fixing agendas …

BoM’s practices of data adjusting to suit an agenda, are seriously unraveled by Dr Jennifer Marohasy in an Online Opinion article today. Pointing out some rather large alterations to a rural site that hasn’t had any changes in 100 years or so can cause major problems when the science of bushfires and climate change are studied.

How hot was it at Rutherglen on Black Friday? Black Friday was that tragic day – 13 January 1939 – when a firestorm swept across Victoria destroying whole towns.

Just to the north, at Rutherglen, did maximum temperatures reach 47.6 °C on that fateful day – or only 42.2 °C? Experts will explain that when considering the likely impact of future bushfires, it is important to consider the historical temperature record – but which record? The Australian Bureau of Meteorology keeps two records: there is the official ACORN-SAT record used to report on climate change each year and easily accessible at their website through an interactive map; and then there are the raw values in a back cupboard – metaphorically speaking. […]

Dr Marohasy has found a number of ridiculous assumptions for BoM adjusting carefully measured temperature data. Read it all.

Now, another Government Department in West Australia, the Water Corporation is having similar data problems with rainfall and dam data, in work being done by Warwick Hughes. It appears recording rainfall and encouraging water run-off into dams has all become too difficult. Lets hope this can be straightened out with Warrick Hughes’  diligent auditing Read all the comments of explanations into the mess here.

[…] They must release all their daily rain data so various sources can be compared. On 2nd August I posted – Perth dams rain data is in need of an audit. On 2nd May I posted – West Australian Govt Water Corporation fails to record March 2016 rain at several dams.

Their instruments are away for repairs? For months? Imminent rain:rainAnother science furphy was the demise, so called, of 95 % of the Great Barrier Reef. They stuffed that one up, too:

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.
