Climate change
Temperature is the main indicator used to describe and characterize the climate. Rising air temperatures can lead to more intense heat waves, which can cause illness and death, especially for vulnerable populations. Annual and seasonal temperature patterns also determine the species of animals and plants that can survive in certain places. Local significant changes in annual and / or seasonal temperatures can disrupt a wide range of natural processes in nature, especially if these changes occur faster, thus leaving many local plant and animal species unable to adapt.
Precipitation have wide-ranging effects on human well-being and ecosystems. Rainfall, snowfall, and the timing of snowmelt can all affect the amount of surface water and groundwater available for drinking, irrigation, and industry. They also affect river floods and can determine what species of animals and plants (including crops) can survive in a given place. Changes in rainfall in a region can disrupt natural processes, especially if these changes occur faster, thus thwarting the ability of the local plant and animal species to adapt.
