Evidence-based forecasting for climate change

April data after improved procedures: Chilling news for Mr Gore

without comments

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.

Why is the Arctic ice still there, Mr Gore? Another failed prediction

without comments

Al Gore predicted the Arctic ice cap would be gone by 2014 due to dangerous manmade global warming. The evidence is in: ice extent is up somewhat compared to the extent when satellite monitoring began in 1979. Professor Armstrong reminds readers of a May 20 article in The New American that there are no scientific forecasts that give credence to claims that dangerous global warming will occur. The article, titled “NASA’s own data discredits its predictions of Antarctic Doom”, is available here.

If Mr Gore really wants to make forecasts that are more accurate, he should learn the Golden Rule of Forecasting. By following the guidelines in the Golden Rule Checklist, he can avoid biased forecasting procedures that can cause forecasts to be less accurate than guessing. For more information on the Golden Rule, and to get a copy of the checklist of guidelines, see GoldenRuleofForecasting.com.

Climate consensus? What climate consensus?

without comments

An oft repeated climate forecasting claim is that 97% of scientists agree that there is a problem of dangerous manmade global warming and that human emissions of carbon dioxide must be drastically curtailed in order to avoid disastrous consequences. If that claim sounds unlikely to you, as well as being irrelevant, you are right. Professor Ross McKitrick—a scientific Toto to the climate-alarmist Wizard of Oz—dissects the claim and exposes its lack of substance in his May 11 article in the Financial Post titled, “The con in consensus“.

Cooling March follows February down

without comments

We have been slow to get the chart up for The Climate Bet results to March 2015. It is up now! Click on the thumbnail chart to the right for the full-sized image and data table. With the April global mean temperature reading only days away, will save our analysis and commentary until then.

Inquiry into global temperature data integrity announced

without comments

The London-based think-tank the Global Warming Policy Foundation  announced on 26 April 2015 a major inquiry into the integrity of the official global surface temperature records. Questions have been raised about the reliability of the surface temperature data and the extent to which apparent warming trends may be artefacts of adjustments made after the data are collected.

The inquiry will review the technical challenges in accurately measuring surface temperature, and will assess whether the adjustments to the data are biased and, if so, to what effect. For more information, or to make a submission, see here.

Doubt merchants, or truth warriors? Battle of the documentaries

without comments

Scott Armstrong was interviewed for the documentary, The Global Warming War. Released late last year, the movie provides a contrast with Merchants of Doubt in both style and substance. See The Global Warming War-Scott’s clips (2.5 minutes).

La Stampa interviews Armstrong on Gore bet

without comments

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.

Can’t fault the science? Attack the scientist

without comments

March 2015 saw a new low in public discourse about what changes, if any, to expect in climate over the 21st Century with The New York Times running a high-profile article attacking a scientist who is skeptical about the dangerous manmade global warming alarm. The article suggested that the scientist, Dr Willie Soon, should have provided information about his employing institution’s funding arrangements. Say what?

Was the article part of a larger investigation by NYTimes reporters that found that all scientists routinely report the details of their institutions’ funding, and any other arrangements or relationships that readers of their papers might find interesting… except Willie Soon? If they did, they must have forgotten to mention that in their article.

Is there any reason that Dr Soon was singled out for this “special” treatment, other than the unpopularity of his conclusions about the global warming alarm with the NYTimes reporters and their friends in alarm? We can’t think of any.

It appears that the alarmists are alarmed that the wider public are no longer alarmed. They have no response in science, and so resort to personal attacks.

In his recent article in The Washington Times, Professor Scott Armstrong challenges those who still fear global warming to test whether their fears are justified by following good scientific practice, and replicate the research that they find so unsettling. Perhaps their findings would be different. Now that would be a story!

Scott Armstrong’s Washington Times article, titled “Missing the mark on climate change skepticism: It’s not about the money, it’s about the science”, is available here.

86 months on, and still no “tipping point”

without comments

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.

January 2015 warms Mr Gore’s prospects

without comments

The global average average temperature anomaly ticked up a tad to reach 0.36°C in January, enough to get past half-way to the IPCC “dangerous warming” trend line that is standing in for Mr Gore’s bet. Mr Gore has now won 26 out of the 85 months of The Climate Bet so far; less than half of the 59 months that Professor Armstrong has won. We hope that Mr Gore wins a few more months to keep The Bet alive for the remaining nearly three years that are left to run.
