Anomalies are used specifically to reduce issues. Using raw or absolute temperatures would cause greater error, due to weather and seasonality obscuring data (we’re not interested in whether December is colder than July for change in climate, but we’re interested in whether December 2021 is different to December 1991). It doesn’t affect the temperature increase, nor does it average the temperature over time (as you would have to with absolutes). It is a deference from the baseline, not an average. Of course interpolation is used between areas where stations don’t exist, but even if the whole globe was covered with weather stations, it would still make more sense to use anomalies for the ease of data processing and ability to show effect of climate.
It is more reliable than the raw temperatures, as such, yet you treat the use of anomalies as worse.
You can try and soothe yourself about talk of the poor, as if I don’t care, but it will be the world’s poorest who suffer from climate change, so I would easily counter it by saying we need to mitigate climate change for the sake of the poor. Any attempts to guilt me on this is the same sort of patronising, self-righteous piffle we get from many socialists on why their ideology is needed to be taken heed, and anyone who disagrees is a nasty Blairite/neoliberal/Tory.
