While the Arctic is usually thought of as a vast, desolate landscape of ice, it is in fact home to hundreds of species of low-lying shrubs, grasses and other plants that play a critical role in carbon cycling and energy balance.
Now, Arctic experts have discovered that the effects of climate change are behind an increase in plant height across the tundra over the past 30 years.
As well as the Arctic's native plants growing in stature, in the southern reaches of the Arctic taller species of plants are spreading across the tundra. Vernal sweetgrass, which is common in lowland Europe, has now moved in to sites in Iceland and Sweden.
Dr Isla Myers-Smith of the School of Geosciences at the University of Edinburgh, and Dr Anne Bjorkman from the Wankenberg Biodiversity and Climate Research Centre (WiK-F) in Frankfurt, led the international team of 130 scientists in the Natural Environment Research Council (NERC)-funded project.
More than 60,000 data observations from hundreds of sites across the Arctic and alpine tundra were analysed to produce the findings, which were published in Nature today.
Dr Bjorkman said: "Rapid climate warming in the Arctic and alpine regions is driving changes in the structure and composition of plant communities, with important consequences for how this vast and sensitive ecosystem functions.
"Arctic regions have long been a focus for climate change research, as the permafrost lying under the northern latitudes contains 30 to 50 percent of the world's soil carbon.
"Taller plants trap more snow, which insulates the underlying soil and prevents it from freezing as quickly in winter.
"An increase in taller plants could speed up the thawing of this frozen carbon bank, and lead to an increase in the release of greenhouse gases.

Do taller plants consume more co2 than short plants?
Seems like God’s creation is doing something to take care of itself.
California Redwoods went there to escape California tax rates.
Nothing a saturation of Roundup® wouldn’t cure.
#1 - How do plants “move” ? This is something I never learned in School ,
#2 - Because of increases in human activity in the
Arctic over the past 50 years there is an increase in plant seed distribution, by human interference .
#3 - Over the past 50 years Vehicles have deposited seeds which were attached and carried in from lower terrain.
So...the trees are migrating? Are they illegal alien trees?
The Scott expedition ran into devastating rain that turned everything into a clinging muddy nightmare.
They don't show the video footage of that in grade school any more?
There are no true educated Scotsmen.
I wonder if it was glow-bull warming that made Sahara into a desert...
“#1 - How do plants “move” ? This is something I never learned in School “
Have you not seen the movie THE DAY OF THE TRIFFIDS? =)
But they also say that it's been many,many years since that glacier disappeared.
Was the internal combustion engine responsible for that disappearance?
The arctic has been warming for 13,500 years, since the end of the last ice age, sometimes called the Kansan, as the ice sheet was up to 4 kilometers thick as far south as Kansas. Farmers in the upper midwest have to clear large rocks out of their fields every spring, coming up out of the soil due to “rebound”, still recovering from the massive pressure the ice sheet exerted. The only end to “global warning” will be the onsite of the next Ice Age, which is overdue.
Are they using a professional van line or merely renting a U-Haul?
This strikes me as a good thing. Why despair over an area growing more hospitable?
Many parts of Texas, you can deep till a piece of land and sunflowers will grow in place as well as weeds you did not know you had.
Clearing land of mesquites and juniper can also results in a sunflowe crop...the seeds were already there.
That’s a good thing. Plants suck up CO2. Global warming solved. Wise God we have.
This is dangerous for people. Once those plants reach sufficient height polar bears can hide behind them.
good movie
OMG OMG !!!!!!
And white bears coats are shifting to brown !!!! OH THE HUMANITY.
Nothing you will be hearing from Algore, the scientific moron (of ‘the debate is over’ fame), as he flies to another global warming party/meeting and burns more carbon than 1000 other citizens.
