Cold-Waves
Cold-waves are more prevalent in northern regions, and are associated with increased risks of conditions such as hypothermia and frostbite. These conditions are especially prevalent following accidental cold exposure among populations such as the homeless, elderly, or outdoor workers. However, mortality resulting from cold-related incidents has decreased since the 1950s. This has been attributed to both a general decrease in the amount of extreme cold weather events, as well as improvements in heating systems and cold exposure prevention or awareness.

Droughts[edit]
Further information: Effects of climate change § Droughts

Climate change affects multiple factors associated with droughts, such as how much rain falls and how fast the rain evaporates again. Warming over land increases the severity and frequency of droughts around much of the world. Many of the consequences of droughts have effects on human health. This can be through destruction of food supply (loss of crop yields), malnutrition and with this, dozens of associated diseases and health problems. [new] Drought has been linked to decreased dietary diversity and food consumption, leading to an increase in micronutrient deficiencies. Drought and disease have been shown to be closely linked, with malnutrition resulting from drought in Bangladesh being linked to an increased prevalence and mortality from diarrheal disease (Aziz 1990). Drought has led to population displacement and subsequent migration, especially among rural communities, which has led to increases in communicable disease transmission and lack of access to nutritious food and water.
