Particulate Matter -- Particulate matter comes from cars, trucks, construction equipment, coal-fired power plants, vegetation, open air burning, and livestock. Short-term exposure to particulate matter can lead to acute impairment of lung function.
Ozone -- Ozone is formed in the air by a chemical reaction between volatile organic compounds (VOCs) and nitrogen dioxide when the weather is warm and during the sunny hours of the day. exposure to ozone in the air can make existing health conditions like asthma, chronic obstructive pulmonary disease, and allergies worse, leading to a further decrease in lung function, cause wheezing and asthma attacks and even lead to death.
Pollen and Mold -- Pollen is derived from trees and grass. Molds are forms of fungi that are found naturally in the environment. Climate change is lengthening the growing season for allergenic plants, increasing the amount of pollen produced and the ability for pollen to cause allergic responses. This change may affect people who already suffer from seasonal allergies and may potentially increase the number of people who suffer from allergies.
creating conditions that promote the spread of vector-borne diseases
increasing the occurrence of food-borne illnesses, malnourishment and food insecurity
causing conditions that can result in the contamination of drinking water.
Direct effect -- changes in temperature, humidity, rainfall can alter where vectors (vectors are also known as carriers, i.e. mosquito and ticks) multiply and the life-cycles of the germ they transmit.
Indirect effect -- climate change can alter biological factors such as the timing and type of plants that grow, the animals that migrate to and from an area, and human behavior.
worsening coastal flooding
influencing shoreline erosion
submerging tidal wetlands
In the past, water resource managers and water utilities have relied on predictable variations in climate conditions and water availability. Changes in climate conditions may mean that these previous assumptions are no longer valid. The table below shows the expected impacts of climate change to drinking water:
