In the first two months of this meteorological year at my ten chosen weather stations, there were six instances of cooler temperatures and 14 warmer.
The five Northern Hemisphere Stations were, overall, 1.01°C warmer than the Ten Year Average (2008/9 to 20017/18).
The five Southern Hemisphere Stations were 1.18°C warmer.
“The literature” about present temperatures suggests varying amounts of global warmth above a notional Pre-Industrial Baseline. Initially, I was going to go for a low estimate (0.6°C) but decided on the middling 0.85°C instead. NASA is currently suggesting the world has warmed 0.9°C since 1880 so I am being conservative.
So, I have set my Pre-industrial Baseline at 0.85°C above the TenYear Average. The figure is calculated daily for graphing purposes. I have added 1.5°C to give the Paris Accord limit we should attempt to stay below if we are to avoid even more extreme weather events than those recently experienced.
At the 10 Weather Stations in the last two months, the Average Daily Temperatures are 0.25°C above the 10 Year running average figure, leaving us just 0.4°C “to play with” before the Paris Accord limit is passed.
There is no way of telling how representative my chosen Weather Stations are, among the thousands reporting to Weather Underground. It doesn’t seem to matter though. Over the next year or two, the trend to either “runaway greenhouse” or Grand Solar Minimum chill must, surely, become apparent.
Right now the record cold temperatures in the US Midwest are causing a stir. The extreme warming that is forecast to soon follow there will keep tongues wagging. In the southern hemisphere, Australia’s heatwaves are crossing the Tasman and washing over New Zealand.
The warmest of my 10 Stations was Koltsovo, last month, registering 3.65°C above Pre-Industrial. If the Siberian experience is replicated everywhere for a whole year we are all toast.
