When people discuss climate change, most envision melting glaciers, smoke-filled skies from wildfires, or hurricanes ravaging coastlines. However, another crisis is unfolding in Canada’s North, one that is quieter but just as perilous: the melting of permafrost.
Permafrost is ground that has remained frozen for at least two years, though in many places, it has been frozen for thousands of years. It is a mix of soil, rock, and ice, and it covers almost half of Canada’s landmass, particularly in the Arctic. Think of it like the Earth’s natural deep freezer. Inside it are ancient plants, animal remains, and vast amounts of carbon that have been trapped and locked away for millennia.
As long as the permafrost stays frozen, those gases remain contained. But now, as temperatures rise and the Arctic warms nearly four times faster than the global average, that freezer door is swinging wide open.
Why the Arctic Matters to Everyone
It might be tempting to think of the Arctic as far away, remote, untouched, or disconnected from daily life in southern Canada. But the reality is that what happens in the Arctic affects everyone. Permafrost contains almost twice as much carbon as is currently in the Earth’s atmosphere. When it melts, that carbon escapes in the form of carbon dioxide and methane, two of the most potent greenhouse gases.
This creates a dangerous cycle: warmer air melts permafrost, which releases greenhouse gases, and those gases in turn contribute to even greater warming of the Earth. Scientists refer to this as a “feedback loop.” If large amounts of permafrost thaw, the gases released could overwhelm even the strongest climate policies, making it almost impossible to slow global warming.
The ripple effects are already visible. Melting permafrost worsens heatwaves in Ontario, intensifies wildfires in Alberta and British Columbia, and fuels stronger Atlantic storms. Rising global temperatures also bring increased insurance premiums, higher food prices, and strained infrastructure due to new climate extremes. The Arctic may be far north, but it is the beating heart of global climate stability.
Impacts Close to Home in Canada
For northern communities, the impacts of melting permafrost are immediate and deeply personal. Buildings, schools, and homes that were once stable on frozen foundations are cracking and sinking. Road’s twist and buckle, airstrips become unsafe, and pipelines leak as the ground beneath them shifts. This is not just inconvenient; it is life-threatening, as these systems provide access to food, medical care, and basic supplies in places already cut off from southern infrastructure.
The hamlet of Tuktoyaktuk, Northwest Territories, sits on the edge of the Arctic Ocean. As the permafrost beneath it thaws, the coastline is collapsing at an alarming rate of several meters each year. Entire homes have already been moved inland, and Elders warn that parts of the community may disappear into the sea within a generation. For residents, this is not just about losing land but losing ancestral ties to a place that has always been home.
In Inuvik, Northwest Territories, traditional underground ice cellars, once reliable food storage systems for generations, are collapsing into the permafrost. Families now face soaring costs to ship in groceries; undermining food security and cultural practices tied to country food.
Even the transportation routes that connect the North to the South are threatened. In the Yukon, the Dempster Highway, Canada’s only all-season road to the Arctic coast, is buckling as thawing permafrost destabilizes its foundation. Engineers are racing to repair roads that were never designed for melting ground, costing governments tens of millions of dollars each year.
And the South is not spared. The carbon released from permafrost melt contributes to the greenhouse gases driving climate extremes across Canada, including hotter summers in Toronto, devastating wildfires in Kelowna, severe flooding along the St. Lawrence, and worsening droughts on the Prairies. What melts in the North shapes life everywhere else.
Why Permafrost is Sacred in Indigenous Worldviews
For Indigenous Peoples of the Arctic, permafrost is not just frozen soil; it is a living part of their homeland and identity. Inuit, First Nations, and Métis Peoples have lived in relationship with frozen ground for thousands of years. The permafrost preserves sacred sites, traditional travel routes, and hunting lands. It has long been a source of stability, shaping the balance of ecosystems and making possible the cultural practices that sustain communities.
For Inuit in particular, permafrost has always been a trusted partner in food security. Ice cellars dug into the ground kept caribou, seal, fish, and whale meat fresh throughout the year. This practice is not only efficient and sustainable but also deeply cultural, tying families to cycles of harvest and sharing. As the permafrost melts and these cellars collapse, Inuit food systems are being disrupted. Families must rely more heavily on expensive store-bought food, which undermines both health and cultural sovereignty.
