For years, the foreign policy community has treated climate change as a "threat multiplier" - a slow-moving force that would eventually sharpen existing fault lines in fragile states. A recent Premise survey conducted across Colombia and the Philippines suggests that future has arrived. Across both countries, extreme weather is no longer a distant risk factored into long-range planning documents; it is a lived, monthly reality that is already reshaping how people think about water, health, and whether to stay in their homes at all.

A recent household survey of 1,368 respondents across the two countries, nations chosen because they sit near the top of global climate vulnerability indices, yet face very different exposure profiles, offers a granular look at how climate stress is translating into the kind of instability that foreign relations, development, and security practitioners are paid to worry about.

Two Countries, Two Very Different Shocks

The headline finding is a stark asymmetry. In the Philippines, 58% of households report being personally affected by an extreme weather event in the past year, driven largely by the country's exposure to powerful typhoons. In Colombia, that figure is 20% — still significant, but reflecting a pattern of more regionally concentrated flooding and landslides rather than nationwide storm exposure.

Where impact does occur, the damage is concrete: home damage is the most cited consequence in both countries, followed by loss of income and loss of crops or livestock. These are not abstract climate metrics, they are the erosion of household balance sheets and rural livelihoods, one storm at a time. Concern about future risk tracks the same pattern: 58% of Filipino respondents describe themselves as "very concerned" about future extreme weather, compared to 46% of Colombians, though majorities in both countries are at least somewhat worried.

The Quiet Crisis Underneath the Storms

If typhoons and floods are the acute shocks, water and health are the chronic stresses compounding them, and here the two countries converge more than they diverge. Roughly three-quarters of respondents in both countries say they have been concerned in the past month about having enough clean water for drinking and hygiene. That concern tracks closely with self-reported illness: over half of all respondents report a household case of cough or cold in the past 30 days, and roughly a quarter report diarrhoea or stomach illness, both conditions closely linked to water quality and sanitation.

The infrastructure behind these numbers tells the deeper story. Colombian households are considerably more likely to have piped water directly into the home (74%, versus 15% in the Philippines) and centralized sewage connections (74%, versus 17%). Filipino households, by contrast, rely heavily on commercial water delivery services, a source vulnerable to price spikes and logistical breakdowns precisely when disasters strike hardest.

This infrastructure gap widens further when it comes to the health system's capacity to absorb the shock. Colombians report markedly easier and more affordable access to healthcare than Filipinos - a difference of roughly 20 points on both access and affordability. In practice, this means the country experiencing the more severe and frequent weather shocks also has the thinner healthcare safety net to respond to them. That is precisely the kind of compounding vulnerability that turns a bad storm season into a public health emergency.

One modest bright spot: trust in public health officials is relatively high in both countries, with nearly 90% of respondents expressing at least some trust. That reservoir of institutional credibility is an underused asset — one that could be leveraged for crisis communication and response coordination before it erodes.

Migration Is No Longer a Hypothetical

Perhaps the most consequential finding for the security community concerns mobility. Nearly a quarter of respondents overall, 27% in the Philippines, 19% in Colombia, say they have seriously considered moving in the next 12 months specifically because of weather-related risk. That is a striking figure when set against the historical baseline: among people who have already relocated from their birth region, only about 7% cite disaster or conflict displacement as the primary driver, with the overwhelming majority moving for economic opportunity or family reasons.

In other words, climate is emerging as a distinct and rapidly growing driver of mobility decisions. One that barely registers in historical migration data but now shows up as a live consideration for one in four Filipinos and nearly one in five Colombians. Notably, Colombia enacted legislation in 2026 formally recognizing climate-driven displacement, an early signal that the policy conversation is starting to catch up with the underlying trend.

What This Means for Policy

Three implications stand out for practitioners in foreign relations, development, and security:

Climate resilience is now a security investment, not just a development one. The Philippines data in particular shows how repeated physical damage to homes and infrastructure erodes community resilience over time, creating openings that non-state actors or strategic competitors can exploit. Coastal defences, hardened water systems, and evacuation infrastructure increasingly belong in the same conversation as traditional security cooperation.

Health security and climate security are converging. The combination of high illness prevalence, near-universal water concern, and in the Philippines, a healthcare system under real affordability strain points to a specific vulnerability: a major storm season could translate directly into a public health crisis with limited absorptive capacity. Fusing environmental monitoring with public health surveillance, and shoring up healthcare affordability specifically, is a concrete, near-term intervention.

Migration policy needs to get ahead of the trend, not react to it. With roughly a fifth to a quarter of both populations already weighing weather-driven relocation, the window to shape orderly, planned approaches to climate mobility, rather than responding to unplanned displacement after the fact, is open now. Colombia's new legal framework offers a starting point for regional dialogue, potentially through bodies like ASEAN or the OAS, before displacement pressures outpace the policy response. 

The Bottom Line

The data from Colombia and the Philippines makes a case that is easy to state and hard to act on: climate impacts have stopped being a future risk to plan around and have become a present condition to manage. The two countries arrived at broadly similar levels of anxiety and migration consideration by different routes — one through the sheer frequency of typhoon damage, the other through infrastructure and health-system gaps compounding a lower rate of acute shocks. For the foreign policy and security community, the lesson is that climate resilience, health system capacity, and migration policy are no longer three separate portfolios. Increasingly, they are the same portfolio.
