How does climate change deteriorate fire?



Severe fires in northern and southern California have been seen in recent years in the United States and other countries around the world. AFP scientists have talked about climate change and ways to deteriorate them.

Other factors have also increased the frequency and intensity of major fires, including the humiliating humiliation of forests and the doubtful management of forests. "The patient has already been sick," says Dr. David Bowman, Professor of Biology and Environmental Specialist at Tasmanian University.

"But climate change is an accelerator."

Good weather for the weather

Any firefighter offers you a recipe for "firefighting": hot, dry and windy.

Therefore, it is not surprising that many tropical and normal zones disappeared because of forest fires are predicted to be seen in climatic models with high temperatures and droughts.

Christopher Williams of Clark University, Massachusetts, states, "Climate change, including dry and hot air, can trigger emerging ecosystems by increasing the rate of evaporation and the spread of drought."

Over the past 20 years, several droughts have emerged in California and Southern Europe once in a century.

Additional fuel

Dry weather means more trees, shrubs and herbs – fuel for fire.

"Most of these dry years make dried biomass," says Michel Vennaneer (IRSTEA), a French researcher for environmental and agricultural science and technology researchers.

"It was very flammable."

Landscape change

Because of problems deteriorating, new species will grow instead of well-adapted to the poluacid conditions.

"The plants like moisture have disappeared, resistant to dry conditions, such as rosemary, wild lavender and thyme have been replaced by plants," says Wennyer.

"The changes will take place very quickly."

Acid plants

As a result of growing mercury and rain, water-ridden trees and shrubs spread deep roots to the soil and suck each drop of water to feed the leaves and needles.

This does not mean that there is no moisture that can help the fire to wipe the forest or to slow it down to garbage.

Long season

In the normal northern hemisphere, the season of fire was historic and short – in July and August, in many places.

"The sensitive period of the fire has been extended in June and October," said Irste, a scientist who wrote a reference to the Mediterranean basin.

In California, where only five years of drought arose, some experts say that there was no season throughout the year.

Lightning Thunderstorm

Professor of the University of Alberta, Mike Flannigan, says the West's director for Wildland Fire Science says, "The more thunderstorm you get, the more lightning you have."

"Particularly in the northern regions this will lead to an increase in fire."

He also said that 95 percent of the world's fires began with human beings.

Airport flow weakening

Normal North American and Eurasian weather patterns depend on powerful, high altitudinal airflows that receive contrast between polar and equatorial temperatures known as air flow.

However, global warming has diminished the Arctic climate by double the global average.

Flannigan: "We are referred to as the elevated weather, because we are a high-pressure system.

"Firefighters know that for decades they will be able to extinguish the fire."

Intensity of weakness

Climate change not only increases the probability of fire, but also increases their intensity.

In California, if the fire is very intense, and last summer in Greece, "it's not a direct action to stop it," says Flannigan.

"It looks like a fire burns."

Infection of the beetles

With the rise of temperature, the beetles moved north to the boreal forest of Canada, destroyed trees and killed them.

"The cucumber beetle temporarily increases forest fires by burning dead material like needles," said Williams.

Positive feedback

In fact, forests account for 45 per cent of the world's land, which is dried, and absorbs about a quarter of human greenhouse gases.

But if forests are dead and burned, some carbon is released into the atmosphere and influenced by climate change, and scientists call it a 'positive feedback'.
