In chaparral communities in Southern California, for example, some plants have leaves coated in flammable oils that encourage an intense fire. [20] This heat causes their fire-activated seeds to germinate (an example of dormancy) and the young plants can then capitalize on the lack of competition in a burnt landscape. Other plants have smoke ...
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.
Other traits such as serotiny and fire-stimulating flowering also have evolved for millions of years. [6] Some species are capable of using flammability to establish their habitats. For example, trees evolved with fire-embracing traits can "sacrifice" themselves during fires. But they also cause fires to spread and kill their less flammable ...
Debris flows have volumetric sediment concentrations exceeding about 40 to 50%, and the remainder of a flow's volume consists of water. By definition, “debris” includes sediment grains with diverse shapes and sizes, commonly ranging from microscopic clay particles to great boulders.
A vast majority of wildfires are started by people. Human-caused wildfires account for 88% of all wildfires in the United States on average over the last 10 years, according to the National ...
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 ...

Although temperate and tropical forests in total cover twice as much land as boreal forest, boreal forest contains 20% more carbon than the other two combined. [1] Boreal forests are susceptible to global warming because the ice/snow–albedo feedback is significantly influenced by surface temperature, so fire induced changes in surface albedo and infrared emissivity are more significant than ...
