Summer in autumn: heat records and the first orange alert in history in October

Flip-flops in October and weather forecasts that still keep weather away from shelter are further proof that something is not right; one more certainty that the climate crisis keep it up. Summer ended in September, but its temperatures persist. So much so that this Wednesday, the State Meteorological Agency (Aemet) has issued the first orange alert in the month of October since there have been records, which indicates that thermometers reach unusual figures for this time of year.

The month of September, despite its beginning marked by torrential rains and the DANA that shook the center of the peninsula, has closed with temperatures more typical of the month of August than the beginning of autumn. The country’s thermometer, in the last week of the month, has hovered around 35ºC in a good part of the map, even in areas that, at this time of year, are already marked by rain and cold such as Galicia, which registered 36ºC in Ourense .

The Aemet forecasts, at the end of September, spoke of a month of October marked by “unusual” temperatures. The thermometers have not taken long to confirm that the country has not managed to escape summer. So much so that on October 1, 33 temperature records were broken for the month. Still, according to the Agency’s meteorologists, there are still weeks of heat left before records are broken again.

Of the 33 stations in the country that recorded unprecedented temperatures that day, only four – Jaen, Navacerrada, Soria and Daroca – broke records that were recorded in the last century. That is, 39 of the surpassed brands were already concentrated in the 21st century. Additionally, 12 of those old record highs that were broken occurred in the last decade. The way in which extreme temperature records occur and are concentrated in recent decades is an example of how the planet’s global thermometer is rising little by little as a result of the climate crisis.

On October 2, according to Aemet records, temperature records were broken again in seven stations. The surprising thing is that, except for the case of Bilbao, the rest of the brands surpassed records that had been reached the previous day.

“The climate crisis manifests itself in an increase in temperatures in general and in a lengthening of the summer that we are experiencing in Spain and that is why September is being affected, with milder temperatures. In general we can say that climate change is tempering the seasons and in the case of summer, extreme heat,” says Mar Gómez, doctor in Physics and meteorologist of the portal the time is.

Towards the climate abyss

What happens in Spain is nothing more than a reflection of what happens on the planet. The data reveal that September, on a global scale, registered a record for average temperature, with more than 0.5ºC compared to the previous record. As John Kennedy, a researcher at the United Kingdom Meteorological Service, has explained, this is the most abrupt rupture since there are records, since the previous September with the highest rise in temperatures occurred in the 40s of the 20th century with an increase in only 0.2ºC.

The constant breaking of records and the escalation of global temperatures leaves the planet close to the abyss. Emissions of CO2 and gases that accelerate global warming rose by 1% in the last year, according to the latest data published by the UN, and the objectives that humanity set for itself less than a decade ago, in 2015, are beginning to be reached. seem out of date.

Gómez explains that “we are currently 1.1ºC above pre-industrial temperature values.” The political leaders, supported by scientific data, agreed to work so that the planetary thermometer did not exceed the threshold of 1.5ºC and, according to the doctor in physics, “the projections are not good.” “The average annual temperature has increased between 0.08ºC and 0.09ºC per decade since 1980,” she adds.

The rate of warming has doubled and there are already scientists who point out that, with the increase in greenhouse emissions, the rate at which temperatures rise is going to accelerate. Researchers at Columbia University have already shown that the El Niño phenomenon that is currently active (an event that occurs approximately every eight years and that entails, among other things, a rise in temperatures in various parts of the planet) suggests that the The rate of global warming could increase by 50% compared to the previous decade. In this way, the commitment of the Paris Agreement to stop the climate emergency could remain a dead letter and the planet could reach the 1.5ºC mark by the end of the decade.
