Our current temperatures are measured by instruments and the temperatures of the past are reconstructed based on proxies. Your chart picks up the temperature consideration starting at the coolest point of the temperature record in 10,000 years. This cold point was an anomaly from the normal range and the subsequent warming has been a blessing for all of mankind.
Using proxies is the only way to compare current to past. Proxy temperatures relate changes in terms far slower than instruments can record.
We are currently cooler than most of the Holocene period. IF we are to apply the instrument data to the proxy based graphs, then the instrument record becomes just on more data track to affect the average.
Over the course of the Holocene, proxies shown on the chart below indicate that the globe has been much, much warmer than now over just the last 10,000 years.
Other charts indicate that the globe was much, much warmer for much longer periods than the Holocene over the last half million years. In all cases, the globe cooled again when that interglacial ended.
Regarding the instrument record, from this layman's point of view, it is very suspect and relies heavily on averaging and projections prior to the satellite era. The number of stations per square mile north of the arctic circle are very few compared to the number of stations in New York City as an example.
Africa and Antarctica are also similarly under reported. Projections are employed to cover the lack of actual data. Outside of the important British colonies and the US, the climate data seems spotty or comparatively absent before 1930.
Basing real-world conclusion on this imagination-world set of data seems naively optimistic in the extreme.
Temperature variations during the Holocene from a collection of different reconstructions and their average. The most recent period is on the right, but the recent warming is not shown on the graph.
