Re: Heartland Institute - denial machine
Denialists of global climate change should read this. Invasive species are taking hold in warmer climate. I am sure there is research that shows if these alien species ever were detected in furthest northern areas of their natural habitats? This alone can put an end to all this controversy to me, but to the denialists should be an extra nail in the coffin.
Alien invaders threaten Antarctic fringes
The fringes of Antarctica are being invaded by alien plants and tiny animals, scientists have found. Researchers scoured the clothes and boots of tourists and scientists visiting the continent and found that most were carrying plant seeds. Alien plants already grow on the fast-warming Antarctic Peninsula.
Writing in Proceedings of the National Academy of Sciences (PNAS), the team says the plants are likely to spread as the climate warms. "People in the past have been sceptical, saying, 'It's largely ice-covered so it's unlikely that plants will establish themselves'," said lead researcher Steven Chown from Stellenbosch University in South Africa. "[They're] forgetting that probably less than 1%, but still a significant area, is ice-free - some of that's in the peninsula region, and it's been warming very quickly."
The Antarctic Peninsula, which runs up towards the southern tip of South America, has warmed by about 3C over half a century, much faster than the global average. As a result, ice cover is dwindling.http://www.bbc.co.uk/news/science-environment-17258799
