Enig i det. Men spørsmålet er likevel  : På hvilken måte justerer man rådataene for DTR. Det synes å være en annen metode for data før 1950 i forhold til senere. Men jeg skjønte ikke metoden.

Det synes temmelig klart at årsaksforholdene er temmelig sammensatte. UHI problematikken skulle være enkel å utelukke, det finnes jo en rekke værstasjoner som ikke har dette problemet. Og antallet av disse øker, Met har for lengst begynt å etablere rene klimastasjoner som er satt opp på steder der en kan utelukke UHI og annen forurensning. Jeg mener NOAA har gjort det samme.


Det er nettopp det Soon et al. har gjort.

Usikker på om det er informert om denne her tidligere.

Oscillations of the baseline of solar magnetic field and solar irradiance on a millennial timescale

Abstract
Recently discovered long-term oscillations of the solar background magnetic field associated with double dynamo waves generated in inner and outer layers of the Sun indicate that the solar activity is heading in the next three decades (2019–2055) to a Modern grand minimum similar to Maunder one. On the other hand, a reconstruction of solar total irradiance suggests that since the Maunder minimum there is an increase in the cycle-averaged total solar irradiance (TSI) by a value of about 1–1.5 Wm−2 closely correlated with an increase of the baseline (average) terrestrial temperature. In order to understand these two opposite trends, we calculated the double dynamo summary curve of magnetic field variations backward one hundred thousand years allowing us to confirm strong oscillations of solar activity in regular (11 year) and recently reported grand (350–400 year) solar cycles caused by actions of the double solar dynamo. In addition, oscillations of the baseline (zero-line) of magnetic field with a period of 1950 ± 95 years (a super-grand cycle) are discovered by applying a running averaging filter to suppress large-scale oscillations of 11 year cycles. Latest minimum of the baseline oscillations is found to coincide with the grand solar minimum (the Maunder minimum) occurred before the current super-grand cycle start. Since then the baseline magnitude became slowly increasing towards its maximum at 2600 to be followed by its decrease and minimum at ~3700. These oscillations of the baseline solar magnetic field are found associated with a long-term solar inertial motion about the barycenter of the solar system and closely linked to an increase of solar irradiance and terrestrial temperature in the past two centuries. This trend is anticipated to continue in the next six centuries that can lead to a further natural increase of the terrestrial temperature by more than 2.5 °C by 2600.

Altså TSI øking på 1 - 1,5 W/m2 siden Maunder minimum (Lille Istid), mens IPCC oppgir 0,1 W/m2.  Taler for seg selv.
