Scientists using robotic ocean gliders to wander frigid Antarctic waters say they may have discovered a mechanism behind the melting of polar ice shelves – miniature submarine "storms" that are lobbing packets of warmer water toward the continent. The findings, published in the journal Nature Geoscience, shed light on the complicated currents that could potentially be contributing to the loss of West Antarctic ice:

BTO study says seabirds 'steer clear' of offshore wind farms
"Research by the British Trust for Ornithology and the University of the Highlands and Islands in Scotland, published this week, found most gannets would avoid even entering a wind farm area, while gulls do enter the area but then avoid flying near the spinning blades. The study, which was carried out on behalf of the Scottish government, suggested more than 99% of seabirds would change direction to avoid colliding with wind farms, although a small proportion would not."

Global warming 'doubles risk' of extreme weather - BBC News
"Extreme weather arising from a climate phenomenon in the Pacific Ocean will get much worse as the world warms, according to climate modelling. The study, in Nature Climate Change, adds to a growing body of evidence over climate change and extreme weather."

Climate change will hit Australia harder, CSIRO study says
"Australian science agency CSIRO and the Australian Bureau of Meteorology predict temperature rises of up to 5.1 Celcius in Australia by 2090 in their most comprehensive forecast yet. The report stated there was “very high confidence” that temperatures would rise across Australia throughout the century, with the average annual temperature set to be up to 1.3 Celcius warmer in 2030 compared with the average experienced between 1986 and 2005."

Australian fish moving south as climate changes, says study
University of Tasmania researchers have found 35 fish species face shifts in their ranges and egg-laying patterns as the waters off south-east Australia warm faster than average. The research, led by the University of Tasmania’s institute for marine and Antarctic studies, analysed the climate sensitivity of fish found off the south-east coast of Australia. The region is one of more than a dozen global ocean “hotspots” – others include off Brazil, in the Indian ocean and the North Sea – where the water is warming much faster than the global average for the world’s oceans."

1 in 6 species faces extinction due to climate change
"One in six of the planet’s species will be lost forever to extinction if world leaders fail to take action on climate change, according to a new analysis. The stark warning comes before nearly 200 governments meet for UN climate talks in Paris in an attempt to forge a global deal on cutting carbon emissions. Conservationists said such a large loss would be a tragedy with serious ramifications for people as well as ecosystems.
Creatures in South America, New Zealand and Australia will be hit much harder than in North America and Europe, due to a high number of endemic species. Relatively small land masses in New Zealand and Australia mean that many species there will be unable to migrate to cope with rising temperatures, found the study, published in the journal Science."

Re: Birds and wind farms/climate change
I meant to post this ages ago. Oops.
http://www.reviewjournal.com/news/scien ... ds-mid-air
I had heard of this some time before the article was written but wasn't sure how much truth there was in it. And the destruction of deserts and tortoise habitat is just unbelievable. Apparently there are often degraded sites that could be used, but the more natural sites are 'cheaper'. Once again big business takes low impact distributed generation and ruins it by scaling it up for their profit and control.

Wind turbines with owl wings could silently make more energy
"Moving silently through the air is not just for the birds. Wind farms inspired by the stealthy flight of owls could generate more energy without annoying those who live nearby, say researchers."

Curiously, no mention of what effect quieter turbines are likely to have on bird strike.

Re: Birds and wind farms/climate change
would it have more as the birds will not hear them so easily?
