In the past few years, climate change has emerged as one of the leading drivers of migration. Shifting weather patterns, together with the growing severity and frequency of extreme weather events, have affected millions of people around the world, posing a significant threat to their lives and livelihoods.
In March, the Intergovernmental Panel on Climate Change published its sixth assessment report, showing that for every additional 1°C rise in global temperatures, the risk of involuntary displacement due to flooding is expected to increase by about 50 percent.
In sub-Saharan Africa, South Asia and Latin America, slow-onset climate disasters such as water stress, crop failure and rising sea levels could displace 31 million to 72 million people by 2050 under a low-warming scenario. In a high-warming scenario, the number of displaced people could surge to 90 million to 143 million.
In sub-Saharan Africa, flood-related displacement could rise by 200 to 600 percent by the 2070s, depending on the rate of population growth and anticipated temperature increases ranging from 1.6°C to 2.6°C.
While the Global South is disproportionally affected by the catastrophic effects of climate change, no part of the world is immune. The climate crisis is going to have far-reaching implications for global stability, security and sustainable development, affecting not only migrants’ countries of origin, but also transit and destination countries.
The COP27 Presidency and the International Organization for Migration (IOM) are committed to addressing the challenge of climate-induced migration with the goal of fostering a more just and equitable world. Over the past year, we have collaborated with governments, civil society organizations, other UN agencies and several stakeholders to develop and promote sustainable approaches to climate-related mobility, including displacement.
To reduce the adverse effects of climate change that compel migrants to leave their countries of origin, we advocate the full implementation of the Global Compact for Migration. With the support of the IOM, the COP27 Presidency has highlighted Egyptian programs such as the Climate Responses for Sustaining Peace and the Decent Life Initiative as models that could be replicated worldwide.
Taken together, these initiatives offer a road map for sustainable development, enabling governments to improve living standards and maintain peace in the face of climate-related threats. We have promoted these initiatives at formal and informal forums, including the Global Forum on Migration and Development.
For sure, there is still much work to be done. To address the urgent threat posed by climate change, the international community must support adaptation efforts, particularly in the Global South. Strengthening resilience is crucial to empowering populations to make informed decisions about whether to relocate or remain where they are.
However, achieving this requires immediate and substantial financing for adaptation initiatives, including the much-anticipated Loss and Damage Fund for developing countries announced at COP27 in Sharm el-Sheikh. Other crucial steps include ensuring the complementarity and accessibility of climate funding instruments and incorporating human mobility considerations into climate negotiations.
Climate-related migration and displacement need to be focused on while concrete solutions that promote the safety and well-being of affected communities and individuals are developed. This involves supporting the implementation of effective initiatives and the integration of migrants’ perspectives and experiences into decision-making processes.
Climate change often exacerbates existing challenges and vulnerabilities, forcing communities to confront compounding crises. Therefore, it is crucial to recognize and address these underlying factors, including conflict, poverty and inequality. To this end, a holistic approach that promotes peace and security, reduces poverty and inequality, and fosters sustainable development must be adopted.
Displacement is a complex and daunting challenge that requires a comprehensive, coordinated and forward-looking response. Enhanced international cooperation could significantly improve the lives and livelihoods of those displaced by climate disasters and produce sustainable solutions that enable them to rebuild and contribute to their communities’ development. This approach is not only the right thing to do; it is also a crucial step toward building a more peaceful, just and sustainable future for everyone.
The stakes of the climate crisis are, or should be, obvious. The Mediterranean region, in particular, is no stranger to devastating environmental changes, as historical evidence suggests that extreme weather events might have triggered mass displacement and led to the downfall of great civilizations during what is now known as the Late Bronze Age Collapse.
To address climate-related displacement effectively, humanity must first understand and acknowledge the scale and complexity of the challenge. Only then will we recognize the need to engage all relevant stakeholders to develop proactive and sustainable solutions, avert the catastrophic effects of climate change and build a world that is prosperous and just.

US President Donald Trump and Chinese President Xi Jinping (習近平) were born under the sign of Gemini. Geminis are known for their intelligence, creativity, adaptability and flexibility. It is unlikely, then, that the trade conflict between the US and China would escalate into a catastrophic collision. It is more probable that both sides would seek a way to de-escalate, paving the way for a Trump-Xi summit that allows the global economy some breathing room. Practically speaking, China and the US have vulnerabilities, and a prolonged trade war would be damaging for both. In the US, the electoral system means that public opinion
In their recent op-ed “Trump Should Rein In Taiwan” in Foreign Policy magazine, Christopher Chivvis and Stephen Wertheim argued that the US should pressure President William Lai (賴清德) to “tone it down” to de-escalate tensions in the Taiwan Strait — as if Taiwan’s words are more of a threat to peace than Beijing’s actions. It is an old argument dressed up in new concern: that Washington must rein in Taipei to avoid war. However, this narrative gets it backward. Taiwan is not the problem; China is. Calls for a so-called “grand bargain” with Beijing — where the US pressures Taiwan into concessions
The term “assassin’s mace” originates from Chinese folklore, describing a concealed weapon used by a weaker hero to defeat a stronger adversary with an unexpected strike. In more general military parlance, the concept refers to an asymmetric capability that targets a critical vulnerability of an adversary. China has found its modern equivalent of the assassin’s mace with its high-altitude electromagnetic pulse (HEMP) weapons, which are nuclear warheads detonated at a high altitude, emitting intense electromagnetic radiation capable of disabling and destroying electronics. An assassin’s mace weapon possesses two essential characteristics: strategic surprise and the ability to neutralize a core dependency.
Chinese President and Chinese Communist Party (CCP) Chairman Xi Jinping (習近平) said in a politburo speech late last month that his party must protect the “bottom line” to prevent systemic threats. The tone of his address was grave, revealing deep anxieties about China’s current state of affairs. Essentially, what he worries most about is systemic threats to China’s normal development as a country. The US-China trade war has turned white hot: China’s export orders have plummeted, Chinese firms and enterprises are shutting up shop, and local debt risks are mounting daily, causing China’s economy to flag externally and hemorrhage internally. China’s
