Wildfires are currently raging in Turkey, Greece and Bulgaria amid a 44°C heatwave, ongoing droughts and strong winds. A map from Nasa shows how flames have spread across the region in the last week despite efforts to contain them. What has become clear is that climate change is accelerating the disaster in a region already on the brink.

Wildfires that have engulfed Turkey for weeks spread rapidly overnight, threatening Bursa and forcing 3,500 to flee. Greece and Bulgaria are also contending with fires.

Firefighters battled on Monday to put out wildfires in three separate provinces of Turkey, in Greece and near a tourist resort in Albania, stoked by strong winds after days of searing heat across the Mediterranean region.
