The results look very different for recent history. Both studies show that the warmest period of the last 2, years was most likely in the 20th century. They also show that this was the case for more than 98 percent of the surface of the Earth. This shows — once again — that modern climate change cannot be explained by random fluctuations, but by anthropogenic emissions of CO2 and other greenhouse gases.
And the speed of global warming has never been as high as it is today.

This press release was first published on the University of Bern website. Climate Warming is Unprecedented in Past 2, Years. New research has found that in contrast to pre-industrial climate fluctuations, current anthropogenic climate change is occurring across the whole world at the same time. In addition, the speed of global warming is higher than it has been in at least 2, years.

The warm period which became known as the 'Medieval Warm Period' in Europe and North America was not a global phenomenon; the warmest year period between the years and occurred at different times in different regions. The cold period which became known as the 'Little Ice Age' in Europe and North America was not a global phenomenon; the coldest year period of the last millennium occurred at different times in different regions. In red are the periods each across 51 years in which the reconstructed temperatures increased.
Global temperatures decreased in the periods in blue.
The green line shows that the maximum expected warming rate without anthropogenic influence is just under 0. Climate models dashed orange line simulate this natural upper limit very well. At more than 1. Instrumental measurements since in black confirm these figures.
