slippery ‘science’ found … Climategate 3.0

Sprung, Climategate 3.0 finds out that ‘paleo or dendro climate’ is not science but nonsense:

“The Team” members at UEA were warned that their tree ring interpretations were unsound

We now have what appears to be the first fruit of the ClimateGate 3 release of Warmist emails. Below is an email to Briffa and Jones from Don Keiller, a tree ring expert  — unlike anybody in The Team. Briffa did reply to Keiller but was so slippery that he enraged Keiller.  Subsequent emails to the one below are at the link

Dear Professor Briffa, my apologies for contacting you directly, particularly since I hear that you are unwell. However the recent release of tree ring data by CRU has prompted much discussion and indeed disquiet about the methodology and conclusions of a number of key papers by you and co-workers.

As an environmental plant physiologist, I have followed the long debate starting with Mann et al (1998) and through to Kaufman et al (2009). As time has progressed I have found myself more concerned with the whole scientific basis of dendroclimatology. In particular;

1) The appropriateness of the statistical analyses employed

2) The reliance on the same small datasets in these multiple studies

3) The concept of “teleconnection” by which certain trees respond to the “Global Temperature Field”, rather than local climate

4) The assumption that tree ring width and density are related to temperature in a linear manner.

Whilst I would not describe myself as an expert statistician, I do use inferential statistics routinely for both research and teaching and find difficulty in understanding the statistical rationale in these papers.

As a plant physiologist I can say without hesitation that points 3 and 4 do not agree with the accepted science. There is a saying that “extraordinary claims require extraordinary proof”. Given the scientific, political and economic importance of these papers, further detailed explanation is urgently required.

Yours sincerely, Dr. Don Keiller.

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.
