High Christmas temperatures cap off warmest year ever and spark climate change warnings

Bilbao, Valladolid or Pamplona started the year with record temperatures between 18 and 25 degrees in the month of January, which have survived so far. summer scenery The maximum temperature in the cities on these dates was around 10 degrees. With average temperatures above 15 degrees for the first time, it’s an alarming start to the year for meteorologists after 2022 kicked off as the warmest year in more than a century, according to the Meteorological Agency . It’s not an anomaly, but a trend: Four of the warmest years on record have occurred in the last seven.

The year that has just ended has broken all kinds of climate records in Spain and shows how the global climate is becoming more polarized every day with extreme temperatures and events. This does not happen only in Spain: as it was also the warmest year in neighboring countries France, Germany, ItalyUnited Kingdom, Switzerland, Austria and Ireland.

“2022 to be 1.7 degrees above normal This is a lot “The two-year record so far was 1 degree higher than the historical average,” explains Ruben Campos, a spokesman for AEMET. 1916. still, nothing like it was ever seen before in the last twelve months.

Probably the most impactful event of the year was the 42-day heat wave experienced in the summer, which was seven times higher than the average for the reference period between 1981 and 2010, and affected 40 million Spaniards. thermal shock to which the population was exposed 5,316 killed According to a recently published study by Aurelio Tobias (CSIC), Dominic Roy (University of Santiago de Compostela) and Carmen Iniguez (U. of Valencia), people due to extreme heat.

The temperature also severely affected the fauna and flora, especially on the east coast and the Balearic Islands. According to Manuel Vargas, an expert with the Mediterranean Group, the Mediterranean reached temperatures of more than 25 degrees and even 30 degrees on the water surface in the month of August, although the most serious problem is the gradual warming of the seabed. Is. Climate change.

,the ocean absorbs 90% of the heat It is caused by the greenhouse effect and its consequences are very serious. As the researchers point out, many living beings have adapted to specific conditions over thousands, hundreds of thousands and even millions of years and no longer have time to adapt. Mediterranean surface will warm at current rate up three degrees this centuryWhereas the underwater mass would be between 0.2 and 0.3 degrees, roughly a figure that could be enough to change currents and change ocean dynamics, although this is something that has not yet been sufficiently studied.

Beyond temperature, 2022 has left out other important statistics like devastating rainfall. The rains at the end of December have salvaged the situation to some extent and the year will end between the sixth and eighth droughts Since 1961, final data for the last three days of the month is pending. “Despite these December rains, which have been quite abundant, Spain ends the year 2022 in normal conditions of meteorological drought,” explains Campos.

The agricultural sector has been the one that has suffered the most from the water shortage and cuts in irrigation have resulted in many crops growing with less vigour. Now the farm is waiting for rainfall for the rest of the winter and spring, as that will determine how much they will be able to plant and harvest this year. The reserve of the reservoir at this time is 46% as against 55% which it usually holds on these dates as per the average of last ten years.

They confirm from the Meteorological Agency that it is very difficult to predict what will happen with the rain this winter because the models are contradicting each other and they don’t even have a forecast for the month of January. “What seems clear is that temperatures are going to be above normal winter averages, so the 2022 mark continues,” says Campos.

It is also unknown whether there will be a repeat of the terrible summer of 2022. Nevertheless, a progressive increase in temperatures due to the greenhouse effect will mean that what happened last year will become the norm, as AEMET advanced into September. Report good. Meteorologists estimate that every summer after the year 2040 they will be same as in 2022or even hotter.

Regarding the Mediterranean, Manuel Vargas cannot predict what will happen this year, but he confirms that if the current rate of ocean warming continues – as is expected due to CO₂ emissions – its water level and will increase even more. salinity and endangering the lives of the fish. At the same time, sea levels will continue to rise, not only because of the melting of the poles, but because of the heat that causes water to expand, he explains.
