Otro invierno cálido ha hecho que algunas plantas florezcan antes de lo habitual. Según los registros de la Red de Observación Fenológica del Servicio Meteorológico de Cataluña (SMC), las fechas de primera floración en el sur de Cataluña se han ido adelantando desde 1970. Por ejemplo, algunas especies de almendros, como la variedad Ferragnes, florecen ahora 10 días antes que hace 40 años. ¿Cuál es la causa de que la primavera fenológica comience tan pronto?

Los expertos no tienen ninguna duda. «La temperatura media de Cataluña ha aumentado 1,5ºC desde 1950, y los cambios fenológicos a los que estamos asistiendo son una manifestación inequívoca de ello», afirma Marc Prohom, jefe del Departamento de Climatología del SMC.

¿Qué repercusiones puede tener que las plantas florezcan y los animales migren o salgan de la hibernación antes que en el pasado? Un problema potencial es la falta de sincronización entre las flores y los insectos que deben polinizarlas. Otro es que las heladas de marzo dañen las flores y los cultivos.

Con toda probabilidad, habrá un árbol, un arbusto o incluso un nido no muy lejos de ti que podrías vigilar semanalmente para ver cómo cambia (caída de hojas, floración, puesta de huevos, etc.). Registrando todas tus observaciones de forma particular y compartiéndolas a través de una plataforma de libre acceso, podrías hacer una contribución muy útil a la ciencia.

Barcelona has been the scene of several international events that have contributed to its consolidation, development and worldwide projection. The most relevant have been the Universal Exposition of 1888, the International Exposition of 1929, the 1992 Olympic Games and the Universal Forum of Cultures 2004. It is also the seat of the secretariat of the Union for the Mediterranean.[12] The origin of the name Barcelona is unknown.

The origin of the name Barcelona is unknown and there are several theories and legends that try to explain it. It is known that there was an original Iberian city of the Layetan tribe. It was later conquered by Cnaeus Cornelius Scipio Calvus,[14] and was later converted into a Roman colony, placed under the protection of Gaius Julius Caesar and Octavian Augustus, which received the name Colonia Iulia Augusta Paterna Faventia Barcino.[15] The name evolved during the Middle Ages, when the city was known by the names Barchinona, Barcalona, Barchelona, and Barchenona.

The coat of arms of Barcelona has its origin in the Middle Ages and appears for the first time, in the same disposition as the current one, in 1329.[19] The coat of arms is divided into four quarters where appear, in the first and fourth the cross of St. George in gules on silver, and in the second and third quarters with the condal/royal symbol of the four clubs in gules on gold. Numerous variants have also been found with one, two, three, or even five vertical bars in each quarter. The shield is headed by a crown, symbol of the sovereignty of the monarchs of the Crown of Aragon over the city.[20] The flag derives directly from the shield, so it has the same composition, although without the crown.
