From a global average anomaly of 0.71°C for April, temperatures dropped to 0.34°C for June 2016, two months later. The fall in average temperatures of 0.37°C is the largest two-month decline in the history of the Armstrong-Gore Climate Bet, and closely matches the record two-month increase of 0.38°C that occurred between December 2015 and February of this year.
Despite the rapid cooling, June was still relatively warm, and so the month counts as a win for Mr Gore. He needs temperatures to pick up again rapidly, and stay well up, if he is to have a chance of winning the bet, which ends at the end of next year.

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?

Last month we noted that if temperatures remained at around the same level as they averaged for the first three months of 2016, Mr Gore could win the Climate Bet. The figure—global average temperature anomaly—was +0.7°C.
We didn’t fancy his chances given that the figure is a high for the satellite record and is associated with a strong El Niño weather pattern. The warmth bringing El Niño weather pattern is followed by cooling La Niña weather. One month on, however, the April 2016 figure turned out to be +0.71°C. We imagine Mr Gore must be overjoyed!
With 20 months of the 10-year bet to go, we still don’t fancy Mr Gore’s chances that 0.7°C temperature anomalies will continue. We’ll keep you posted.
Here’s one: “Demographers agree almost unanimously… thirty years from now,… the entire world, with the exception of Western Europe, North America, and Australia, will be in famine”. (The “almost unanimously” claim might sound familiar to those who have been paying any attention to the media coverage of the current global warming alarm.)
If you’ve got the stomach for it, The Daily Caller provides a list of “7 enviro predictions from Earth Day 1970 that were just dead wrong”. That the alarming forecasts were so wrong should be of no surprise to anyone who is familiar with the Golden Rule of Forecasting, or with Kesten Green and Scott Armstrong’s study of analogies to the global warming alarm.
The Daily Caller article, available here, describes the forecasts and the very different outcomes. The directions of the errors is all in the same direction. A reasonable person might wonder if, in addition to ignorance of other aspects of good forecasting practice, bias played an important role.
While, after 99 months of the Climate Bet, Mr Gore’s forecast errors are 37% larger than Professor Armstrong’s, it is mathematically possible for Mr Gore to win. For that to happen, however, the global average temperature anomaly would have to stay around the average of the first three months of this year, +0.7°C. We will keep you posted!
We’ve had to adjust the Climate Bet chart to make room for the February 2016 UAH global average temperature anomaly of +0.83°C above the 1981-2010 average. For five months in a row now, Mr Gore and IPCC’s warming projection was more accurate than Professor Armstrong’s no-change-from-2007 forecast. The last time Mr Gore got such a run was in 2010, when the IPCC warming projection was more accurate for the first 10 months of the year.
Overall, however, the errors of IPPC projection are still as much as 40% larger than the errors from the evidence-based forecast of no change.
Mr Gore’s chances of winning the bet must, nevertheless, have improved with the latest figure. To put the data into perspective, if the temperature anomaly remained at or above .437°C for the last 22 months of The Bet—to the end of 2017—Mr Gore would win.
Perhaps Mr Gore will he change his mind and decide that he would like to put some of his own money at stake. He should be aware that the .437°C figure has only been equaled or beaten 7 times over the 98 months of The Global Warming Challenge to date, but that statistic will presumably carry little weight for those who, like Mr Gore, believe in the coming of a “tipping point”.

In a recent (12 February 2016) article, Willie Soon, David Legates, and Christopher Monckton revisited the topic of measuring global temperatures and explained why satellite measurements are superior to terrestrial thermometer measures. For readers who would like a refresher on why it is that The Global Warming challenge adopted satellite temperature data as the criterion for judging the outcome of the Armstrong-Gore climate bet, see the Soon, Legates, and Monckton article “What do we know about CO2 and global atmospheric temperatures”, here.
The prestigious Nature magazine on 24 February 2016 published online an article recognising the fact that (looking back) global average temperatures have been trend-less for at least the last 15 years. That’s right, Mr Gore, despite greatly increasing concentrations of atmospheric carbon dioxide, the various measures agree that there is still no tipping point!
David Whitehouse, in a 26 February article in the U.K.’s The Spectator, suggested that Nature‘s article “ought to have been front page news – and might have been, had it suggested that global warming was worse than we had thought.” Whitehouse’s article, with link to the Nature paper, is available here.
The UAH global average temperature anomaly spiked in January to the warmest it has been during the 97 months of the bet so far. We have seen similar spikes earlier in the bet period, in early 2010 and January 2013. All three of those spikes were (just) more than 0.3°C warmer than the 2007 annual average, which is the base year of the bet and the no-change forecast that Scott Armstrong is betting on.
The three spikes amounted to 5 months in all of temperatures more than 0.3°C warmer than the 2007 annual average.
A glance at the updated chart (right) shows that there have also been downward spikes in the UAH global average temperature during the period of the bet. In fact there have been six cool spikes amounting to 8 months of temperatures more than 0.3°C cooler than the 2007 annual average.
Not only have warm spikes been less frequent than cool spikes, in the context of the bet the cool spikes have been relatively cooler than the warm spikes have been warm. The average cool-spike temperature was .02°C cooler than the 2007 annual average than the average warm-spike temperature was warmer.
