The european summer is the warmest of the past 2,000 years

The greater part of Europe, during the last three decades, has experienced the hottest summers of the last couple of millennia, according to a new international scientific research with Greek participation. The highlight was the heat waves in the years 2003, 2010 and 2015.
The study of 45 scientists from 13 countries (and Greece), with coordinator professor Γιργκ Λουτερμπάχερ of the German University of Gissen, which was published in the journal environmental research “Environmental Research Letters”, was based on δενδροχρονολόγηση and analysis of historical data.
Among the researchers was professor-academician Christos Zerefos, and the Greek origin Elena Ξοπλάκη of the Department of Geography of the University of Γιούστους-Λίμπιγκ of Gissen.
According to the study, hot summers have existed during the Roman era, until the 3rd century ad.G., while between the 4th and 7th century. the european summers were colder.
The generally warm middle Ages followed by the cold Little Ice Age between the 13th and 18th century.
From the beginning of the 20th century, summers in Europe became gradually more strongly, mainly due to the anthropogenic activity that exacerbates climate change.
Over the last 30 years, european summers are warmer here, and 2,100 years ago, particularly in Southern Europe.
According to the study, between 1986-2015 in Europe during the summer months of June to August there has been an average increase of surrounding temperature on 1,3 degrees Celsius.
In addition, the heat waves tend to become more frequent, more intense and longer lasting. The study does not exclude that in the future heat waves may last even decades, according to the Athenian Agency.
In 2014, the Intergovernmental Panel on Climate Change noted that the period 1983-2012 was the warmest 30 years of the last 1,400 years old in the northern hemisphere (where it belongs and our country).
The new study goes even further back in time, to 138 p.X. It is noteworthy that the centuries before and after Christ’s birth were equally or slightly more warm than the 20th century, due to natural causes (increased solar radiation, changes in ocean currents, volcanic eruptions etc.).
