Man-made emissions will increase the global temperature by 1.5°C
If they tell us the temperature will rise 1.5°C because of increases in man-made emissions of carbon dioxide. Does this mean the global temperature should rise naturally by 48.5°C (1.5x97/3)? Utter nonsense!
They also deliberately forget the Little Ice Age (LIA) c1600-1750. Look at the world's longest running temperature record and see what you get. Oh, it was only the northern hemisphere they tell us, how do they know this? There is no accurate temperature or CO2 data from tree rings and ice cores to act as a reasonable reference.
Fig 2 Central England Temperature (CET) 1659-2020
The CET, the longest running temperature record in the world, shows natural warming coming out of the LIA of 0.03/decade, 1.08°C in 361 years. As this is natural warming it means;
From AR6 summary for policy makers, "A.1.3 The likely range of total human-caused global surface temperature increase from 1850-1900 to 2010-2019 is 0.8°C to 1.3°C, with a best estimate of 1.07°C", minus the 1.08°C natural, leaves -0.01°C cooling can be attributed to human-causes, clever eh!
Do they ever consider logic? What about, solar cycles, Milankovitch cycles, ENSO, PDO, AMO and others, These well known cycles operate in or out of phase of each other, in other words chaotic. They all affect the Earth's temperature both up and down to some extent?
And then there is magic stuff called water, in its three states; solid (high clouds, ice precipitation), liquid (lower clouds & rain/drizzle precipitation) and gas (water vapour) which they do not understand at all.
Now, let's have a look at the situation in Glasgow, the hosting city. For the last 23 years I have been collecting raw daily weather data (unhomogenised - "nae number fixin") for 28 locations in the UK, Glasgow airport (EGPF) is one. These data are from 48 x ½ hourly observation/per day for the last 8,402 days (403,296 individual observations), empirical data, "nane o the media single weather events or a few tree rings"!
