal predictability, but past experience also include ocean dynamics/air-sea processes and cloud micro-physics. He is the author of Solar Activity and Earth's Climate (2002).
Debating Fred Singer
This is an excellent debate. RB appears at 3:32. Make sure you watch the third one in the series.
1. Key point: In the first few minutes of section 3 of this set of videos, Benestad use the hockey stick to make the point [at 1:00 precisely] that because current temperatures are higher that any over the last 1000 years, "they must be forced.". This is an example of what I call the AGW missing link argument.
He then goes onto deal with what the forcing could be, ultimately proving that CO2 is the only possible cause. This in essence is the key point in his argument that everything hinges on.
However: Keith Briffa on MWP: "For the record, I do believe that the proxy data do show unusually warm conditions in recent decades. I am not sure that this unusual warming is so clear in the summer responsive data. I believe that the recent warmth was probably matched about 1000 years ago. I do not believe that global mean annual temperatures have simply cooled progressively over thousands of years as Mike appears to and I contend that that there is strong evidence for major changes in climate over the Holocene (not Milankovich) that require explanation and that could represent part of the current or future background variability of our climate."
