Catalonia has been burning for days. The asphalt is boiling in the cities, apartments are suffocating in the densest neighborhoods, and in many towns, shade is a rare luxury. The heat wave is relentless, with record temperatures approaching day after day. But not everyone experiences it the same way. For some, it's a nuisance; for others, a threat.

"We ask that there are no trips to Collserola if they are not essential". This has been the appeal that the deputy mayor of Prevention and Security of the City Council of Barcelona, Albert Batlle, has launched on Friday, in the face of the heat wave that affects Catalonia and that is predicted to continue during the next days. Batlle has asked the people of Barcelona to try to "limit" their presence in the Collserola mountain range in the face of the high risk of fires due to the high temperatures. "The scenario is worrying", said the alderman, who has called the situation "critical". On Thursday the Barcelona City Council activated the municipal action plan for fire risk, which involves intensifying reinforcements to prevent new fires.
