Climate change can disrupt food availability, reduce access to food, and affect food quality. For example, projected increases in temperatures, changes in precipitation patterns, changes in extreme weather events, and reductions in water availability may all result in reduced agricultural productivity.

Climate change is making heavy intense downpours, droughts and rising water temperatures more common. This can alter the quality of our drinking and recreational water. Bacteria and viruses thrive in these new conditions and when they come into contact with humans, can cause numerous illnesses.

Higher mean temperatures as associated with climate change can have a severe impact on plants and animals by disrupting their mutually beneficial relationship: The pasque flower (Pulsatilla vulgaris), for example, is very sensitive to rising temperatures by flowering earlier each year, whereas one of its major ...

The effect of climate change on vegetation is expected due to changes in the temperature, rainfall, and climate pattern as a result of which nutrient cycles, microbial activities, as well as physiological activities of plants will vary. Changes in precipitation may change moisture regimes.

Climate change is affecting agricultural production in the Northeast. Heavy precipitation events can damage crops and wetter springs may delay planting, resulting in later harvest and reduced yields. Longer, drier summers may reduce water availability and increase plant heat stress, also reducing yields.

Climate change could improve soil quality by enhancing carbon sequestration through carbon farming, which involves growing things year-to-year without disturbing the soil, cover crops (which help spur microbial activity in the soil), and a grazing technique popularized by biologist Allan Savory called holistic ...

Climate change increases water and air pollution which can cause and aggravate chronic respiratory disease, such as asthma. Increased temperatures due to climate change lead to increased ground-level ozone, which cause airway inflammation and damages lung tissue.

Climate change is likely to have a mixture of positive and negative impacts on different parts of the food system, depending on the interplay between gradual temperature increase, extreme weather events, the CO2 fertilisation effect, changes in water availability, economic effects (e.g. trade), demographics and ...

According to the National Climate Assessment, climate change will affect human health by increasing ground-level ozone and/or particulate matter air pollution in some locations. ... The increase in air pollutants makes the effects of increased allergens associated with climate change even worse.

climate change affects biodiversity. Although throughout Earth's history the climate has always changed with ecosystems and species coming and going, rapid climate change affects ecosystems and species to adapt and so biodiversity loss increases.

Climate impacts on soil. Climate change can have a very big impact on soils and the functions that soil performs. In agriculture, climate change will affect crop production as changes in soil, air temperature and rainfall affect the ability of crops to reach maturity and their potential harvest.

Climate change may actually benefit some plants by lengthening growing seasons and increasing carbon dioxide. Yet other effects of a warmer world, such as more pests, droughts, and flooding, will be less benign. Under the HadGEM2 model, corn farmers will see crops decline by nearly 16 percent. ...

As the climate warms, it changes the nature of global rainfall, evaporation, snow, stream flow and other factors that affect water supply and quality. Specific impacts include: Warmer water temperatures affect water quality and accelerate water pollution.

The biggest changes in the land carbon cycle are likely to come because of climate change. Carbon dioxide increases temperatures, extending the growing season and increasing humidity. ... With less water, tropical trees slow their growth and take up less carbon, or die and release their stored carbon to the atmosphere.

Climate change is modifying fish distribution and the productivity of marine and freshwater species. ... The effect of sea level rise means that coastal fishing communities are significantly impacted by climate change, while changing rainfall patterns and water use impact on inland freshwater fisheries and aquaculture.

Climate change is likely to alter patterns of wind and water circulation in the ocean environment. Such changes may influence the vertical movement of ocean waters (i.e., upwelling and downwelling), increasing or decreasing the availability of essential nutrients and oxygen to marine organisms.
