Green’s Zack Polanski claims ‘climate crisis is biggest threat to Britain since World War Two’ – as he appears with BBC’s Chris Packham who ‘fantasises’ about climate denial being a crime
Green Party leader Zack Polanski has described the climate crisis as the greatest threat facing Britain since the Second World War, making the claim during an appearance alongside BBC naturalist Chris Packham. The comments come as Polanski continues to position climate action as central to his leadership of the Greens, while Packham has separately drawn attention for saying he "fantasises" about climate change denial being made a criminal offence.
The pairing of the two figures has fuelled debate over the tone of climate campaigning in Britain, with critics likely to seize on Packham's remarks about criminalising denial as evidence of intolerance towards dissenting views, while supporters may see it as reflecting the urgency both men attach to the issue. Polanski, who leads the Green Party, has increasingly used high-profile media appearances to press the case for radical climate policy, framing the crisis in historic terms comparable to wartime emergency.
In short
- Polanski likens climate crisis to World War Two-level threat to Britain
- He appeared alongside BBC's Chris Packham to make the case
- Packham says he "fantasises" about climate denial becoming a crime
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Climate advocates argue that an existential crisis justifies mobilisation rhetoric comparable to wartime emergency and vigorous action against well-funded disinformation campaigns. They contend that when civilisational stakes are this high, shaping public discourse away from deliberate falsehoods is a legitimate and necessary response.
The case against
Critics argue that criminalising dissent or disagreement, however well-intentioned, breaches free expression fundamental to democracy. They contend that climate policy involves legitimate uncertainties deserving open debate, and that emergency rhetoric risks alienating the consensus-builders essential for action whilst creating dangerous precedent for suppressing inconvenient views.
Explained simply
The Green Party is a British political party that campaigns on environmental protection and climate policy. Its leader, Zack Polanski, speaks for the party and uses public appearances to set out its priorities.
Climate change refers to long-term shifts in temperatures and weather patterns, driven in part by human activities such as burning fossil fuels. Governments and campaigners disagree over how quickly to cut emissions and which measures are appropriate.
Chris Packham is a naturalist and television presenter known for speaking publicly about wildlife and environmental issues. His comments about making climate change denial a crime have raised questions about how campaigners should respond to disagreement.
