Part of the Northwest of the Region is among the areas where aridity has spread since the middle of the last century
Next autumn, which will begin on September 23, will be hotter than normal throughout Spain, especially on the Mediterranean side and the Balearic Islands. The State Meteorological Agency (Aemet) confirmed yesterday that this has been the warmest summer in Spain since the beginning of the series in 1961 and therefore in the 21st century. The next few months, the western Mediterranean may be within the 20% of the warmest of its climatology.
Seasonal predictions indicate that the Region of Murcia has up to a 70% chance of seeing its temperature increase in the next three months compared to the average. That is, it would be in the third of the upper value. For the rest of the Peninsula, the probability would be between 50% and 60%, according to the multi-model system of the Copernicus Climate Change Service. Likewise, the Northwest of the Region is among the areas where the arid climate has increased in the last 50 years, as well as other parts of Andalusia, Castilla-La Mancha, Extremadura and Aragón. Both temperature and aridity phenomena were shown yesterday in the report presented by the Aemet.
Warmer. Seasonal prediction of expected temperature (above or below the usual average) for October-December, made by the Copernicus Climate Change Service. In red, 60-70% upside probability. /
The general forecast of a drier autumn is not only a Spanish phenomenon. Higher temperatures than usual will be the dominant trend throughout Europe. “The response to the climate emergency is a serious and urgent matter,” said the Third Vice President and Minister of Ecological Transition, Teresa Ribera, who attended the presentation of the seasonal results of the Aemet.
Global warming
The forecasts also anticipate that this autumn there is a greater probability that there will be less rainfall than normal in the northwest of the peninsula, if the 1981-2010 period is taken as a reference. In addition, the predictions speak of a warmer season than is usual in the eastern Mediterranean.
More aridity. Changes in the Köppen-Geiger climate classification. In yellow, the areas whose climate was arid in the middle of the 20th century. In gray, the areas whose climate has since become arid. /
It is a proven fact that greenhouse gas emissions are causing an increase in global temperatures. In Spain, this warming is estimated at around 1.4ºC since the 1950s.
The clear increase in temperatures and the slight decrease in rainfall has resulted in an extension of arid climates in our country. It is estimated that, since the mid-20th century, arid-type climates have doubled in size in Spain, advancing at a rate of more than 1,500 square kilometers per year. This means that, every five years, an area equivalent to that of the province of Malaga acquires an arid climate in our country, to the detriment of temperate climates. Arid climates are related to less water availability for plants as a result of increased evaporation.
The Segura reservoirs are at 34% and continue to lose water
The reservoirs of the Segura hydrographic basin are at 34.3% of their capacity, which means a stock of 392 cubic hectometres of the 1,140 that the swamps of the demarcation can store. This figure represents a decrease of seven cubic hectometers with respect to the data collected last week, according to estimates provided by the Water Commissioner, dependent on the Segura Hydrographic Confederation (CHS). On the same date last year, the basin had 443 cubic hectometres.
