US President Donald Trump rose to power partly by positioning himself as a foil to global elites. But last week, he attended the World Economic Forum (WEF) – the quintessential gathering of the world’s wealthiest and most powerful people – in Davos as the star guest. With the largest-ever US delegation in tow, Trump took his aggressive protectionism and transactional diplomacy to the global stage, shifting the debate and, in the process, increasing the risk of irreversible changes to the Earth system.
Instead of discussing issues such as fair taxation, sustainability, social justice, and the energy transition, as delegates have done in the past, they kowtowed to Trump. But Trump’s remarks at Davos should erase any remaining doubt that normalizing his extreme policies and strident positions only encourages him to double down on the geopolitical chaos and uncertainty he is causing. In the last month alone, Trump has withdrawn the US from 66 international organizations, including two of the world’s most important and oldest climate institutions – the 34-year-old UN Framework Convention on Climate Change (UNFCCC), which serves as the primary forum for climate negotiations, and the UN’s 38-year-old Intergovernmental Panel on Climate Change, which leads the science related to climate change. And just days before his trip to Davos, Trump stunned European leaders by threatening to impose punitive tariffs on allies that oppose his plan to seize Greenland from Denmark.
After more than a year of such wanton destruction and excessive use of unilateral measures to advance his “America First” agenda, trust – the lifeblood of multilateralism – has eroded, raising the risk of fragmentation and fueling instability. To mitigate these effects, sustain global growth, and promote shared prosperity, the WEF chose “A Spirit of Dialogue” as the theme for this year’s meeting. It may be one of the best-attended yet, with more than 3,000 delegates from over 130 countries, including 64 heads of state and government.
Dialogue, of course, is essential to resolve disputes, prevent conflict escalation – especially in our great-power-rivalry world of heightening geopolitical tensions – and prepare for risks. According to the WEF’s pre-Davos survey, the most severe risks over the next decade all relate to the climate emergency. But, to secure Trump’s participation, the WEF agreed to avoid “woke” topics, including the energy transition and climate change. So much for a spirit of dialogue.
The agenda instead focused on, among other things, improving cooperation in a more contested world, unlocking new sources of growth, investing in people, responsibly deploying innovation at scale, and building prosperity within planetary boundaries. Technology – particularly how AI, quantum computing, and next-generation biotech and energy systems can drive economic and societal transformation – was a prominent theme.
The silence on climate change is as cynical as it is unsurprising. One of Trump’s first acts in his second term was to withdraw the US from the Paris climate agreement. His administration later launched a major campaign to reverse US climate policy and expand fossil-fuel production. This has included halting the construction of offshore wind farms, slashing funding for renewable-energy projects, and working to repeal federal limits on greenhouse-gas emissions from power plants and vehicles.
Following Trump’s “drill, baby, drill” mantra, the administration has declared a “national energy emergency” and authorized the expansion of domestic fossil-fuel production. This policy could reverse progress in the transition to renewable energy, which contributed about one-third of global electricity generation in 2024. It also brings the world closer to a climate catastrophe, especially after scientists revealed earlier this month that the goal of limiting global warming to 1.5°C is now on track to be breached by 2030, more than a decade earlier than expected at the time of the 2015 Paris Agreement.
As the world’s largest historical and current emitter, the US economy’s continued reliance on fossil fuels has repercussions for everyone else. It will cause trillions of dollars in damage, disproportionately affecting poorer countries, and could push global warming above the 1.5°C target set by the Paris climate agreement. Crossing this threshold significantly increases the risk of irreversible changes to Earth systems; once climate tipping points are passed, self-reinforcing processes are activated that cannot be reversed, even if temperatures later decline.
One such tipping point is the collapse of the West Antarctic Ice Sheet, which would eventually raise global sea levels by around 13 feet. Such a drastic rise would permanently alter coastlines and threaten low-lying communities and island countries. Similarly, exceeding the 1.5°C goal accelerates permafrost thaw, releasing large amounts of carbon dioxide and methane into the atmosphere – a process that reinforces global warming and cannot be reversed.
Ecosystems also face irreversible losses if the planet exceeds 1.5°C of warming. Coral reefs are projected to decline by 70-90% at that temperature, while the Amazon rainforest, one of the world’s largest carbon sinks, risks becoming a carbon source, undermining natural mitigation efforts and further accelerating climate change. These changes could also have profound social consequences. Sea-level rise, for example, may wipe out coastal settlements, agricultural land, and freshwater resources, displacing communities and erasing cultural heritage.
Perhaps most importantly, surpassing 1.5°C locks future generations into managing a planet with higher climate risks and fewer adaptation options. More than diversifying energy sources, continuing the energy transition is essential for humanity’s survival; ignoring this reality to appease Trump and humor his oil obsession is a dangerous game with global and intergenerational consequences.
As the window to act on climate change narrows and the global order continues to fragment, dialogue must foster cooperation, strengthen collective problem-solving, and emphasize equity and justice. Decisions on emissions reductions, adaptation, and climate finance inherently raise questions of responsibility, fairness, and burden-sharing between countries and within societies. But the WEF has chosen convenience over security and long-term sustainability by allowing Trump to set the terms of the debate.
