➔ One-quarter of the northern hemisphere’s land is permanently frozen or frozen for extended periods

➔ The planet’s warming has been most rapid in the far north, where rising heat simply melts permanently frozen land

➔ Infrastructure of every kind, from buildings, roads, and railways, to pipelines, airports, and power lines come under stress or are damaged when the rate of melting is accelerated

➔ The entire infrastructure of the far north and the world’s coldest zones is affected

➔ Overall, the effect is estimated to accelerate by around 10–20% the rate of wear and tear on all exposed infrastructure in the near term
