The villages and homes of Alaska are at risk from the thaw.
Warming temperatures will cause frozen ground to thaw and cause cracked homes, buckled roads, and broken pipes in and near the Arctic.
There are five million people on the northern part of the planet.
Climate change is causing the planet to warm two to four times faster than before.
One Alaska resident said the land changes before them.
70% of infrastructure and 30% of critical infrastructure are at high risk of damage by the year 2050, with a projected cost of tens of billions of dollars.
The study published on Tuesday shows how climate change is expected to threaten life as well as the natural world.
Everyone living on permafrost is struggling, according to Kaare Sikuaq Erickson. He is a cultural mediator in Alaska.
tundra is defined as land that has been frozen continuously for more than two years. Half of Canada's land and 80% of Alaska's are covered by it.
Warming temperatures are causing parts of it to thaw with unpredictable effects, such as land slips and flooding.
Prof Jan Hjort, lead author of the study, says that the warming of the climate causes the permafrost to thaw, which threatens existing infrastructure and future construction projects.

The village of Unalakleet, Alaska, is near the Bering Sea.
Imagine living on a block of ice and constantly trying to keep it cold.
It affects everything from digging foundations for a house to installing sewer and water systems.
He says that the ice is warming fast. You can see the foundations of buildings and highways are not stable.
The US government divided up the land after colonization in the 19th and 20th centuries, which made it difficult for indigenous villages to move.
Up to 80% of buildings in some Russian cities are damaged by the weather, according to research. The landscape in Russia is degrading and it is affecting food security, traditional lifestyles and accessibility.
As the heating of the planet is projected to accelerate in coming years, more permafrost is expected to thaw, threatening infrastructure and communities.
There are at least 120,000 buildings, 40,000 km of roads and 9,500 km of pipelines located in the northern hemisphere, according to a study.
The whole landscape of the north is dependent on the threshold of zero degrees Celsius. Louise Farquharson from the University of Fairbanks, Alaska, said that there are huge waves of problems as the surface temperature approaches zero.
Water mains are rupturing and houses are becoming unstable in some communities she studies. Due to the ponds forming from the meltwater, it's become dangerous to play outside.
She says it's important to point out that people have lived in these landscapes for thousands of years.

The mounds in Siberia are caused by the thaw of the permafrost.
Evidence of the impact of warming permafrost was clear in 2020 when a huge oil spill caused one of Russia's worst environmental disasters.
In Russia's north, diesel poured from Norilsk Nickel's storage tanks into rivers and lakes. The tanks sank after they became unstable.
The research shows that it is possible to keep the permafrost cool with different building design. It is risky and expensive.
The air convection embankments are already built on some highways in Alaska. This method places porous stones inside the road to encourage heat to rise.
"Lowering our dependency on greenhouse gases is a sensible solution that most scientists agree on," says Dr. Christoffersen, a glaciologist at the Scott Polar Research Institute in Cambridge, UK.
It's always been difficult to live in the north, but we will carry on, but it's getting harder for our people.
Scientists are analyzing the frozen land to see how much carbon dioxide is being released as it warms.
The research is in the journal Nature Reviews Earth & Environment.
