According to data from the Meteorological Service of Catalonia (SMC), collected since 1971 and published on the occasion of the agreement signed with the Center for Ecological Research and Forest Applications (CREAF-UAB) to study the relationship between phenology and climate change, fruit trees in Tarragona are blooming about 15 days earlier than 50 years ago, and the fruits are ripening one month earlier. In the specific case of pears, they are doing so 37 days earlier than five decades ago.
In the framework of this collaboration, the two centers will share and exploit data on specific plant and animal species and the changes they are experiencing over time. This includes those provided by the RitmeNatura.cat observatory, coordinated by CREAF since 2017, and those of the Xarxa Fenològica de Catalunya (Xarxa Fenocat).
As explained by Joan Pino, director of CREAF, professor of ecology at the UAB and one of the people responsible for RitmeNatura, the data collected by the SMC confirm that, for example, pears are ripening 37 days earlier than 50 years ago, and that apricots are arriving 28 days earlier.
All these phenological changes have been compiled at the municipality of La Serra d'Almos, Tarragona, thanks to the data recorded systematically by observer Josep Borrell for almost 50 years, and which have been published in the latest edition of the Annual Climate Indicators Bulletin of the SMC, with data from 1971 to 2018.
The director of the SMC, Eliseu Vilaclara, highlighted the high temperatures recorded this winter in Catalonia, specifically in the northern parts, where the average temperature in January 2020 has been up to 3 degrees Celsius higher than the average for this month between 1961 until 1990.
In December 2019, this anomaly was even more remarkable in the high mountains, where temperatures were up to 3.5 °C higher than usual. Also, this month of February has been the warmest on record at the Fabra Observatory in Barcelona since there have been official data (107 years).
