“It doesn’t have to be dystopian!” Rethinking migration as a solution in the face of climate change

From floods to (heat) waves: where do we go?

Migrants are often portrayed using dehumanizing metaphors such as "floods", "waves", and "flows", exaggerating the sense of threat and crisis associated with large-scale migration in mainstream media. Ironically, these metaphors also highlight the real challenges of climate change-induced migration that we will undoubtedly face in the near future. The recent COP28 UN climate talks in Dubai underscored concerning predictions for our future, making it clear that discussions about migration will increasingly be interlinked with the occurrence of weather extremes and natural disasters.

Recent evidence suggests that keeping global warming below 1.5°C -a key target of the 2015 Paris Agreement signed by 195 nations—may no longer be achievable. Climate scientists warn that there is now a 50% chance we will exceed this temperature limit by the mid-2030s, if not sooner. Exceeding the 1.5°C threshold for multiple decades, as highlighted in the IPCC special report, would have severe consequences, including more extremely hot days, accelerated glacier melt, and rising sea levels. The expected heatwaves will not only have dire effects on our planet but also on humanity, leading to famines, and droughts. Several meters of sea-level rise would threaten the land, livelihoods, and cultural heritage of coastal communities, inevitably resulting in large-scale migration.

Debunking myths and navigating uncertainty

Following the discourse on climate change-induced migration depicted in the media, our future does sound dystopian. Can we effectively manage the millions of people who will have to flee, or will we inevitably fall into societal chaos and conflict – as Hobbes described with “bellum omnium contra omnes”? How can northern countries, which are expected to be most affected by mass migration, prepare for this potential influx? Interestingly, political discourse and scientific findings on climate change-induced migration differ significantly. The notion that large numbers of people will flee from the Global South to the Global North due to climate change is not supported by current scientific evidence. Nonetheless, the myth of clear-cut push and pull factors in migration persists in political discourse of migration which instills fear among readers living in the Global North. As highlighted in the recently published paper in the Nature Climate Journal, this narrative can influence policy responses, potentially leading to increased calls for border control and securitization measures which overshadow opportunities for sustainable solutions.

A clear illustration of this issue is for instance the recent debate over the migration and security decree introduced by Giorgia Meloni which has been warmly welcomed by Matteo Salvini with the words: “less crime and violence, more control and security: let’s go.” By prioritizing faster deportations of so-called "dangerous and illegal migrants" and focusing on new security measures to halt migration, migrants are treated as a security matter instead of prioritizing humanitarian aid. To shed more light on this ongoing discussion, several scientists have started actively arguing against this oversimplified theory, emphasizing that migration is driven by a complex mix of socio-economic, political, and cultural factors, not solely by climate change.

While climate change does impact migration, pinpointing its exact impact remains challenging. When discussing predictions, it is essential to acknowledge the inherent uncertainties involved before we jump to alarming conclusions. Sudden climate disasters can indeed displace large populations; however, climate change experts emphasize that predicting future displacement figures is complex. Instead of trying to find exact numbers we cannot possibly predict, we should much rather focus on data to model trends that anticipate the vulnerability and adaptation capacities among affected communities.

Migration as a tool to help us build stronger communities

Although the idea of hundreds of people losing their homes still is – rightfully so – deeply unsettling, Gaia Vince presents a hopeful perspective on how humanity can navigate habitat loss. In her latest book, "Nomad Century," she explores migration as a key to success that has shaped our species' resilience over different decades. Vince draws parallels from global movements, like rural-to-urban migration, illustrating how migrants can successfully integrate and thrive within new communities. She also challenges the prevailing narrative of political hostility towards migrants, urging for an approach that is more based on scientific evidence and rooted in empathy instead of border control.

In dealing with large-scale displacement, she emphasizes, that we need to collectively reframe how we envision our future amidst environmental changes. We cannot expect these changes to be smooth and predictable but at the same time, this does not mean that our situation is hopeless. Large-scale migration can work. This can be shown if we look at how the EU successfully managed the 2022 influx of Ukrainian refugees suddenly losing their homes. Also, when looking at China, where around 400 million people migrated to cities, we can see, if needed, that we can indeed adapt quickly.

In Vince’s vision, adapting to climate-induced migration is not just about survival – it is also about embracing opportunities to build stronger and more resilient communities. Her insights challenge us to rethink migration not as a burden to society but rather as a pathway to collective growth. Navigating the complexities of climate change-induced migration calls for a balanced approach that moves beyond alarmist narratives. By promoting informed dialogue and evidence-based policies, societies can better prepare for the future impacts of climate change. This also implies accepting that we will have to adapt while also remembering that people have always been on the move throughout history.

Migration is not something that we will be able to change or prevent from happening. We should start planning and preparing for this upheaval as soon as possible – despite being afraid of the challenges ahead. At the same time, we need to fundamentally challenge our perspective on what we are truly afraid of. Instead of viewing migration as the primary issue, we should critically examine the underlying factors that fuel our fears. This requires a shift in focus from seeing migration as a threat to understanding the broader social, economic, environmental and political dynamics at play that leave people with no choice but to leave their home countries.

By addressing these root causes, we can develop more compassionate and effective responses to migration, recognizing it as a complex humanitarian issue rather than a simple security concern.
