In recent global discussions, including at the United Nations General Assembly, climate change has once again become a focal point of debate. While some voices have questioned its validity, dismissing it as a "con job" or political construct, the reality remains firmly grounded in science and a clear scientific consensus has emerged —one that cannot be ignored.
Climate change a scientific consensus
The Intergovernmental Panel on Climate Change (IPCC), the world's most authoritative source on climate science, has repeatedly warned that exceeding 1.5°C of warming above pre-industrial levels will trigger severe and irreversible consequences for ecosystems and societies.
Dr. Maria Julia Trombetta, associate professor in politics and environment at the University of Nottingham Ningbo China, emphasizes that there is a scientific consensus on the seriousness of the threats posed by climate change and the political rhetoric will not impact that.
"The IPCC has clearly documented the seriousness of climate change,"she says. "Moreover, the consequences of climate change are already becoming evident, with the hottest years ever recorded, more frequent extreme weather events, the melting of glaciers, and unprecedented wildfires."
Professor Troels Skrydstrup from Aarhus University in Denmark adds that the evidence is all around us."We're seeing higher local temperatures, prolonged droughts, heavier rainfall, and stronger storms. These are not isolated events — they are patterns consistent with climate models."
He warns against complacency: "Humans adapt gradually, so year-to-year changes may seem minor. But over decades, these shifts accumulate. Without sustained global cooperation, the long-term consequences will be catastrophic."
The science is settled. The challenge now no longer lies in proving climate change exists, but in responding to it with urgency and equity.
Fallout of dismissing climate change as a hoax
As Denis Simon, a visiting professor from Duke University in the U.S., explains, labeling climate change a "con job" undermines multilateral institutions like the UN, IPCC, and the UN Framework Convention on Climate Change, which rely on shared recognition that climate change is real, human-caused, and urgent.
"This language provides cover for rolling back environmental regulations, subsidizing fossil fuels, weakening clean energy mandates, and retreating from international climate commitments," Simon said. "It turns denial into policy."
The implications extend far beyond domestic politics. When major emitters like the United States disengage from climate pacts, it lowers the ceiling of what is politically possible globally. Ambition wanes, funding dries up, and trust erodes, especially among vulnerable developing nations that depend on financial and technological support for adaptation and mitigation.
"The 'green scam' narrative isn't harmless skepticism,"Simon warns. "It actively obstructs progress and delays action at a time when every fraction of a degree matters."
By rejecting science, such rhetoric doesn't just mislead — it endangers lives, economies, and the planet's future.
China leading the green revolution
While some have retreated into denial, others are building solutions. Nowhere is more visible than in China, where wind power is expanding at an unprecedented scale.
Dr. Francesco Faiola, an Italian scientist at the Chinese Academy of Sciences, recalls a telling moment on a high-speed train from Beijing to Jinan in east China: endless rows of wind turbines spinning across open fields under a clear sky. "You don't need complex arguments to counter misinformation," he says. "Just look at the facts. China's wind energy boom is undeniable proof of transformation."
From vast wind farms in the Gobi Desert to offshore installations along the eastern coast, China is rapidly deploying renewable infrastructure. According to the National Energy Administration, in 2024 alone, China added 79.82 million kilowatts of new wind capacity — a six percent year-on-year increase. By the end of 2024, total grid-connected wind capacity reached 521 million kilowatts, up 18 percent annually, with 480 million kW from onshore and 41.27 million kW from offshore sources.
"This growth reflects both national commitment and industrial maturity," Faiola observes. "China is not only the world's largest manufacturer of wind turbines, it's also their biggest user. Thousands of engineers, massive investment plans, and integrated supply chains are driving this transition."
Far from being a passive observer, China is actively reshaping its energy system and in doing so, helping to decarbonize global manufacturing.
Global cooperation for a livable future
The path forward, experts agree, must be collaborative. No single country can solve the climate crisis alone, but leadership, like China's rapid deployment of green technologies, can inspire and enable broader action.
Skrydstrup highlights the significance of China's efforts: "Given China's massive energy demands and central role in global production, its shift toward green energy is a major step forward in combating climate change. This is the direction (in which) the world needs to go, not backward into denial."
Faiola stresses that the green transition is not a burden, but an opportunity: "It offers economic growth, energy security, and environmental protection. As scientists, our duty is to present evidence and foster rational dialogue." Despite political setbacks, a momentum is building worldwide. Renewable energy costs are falling, technologies are improving, and public awareness is rising. The message is consistent: the future must be sustainable.
