KRYO PIGADI, Greece (AP) — Skimming over miles of hills blackened by wildfires west of Athens, Fire Lt. Col. Ioannis Kolovos readies his elite fire crew crouched inside a helicopter.

The 10-member group from the 1st Wildfire Special Operation Unit bristles with tools needed to hold back fires: chainsaws, specialized rakes, weather gauges, computer tablets and earth-scorching drip torches to burn wildfire barriers into the hillside.

Greece’s fire season officially starts May 1, but dozens of fires have already been put out over the past month after temperatures began hitting 30 degrees Celsius (86 degrees Fahrenheit) in late March — considerably higher than previous spikes recorded over the past decade.

“It’s actually already summer for us,” Kolovos told The Associated Press during a recent training exercise. “The truth is that the fire season has started prematurely and has been extended over the last five years.”
