The world is sleepwalking toward a climate catastrophe, scientists warn, as decades of rising greenhouse gas emissions push the planet toward weather events of unprecedented scale.
What once seemed like distant speculation is now a matter of urgent scientific consensus: a catastrophic climate event is no longer a question of possibility, but of timing, The Independent reports.
"The risk is that people just think you are exaggerating," said Daniel Swain, a climate scientist with the California Institute for Water Resources.
"It's the 'Boy Who Cried Wolf' problem. Sometimes wolves are real. If it's outside the door, wouldn't you want to know?"
Global temperatures in 2025 stand 1.44C above pre-industrial levels, a rise scientists attribute overwhelmingly to fossil fuel emissions.
That warming is already reshaping weather in measurable, damaging ways. Australia's "Black Summer" bushfires scorched over 19 million hectares. Flooding submerged a third of Pakistan. Hurricanes Milton and Helene devastated parts of the United States. Los Angeles saw entire neighbourhoods consumed by wildfire.
And it is going to get worse.
Sarah Perkins-Kirkpatrick of the Australian National University says that even if the world achieved net zero emissions immediately, extreme weather events would continue for centuries.
Carbon dioxide persists in the atmosphere for hundreds of years. "It's the issue of the frog in the boiling water," she said. "If we get used to bracing ourselves, are we going to notice?"
Scientists cannot say exactly when a catastrophic event will strike -- only that the conditions are worsening.
Sonia Seneviratne of the Intergovernmental Panel on Climate Change (IPCC) compares the risk to smoking and lung cancer: uncertainty about the outcome does not remove the obligation to warn.
"If such an event happened, I could already see the criticism of people saying, 'Climate scientists didn't tell us,'" she said. "But we did."
The concern is not hypothetical.
Between 2023 and 2025, 84 percent of the world's coral reefs suffered severe heat stress.
The Amazon rainforest -- a vast carbon store critical to regulating global climate -- is losing ground to drought, fire, and deforestation.
Scientists are no longer asking whether it will shift from absorbing carbon to releasing it, only when.
This year's El Niño cycle is forecast to be the strongest on record, threatening to push temperatures still higher.
Where science demands urgency, politics has largely delivered denial.
US President Donald Trump has called climate change "the greatest con job ever."
The United States, the largest cumulative emitter of greenhouse gases in history, has retreated from climate action precisely as the risks are accelerating.
Seismologist Lucy Jones, who helped develop Los Angeles's earthquake preparedness programme, argues that people will act on risk -- but only if they believe it is real and that solutions are possible.
Without that, denial takes hold. "Climate denial is one way of coping," she said. "People rationalise by thinking, 'I won't believe it's true, so I'll feel safer.'"
No country is genuinely prepared for a large-scale climate disaster.
More than half of all greenhouse gases ever produced have been released in just the past 50 years.
The physics are unambiguous: the more heat trapped, the more volatile the system becomes.
A catastrophic event may be decades away.
It may be sooner. What scientists are no longer willing to say is that it is unlikely.