The thaw also threatens sacred spaces. Burial grounds are being disturbed, rivers and lakes are shifting, and the plants and animals that communities depend on are disappearing. In Indigenous worldviews, the land is kin alive and relational. When the permafrost melts, it signals not just an environmental crisis but a breaking of relationships that have been nurtured since time immemorial.
The Human Face of Melting Permafrost
The impacts of permafrost melt cannot be measured solely in terms of carbon emissions or financial costs. They must also be seen in the daily lives of the people who call the North home. In some communities, houses tilt and become uninhabitable, forcing residents to relocate, which disrupts family life, education, and mental health. In others, health centres and schools need constant repair, straining already limited budgets.
Travel across the land, once a predictable and safe experience, is now risky. Snowmobiles break through thinning ice. Trails flood or erode unexpectedly. Hunters face danger simply by trying to continue practices that have sustained their people for millennia.
For many Indigenous families, this is not only about the loss of infrastructure but also the loss of identity. When permafrost thaws, so do the practices tied to it: storing food, travelling safely, caring for burial sites, and teaching youth how to live in balance with the land. These changes erode culture, language, and ways of knowing that are inseparable from place.
Why the World Should Pay Attention
The melting of permafrost is not just a northern problem it is a global alarm bell. Scientists estimate that if even a fraction of the carbon stored in permafrost is released, it could equal the emissions from decades of current human activities. This is enough to derail international climate targets and lock the planet into a state of runaway warming.
This matters for everyone. Rising seas will not stop at Canada’s borders; they will flood coastal cities around the globe. Droughts and crop failures will disrupt food supplies and drive-up prices worldwide. Heatwaves will claim more lives in cities already struggling to keep cool. Economic costs will skyrocket, from insurance payouts to rebuilding disaster-hit communities. If the permafrost continues to thaw unchecked, the climate shocks of the past decade will look mild compared to what lies ahead.
But beyond the science, there is also a moral responsibility. The Arctic has contributed the least to climate change yet is suffering some of its most significant impacts. Indigenous communities, which have lived sustainably for generations, are now bearing the brunt of global emissions. For the world to ignore this crisis is to accept an injustice that will echo through history.
The Arctic is often referred to as the “canary in the coal mine” for climate change, but it is more than a warning system; it is a driver of global stability. If we lose the permafrost, we risk losing the fight against climate change altogether. Paying attention to what is happening in the Arctic is not optional. It is a test of whether humanity can listen, learn, and act before it is too late.
Moving Forward: Responsibility and Action
Addressing permafrost melt means tackling climate change at its root: cutting greenhouse gas emissions and transitioning to renewable energy. Canada must lead in reducing its dependence on oil and gas while investing in clean energy and climate-resilient infrastructure. But technical fixes alone are not enough. Indigenous-led monitoring, adaptation, and governance must be supported and prioritized.
In Nunavut and the Northwest Territories, Indigenous guardians and community researchers are already combining traditional knowledge with Western science to track permafrost thaw, monitor wildlife, and pilot new forms of housing built for unstable ground. These projects demonstrate that solutions are most effective when they originate from the individuals most closely connected to the land.
For families in southern Canada, the issue may seem distant. However, the truth is that every decision matters. The energy we use, the food we waste, and the products we buy all contribute to the warming that melts permafrost. By reducing consumption, supporting Indigenous-led initiatives, and advocating for robust climate policies, households far from the Arctic can still play a role in protecting it.
The permafrost is melting. It is reshaping the Arctic, altering Canada, and posing a threat to global climate stability. However, it also offers us a choice: to continue down a path of denial, or to act guided by science, led by Indigenous knowledge, and rooted in care for the generations to come.

Melting Ground: Why Permafrost Matters for Climate Change and Indigenous Peoples
N.C. Gov. Josh Stein wants state lawmakers to rethink tax breaks for data centers. The industry’s opacity makes it difficult to evaluate costs and benefits.
