April 2018 temperatures show little change

without comments

Our update of the Whole-Earth Thermometer chart (to the upper right of this page) with the UAH April 2018 global mean temperatures shows temperatures were remarkably close to the 2007 Climate Bet base year average of 0.16°C.

The chart as a whole could reasonably be characterised as showing temperatures drifting sideways, largely within a +/-0.3°C band. Not surprisingly, then, the cumulative absolute error of the Gore/IPCC dangerous warming projection has been smaller than that of the no-trend forecast for only 2 of the 124 months of the bet so far, and that was back in September and October 2010.
