Andrew W. Montford is a English writer, editor, chartered accountant, and the voice behind climate change skeptic blog Bishop Hill. He is also the author of The Hockey Stick Illusion  (2010). He currently lives in Scotland.

Montford set up the company Anglosphere in 2004 which provides editing services to the publishing industry and business.

Montford was named the Deputy Director of the Global Warming Policy Foundation in 2017. [12]

Stance on Climate Change

“I believe that CO2, other things being equal, will make the planet warmer. The six million dollar question is how much warmer. I'm less of a sceptic than people think. My gut feeling is still sceptical but I don't believe it's beyond the realms of possibility that the AGW hypothesis might be correct. It's more the case that we don't know and I haven't seen anything credible to persuade me there's a problem.” [1]

Key Quotes

“… of course mankind has always affected the climate. If I had my time over again, I would have made this point more clearly. I don't think you can get away from the radiative physics arguments for AGW. It seems likely to me that it has some effect, but as I tried to make clear in my 10 secs, we just don't know how big.” [2]

“The CRU disclosures demonstrate that the peer review process can be subverted by a small but influential group of scientists.” [3]

Key Deeds

November 23, 2017

After the GWPF published a book by Bernie Lewin titled “Searching for the Catastrophe Signal: The Origins of The Intergovernmental Panel on Climate Change,” Montford interviewed the book's author in a GWPF video (see below). [14], [15]

“It was only when the IPCC was threatened with alienation from the climate treaty process that it suddenly concluded “a discernible human influence on global climate,”  the GWPF press release reads. [16]

November 25-26, 2011

Montford appeared at EIKE's International Climate and Energy Conference in Munich, Germany. His speech was on “Climategate” and the Hockey Stick graph. [4]

The European Institute for Climate and Energy is a German climate skeptic organization with possible connections to the Committee for Constructive Tomorrow (CFACT).

September, 2010

Montford was commissioned by the Global Warming Policy Foundation (GWPF) to write an inquiry into the “Climategate” e-mails. He was compensated £3000 for his services, and GWPF released the results in September, 2010. [5], [6]

Three British enquiries, one by the House of Commons Science and Technology Committee, one an independent panel chaired by Lord Oxburgh, and an independent review led by Sir Muir Russell, had all exonerated CRU scientists from any misconduct or fraud before GWPF insisted on the additional effort.

According to Montford's own report, the other three enquiries were “rushed, cursory and largely unpersuasive.” He also criticizes the enquiries' lack of climate change skeptics on their panels, despite the fact that at least one known climate change skeptic, Graham Stringer, was present.

Montford could not be ignorant of this fact, as he recorded a conversation with Stringer on his blog, who he described as “the sole dissenter from the majority opinion represented by the report.” [7]

The GWPF also submitted a Memorandum by Nigel Lawson and Benny Peiser, while Andrew Montford submitted one of his own.

March, 2010

Montford released The Hockey Stick Illusion, published by Stacey International.

The book received mixed reviews. RealClimate concluded that “the real goal of those whose story Montford tells is not to understand past climate, it’s to destroy the hockey stick by any means necessary.” [8]

The Guardian also examined Montford's book and found numerous “glaring inaccuracies” that would be cause “to treat with some scepticism Montford's assessment of the validity of the inquiries into the hacked email messages.” [9]

Alastair McIntosh, writing for the Scottish Review of Books, concluded that “Montford’s analysis might cut the mustard with tabloid intellectuals but not with most scientists. The Hockey Stick Illusion might serve a psychological need in those who can't face their own complicity in climate change, but at the end of the day it's exactly what it says on the box: a write-up of somebody else’s blog.” [10]

According to a review by Geoscientist, “Montford's book presents McIntyre's case, complete with speculations about his opponents' motives, and gives little space to the detailed rebuttals provided by Mann and his co-authors. Indeed Montford admits in his Preface that the book grew out of a summary of postings on McIntyre’s blog 'Climate Audit'. This explains the bias in his story.” [11]

The book received positive reviews from sources including Matt Ridley in The Spectator and Christopher Booker in The Telegraph.

September, 2006

Andrew Montford began posting at his blog Bishop Hill.

While the blog first focused on British politics, it later devoted a large portion of coverage to “Climategate,” and Montford has since called his site “one of the main websites for global warming sceptics in the UK.” [3]

Montford said that his interest in the issue surrounding the “Hockey Stick” graph was piqued when he came across Climate Audit, a website run by Steve McIntyre  — a climate change skeptic and past mining-industry executive. [1]



Andrew Montford has never published an article in a peer-reviewed journal.

His most notable publication has been his 2010 book The Hockey Stick Illusion, published by Stacey International.
