What their charts clearly show is that "nothing climatically unusual is happening."
In the chart below from a study by Polovodova et al, we see that 20th century warming is perfectly normal in a long-term historical context. It was no warmer – indeed, is slightly cooler – than either the Roman Warm Period or the Medieval Warming Period.
What we also learn from the papers is that these warming periods were global – not, as alarmists like to claim to support their scaremongering thesis, local:
A number of strident global warming scientists prefer to dismiss the significance of Europe's temperature record, claiming that it is local in nature and does not tell us what is really happening globally. However, other papers fully contradict this. For example, a paper by Wündsch et al., 2018 shows us that the warming today in South Africa also is nothing unusual.
