Reportedly, GISS does not process temperature data as they are determined but rather “corrects” them. Such adjustments could make sense, but to what extent they affect the warming trend remains an open question. Gavin Schmidt, the director and person in charge of the measurement series, recently tweeted some strange things:

He notes that the overall trend declines with the corrections (green vs. raw data (black dash). For now, however, there is a case for human influence on warming. only became noticeable after 1950.
If we now digitize this part of the overall series, a completely different picture emerges:
Although the trend is down from 1880 to 1950, for example, this is relatively insignificant for calculations of climate sensitivity, because very little human impact occurs during this time. .
However, after 1950 we see a 13% trend change due to the “correction”. This was also quickly communicated on Twitter and one has to wonder why Gavin Schmidt mentioned this irrelevant diminution in the original trends so prominently. Smoke screen?
