An International research team has discovered that seasonal temperatures in Europe, above all in winter, have been affected over the past 500 years by natural factors such as volcanic eruptions and solar activity, and by human activities such as the emission of greenhouse gases.
“The influence of the increase in levels of greenhouse gases, in particular, can be clearly seen since the end of the 17th Century”, Jesús Fidel González Rouco, a physicist at the Complutense University of Madrid and co-author of the study.
The international group that conducted the study included experts from the University of Edinburgh (UK), the Complutense University (Spain), the Justus-Liebig University Giesen (Germany) and the University of Berne (Switzerland).
