how does climate change affect food system stability?
42649
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 will affect Danish natural habitats and the species composition of plants and animals. Rising water levels and more precipitation could cause flooding and other impacts on coastal habitats, for example.

Seasonal changes in precipitation and temperature affect soil moisture, evaporation rates, river flows, lake levels, and snow cover. Leaves fall and plants wither as cold and dry seasons approach. These changes in vegetation affect the type and amount of food available for humans and other organisms.

How does climate change affect oceans and marine life? ... Sudden rises in temperature and acidification can lead to the loss of marine habitats and species. Shifting ocean currents and warming waters are changing the distribution of fish stocks and altering the structure of ecosystems.

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.

The effects of climate change could be devastating to vulnerable coastal and marine areas as well as to the function and structure of their ecosystems. Increasing sea level (1,7 mm/year) changes the shape of coastlines, contributes to coastal erosion and leads to flooding and more underground salt-water intrusion.

Climate change aggravates the effects of population growth, poverty, and rapid urbanisation. Without serious adaptation, climate change is likely to push millions further into poverty and limit the opportunities for sustainable development and for people to escape from poverty.

Climate change affects the social and environmental determinants of health – clean air, safe drinking water, sufficient food and secure shelter. Between 2030 and 2050, climate change is expected to cause approximately 250 000 additional deaths per year, from malnutrition, malaria, diarrhoea and heat stress.

Global analyses show that the amount of water vapor in the atmosphere has in fact increased due to human-caused warming. This extra moisture is available to storm systems, resulting in heavier rainfalls. Climate change also alters characteristics of the atmosphere that affect weather patterns and storms.

There are a number of ways climate change may contribute to drought. Warmer temperatures can enhance evaporation from soil, making periods with low precipitation drier they would be in cooler conditions.

Our analysis showed that climate change has already affected crop yields around the world. ... For example, we estimated that climate change was reducing global rice yields by 0.3% and wheat yields by 0.9% on average each year. In contrast, some more drought-tolerant crops have benefited from climate change.

Climate change will also have many non-thermal impacts on fish populations. For example, changes in the strength, direction and location of ocean currents can affect the probability that fish eggs and larvae survive and grow. Moreover, as temperatures rise, the ability of the ocean to retain oxygen will decrease.

The authors point out that global climate change could affect the food supply to the deep sea in many ways. Some relevant ocean processes that may be affected by climate change include wind-driven upwelling, the depth of mixing of the surface waters, and the delivery of nutrients to surface waters via dust storms.

Climate change affects human health and wellbeing through more extreme weather events and wildfires, decreased air quality, and diseases transmitted by insects, food, and water.

Higher temperatures, an increased frequency of storms, sea level rise, and other effects of climate change are likely to affect fish physiology and ecology as well as the operation of aquaculture. Some fish species, such as catfish, may grow more rapidly with higher temperatures but be more vulnerable to disease.

Biologists have analyzed to what extent plant diversity influences the stability of climate–vegetation interaction. ... Plants need sunlight and rain, the vegetation in turn changes heat fluxes between soil and atmosphere as well as evaporation and water storage in the soil.

Climate change is modifying fish distribution and the productivity of marine and freshwater species. This has impacts on the sustainability of fisheries and aquaculture, on the livelihoods of the communities that depend on fisheries, and on the ability of the oceans to capture and store carbon (biological pump).
