Advocates of the dangerous manmade global warming hypothesis call for regulations in response to their alarm. Assume for a moment that the alarmists’ feverish scenarios really were going to come to pass… would regulations make the situation better?
The Iron Law of Regulation suggests otherwise. For a new site from Kesten Green and Scott Armstrong that is devoted to experimental evidence on the effects of regulations, see IronLawofRegulation.com.
The May global average temperature was down by 0.16ºC from the previous month as the El Niño weather system weakened. The 0.55ºC May figure was nevertheless still warmer than the earlier, 2010, peak in temperatures. In other words, we have been experiencing the kinds of temperatures that the dangerous manmade warming alarmists have been warning would be harmful. We wonder how much additional net harm (i.e., after allowing for additional benefits) was caused by the warmer average temperatures over the last six or eight months?

The Heartland Institute’s Tenth International Conference on Climate Change (ICCC 10) took place in Washington D.C. on the 11th and 12th of June. Scott Armstrong presented a talk based on research with Kesten Green. Slides of their talk can be downloaded by clicking here. A flyer, summarising their evidence on climate forecasting, with links to relevant papers is available, here.
For this who missed the conference or would like to catch talks that they missed, videos of the ICCC 10 talks are now available online here. Scott gave his talk in a session with Anthony Watts and Roy Spencer. Video of their excellent session is here.
The benchmark global temperature data from the researchers at UAH-Huntsville have been adjusted to compensate for drifting in the positions of the satellites that take the readings and other improvements in the measurements and calculations. The improvements in the data series must be disconcerting for warming alarmists such as Mr Gore and the IPCC: dangerous warming and a “turning point” are nowhere to be seen. We hope they are relieved that there is (even less) reason to believe the Earth is in danger and that governments will realise the folly of policies to reduce carbon dioxide levels.
Our chart of The Bet to April 2015 is shown to the right of the page, as usual, using UAH’s revised series. The picture is clear, but for this who prefer numbers, here is a very small one: 0.000000000005. That number (which is roughly equal to 1-divided-by 214 billion) is the probability that temperatures would have equaled-or-exceeded Mr Gore and the IPCC’s 0.03°C per annum warming projection as few or fewer times as the 13-out-of-88 months of The Bet so far that they have done so… if their projection were unbiased.
For more information on the UAH data revisions, see the description by Spencer, Christy and Braswell, here.
The Italian newspaper La Stampa published an Alain Elkann Interview of Scott Armstrong on Sunday April 12 titled “J. Scott Armstrong: “Vi spiego perché le previsioni sul clima sono sbagliate”” here. Alain was particularly interested to know about the subject of theclimatebet.com: Professor Armstrong’s challenge to Al Gore to bet that temperatures will increase dangerously, as Mr Gore has threatened will happen.
Regular readers of this blog will be familiar with the Challenge, but for those of you who are not, or who are interested to read a fresh summary of what scientific forecasting tells us about 21st Century temperatures, you can find the full interview in English on Alain Elkann’s own site here. For those of you who have friends who are struggling to make sense of the dangerous manmade global warming alarm, the interview is a good place to start.
With 86 months of the 120 month Climate Bet behind us, we are still waiting for the “tipping point” Mr Gore promised us. We hope you haven’t been holding your breath, or planted bananas in your wheat field. While the actual temperature has been cooler than Professor Armstrong’ no-change forecasts for more than half of all bet months (51%), the Gore-IPCC forecasts ran hotter than the actual temperature for 81% of months to date.
In case you, and we, needed reminding, Christopher Booker describes the latest stories to break on the dubious adjustments and revisions that government agencies make to the sparse measured terrestrial temperature record in his The Telegraph article titled “The fiddling with temperature data is the biggest science scandal ever.” The adjusted data are used to derive the global average temperature series used by the IPCC and others who promote warming alarmism.
Reading Booker’s article leaves the reader with the impression that the use of the term “fiddling” in the title amounts to a classic case of British understatement. The term “rewriting history” is perhaps closer to summarising the violence that is still being done to the official temperature records.
A picture is sometimes worth a thousand words. Steven Goddard’s changing temperature history charts on this page of his blog very effectively illustrate some of the adjustments that have been made to the official series. It is possible, one might suppose, that better data might become available decades or even centuries after the event, or that better methods for analysing data might be developed. But such developments would not explain why every round of adjustments to the older data has resulted in a stronger warming trend.
The Institute of Public Affairs have published a collection of works on the physics, economics, and the politics of climate change (a.k.a. the alarm that dangerous manmade global warming is and will continue to occur.) The 21 chapters by leading researchers and commentators include Willie Soon’s “Sun shunned”, and Kesten Green and Scott Armstrong’s “Forecasting global climate change”. The book is available, here. We suggest sending Mr Gore a copy.
Update: Kindle versions of Climate Change: The Facts 2014 are now available on Amazon. Either search Amazon.com for the title or click the link to the book on your country’s Amazon site from the following list: US, UK, CA, AU, DE, FR, ES, IT, NL, JP, BR, MX, IN.
We imagine that Barbara Boxer will be particularly pleased that she did not respond to Professor Armstrong’s 2008 challenge to back her belief that the polar bear population was threatened with rapid decline by accepting his bet, based on scientific forecasting in Armstrong, Green, and Soon (2008), that polar bear numbers would remain at current levels or better.
It seems that modellers at the International Union for the Conservation of Nature agree with Armstrong, Green, and Soon that the models of polar bear biologist Steven Amstrup and colleagues, upon which Senator Boxer based her belief, are not fit for the purpose of forecasting the polar bear population. For more on this story see the article titled “Amstrup knows his polar bear predictions are flawed – but continues to promote them” on the polarbearscience.com site, here.
“There are no scientific forecasts of dangerous global warming” shouts a new article in the Financial Post. Readers of this blog know that already, but will likely want to read what the op-ed titled “Climate forecast: All’s well, despite what the IPCC says” by Kesten Green, Scott Armstrong, and Willie Soon has to say about the implications for government policy. It has already attracted lively discussion. The article is here.
The authors claim to provide the only scientific forecast of long-term climate, namely the naive no-change or no-trend forecast that is the basis of Professor Armstrong’s notional bet with Mr Gore. The forecast was originally published in 2009, and the International Journal of Forecasting article can be found here. The authors’ current working paper investigating possible improvements to climate forecasting for policy makers is here.
