PROOF FAKE NEWS: Antarctic turning green as global warming triggers moss explosion

From scientific paper in 2002 :

Green Island,Berthelot Islands,Grandidier Channel, Antarctic Peninsula, was originally designated as a Specially Protected Area through Recommendation IV-9 (1966, SPA No. 9) after a proposal by the United Kingdom.

It was designated on the grounds that the vegetation “is exceptionally rich, [and] is probably the most luxuriant anywhere on the west side of the Antarctic Peninsula”.

The Recommendation noted: “in some places the humus is 2 metres thick and that this area, being of outstanding scientific interest, should be protected because it is probably one of the most diverse Antarctic ecosystems”.

A Management Plan for the site was prepared by the United Kingdom and adopted through Recommendation XVI-6 (1991). The original reasons for designation were extended and elaborated, although following comparisons to other sites in the vicinity, Green Island was no longer considered to be particularly diverse.

The vegetation on the island was described as extensive on the north-facing slopes, with well-developed continuous banks of moss turf formed by Chorisodontium aciphyllum and Polytrichum strictum that, over much of their extent, overlie peat of more than one metre in depth.

Antarctic hair grass (Deschampsia antarctica), one of only two native vascular plants that grow south of 56°S, was noted as frequent in small patches near a blue-eyed cormorant (Phalacrocorax atriceps) colony.

The colony of blue-eyed cormorants, located on the steep, rocky northwestern corner of the island, was noted as being possibly one of the largest along the Antarctic Peninsula.

But the http://www.independent.co.uk/ reported,:

The Antarctic is turning green with rising temperatures having a “dramatic effect” on the growth of moss in the frozen continent, scientists have discovered.

Since 1950, temperatures in the Antarctic Peninsula have risen by about half a degree Celsius each decade – much faster than the global average.

And growth rates of moss after about 1950 have been running at four to five times the level before that year, according to a study by UK-based researchers who studied three sites across a 1,000km stretch of the peninsula.

Scientists are currently considering whether to formally adopt 1950 as the start of a new geological epoch called the Anthropocene because of the astonishing global effects that modern humans are having on the Earth.

In addition to climate change, the extinction of animal species, plastic waste – there could be more of that than fish in the sea by 2050 – ash from fossil fuels and radioactive particles from nuclear bomb tests will all leave a permanent record in the planet’s future rocks.

Researchers from Exeter and Cambridge universities and the British Antarctic Survey studied a 150-year period of moss growth in the Antarctic Peninsula by taking samples from the material laid down each year.

Dr Matt Amesbury, who took part in the study, told The Independent: “What we found were these large, dramatic changes occurring in all of our cores.

“On average, in terms of the growth rate of moss before and after 1950, there has been a four to five-fold increase in average growth rates.”

He added that change had kicked in at different times depending on the location between 1950 and 1980.

“Between 1950 and 2000 in the Antarctic Peninsula, temperatures increased by half a degree per decade on average,” said Dr Amesbury, of Exeter University.

“The reason we are so confident our mosses are responding primarily to temperature is because of the very wide-scale response we see in our moss banks … from three different sites 1,000km across the Antarctic Peninsula.”

The researchers, who reported the results of their study in an open-access paper in the journal Cell Biology, also looked into how sensitive the moss would be to further warming.

“The results of that analysis lead us to believe there will be a future ‘greening’ of the Antarctic and a further increase in moss growth rates.

“We are likely to see moss particularly colonising new areas of ice-free land created by the warmer climate … and particularly things like glacier retreat.”

However the Antarctic has a long way to go before its appearance is radically transformed.

“There is 0.34 per cent of the entire Antarctic continent that is predominantly ice-free,” Dr Amesbury said.

“Whilst we are talking about a greening and our results show quite strongly there is likely to be increased moss growth in terms of the rate and spatial coverage, as a whole the Antarctic will remain a white place for a long time to come.
