29 examples of Permafrost in a sentence

As Earth warms, now because of extra CO2 we put in the atmosphere, ice will melt, and CO2 and methane will be released by warming ocean and melting permafrost.
Methane is also beginning to escape from the permafrost.
We exhumed six bodies who had died of Spanish flu and were buried in the permafrost and we hoped the frozen ground would preserve the body and the virus.
Fortunately, we find millions of their remains strewn across the permafrost buried deep in Siberia and Alaska, and we can actually go up there and actually take them out.
Not surprising then again that a mammoth preserved in the permafrost will have something on the order of 50 percent of its DNA being mammoth, whereas something like the Columbian mammoth, living in a temperature and buried in a temperate environment over its laying-in will only have 3 to 10 percent endogenous.
So this landscape would be easily able to house it, and I have to admit that there [is] a part of the child in me, the boy in me, that would love to see these majestic creatures walk across the permafrost of the north once again, but I do have to admit that part of the adult in me sometimes wonders whether or not we should.
The Arctic region consists of a vast, ice-covered ocean surrounded by treeless permafrost.
Management of forests, transportation, the oceans, the melting of the permafrost.
Your research team has found a prehistoric virus preserved in the permafrost and isolated it for study.
That leaves less than 1% available for sustaining all life on Earth, spread across our planet in rivers, lakes, underground aquifers, ground ice and permafrost.
These peatlands have a permanently frozen ground underneath, the permafrost, and the carbon was able to build up in these soils over long periods of time because even though plants are able to photosynthesize during the short, warm summer months, the environment quickly turns cold and dark, and then microbes are not able to efficiently break down the residue.
But right now, with atmospheric warming, the permafrost is thawing and draining.
If just three percent of the carbon locked up in the arctic permafrost is released as the world warms, it would offset all the savings that we need to make, in carbon, over the next 40 years to avoid runaway climate change.
And what they found, by doing research into the permafrost, was this bacteria.
It's also probably one the most vulnerable of the oldest living things, because if the permafrost melts, it won't survive.
They've survived for millennia in desert, in the permafrost, at the tops of mountains and at the bottom of the ocean.
Seemingly dramatic changes in weather patterns – including the melting of glaciers in Greenland and the thawing of the Siberian permafrost – have at last convinced most business leaders that the time for action is now.
Thawing Siberian permafrost will release vast quantities of methane.
For example, further warming would release large quantities of methane – a more potent greenhouse gas than carbon dioxide – from thawing Siberian permafrost, leading to more warming, more thawing, and more methane in the atmosphere.
Warming from any climate pollutant is dangerous and sets in motion a series of potentially irreversible effects, including the continued rise of sea levels, destruction of forests, depletion of Arctic sea ice and glaciers in Greenland and the Tibetan Plateau, and melting of permafrost.
A more promising one lies beneath the permafrost of Prudhoe Bay, the big oil-producing region on the arctic coast of Alaska.
That is a conservative estimate, and if warming proceeds more rapidly because of the loss of the reflectivity of Arctic ice and the release of CO2 and methane from thawing permafrost, rising sea levels could lead to the submersion of low-lying islands and hence threaten the survival of entire nations.
Without this icy shield to reflect heat back into space, warming accelerates, permafrost melts, and ancient stores of methane and CO2 are returned to the atmosphere.
As Brezhnev put it, the BAM was “the construction project of the century,” pushing, cutting, and tunneling its way through thousands of miles of rivers, forests, and cliffs usually covered in permafrost.
If this produces large-scale melting of the permafrost, huge amounts of trapped methane gas will be released, causing climate change to accelerate.
Compounding the problem of accelerating Arctic warming is the self-reinforcing feedback risk of permafrost thawing.
With about twice as much carbon locked away in permafrost as is already in the atmosphere, releasing even some of it could be disastrous.
And there is growing concern that as the Siberian permafrost melts, long-frozen deadly viruses will resurface and quickly spread around the world like COVID-19 did.
However, the same trend has also fueled the loss of permafrost, threatening billions of dollars’ worth of infrastructure that may soon be standing in mud instead of on firm ground.
