Historical past and geography lecturers typically level out the silliness of Greenland’s title. The Arctic nation is roofed with a barren ice sheet spanning 660,000 sq. miles, or roughly 80% of the nation’s floor. There’s not precisely a lot inexperienced to be discovered!
In line with the Icelandic Sagas, Eric the Pink, who had been exiled from Iceland for homicide, got here to Greenland’s glacial shores within the late tenth century and dubbed the place “Grœnland” within the hopes of attracting settlers to the distant outpost with the false promise of ample forests and fields.
He could have been just a bit forward of his time. Analysis reveals that within the not-too-distant future, local weather change might soften the perimeters of Greenland’s ice sheet, opening up fertile soil for brand spanking new seeds and crops to take maintain. However would a greener Greenland be good for the nation—or the planet?
Warming Ice, Rising Waters
The Greenland ice sheet is dropping a median of round 250 billion metric tons of ice per yr—and these losses have proven to be rushing up over time. The ice comprises sufficient water to boost international sea ranges by 24 toes if all of it melted. The yr 2021 marked the twenty fifth yr in a row by which the ice sheet misplaced extra mass in the course of the melting season than it gained in the course of the winter.
Heat air temperatures trigger melting to happen on the floor of the ice sheet, a course of that’s liable for round half the ice Greenland loses every year. The opposite half comes from glaciers on the ice sheet’s edge crumbling into the ocean. When that occurs, it churns up the waters—and that turbulence helps warmth stand up from deeper components of the ocean, warming the waters coming into contact with the ice and melting the glaciers even sooner.
Because of this, Greenland, researchers predict, might quickly start to look just a little bit like Alaska or western Canada, although the precise composition of bushes and bushes relies upon upon which species benefit from the brand new ecological niches that type when ice uncovers soil.

Greenland’s Uniquely Unpopulated Ecosystem
Greenland is particular in so some ways relating to ecological conservation. Though it’s the Twelfth-largest nation on the earth (it’s roughly the scale of Western Europe or the primary a part of the U.S.), Greenland has the bottom inhabitants density of any nation on the planet. Solely 56,000 individuals name Greenland dwelling; in the event that they had been all to unfold out, every Greenlander would have about 25 sq. miles to themselves.
All the northeast of Greenland is one large nationwide park that was established in 1974. It’s the most important nationwide park on the earth and a sanctuary for Arctic wildlife such because the Arctic fox, collared lemming, Arctic hare and grey wolves.
With so few individuals and even fewer automobiles and trade (the longest street for automobiles within the nation is barely round 20 miles lengthy), Greenland additionally has among the purest air on the earth. You’ll be able to drink freely from any of the streams or rivers within the nation—no filter required.
Greenland is already greener than most guests on our East Greenland Arctic Journey count on. Colourful flowers, lush meadows and hardy crops spring up when the snow begins to soften and the summer season’s gentle winds blow. Our Expedition Leaders even information our visitors into a spot known as the Valley of Flowers, the place stunning lakes are ringed with wildflowers.
> Learn: What Local weather Change Will Imply for Greenland’s Arctic Wildflowers
The vegetation is richest and most numerous within the southwest, which, in comparison with the remainder of the nation, has a comparatively gentle local weather with wooded areas within the protected internal fjords. Elsewhere in Greenland, there are tundras with grasses and sedges, carpets of moss, mushrooms, flowering crops like lavatory rosemary and yellow poppy, and blueberry and crowberry bushes.
Non-native Vegetation Take Maintain because the Planet Heats Up
In 1911, researchers reported that Greenland was dwelling to 310 species of vascular crops, together with 15 endemic species. In the present day that quantity has jumped as much as almost 500 species and rising. Virtually all of Greenland’s native vegetation disappeared in the course of the ice age; the prevailing plants got here largely from North America.
How’s that? Nicely, a examine performed in Svalbard, an archipelago north of Norway with the same ecosystem as Greenland, discovered 1,019 seeds of 53 species clinging to only 259 vacationers’ footwear upon arrival. Twenty-six of these species germinated in Arctic circumstances when given the chance. Migratory birds coming from North America have additionally been discovered to deposit seeds that had been caught to their plumage and toes or handed by way of their bowels.
At the moment, solely 5 species of bushes or massive shrubs happen naturally in Greenland: Greenland mountain ash, mountain alder, downy birch, grayleaf willow, and customary juniper. Even these presently develop solely in scattered plots within the far south.
Nonetheless, subject experiments have confirmed {that a} vary of different species, together with Siberian larch, white spruce, lodgepole pine and Japanese balsam poplar, might set up in Greenland if given the prospect. These species, together with the 5 long-established native varieties, could start to unfold as temperatures heat with local weather change.
Researchers constructed a pc mannequin of Greenland’s predicted local weather for the following 100 years, onto which they overlaid with recognized knowledge for numerous North American and European tree species’ ideally suited habitat niches. Inside a century, they discovered, all 56 species of bushes and shrubs they examined would probably be ideally suited to take up residence (or broaden their attain) in Greenland.
With out assist, the researchers’ fashions point out that some species of bushes would take round 2,000 years to seek out their solution to a newly hospitable patch of Greenland soil. However with tourism and common flights between continents, the crops will almost definitely obtain some important unintended colonization help. Greenlanders will even almost definitely begin to plant bushes themselves, in the event that they imagine they may now develop there.
“Individuals typically plant utility and decorative crops the place they’ll develop,” Jens-Christian Svenning, a biologist at Aarhus College, states. “I imagine it lies in our human nature.” Nonetheless, he warns that if Greenland’s greening is left as much as the locals, they need to proceed with warning.
“The Greenlandic countryside can be much more vulnerable to launched species sooner or later than it’s as we speak,” he stated. “So if importing and planting species takes place with none management, this might result in nature growing in a really chaotic approach.”
Why Inexperienced Isn’t All the time Nice
Whereas “extra inexperienced” would possibly appear like a win for the setting, the doable shift from mossy tundra to towering forest would virtually actually push out a few of Greenland’s native plant and animal species.
On the flip facet, new bushes could assist alleviate among the erosion points from rapidly melting glaciers and will create leisure or financial prospects, similar to sustainable searching and foraging for wooden and wild edible meals. Even only recently, the warming of the Arctic setting has allowed new crops like apples, strawberries, broccoli, cauliflower, cabbage and carrots to be grown and for the cultivated areas of the nation to be prolonged.