Tax breaks for data centers in North Carolina keep as much as $57 million each year into from state and local government coffers, state figures show, an amount that could balloon to billions of dollars if all the proposed projects are built.
The Global Environment Facility (GEF), a multilateral fund that provides climate and nature finance to developing countries, has raised $3.9 billion from donor governments in its last pledging session ahead of a key fundraising deadline at the end of May.
The amount, which is meant to cover the fund’s activities for the next four years (July 2026-June 2030), falls significantly short of the previous four-year cycle for which the GEF managed to raise $5.3bn from governments. Since then, military and other political priorities have squeezed rich nations’ budgets for climate and development aid.
The facility said in a statement that it expects more pledges ahead of the final replenishment package, which is set for approval at the next GEF Council meeting from May 31 to June 3.
Claude Gascon, interim CEO of the GEF, said that “donor countries have risen to the challenge and made bold commitments towards a more positive future for the planet”. He added that the pledges send a message that “the world is not giving up on nature even in a time of competing priorities”.

Donors under pressure
But Brian O’Donnell, director of the environmental non-profit Campaign for Nature, said the announcement shows “an alarming trend” of donor governments cutting public finance for climate and nature.
“Wealthy nations pledged to increase international nature finance, and yet we are seeing cuts and lower contributions. Investing in nature prevents extinctions and supports livelihoods, security, health, food, clean water and climate,” he said. “Failing to safeguard nature now will result in much larger costs later.”
At COP29 in Baku, developed countries pledged to mobilise $300bn a year in public climate finance by 2035, while at UN biodiversity talks they have also pledged to raise $30bn per year by 2030. Yet several wealthy governments have announced cuts to green finance to increase defense spending, among them most recently the UK.
As for the US, despite Trump’s cuts to international climate finance, Congress approved a $150 million increase in its contribution to the GEF after what was described as the organisation’s “refocus on non-climate priorities like biodiversity, plastics and ocean ecosystems, per US Treasury guidance”.
The facility will only reveal how much each country has pledged when its assembly of 186 member countries meets in early June. The last period’s largest donors were Germany ($575 million), Japan ($451 million), and the US ($425 million).
The GEF has also gone through a change in leadership halfway through its fundraising cycle. Last December, the GEF Council asked former CEO Carlos Manuel Rodriguez to step down effective immediately and appointed Gascon as interim CEO.

New guidelines
As part of the upcoming funding cycle, the GEF has approved a set of guidelines for spending the $3.9bn raised so far, which include allocating 35% of resources for least developed countries and small island states, as well as 20% of the money going to Indigenous people and communities.
Its programs will help countries shift five key systems – nature, food, urban, energy and health – from models that drive degradation to alternatives that protect the planet and support human well-being by integrating the value of nature into production and consumption systems.
The new priorities also include a target to allocate 25% of the GEF’s budget for mobilising private funds through blended finance. This aligns with efforts by wealthy countries to increase contributions from the private sector to international climate finance.
Niels Annen, Germany’s State Secretary for Economic Cooperation and Development, said in a statement that the country’s priorities are “very well reflected” in the GEF’s new spending guidelines, including on “innovative finance for nature and people, better cooperation with the private sector, and stable resources for the most vulnerable countries”.
Aliou Mustafa, of the GEF Indigenous Peoples Advisory Group (IPAG), also welcomed the announcement, adding that “the GEF is strengthening trust and meaningful partnerships with Indigenous Peoples and local communities” by placing them at the “centre of decision-making”.

Tropical cyclones that rapidly intensify when passing over marine heatwaves can become “supercharged”, increasing the likelihood of high economic losses, a new study finds.
Such storms also have higher rates of rainfall and higher maximum windspeeds, according to the research.
The study, published in Science Advances, looks at the economic damages caused by nearly 800 tropical cyclones that occurred around the world between 1981 and 2023.
It finds that rapidly intensifying tropical cyclones that pass near abnormally warm parts of the ocean produce nearly double – 93% – the economic damages as storms that do not, even when levels of coastal development are taken into account.
