Historical past and geography academics usually level out the silliness of Greenland’s identify. 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 accordance with the Icelandic Sagas, Eric the Purple, 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 plentiful forests and fields.
He could have been just a bit forward of his time. Analysis exhibits 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 12 months—and these losses have proven to be dashing up over time. The ice comprises sufficient water to lift international sea ranges by 24 toes if all of it melted. The 12 months 2021 marked the twenty fifth 12 months in a row through which the ice sheet misplaced extra mass through the melting season than it gained through the winter.
Heat air temperatures trigger melting to happen on the floor of the ice sheet, a course of that’s accountable for round half the ice Greenland loses annually. 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 elements of the ocean, warming the waters coming into contact with the ice and melting the glaciers even sooner.
In consequence, Greenland, researchers predict, might quickly start to look slightly 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 kind 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 residence; in the event that they had been all to unfold out, every Greenlander would have about 25 sq. miles to themselves.
The complete northeast of Greenland is one large nationwide park that was established in 1974. It’s the biggest 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 autos within the nation is simply round 20 miles lengthy), Greenland additionally has a few of the purest air on the earth. You may 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 anticipate. Colourful flowers, lush meadows and hardy crops spring up when the snow begins to soften and the summer season’s delicate winds blow. Our Expedition Leaders even information our company 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 delicate 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 bathroom 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 residence to 310 species of vascular crops, together with 15 endemic species. At present that quantity has jumped as much as practically 500 species and rising. Virtually all of Greenland’s native vegetation disappeared through the ice age; the present vegetation got here largely from North America.
How’s that? Nicely, a examine performed in Svalbard, an archipelago north of Norway with an analogous ecosystem as Greenland, discovered 1,019 seeds of 53 species clinging to simply 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 present, 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 at the moment develop solely in scattered plots within the far south.
Nonetheless, area 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 possibility. 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 information for numerous North American and European tree species’ very best habitat niches. Inside a century, they discovered, all 56 species of bushes and shrubs they examined would possible 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 approach to a newly hospitable patch of Greenland soil. However with tourism and common flights between continents, the crops will most certainly obtain some vital unintended colonization help. Greenlanders can even most certainly begin to plant bushes themselves, in the event that they consider they may now develop there.
“Folks usually plant utility and decorative crops the place they will develop,” Jens-Christian Svenning, a biologist at Aarhus College, states. “I consider 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 shall be much more vulnerable to launched species sooner or later than it’s at the moment,” he mentioned. “So if importing and planting species takes place with none management, this might result in nature growing in a really chaotic manner.”
Why Inexperienced Isn’t All the time Nice
Whereas “extra inexperienced” may appear like a win for the atmosphere, the potential shift from mossy tundra to towering forest would nearly actually push out a few of Greenland’s native plant and animal species.
On the flip aspect, new bushes could assist alleviate a few of 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 in the near past, the warming of the Arctic atmosphere 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 modifications. Kaleeraq Mathaeussen, for instance, has been fishing since he was 14 years outdated. Like different locals, he has noticed large modifications round him that may’t be ignored. Prior to now, 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 apprehensive once I began to note that the ice barrier was getting weaker. At present 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 hand over this conventional transportation technique.
“There’s some detrimental issues. There are additionally some optimistic issues,” Mathaeussen states. He explains that in some methods, Arctic life has develop into simpler. For example, vitamins from glacial meltwater are enriching marine life, and with the hotter climate, it’s now potential to fish year-round by boat. Halibut fetch a excessive worth, and fishermen like Mathaeussen at the moment are financially higher off as a result of they will fish for an extended season.

Expertise Greenland Local weather and Tradition Up Shut
With all of those modifications occurring comparatively rapidly, the time to go to Greenland is now. On Nat Hab’s East Greenland Arctic Journey, vacationers have the possibility 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 journey from camp. Most guests by no means get to those distant communities, however our in a single day stays enable us to satisfy the native Greenlandic Inuit, study their tradition and traditions, and acquire an appreciation for the challenges and rewards of life in a quickly altering fashionable Greenland.
Think about an upcoming Nat Hab journey to Greenland as the proper place to unplug, join with nature, and see for your self the impression of local weather change within the Arctic.
