We should be more scared of climate change destroying humanity than AI
Experts warn that the climate crisis is a far greater existential threat than AI, with extreme weather, food shortages and national security risks already unfolding worldwide. The article urges urgent action to address climate change before it triggers catastrophic outcomes.
When headlines scream of an AI apocalypse, it’s easy to overlook the far more immediate danger that is already unfolding across the globe: the climate crisis. While a handful of tech researchers have suggested that artificial intelligence could wipe out humanity within a decade, the evidence shows that rising temperatures are already driving famine, conflict and disease on a scale that threatens every nation.
AI fears versus climate reality
In early 2024, safety researcher Evan Hubinger of Anthropic tweeted that there is more than a 10 % chance that advanced AI could kill all humans within ten years. The comment sparked social‑media panic and calls for a global “kill switch” for AI systems. Yet the same urgency is not being applied to the climate emergency that has been documented for over a century. Extreme heat, floods, wildfires and droughts are now common across every continent, and the impacts are already measurable in human lives and economies.
Concrete climate disasters are everywhere
- England recorded 2,877 heat‑associated excess deaths in May and June 2026, nearly double the total for the previous summer.
- Wildfires have scorched vast areas of Europe and the United States, destroying homes and ecosystems.
- Massive floods in South Asia and Africa have displaced millions and triggered food shortages.
- Wildfires in the Amazon and Southeast Asia are releasing carbon that further accelerates warming.
These events are not speculative; they are happening now and are linked directly to rising global temperatures. The climate is already reshaping the world, and the consequences are far more tangible than the theoretical risks posed by large language models.
Experts call for a climate “endgame” plan
In 2022, a Cambridge‑led team led by Dr Luke Kemp published a paper urging the world to prepare for a “climate endgame.” The authors identified four major risks—famine, extreme weather, conflict and vector‑borne diseases—that could trigger cascading disasters. They warned that even modest warming could tip the planet into a state of mass extinction, echoing the patterns seen in past geological eras.
Dr Kemp noted that the knock‑on effects of climate change—financial crises, supply‑chain disruptions and new disease outbreaks—could undermine recovery from other catastrophes, including nuclear war. The research underscores that climate change is not a distant threat but a present danger that could accelerate other existential risks.
Governments and activists demand action
The UK’s National Emergency Briefing campaign has called for a wartime‑scale response to the climate crisis, including a live televised emergency briefing to galvanise public support. Over 100,000 signatures on the petition have already triggered a parliamentary debate. The campaign’s documentary, fronted by Chris Packham, is being screened nationwide to raise awareness.
Green Party leader Zack Polanski has urged the release of a full UK spy‑agency report that details how climate breakdown threatens national security. The report warns of crop failures, water scarcity, novel diseases, inflation, mass displacement and even armed conflict—all consequences of ecosystem collapse.
Adrian Ramsay, a Green Party MP, said in Parliament that “climate breakdown and nature security are the most immediate and severe national security threats facing our age.” He argued that food, water and health depend on stable ecosystems, and that ignoring the threat is tantamount to ignoring the most pressing risk to humanity.
What’s next?
While the world debates AI safety, the climate crisis demands immediate, coordinated action. Governments must adopt emergency frameworks, invest in resilient infrastructure, and enforce policies that curb emissions. The public, too, can influence outcomes by demanding transparency, supporting renewable energy, and reducing carbon footprints.
Ignoring the climate emergency in favour of speculative AI scenarios risks leaving humanity with no viable future. The stakes are clear: the planet’s warming trajectory is already reshaping societies, economies and ecosystems in ways that threaten survival on a global scale.
Why it matters
The climate crisis is already causing tangible harm worldwide, while AI risks remain largely theoretical. Addressing climate change is essential to prevent cascading disasters that could endanger humanity’s future.
Key points
- AI extinction fears are often overstated compared to the tangible climate crisis.
- Extreme weather events are already causing thousands of deaths and economic damage.
- Cambridge researchers warn that climate change could trigger famine, conflict, disease and even extinction.
- UK political movements are calling for emergency action and full disclosure of climate security risks.
- Immediate, coordinated policy responses are needed to mitigate climate‑driven catastrophes.
- Public engagement and transparency are critical to accelerate climate action.
Frequently asked questions
Why is climate change considered a greater threat than AI?
Climate change is causing measurable, immediate harm—extreme heat, floods, famine—affecting billions, whereas AI risks are speculative and lack concrete evidence of imminent harm.
What is the UK’s National Emergency Briefing campaign?
It is a movement urging the UK government to treat climate change as a wartime emergency, including live televised briefings and public petitions to trigger parliamentary debate.
What does the Cambridge research team propose?
They recommend preparing for a “climate endgame” by studying worst‑case scenarios, such as a 10 % loss of the global population, and addressing the four major risks: famine, extreme weather, conflict and disease.