Native Greenlanders are already having to adapt to climate adjustments. Kaleeraq Mathaeussen, for instance, has been fishing since he was 14 years previous. Like different locals, he has noticed large adjustments round him that may’t be ignored. Previously, he used to journey on the ice every winter with a sled pulled by his beloved canine. However the water now not freezes prefer it used to.
“Ever since 2001, I observed the winter seasons in Disko Bay didn’t have as a lot ice. I used to be very fearful once I began to note that the ice barrier was getting weaker. In the present day it’s unpredictable and too harmful to go fishing with my sled canine,” he explains.
Mathaeussen stopped sledding two years in the past, and now he solely feels secure fishing by boat.
And Mathaeussen isn’t alone. Round 20 years in the past there have been round 5,000 canine within the bigger coastal city of Ilulissat alone, however now there are solely about 1,800, as many Greenlanders surrender this conventional transportation methodology.
“There’s some unfavorable issues. There are additionally some optimistic issues,” Mathaeussen states. He explains that in some methods, Arctic life has turn out to be simpler. For example, vitamins from glacial meltwater are enriching marine life, and with the hotter climate, it’s now doable to fish year-round by boat. Halibut fetch a excessive worth, and fishermen like Mathaeussen are actually financially higher off as a result of they’ll fish for an extended season.

Expertise Greenland Local weather and Tradition Up Shut
With all of those adjustments occurring comparatively rapidly, the time to go to Greenland is now. On Nat Hab’s East Greenland Arctic Journey, vacationers have the prospect to talk to locals firsthand to get their perspective on how local weather change is affecting—and can have an effect on—them.
Along with our time at our Base Camp, we spend time within the tiny village of Tinit, a 20-minute boat trip from camp. Most guests by no means get to those distant communities, however our in a single day stays enable us to fulfill the native Greenlandic Inuit, find out about their tradition and traditions, and acquire an appreciation for the challenges and rewards of life in a quickly altering trendy Greenland.
Take into account an upcoming Nat Hab journey to Greenland as the proper place to unplug, join with nature, and see for your self the influence of local weather change within the Arctic.
