A significant rise has been witnessed in the length of wildfire seasons across the world owing to climate change, finds a new research. Researchers have stated that in the last three decades, burnable areas on earth have increased.

The research titled, Climate induced variations in global wildfire danger from 1979 to 2013, was compiled by researchers from USDA-Forest Service, South Dakota State University, the Desert Research Institute and the University of Tasmania, Australia.

With the help of wind tunnels and massive burn chambers, the researchers have conducted the research. One of the study researchers Matt Jolly, Fire Sciences Lab ecologist at the Rocky Mountain Research Station in Missoula, said that they wanted to come up with a way by which they could find out how cumulative weather changes influence global fire.

Wildfire activity happens due to three main factors, Fuels, sources of ignition and weather. The researchers said that climate change has made development of conditions quite perfect for wildfire by factors like higher temperatures, lower humidity, reduced rainfall and higher surface wind speeds.

Jolly said, "So we separated weather from the other driving factors in order to isolate the impacts of climate change on wildland fire potential". It was found that there has been a long-term gradual increase in wildfire seasons that normally do not witness them, like southeastern US.

Except Australia and most vegetation types have witnessed significant increases in the fire weather season length.
