The storm ‘Filomena’ leaves the lowest temperature ever recorded in the Iberian Peninsula: –34.1C
Temperatures in Spain this winter are reaching maximum levels. This week has been very cold, with frosts in much of Spain even in areas very close to the coast. The early morning of this Wednesday was marked by intense cold and snowfall. The thermometers show such low figures that the temperature at the Clot de la Llança (Alto Aneu) weather station stands out: – 34.1 degrees.
It is the lowest temperature in the Iberian Peninsula since there are records. Information provided by the Parc Natural de l’Alt Pirineu (managed by Meteo Pirineo and Meteo Valls d’Àneu). And it has also been confirmed by AEMET. This temperature, 34.1 degrees below zero, is a record since the last time something similar was recorded was on February 2, 1956 with -32.0ºC in Estany-Gento, in the province of Lleida,

Inland waters such as rivers, lakes, and reservoirs play an important role in the global carbon cycle.
Calculations that scale up the carbon dioxide emissions from land and water surface areas do not take account of inland waters that dry out intermittently.
This means that the actual emissions from inland waters have been significantly underestimated—as shown by the results of a recent international research project led by scientists at the Helmholtz Centre for Environmental Research (UFZ) in Magdeburg and the Catalan Institute for Water Research (ICRA).
The study was published in Nature Communications.
“The interaction of local conditions like temperature, moisture, and the organic matter content of the sediments is crucial, and it has a bigger influence than regional climate conditions,” Keller explains.
So what do the results of the study mean for the future assessment of carbon dioxide emissions from inland waters? “Our study shows that carbon dioxide emissions from inland waters have been significantly underestimated up until now,” says Koschorreck.

Following Spain’s weekend of surprise early-season-snow, ORANGE ALERTS have now been issued across the country as the prospect of yet more severe wintry-weather looms — residents have been urged to prepare.
Spain’s state weather agency AEMET had predicted last weekend’s “polar front” and subsequently placed parts of Mallorca and Menorca on orange alert. Now though, an additional 33 provinces have been placed under winter-weather alerts across the country -from Lugo in the north, to Malaga in the south- as further Arctic plunges appear set to engulf ALL of Western/Southwestern Europe this week.
A staggering 40 cm (15.8 inches) of snow buried Northern Spain’s ski resorts over the weekend, including Fuentes de Invierno, in Asturias — as reported by murciatoday.com.
Snow also fell in more unexpected areas, like Port de Pollenca — a small town in Northern Majorca.

Regional differences regarding other reconstructions
The results of the study show a temperature rise in the beginning of the Holocene, reaching the highest values in the Holocene Climate Optimum (about 7,800 years ago). There are also high temperatures until about 6,000 years ago, when a decline of temperature started and led to the lowest values in the first stage of the late Holocene (about 4,200 and 2,000 years ago).
Last, researchers detected a rise of temperatures over the two last millenniums, but they state they have to be careful with these data. “We cannot guarantee the observed rise in the reconstruction results from a temperature rise only, we cannot rule out other variables that can influence at other levels, such as the gradual increase of the anthropic activity in the area, which can change the community of Chironomidae to species that adapt to higher temperatures, but there are also human influence indicators,” says Narcís Prat.
Although these conclusions can coincide with other paleoclimate reconstructions, results also highlight some divergences at a regional level. “These differences can occur due the fact that some indicators point out to different seasonal signs. Therefore, Chironomidae are indicators of temperature in summer, while others such as chrysophites or alkenones are related to winter/spring temperatures,” notes the researcher.
A tool to evaluate climate trends

In Spain, has been following my lead on the poor quality of weather stations that produce record-high temperatures. I recently pointed out how the tentative all time high temperature in Africa could very well be due to being at an airport. I also pointed out that high temperature records in the Los Angeles area could be a product of poor siting. Such as this station on the roof of the Santa Ana fire station:
