Severe weather can occur under a variety of situations, but three characteristics are generally needed: a temperature or moisture boundary, moisture, and (in the event of severe, precipitation-based events) instability in the atmosphere.

Although heat waves do not cause as much economic damage as other types of severe weather, they are extremely dangerous to humans and animals: according to the United States National Weather Service, the average total number of heat-related fatalities each year is higher than the combined total fatalities for floods, tornadoes, lightning ...
Projections of future climate change suggest further global warming, sea level rise, and an increase in the frequency and severity of some extreme weather events and weather-related disasters. Effects of global warming include loss of biodiversity , stresses to existing food-producing systems, increased spread of known infectious diseases such ...
An environmental disaster or ecological disaster is defined as a catastrophic event regarding the natural environment that is due to human activity. [2] This point distinguishes environmental disasters from other disturbances such as natural disasters and intentional acts of war such as nuclear bombings .
Flows can move imperceptibly for years, or accelerate rapidly and cause disasters. Slope deformations are slow, distributed movements that can affect entire mountain slopes or portions of it. Some landslides are complex in the sense that they feature different movement types in different portions of the moving body, or they evolve from one ...
The scientific community has been investigating the causes of climate change for decades. After thousands of studies, it came to a consensus , where it is "unequivocal that human influence has warmed the atmosphere, ocean and land since pre-industrial times."
