competing headlines, warming or cooling … thriving or dying

Climate change pushing krill to the North? Or at least, activists would say that, without understanding the full story:

[…] All parties were enjoying the krill fishing; except perhaps the krill, some of whom foolishly took refuge in our net. Whereupon they were delivered into the clutches of another group of voracious seagoing mammals more commonly known as marine scientists. Just like the whales, the scientists were pretty excited to be catching large numbers of Euphausia superba this far north where in theory they should not be. Construction work on a new theory will commence as soon as the rubble from the old theory has been cleared away. This morning, we completed leg 9 and are taking a more south westerly course down towards the Antarctic Continent over the next few days.

The Aurora Australia is doing trawling and other scientific experiments all this month before returning to Mawson to relieve the summer crew. The Antarctic ice sheet has been growing in the last few decades, so I am not surprised krill moves north too. Maybe the title would be: Expanding Antarctic Ice-sheet moves Whale’s food North. Or Global Cooling expands Ice-sheet. At least they say, if the facts are wrong, you need to find a new theory.

Then, Professor Turney, the leader of the magical mystery tour stranding, now says icebergs killed off thousands of penguins.

Chris Turney: Penguins Don’t Migrate, they’re dying!

Guest essay by Eric Worrall Chris Turney, leader of the ill fated 2013/14 Ship of fools expedition to the Antarctic, which got stuck in the global warming while trying to retrace the Mawson Expedition, has been urging people to listen to his expert knowledge of Penguin colonies. More than 150,000 Adélie penguins have perished in…

Yeah sure Professor, pull the other one:

Not A Lot of People Know That

Headline News, Global Cooling confuses Penguins./sarc

The idea that global warming causes icebergs would be laughable if it had not come from a supposed scientist. But what is really interesting is this comment on the SMH web page:

I originally dismissed the comment as unverifiable, but on checking it turns out that David Killick is the official photographer, sent as part of a team of six to dig out one of the Mawson’s huts at Cape Dension. (See here)

Mawson, you may recall, was one of Australia’s most famous Antarctic explorers, who explored the region a century ago.

Also, the figures Killick quotes are correctly sourced from Turney’s own paper here. Clearly, if the figures are correct, there have been large variations in the Adelie population over the years. The idea that the recent decline is of any real significance is potty.

Killick’s criticism about making the count in just a day also appears valid. Stacey Adlard works for the British Antarctic Survey, and spends five months every year on Signy Island, part of the South Orkneys, doing little but count bird populations. Her blog is here.

 

Nature, unfortunately, is cruel, and there will always be local events which affect animal populations. But there is no evidence whatsoever that Adelie populations are in decline, or under any stress. […]

Turney, wrong still.

Update: Penguins thriving in East Antarctica

The AAD reported this research in October 2015 – Adélie penguin population almost doubles in East Antarctica. The SMH has just reported – Giant iceberg could wipe out Adélie penguin colony at Cape Denison, Antarctica

About Tom Harley

Amateur ecologist and horticulturalist and CEO of Kimberley Environmental Horticulture Inc. (Tom Harley) Kimberley Environmental Horticulture Incorporated Kimberley Environmental Horticulture (KEH) is a small group of committed individuals who promote the use of indigenous plants for the landscaping of parks and gardens. Rehabilitation of Kimberley coast, bushland and pastoral regions are also high on our agenda. This includes planting seedlings, weed control, damage from erosion or any other environmental matter that comes to our attention. We come from all walks of life, from Professionals and Trades oriented occupations, Pensioners and Students, Public Servants and the Unemployed. We have a community plant nursery where we trial many old and new species, with a view to incorporating these into our landscaping trials. Our labour force are mainly volunteers, but with considerable help from the 'work for the dole' program, Indigenous Community Development Employment Program (CDEP) groups and the Ministry of Justice, with their community work orders; in this way we manage to train many people in the horticultural skills needed for indigenous plant growing. We constantly undertake field trips that cover seed and plant collection in the Kimberley. Networking around the Kimberley region and the east Pilbara is a necessary part of promoting our activities. We consult on a range of Environmental and Landscaping matters that deal with our region. Our activities involve improving Broome's residential streetscapes by including 'waterwise' priciples in planting out nature strips. Sustainable environmental horticulture is practised by members of our group. We use existing vegetation as the backbone of any plantings, using these species to advantage when planning to develop tree forms or orchards. The Broome region is sensitive to development. Subsequently many weed species have become dominant in and around developed areas. The use and movement of heavy machinery is the biggest single cause of environmental degradation. We dont live in a 'Tropical Paradise' but on the edge of the Great Sandy Desert. The plants that survive best here, grow in well-drained pindan sand, and are found from the Dampier Peninsular southward to where average rainfall is below 600mm. When we use rainforest species, detail is important when planting, water catchment, sunlight and understorey species are all considered. The use of recycled 'grey' water is an advantage here as well as treated waste-water, although many local species do not fare well with nutrients from this source. We use waterwise planting methods which include harvesting asmuch rainwater as possible, with swales designed to hold up to 200 litres, to help recharge the local groundwater aquifer. There has been a serious decline in this aquifer over the last few years. With the fast expansion of the Broome peninsular, more and more land is being covered by concrete, iron and bitumen so that much less water is available to replenish the aquifer, allowing the salt content to become significantly higher. The small Broome Peninsular is on the south-western corner of the Dampier Peninsular (bound by Broome, Derby and Cape Leveque at the northern tip). Compaction by vehicles also inhibits water retention due to the content of our local pindan sand, hard as concrete in the dry, going to soft and sloppy mud after rain. None of us are botanists, inevitably we have got some names wrong, names changed, or have not gone to sub-species level.
