Fire serves many important functions within fire-adapted ecosystems. Fire plays an important role in nutrient cycling, diversity maintenance and habitat structure. The suppression of fire can lead to unforeseen changes in ecosystems that often adversely affect the plants, animals and humans that depend upon that habitat.
Climate change promotes the type of weather that makes wildfires more likely. In some areas, an increase of wildfires has been attributed directly to climate change. [11]: 247 Evidence from Earth's past also shows more fire in warmer periods. [74] Climate change increases evapotranspiration. This can cause vegetation and soils to dry out.
The geographic poles are defined by the points on the surface of Earth that are intersected by the axis of rotation. The pole shift hypothesis describes a change in location of these poles with respect to the underlying surface – a phenomenon distinct from the changes in axial orientation with respect to the plane of the ecliptic that are caused by precession and nutation, and is an ...
Human-caused fires are also responsible for 97% of wildfires that threaten homes. People often start wildfires through dangerous actions, including open burning, campfires, firearms and equipment ...
It's not the reach of a fire that matters most; it's the speed. Understanding this can help society better prepare.
The heat produced by the wildfire changes the temperature of the atmosphere and creates strong updrafts, which can change the direction of surface winds. The water vapor released by the fire changes the moisture balance of the atmosphere. The water vapor can be carried away, where the latent heat stored in the vapor is released through ...
The fires have caused widespread devastation in Lahaina, a beach resort city of about 13,000 people on northwestern Maui that was once a whaling center and the Hawaiian Kingdom's capital and now ...
More importantly, fires have long-term effects on the post-burn environment. Fires in seldom-burned rainforests can cause disasters. For example, El Niño-induced surface fires in central Brazilian Amazonia have seriously affected the habitats of birds and primates. [22] Fires also expose animals to dangers such as humans or predators.
