About the Author

A Ph.D. in Ecosystem Dynamics from the Australian National University in 1992, then consultant to WHO, Parks and Wildlife, Land and Natural Resources services until moving to the San Diego Supercomputer Center at University of California San Diego in 1997. There I helped to develop computational and data intensive infrastructure for ecological niche modeling mainly using museum collections data with grants from the NSF, USGS and DOT. I developed the GARP (Genetic Algorithm for Rule-set Production) system making contributions modeling of invasive species, epidemiology of human diseases, the discovery of new species, and effects on species of climate change. Judged by the US Immigration Service as an Outstanding Researcher, a category for those recognized internationally as outstanding in their academic field.

    I’m sure you’ve heard about the latest CSIRO and BOM relesse “It is very likely that human activities have caused most of the global warming observed since 1950
    There is greater than 90% certainty that increases in greenhouse gas emissions have caused most of the global
    warming since the mid-20th century. International research shows that it is extremely unlikely that the observed
    warming could be explained by natural causes alone. Evidence of human influence has been detected in ocean
    warming, sea-level rise, continental-average temperatures, temperature extremes and wind patterns. CSIRO
    research has shown that higher greenhouse gas levels are likely to have caused about half of the winter rainfall
    reduction in south-west Western Australia.”

    what should I ask for so that their data can be checked by enthusiastic amateurs

    David, you posted in WUWT replying to my request (peter2108) for code saying ” I can send all the code if you want to contact me.” That sounds like a good idea but I can’t find a contact email anywhere on this site. My email is peter@monicol.co.uk.

    BTW the RSS feeds on the site don’t work on Google Chrome (but do on IE). The PDF links on this page (eg http://landshape.org/enm/wp-content/uploads/2009/06/ee-20-4_7-stockwell2.pdf) generate a 500 Error on both browsers – I was looking for a contact email

    Your Web site is haunted by warmist spies. I cannot download your PDF files or others because I get error messages when I click on the file name or on the highlighted PDF. They are of three types:

    500 server error
    404 server error

    You should complain to the owner of the site.

    New Judith Curry Interview Just Published: The IPCC May Have Outlived its Usefulness Dear Editor, I just wanted to send you a quick mail to let you know that we have conducted a very interesting interview with the well known climatologist Judith Curry.It’s a very balanced interview and I thought you and your readers may be interested in reading about Judith’s concerns for climate science, how climate change is affecting the planet, reasons for the increase in scepticism and why climate scientists have lost touch with the public. You can read the full interview at: http://oilprice.com/The-Environment/Global-Warming/The-IPCC-May-Have-Outlived-its-Usefulness-An-Interview-with-Judith-Curry.html Some of the questions we asked Judith are: Q. You have said in the past that you were troubled by the lack of cooperation between organizations studying climate change, and that you want to see more transparency with the data collected. How do you suggest we encourage/force transparency and collaboration?Q. Do you feel climatologists should be putting more effort into determining the effect of the sun on our climate? As the IPCC primarily focuses on CO2 as the cause of climate change – Is the importance of CO2 overestimated and the importance of the sun is underestimated?Q. What are your views on the idea that CO2 may not be a significant contributor to climate change? The full interview is at: http://oilprice.com/The-Environment/Global-Warming/The-IPCC-May-Have-Outlived-its-Usefulness-An-Interview-with-Judith-Curry.html I hope you find the interview interesting. Best regards, James Stafford

    Dear Editor, I hope you are well. I just wanted to send you a quick mail to let you know about some unique CO2 widgets we have created which you may be interested in using on your site. They are unlike anything else out there, are free to use and come in a variety of sizes and colours.You can see what is available at: http://oilprice.com/free-widgets (it’s the top widget) – there are also other CO2 and energy widgets you may like there. (all you have to do is take the code by the side of the widget and paste it in your source code.) If you have any questions on the widgets or would like something tailor made (again for free) please just let me know. Kind regards, James Stafford

    News Tip – The Limitless
    Potential of the E-Cat: An Interview with Andrea Rossi

    Dear
    Editor

    I wanted
    to get in touch as we were fortunate enough to interview the media shy Andrea
    Rossi, creator of the E-Cat this week and i thought you and your readers may be
    interested in hearing what he had to say.

    Mr.
    Rossi appears to have produced the first working “cold” fusion device, or low
    energy nuclear reaction (LENR), with his Energy Catalyser (E-Cat) machine. The
    E-Cat machine could provide almost limitless, clean, cheap energy and could
    prove to be one of the greatest inventions of all time.

    You can read the full interview at: http://oilprice.com/Interviews/The-Limitless-Potential-of-the-E-Cat-An-Interview-with-Andrea-Rossi.html

    It’s
    quite a long interview as Mr Rossi answered over 40
    questions.

    Some
    of the questions we asked Mr. Rossi take a look at:

    ·
    Why
    it took so long for him to go public with his
    discovery.

    · How the
    E-Cat will produce energy costing $10/megawatt hour.

    · When he
    will release more detailed information on the E-Cat.

    ·
    Why
    he believes international media coverage of the E-Cat has been so
    muted.

    ·
    His
    feelings towards critics and the scientific community.

    ·
    His
    manufacturing and distribution goals.

    · How the E-cat will
    help reduce mankind’s dependency on fossil fuels.

    · + Many
    more details on the e-cat, LENR and Rossi himself.

    The full
    interview is not available for publication – but we are happy for you to use
    excerpts with a link back to the source.

    The full interview is at: http://oilprice.com/Interviews/The-Limitless-Potential-of-the-E-Cat-An-Interview-with-Andrea-Rossi.html

    I hope you find the interview interesting.

    Dear David

    Thanks for your very informative blog, you have no idea how useful it is for some newbies like me who are dragged into ecological modelling. 
    I am just wondering to know you idea about “Ensemble models” introduced in ecological modelling?Do you agree on the way they they offer it?(I mean weighting methods or combination methods?

    All the best from Kiwiland

    New Bill McKibben Interview Just Published: Solving the
    Earth’s Climate Problems

     

    Dear Editor,

    I just wanted to send you a quick mail to let you know that we have conducted a
    very interesting interview with the well known environmentalist Bill McKibben.
    It’s an interesting interview and one I thought could work for your readers.

    You can read the full interview at: http://oilprice.com/Interviews/Solving-the-Earths-Climate-Problems-An-Interview-with-Bill-Mckibben.html

    Some of the topics Bill talks about are:

     

    • Why the West should fund the
    development of renewable energy in India and China.
    • How we can help solve the Earth’s climate problems.
    • Why Obama needs to step up his game.
    • Big oil’s success at keeping climate change out of the headlines.
    • Why he fears Keystone XL will shortly be pushed through.
    • Why we have to massively deploy clean energy technology Now!
    • His views on the Canadian oil sands.
    • The economic impact of a massive transition to renewables.

    The full interview is at: http://oilprice.com/Interviews/Solving-the-Earths-Climate-Problems-An-Interview-with-Bill-Mckibben.html

    I hope you find the interview interesting.