One researcher, who was not involved in the study, tells Carbon Brief that the new analysis is a “step forward in understanding how we can better refine our predictions of what might happen in the future” in an increasingly warm world.
As marine heatwaves are projected to become more frequent under future climate change, the authors say that the interactions between storms and these heatwaves “should be given greater consideration in future strategies for climate adaptation and climate preparedness”.
‘Rapid intensification’
Tropical cyclones are rapidly rotating storm systems that form over warm ocean waters, characterised by low pressure at their cores and sustained winds that can reach more than 120 kilometres per hour.
The term “tropical cyclones” encompasses hurricanes, cyclones and typhoons, which are named as such depending on which ocean basin they occur in.
When they make landfall, these storms can cause major damage. They accounted for six of the top 10 disasters between 1900 and 2024 in terms of economic loss, according to the insurance company Aon’s 2025 climate catastrophe insight report.
These economic losses are largely caused by high wind speeds, large amounts of rainfall and damaging storm surges.
Storms can become particularly dangerous through a process called “rapid intensification”.
Rapid intensification is when a storm strengthens considerably in a short period of time. It is defined as an increase in sustained wind speed of at least 30 knots (around 55 kilometres per hour) in a 24-hour period.
There are several factors that can lead to rapid intensification, including warm ocean temperatures, high humidity and low vertical “wind shear” – meaning that the wind speeds higher up in the atmosphere are very similar to the wind speeds near the surface.
Rapid intensification has become more common since the 1980s and is projected to become even more frequent in the future with continued warming. (Although there is uncertainty as to how climate change will impact the frequency of tropical cyclones, the increase in strength and intensification is more clear.)
Marine heatwaves are another type of extreme event that are becoming more frequent due to recent warming. Like their atmospheric counterparts, marine heatwaves are periods of abnormally high ocean temperatures.
Previous research has shown that these marine heatwaves can contribute to a cyclone undergoing rapid intensification. This is because the warm ocean water acts as a “fuel” for a storm, says Dr Hamed Moftakhari, an associate professor of civil engineering at the University of Alabama who was one of the authors of the new study. He explains:
“The entire strength of the tropical cyclone [depends on] how hot the [ocean] surface is. Marine heatwave means we have an abundance of hot water that is like a gas [petrol] station. As you move over that, it’s going to supercharge you.”
However, the authors say, there is no global assessment of how rapid intensification and marine heatwaves interact – or how they contribute to economic damages.
Using the International Best Track Archive for Climate Stewardship (IBTrACS) – a database of tropical cyclone paths and intensities – the researchers identify 1,600 storms that made landfall during the 1981-2023 period, out of a total of 3,464 events.
Of these 1,600 storms, they were able to match 789 individual, land-falling cyclones with economic loss data from the Emergency Events Database (EM-DAT) and other official sources.
Then, using the IBTrACS storm data and ocean-temperature data from the European Centre for Medium-Range Weather Forecasts, the researchers classify each cyclone by whether or not it underwent rapid intensification and if it passed near a recent marine heatwave event before making landfall.
The researchers find that there is a “modest” rise in the number of marine heatwave-influenced tropical cyclones globally since 1981, but with significant regional variations. In particular, they say, there are “clear” upward trends in the north Atlantic Ocean, the north Indian Ocean and the northern hemisphere basin of the eastern Pacific Ocean.
‘Storm characteristics’
The researchers find substantial differences in the characteristics of tropical cyclones that experience rapid intensification and those that do not, as well as between rapidly intensifying storms that occur with marine heatwaves and those that occur without them.
For example, tropical cyclones that do not experience rapid intensification have, on average, maximum wind speeds of around 40 knots (74km/hr), whereas storms that rapidly intensify have an average maximum wind speed of nearly 80 knots (148km/hr).
Of the rapidly intensifying storms, those that are influenced by marine heatwaves maintain higher wind speeds during the days leading up to landfall.
