PRESENTATION TO THE 2014 GLOBAL BUSINESS FORUM
ASSESSING THE PROSPECTS FOR A BINDING, EFFECTIVE, GLOBAL CLIMATE TREATY
I was an invited speaker at the 2014 Global Business Forum in Banff, Alberta, September 18-19. I was asked to be on a panel discussing climate and energy policies. The format allowed me about 10 minutes to present my perspective on these issues to an audience of CEOs, business leaders, a few academics and other VIPs from Canada and around the world. I decided to eschew powerpoint and simply give a short speech, which is available here.

ME & THEOLOGY:
The Cornwall Alliance issued a Stewardship Statement in 2000 to which I was a signatory. They also prepared a document in 2006 for communication among religious groups, concerning the need to continue to prioritize development and poverty relief in the face of pressure for climate policies, to which I contributed economic input. Their 2009 statement on global warming has recently been brought to my attention a number of times on the basis of some loaded theological language and the appearance of a priori scientific assertions that ought properly to be matters of empirical determination. Though the signatories are not listed online I am apparently on the list. Reading the 2009 statement now I see a number of places where there is language I would not myself use, so I have indicated to the Cornwall Alliance (Sept 2014) that I am not now an endorser of that statement, and the list should be updated to reflect this.
As for what I actually think, on May 29 2012 I participated in a workshop at Huron College, University of Western Ontario, on exploring the theological and cultural assumptions for faith groups participating in the climate debate. My presentation was called "The Intrinsic Value of Nature and the Proper Stewardship of the Climate" and is available here.
THE ENVIRONMENTAL CRISIS: THE DEVIL IS IN THE LACK OF DETAILS
I spoke to a new organization called the Canadian Sustainable Use Network (CSUN) at its inaugural meeting, June 24 2014, at the School of Public Policy, University of Calgary. My talk focused on the need to stop thinking about the environment as one big abstract crisis and start seeing it as it really is, namely thousands of different issues, many of which aren't problems or which used ot be but aren't any more, and all of which exhibit their own complex aspects and attributes.
My presentation (powerpoint) is here. Partway into it I switched to a web browser to give the audience a guided tour of YourEnvironment.ca.
A BRIEF RETROSPECTIVE ON THE HOCKEY STICK:
In Spring 2014 I was invited to contribute a chapter to a forthcoming volume by the Institute for Policy Analysis in Australia on the subject of climate change. I was specifically asked if I would discuss the hockey stick episode, and it seemed an appropriate time to survey the story once again. Here is the result.
They wanted it fairly short, which meant it took much longer to write than if they'd asked for a long piece. Often I'd just be finishing the introduction and realize I'd hit the word limit. So naturally it doesn't provide an exhaustive treatment, but the reference list gives the reader plenty of additional leads. The book version is due out this fall and I hope you will consider supporting the project.
THE DOWNSIDE OF ENERGY CONSERVATION:
May 23 2014: A correspondent has asked me on Twitter what is the downside of energy conservation. Twitter being what it is, rather than try to go through all the reasoning in 160-character snippets, I have written up a 2-page note in reply. My thanks to @cswaine for the query.
I am very pleased to announce the launch of yourenvironment.ca, a new project of mine. The idea is very simple: to present the complete environmental record of every community across Canada. The site currently shows air emissions by source (back to 1985), air contaminant levels (back to 1974) and monthly average high temperatures (back to 1900) for hundreds of places across the country. Water pollution data are coming this summer.
The layout is self-explanatory and it's very easy to use. The data are all from government agencies, but most of it has not hitherto been disseminated in a usable form to the public. All my sources are, or will soon be, linked and the data I use will all be easily-downloadable.
So the next time you find yourself in a conversation with someone who (i) is convinced that Canada does nothing to protect the environment, or (ii) thinks winters around here used to be a lot colder/longer/snowier; or it never used to be this warm/cold in April/October/ etc, or (iii) worries/guffaws about the alleged/obvious ecological disaster all around us, and you wonder what, if any, of this is true, look at yourenvironment.ca and find out.
I especially hope households with high school students will learn about it, though from the experience at our home it might put some kids at risk of being expelled.
Journal Articles and Discussion Papers
A STATISTICALLY-ROBUST DEFINITION OF THE LENGTH OF THE GLOBAL WARMING PAUSE
I have published a paper proposing a definition of the length of the pause that is robust to autocorrelation and cherry-picking endpoints.
MODEL-OBSERVATION COMPARISON 1958-2012 IN THE TROPICAL TROPOSPHERE
Tim Vogelsang and I have published a paper in Environmetrics called
In it we compare the temperature trends in climate models over the 1958-2012 interval in the tropical troposphere to those observed in weather balloon data. The models tend not only to over-predict observed warming, but also to represent it differently. Models exhibit a relatively smooth upward trend, whereas observations show almost all the warming took place in a single jump in the late 1970s and the trend either side is practically and statistically zero. Since the tropical troposphere is where models predict the maximum response to GHG forcing should be observed, the absence of a significant trend there over a 55-year interval is a serious inconsistency. Data and code are here. A discussion at Climate Audit is here.
AVERAGE HOUSEHOLD SIZE AND THE DISAPPEARANCE OF MALARIA
I have completed a project with Finnish biologists Lena and Larry Hulden looking at explanatory factors for the pattern of malaria eradication around the world. We have found that declining average household size plays a big role, as does income. What doesn't play a role? Average temperature, among other things. We can't find any indication that a change in a country's climate will make malaria worse - in fact if anything, warmer temperatures are associated with less malaria, once the effects of income and household size are controlled for. The paper has just appeared in the Journal of the Royal Statistical Society.
A detailed but non-technical discussion is here.
The data/code archive is here (note the readme file).
