Setting the record straight on some of the most common misleading narratives and tactics to explore what future climate change battlegrounds might look like. We look at how fossil fuel interest groups use division as a distraction: either stoking fear that action to tackle climate change will hurt the poor, or attacking the messengers who raise the alarm. And we take you back to the start of 2021, when blackouts in Texas which killed hundreds were misleadingly blamed on wind turbines. The idea that renewables, like solar or wind power, are dangerously unreliable has been a common theme. What’s the truth behind the claim? And how does bad information surface after extreme weather events and times of climate crisis?

At the grand old age of 20, Wikipedia remains one of the world’s most popular websites. The fact that anyone with internet access can edit its pages is a key part of its success. But the website’s openness to the public is also the reason why it has become an unlikely battleground on global warming. Despite the overwhelming body of science proving climate change is real and man-made, deniers are still active on Wikipedia. Whether it is by editing climate pages or spreading conspiracy theories, they have for a long time tried to reframe our understanding of climate change. But a small group of dedicated volunteers is determined to keep them at bay, setting the record straight on the facts and the science behind global warming. In this episode of the Denial Files, we set out to meet some of those volunteers and investigate how vulnerable Wikipedia remains to climate denial today.

Covid conspiracists are now shifting focus to climate change. An online movement infected with extreme pandemic conspiracies is looking for new territory as debates over lockdowns and vaccines subside in many richer countries. We hear from Matthew in New Zealand. His family is really worried about the future of the planet, but he’s involved in groups where people believe that climate change is a “hoax” designed to limit our personal freedoms. They’ve swapped in “climate science” for “Covid” in their viral online conspiracy theories. Matthew found himself drawn into this conspiratorial belief system through a global anti-lockdown movement called The White Rose. The White Rose has local channels around the world, and researchers at the Institute for Strategic Dialogue think tank say the local group dedicated to New Zealand is where climate change conspiracies have taken off the most. Researchers point out that a ready-made network of people who have fallen for misleading claims about global Covid-19 plots has created a receptive audience for lies about climate change. And in Germany, we hear about how members of the Covid-denying Querdenken group travelled to a region devastated by floods, intimidating helpers and spreading confusion about what had taken place. Locals were mystified and insulted, but it was another sign that climate change has become the new front line in the fight against online misinformation.

Brazil has pledged to end deforestation within a decade in a pledge signed by more than 100 nations at the COP26 climate summit. But do Brazilian leaders really believe in fighting climate change? Inside the country, climate change disinformation is thriving, while good and credible information is being undermined, even by the country’s own president. Influential voices with connections to the agriculture industry are spreading baseless conspiracy theories that man-made climate change is a hoax, invented by foreigners to hold the country’s economy back. Scientists at one of the government’s own agencies were accused of being “bad Brazilians” by President Jair Bolsonaro, after they produced data which showed an alarming rate of deforestation in the Amazon. The row resulted in the sacking of the head of the agency, who now fears the government is in the grip of climate change denialism. However, President Bolsonaro insists he is stepping up protection of the environment and has warned other countries not to meddle in Brazil’s internal affairs. Is the Amazon, one of the most important regions in the world for fighting climate change, safe in his hands?

Is big oil trying to mislead the public about what it’s doing about climate change? Several US states are suing some of the world’s largest oil and gas companies, accusing them of “greenwashing”. They claim the fossil fuel industry is deceiving consumers about how much it’s actually doing to tackle climate change. Accusations which are strongly denied by the companies who may face having to make huge compensation payouts if they lose in court. At the heart of many of these cases are adverts which highlight how energy giants are supporting greener, more sustainable solutions, but do not mention their much greater investment in developing new oil and gas fields. Questions about this alleged deception have now entered the political arena with big oil’s top brass being invited to appear before the US Congress. So, why do these lawsuits matter so much? In this episode, we head to Massachusetts where one such case is playing out in the courts.
