New perspectives on temperature change
In each decade the monthly maxima and minima are plotted with a decadal mean, maxima and minima value.
But comparing the two decades also makes three things very clear. They are;
1 An increase in an annual mean temperature is sourced from changes that take place throughout the year, not just in the form of extreme mid summer temperatures as the climate mafia has encouraged the world to think.
3 Of the 12 monthly maximums and 12 monthly minimums that make up an annual mean temperature figure, only two, the midsummer months, pose any sort of risk of exceeding the values that the full suite of flora and fauna at any given location have already proven they can cope with.
This latter point is critical in the light of the Climate Mafia's continually repeated claim that small changes to the global mean temperature can have far reaching implications for the biosphere. As can be observed in the UK data sets, the rise in Autumn, Winter, Spring and Summer minimum temperatures, and the rise in Autumn, Winter and Spring maximum temperatures, poses zero to minimal threat to any of the flora and fauna species that have experienced those conditions. Indeed, in most cases this is an unambiguous benefit.
And even the threat from the higher midsummer maximums has been overstated for most of the planet. In the case of plant species there is no particular temperature at which an entire forest, species or genotype will suddenly collapse and die. The weaker individuals will die off first and their death will free up soil moisture and nutrients for the remaining ones. The end result will be a slightly lower density of vegetation cover with a slight compositional change in favour of grasses rather than trees in much the same way that composition changes with latitude and rainfall at present.
The same will apply with fauna. The weak will die off first as they already do in drought with a smaller core population that will then breed vigorously in response to the next cyclical change, as they have done for millennia. So next time you hear about "major implications" from minor changes in global mean temperatures, just walk the poor dears slowly through the monthly minimums and maximums that make up an annual mean temperature and ask them which species are put at risk by suffering through a mild winter.
