climate change

One of the main strategies for mitigating CO₂ emissions is the electrification of vehicles. Although taking vehicles that are still in good condition off the road has an environmental impact, a study published in the journal Science has shown that replacing them with battery electric vehicles brings long-term benefits, even when taking into account the emissions resulting from their manufacture. To address this issue, the authors estimated the life-cycle CO₂ emissions associated with keeping a combustion-engine vehicle in use, compared with scrapping it early and replacing it with an electric vehicle. The results show that the carbon footprint of manufacturing the new vehicle is reduced, as electric cars emit only a third of the greenhouse gases produced by combustion-engine vehicles.

Human-induced climate change has made the ‘extreme’ weather conditions that fuelled the recent wildfires at least twice as likely in France and 20 times as likely in Spain, according to a new analysis by World Weather Attribution (WWA). The team analysed historical weather observations and used the Daily Severity Index (DSR), which incorporates heat, drought and wind conditions and reflects the difficulty of extinguishing a fire. The researchers examined the seven-day period with the highest DSR in south-western France and central Spain, where the fires occurred, and compared it with simulations of a pre-industrial climate. According to the study, under current climate conditions, events of this intensity are projected to occur once every 20 years in south-western France and once every six years in central Spain.

In some areas of Spain and France, the intensity of weather conditions that favour wildfires — heat, drought and wind — increased by up to 50 per cent between 2016 and 2025, compared with the period between 1981 and 2010. This is one of the conclusions of a study carried out by a team including Spanish researchers, which analysed national records of forest fires in southern Europe – Spain, Portugal, France, Italy and Greece – alongside meteorological and climatic data from 1981 to 2025. The data, published in Scientific Reports, show that the number of days with conditions conducive to fires also increased in some areas of these countries. However, the annual number of fires over the last decade was 40 per cent lower than in the 1981–2010 period in all countries – a decline which, according to the authors, is consistent with a reduction in fires caused by humans, driven by stricter regulations.

The fire in Ávila, which merged with the one in the south-western mountains of Madrid last Saturday and spread to the province of Toledo, remains unstabilised, although it is under control in some areas. Wind gusts of up to 30 km/h will complicate fire-fighting efforts on Monday, according to the Madrid 112 Safety and Emergency Agency. The fire in Ávila is now the largest in Spain’s recent history. Meanwhile, the fire that broke out on Saturday in La Vall d’Uixó (Castellón), which has spread into the Sierra de Espadán Natural Park, has not yet been stabilised either. In total, around 100,000 people have been evacuated or are under lockdown across all the fire fronts.

Early this morning, the Minister of Interior, Fernando Grande-Marlaska, declared a state of emergency of national interest in the Community of Madrid and the province of Ávila due to the forest fires in Villa del Prado, San Martín de Valdeiglesias and Burgohondo. According to Carlos Novillo, the Regional Minister for the Environment, Agriculture and the Interior of the Community of Madrid, the fires were beyond the capacity of the fire services to extinguish and posed a serious threat to the population. The Madrid 112 Security and Emergency Agency has reported that, although the night-time firefighting efforts have been effective, the fires have still not been contained or brought under control. More than 10,000 people remain evacuated.

Data from the Copernicus European Forest Fire Information System (EFFIS) show that, as of 22 July, 119,458 hectares have been burnt in Spain. The average number of hectares burnt from 2006 to 2025 up to this date stands at 35,736 hectares. The fire in the Sierra Norte de Guadalajara, which has scorched more than 30,000 hectares and is still active, together with numerous fire fronts in other provinces and the fire in Los Gallardos (Almería), in which 13 people died, have caused the total area burnt to soar.

Various studies show that extreme heat is already influencing the decisions of international tourists, who are cutting short their summer holidays in the Mediterranean and opting for coolcations in search of destinations with milder climates. Climate adaptation is becoming a priority and, in the face of increasingly intense heatwaves, may boost the appeal of spring and early autumn.

International entertainment events have a very high carbon footprint. The majority of this stems from emissions caused by spectators’ travel, which account for 82 per cent of the emissions from the 2026 FIFA World Cup and 97 per cent of those from Coldplay’s 2024 European tour, according to a study published in Communications Sustainability which analyses the environmental impact of both mega-events. The researchers propose that organisers should bear part of the carbon costs by rewarding fans with discounts for choosing more environmentally friendly modes of transport to attend the events.

Concentrations of desert dust rose steadily across much of Europe between 2012 and 2021, according to a study published today in the journal Nature. This was despite the fact that particulate matter pollution from emissions had fallen as a result of regulations. The trend could be linked to changes in atmospheric circulation and desertification in North Africa. Some of the largest increases were recorded in southern Europe and the Mediterranean region, where levels are more than double those in the north of the continent. The authors warn that dust pollution could have an increasing impact on air quality and public health.

The wildfire in Los Gallardos (Almería), which broke out on Thursday evening, has so far claimed 13 lives. Initial investigations suggest that a fallen power line may have been the cause of the fire. The blaze has burnt more than 3,000 hectares and has left 1,400 people displaced.
