About Greg


Greg has been surrounded by ‘the bush’ all his life. When young his time was spent between the Blue Mountains, west of Sydney, NSW, Australia, and in the eastern suburbs of Sydney while his father worked at the University of NSW in high-energy physics. In Sydney he developed a love of the rocky shore, and would spend many hours snorkelling and fishing, while in the Blue Mountains his first playground was the national park that was at the end of the street. His expertise in plant identification started young, derived from a wanting to know what surrounded him in the mega-diverse Sydney region flora. Through this he developed (and when time allows, maintains) a keen interest in orchids, plants in the family Proteaceae and other families with strong Gondwanan links, and of course, photography.

Greg studied various biology and geology themes in undergraduate studies, culminating in an Honours B.Sc. degree where his honours project was the vegetation mapping of the remote, declared wilderness of the Kowmung Valley in the Southern Blue Mountains. He followed this with a post-graduate diploma in secondary science education. Later studies included work on the rare Hakea dohertyi, and a Masters in Environmental Management from the University of New England, Armidale.

Greg’s early career was in environmental education, working at Sydney Aquarium and also teaching high school science for almost 4 years, before being employed in 1994 as a botanist and environmental manager within NSW government departments – a career he is still undertaking. Greg has worked in environments as diverse as the Blue Mountains, the Macquarie Marshes, the North Coast and the Northern Tablelands and Western Slopes of NSW. Primarily working in vegetation mapping and environmental assessment, Greg has also found time to help his wife with raising their three kids, while living in towns throughout the northern half of NSW. In addition, Greg occasionally produces software titles on botanical themes under the self-publishing brand, Orkology.

Other significant web presences include the Panoramio pages (, where many of Greg’s photos are shown in geographic context.

Greg is a Threatened Species Officer with NSW Office of Environment and Heritage, Australia. His work as a professional ecologist and vegetation scientist takes him to some interesting parts of Australia’s east coast.

Climate models are fundamentally flawed as they greatly overestimate the temperature increases due to carbon dioxide.
There is empirical evidence to support this. I refer you to the large volume of papers in the scientific literature since the effect of 'heat trapping' by CO2 was identified by Svante Arrhenius in 1896 (see among other sources). If that still doesn't support your world view I would suggest any of the basic Physics courses at your local university would give you an understanding of why and how chemical bonds get to modify radiation (which after all, is what we are talking about - light and IR are merely forms of EM radiation), and then how that radiation is 'returned' (as a vibrating particle which we can call 'heat'). After you've dismissed that, I refer you to the close parallelling between the observed temperature rises (use a single, long-term station if you like, but statistically that is ludicrous) and the concentration of CO2 in the atmosphere. The two parallel each other so closely that there is no other explanation. Water vapour is a much more abundant greenhouse gas, and contributes more to the effect than anything else, but the difference between what we should be (a frozen slush ball in orbit) and the observed is largely due to the limited effect of CO2. On top of that, the difference between the depths of the last ice age and now is only a few degrees - and since the industrial revolution we have added as much CO2 again as existed during the last glacial based on the gas concentrations trapped in ice cores. Finally, in response to your earlier comment, the hottest years on record were 2005 and 2010, and the fallacy of the post-1998 'cooling trend' is a load of bull... All climate data needs to be reviewed in long timescales - 30 years is recommended for a minimum. A 7 - 10 year period allows too much inherent variation. As to the fact that there are in the order of 5 to 10 times as many 'new warmest' records being made as 'new coldest' then the trend must show towards warming.

John Hardy: My green school dream
Adrian What are your qualifications to be talking about anthropogenic global warming as a fallacy ad your fallacious belief that is CO2 is a plant food then more of it is good? (more H2O will kill you too!) Your profile is mysteriously absent from the link given above... I think you need to read some of the current journals and grey literature that is showing that while the CO2 enrichment effect is known and evident up to 400ppm (and dubious above that owing to the physiological constraints) that there is more limitation on plant growth and nutrient stress (particularly N) becomes evident quickly and the elevated temperature caused by CO2 and CH4 in the atmosphere (GH effect is proven for >100years) quickly causes water stress. Hence, plants don't grow any better when at higher CO2 (we are already >380ppm) and many will in fact wilt and die. Check the science and you will see your ideas are not as solid as you think.
