Consultant geologist Dr Geoff Derrick was invited to present this talk to a conference held in Brisbane at the Pullman Hotel, 22-23 July 2019. The conference was organised and hosted by DANA, a New Zealand-based group of Forest Industry Advisors. The conference was titled “Innovations in the Australian Forest Industry Sector”, and featured 2 days of lectures and workshop discussion, followed by a half-day field trip to Woodchip export facilities at the Port of Brisbane.
Here is a screen cap of the PowerPoint presentation, which has about 100 slides and was scheduled for about a half-hour from 5 to 5.30pm.
Neither Geoff nor DANA quite knew what to expect, both of the subject matter of the talk, and the disposition of DANA clients towards the talk. Prior to the conference, DANA received some feedback from forestry personnel as to whether the talk was appropriate for the conference, the implication being that it was likely to be sceptical in nature and therefore possibly off-limits for this group.
Undeterred by this reaction, and to their credit, the DANA organisers honoured the invitation and persisted with the presentation, but changed the time slot to the last talk on Day 1. A pdf of the talk is available from the DANA group (www.dana.co.nz; email: email@example.com) and from Saltbush.
The talk ranges widely over climate matters, from tree rings, warmist exaggerations, the science of CO2, the lack of sea level rise and the temperature record. It is not all-encompassing, with no discussion on subjects such as ocean acidification, the Great Barrier Reef, renewable energy etc etc. The entire talk is available as a pdf file of 21mb, and also as individual Sections 1 to 10, each a pdf of about 3-5mb. The section headings are listed below, and each section is introduced by a repeat of the title page of the talk.
The talk has been described as very professionally presented, with excellent data and a ‘must see’ for followers of the climate science debate. Being a presentation format but with no speaker involved, the reader here is invited to interpolate as to the full meaning of each slide, although most slides are considered largely self-explanatory. Some familiarity with the reading of graphs is assumed.