Although the wind speeds are very similar between the two groups once the storms make landfall, the pre-landfall difference still has an impact on a storm’s destructiveness, says Dr Soheil Radfar, a hurricane-hazard modeller at Princeton University. Radfar, who is the lead author of the new study, tells Carbon Brief:
“Hurricane damage starts days before the landfall…Four or five days before a hurricane making landfall, we expect to have high wind speeds and, because of that high wind speed, we expect to have storm surges that impact coastal communities.”
They also find that rapidly intensifying storms have higher peak rainfall than non-rapidly intensifying storms, with marine heatwave-influenced, rapidly intensifying storms exhibiting the highest average rainfall at landfall.
The charts below show the mean sustained wind speed in knots (top) and the mean rainfall in millimetres per hour (bottom) for the tropical cyclones analysed in the study in the five days leading up to and two days following a storm making landfall.
The four lines show storms that: rapidly intensified with the influence of marine heatwaves (red); those that rapidly intensified without marine heatwaves (purple); those that experienced marine heatwaves, but did not rapidly intensify (orange); and those that neither rapidly intensified nor experienced a marine heatwave (blue).
Dr Daneeja Mawren, an ocean and climate consultant at the Mauritius-based Mascarene Environmental Consulting who was not involved in the study, tells Carbon Brief that the new study “helps clarify how marine heatwaves amplify storm characteristics”, such as stronger winds and heavier rainfall. She notes that this “has not been done on a global scale before”.
However, Mawren adds that other factors not considered in the analysis can “make a huge difference” in the rapid intensification of tropical cyclones, including subsurface marine heatwaves and eddies – circular, spinning ocean currents that can trap warm water.
Dr Jonathan Lin, an atmospheric scientist at Cornell University who was also not involved in the study, tells Carbon Brief that, while the intensification found by the study “makes physical sense”, it is inherently limited by the relatively small number of storms that occur. He adds:
“There’s not that many storms, to tease out the physical mechanisms and observational data. So being able to reproduce this kind of work in a physical model would be really important.”
Economic costs
Storm intensity is not the only factor that determines how destructive a given cyclone can be – the economic damages also depend strongly on the population density and the amount of infrastructure development where a storm hits. The study explains:
“A high storm surge in a sparsely populated area may cause less economic damage than a smaller surge in a densely populated, economically important region.”
To account for the differences in development, the researchers use a type of data called “built-up volume”, from the Global Human Settlement Layer. Built-up volume is a quantity derived from satellite data and other high-resolution imagery that combines measurements of building area and average building height in a given area. This can be used as a proxy for the level of development, the authors explain.
By comparing different cyclones that impacted areas with similar built-up volumes, the researchers can analyse how rapid intensification and marine heatwaves contribute to the overall economic damages of a storm.
They find that, even when controlling for levels of coastal development, storms that pass through a marine heatwave during their rapid intensification cause 93% higher economic damages than storms that do not.
They identify 71 marine heatwave-influenced storms that cause more than $1bn (inflation-adjusted across the dataset) in damages, compared to 45 storms that cause those levels of damage without the influence of marine heatwaves.
This quantification of the cyclones’ economic impact is one of the study’s most “important contributions”, says Mawren.
The authors also note that the continued development in coastal regions may increase the likelihood of tropical cyclone damages over time.
Towards forecasting
The study notes that the increased damages caused by marine heatwave-influenced tropical cyclones, along with the projected increases in marine heatwaves, means such storms “should be given greater consideration” in planning for future climate change.
For Radfar and Moftakhari, the new study emphasises the importance of understanding the interactions between extreme events, such as tropical cyclones and marine heatwaves.
Moftakhari notes that extreme events in the future are expected to become both more intense and more complex. This becomes a problem for climate resilience because “we basically design in the future based on what we’ve observed in the past”, he says. This may lead to underestimating potential hazards, he adds.
Mawren agrees, telling Carbon Brief that, in order to “fully capture the intensification potential”, future forecasts and risk assessments must account for marine heatwaves and other ocean phenomena, such as subsurface heat.
Lin adds that the actions needed to reduce storm damages “take on the order of decades to do right”. He tells Carbon Brief:
“All these [planning] decisions have to come by understanding the future uncertainty and so this research is a step forward in understanding how we can better refine our predictions of what might happen in the future.”
