A wildfire moves at speeds of up to 14 miles an hour 23 kilometers an hour , consuming everything—trees, brush, homes, even humans —in its path. There are three conditions that need to be present in order for a wildfire to burn, which firefighters refer to as the fire triangle: fuel, oxygen, and a heat source. Fuel is any flammable material surrounding a fire, including trees, grasses, brush, even homes.
The greater an area's fuel load, the more intense the fire. Air supplies the oxygen a fire needs to burn. Heat sources help spark the wildfire and bring fuel to temperatures hot enough to ignite. Lightning, burning campfires or cigarettes, hot winds, and even the sun can all provide sufficient heat to spark a wildfire.
Although four out of five wildfires are started by people, nature is usually more than happy to help fan the flames. Dry weather and drought convert green vegetation into bone-dry, flammable fuel; strong winds spread fire quickly over land; and warm temperatures encourage combustion. When these factors come together all that's needed is a spark—in the form of lightning, arson, a downed power line, or a burning campfire or cigarette—to ignite a blaze that could last for weeks and consume tens of thousands of acres.
People rushed to buy electric fans, but stocks were quickly exhausted. High-speed trains were forced to slow down because of fears the extreme heat was causing rails to expand, and sections of motorway were closed.
The French government has imposed emergency measures including cold rooms in public buildings and temporary water fountains. Parks are being left unlocked at night so people can cool off. T he torrid heat has scorched vineyards in southern France, causing up to 40 per cent of grapes to wither on the vines in the Languedoc region.
I n Italy, three people were reported to have died of heat-related causes. Milan saw sporadic power blackouts as the demand for air conditioning strained the electricity supply. Some 40 rescued migrants have been on the Sea-Watch 3 for six weeks while the vessel was locked in a stand-off with Italian authorities who refused to allow it to land.
