A period of weather characterized by excessively low temperatures, which may or may not also be accompanied by changes in humidity. Very cold weather is often only referred to as a cold wave if the temperature, or the rate at which the temperature decreases within a given time period, is abnormal relative to the typical climate for a given ...
Extreme weather events affect public health, and food and water security. [239] [240] [241] Temperature extremes lead to increased illness and death. [239] [240] Climate change increases the intensity and frequency of extreme weather events. [240] [241] It can affect transmission of infectious diseases, such as dengue fever and malaria.

The extreme winter weather and power outage crisis left millions without a source of heat that then led to scores of frozen, ruptured pipes and serious damage in Texas alone.
Climate variability is the term to describe variations in the mean state and other characteristics of climate (such as chances or possibility of extreme weather, etc.) "on all spatial and temporal scales beyond that of individual weather events." Some of the variability does not appear to be caused by known systems and occurs at seemingly ...
