His outspoken views led France 2 to take him off the air starting this Monday. "I received a letter telling me not to come. I'm in shock," he told RTL radio. "This is a direct extension of what I say in my book, namely that any contrary views must be eliminated."
The book has been released at a particularly sensitive moment as Paris is due to host a crucial UN climate change conference in December.
According to Mr Verdier, top climate scientists, who often rely on state funding, have been “manipulated and politicised”.
He specifically challenges the work of the Intergovernmental Panel on Climate Change, or IPCC, saying they “blatantly erased” data that went against their overall conclusions, and casts doubt on the accuracy of their climate models.
The IPCC has said that temperatures could rise by up to 4.8°C if no action is taken to reduce carbon emissions.
Mr Verdier writes: “We are undoubtedly on a plateau in terms of warming and the cyclical variability of the climate doesn’t not allow us to envisage if the natural rhythm will tomorrow lead us towards a fall, a stagnation or a rise (in temperature).”
The 330-page book also controversially contains a chapter on the “positive results” of climate change in France, one of the countries predicted to be the least affected by rising temperatures. “It’s politically incorrect and taboo to vaunt the merits of climate change because there are some,” he writes, citing warmer weather attracting tourists, lower death rates and electricity bills in mild winters, and better wine and champagne vintages.
Asked whether he had permission from his employer to release the book, he said: “I don’t think management liked it, let’s be honest.”
"I put myself via this investigation on the path of COP 21, which is a bulldozer, and we can see the results."
The book was criticised by French newspaper Le Monde as full of “errors”. “The models used to predict the average rise in temperatures on the surface of the globe have proved to be rather reliable, with the gap between observations and predictions quite small,” it countered.
Mr Verdier told France 5: “Making these revelations in the book, which I absolutely have the right to do, can pose problems for my employer given that the government (which funds France 2) is organising COP [the climate change conference]. In fact as soon as you a slightly different discourse on this subject, you are branded a climate sceptic.”
He said he decided to write the book in June 2014 when Laurent Fabius, the French foreign minister, summoned the country’s main weather presenters and urged them to mention “climate chaos” in their forecasts.
“I was horrified by this discourse,” Mr Verdier told Les Inrockuptibles magazine. Eight days later, Mr Fabius appeared on the front cover of a magazine posing as a weatherman above the headline: “500 days to save the planet.”
Mr Verdier said: “If a minister decides he is Mr Weatherman, then Mr Weatherman can also express himself on the subject in a lucid manner.
“What’s shameful is this pressure placed on us to say that if we don’t hurry, it’ll be the apocalypse,” he added, saying that “climate diplomacy” means leaders are seeking to force changes to suit their own political timetables.
According to L’Express magazine, unions at France Television called for Mr Verdier to be fired, but that Delphine Ernotte, the broadcaster’s chief executive, initially said he should be allowed to stay “in the name of freedom of expression”.
