Although we’ve already been in fall for several weeks, there are days when the temperatures we’d all hope to enjoy barely feel there. And it only reflects the fact that summer is becoming more and more pigeonholed and begs us to sacrifice ourselves to allow us to enter the next season. And we’re not wrong, since AEMET indicates that summers in Spain have been getting longer at a rate of 10 days per decade since the 80s.
Spring one. We think that summer is equally long, pushing spring and autumn equally. Popular culture has successfully coined the term “summer” to describe these short-sleeve Octobers, but climate data reveals that the season’s real devourer works ahead, since summer mainly invades spring.
Here we have an analysis with 44 weather stations between 1971 and 2018 that shows us that the start of summer is advancing at an average rate of 6.76 days per decade and its end is being delayed at a rate of 2.74 days per decade.
his explanation. With this information in hand, we can see that summer moves into May and June with twice the aggressiveness it enters autumn. In fact, the most updated reports from AEMET confirm that the so-called “spring” has already crossed the thirty-day invasion of various parts of the central-northern peninsula.
But, for his part, Autumn resists the challenge better. The backward extension of summer is small and only statistically clear on the Cantabrian and Mediterranean coasts, where heat has increased by about two or three weeks in global calculations in recent decades. In the western half of the peninsula, this autumn extension rarely lasts more than a week.
At two speeds. What this transformation really means is that the geography of heat is changing the physiology of our country, and it does not do so uniformly, since there is no homogeneous climate change. And here the data paints a map of extreme regional disparities, with the Pyrenees and peninsular northeast areas the biggest victims of this summer’s expansion. The La Molina observatory is the best example of this mutation, since between 1979 and 2000 it recorded 49 days of clear summer heat, but this number increased to 69 days in the last quarter of a century.
In contrast, to the south of the peninsula, large areas of the Cantabrian coast and Galicia show much more stable summer figures. Extreme heat certainly has a strong effect there, but the duration of the summer season does not extend with the same intensity as in the northern mountain systems.
in the future It’s not something we’ve seen now, but starting in 1979 the global warming engine revved up, imposing this accelerated rate of warming we’re experiencing today. But a study looking to the future has been published Geophysical Research Letters It has already been warned that if emissions are not drastically mitigated in the Northern Hemisphere, summers lasting about six months could become the new climate normal by 2100.
