Climate change the potential impact on

Efforts should be made to improve the standardising of instrumentation and calibrations of UV measurement.

Why is global warming a problem

Consumer interest in environmentally benign technologies may stimulate their growth. In the Northern Hemisphere, these vector-borne diseases could move northward and in the Southern Hemisphere southward. Chapter 6 discusses these potential impacts of sea-level rise in more detail. Projected impacts of such a thawing include a large a area of thaw settlement and slope landslide with destruction of highways, railways and housing built on permafrost Ye, Model predictions are based on a number of assumptions about factors ranging from future rates of warming and economic growth to the technological and social achievability of different levels of emissions cuts. Damage by tropical cyclones is a major impediment to economic development throughout the Caribbean region and can be expected to become an even larger factor if storm damage increases Granger, Overall, the effective UV-B varies both among species and among cultivars of a given species. Various experiments have demonstrated that UV-B radiation causes damage to fish larvae and juveniles, shrimp larvae, crab larvae, copepods, and plants essential to the marine food web US EPA, There is concern that UV-B radiation, suppression of the immune system might lead to an increase of the incidence and severity of infectious diseases. More research is needed to obtain base-line information on different disease systems. Extremely hot nights have doubled in frequency. Ecosystems are also highly vulnerable to climate change, which can aggravate existing stress factors such as pollution, land conversion and invasive non-native species. Smith, Joel B. Changnon, Stanley A.

Global warming has the potential to seriously disrupt our food supplydrive costs upward, and affect everything from coffee to cattle, from staple food crops to the garden in your backyard. Current changes are expected to continue and intensify in the future The impacts of future climate change and related sea-level rise will be experienced in many areas, from the natural environment to food security and from human health to infrastructure.

List of effects of climate change

The coast can also be considered a region, and will suffer severe impacts from sea level rise. Morris, R. This is a particularly significant factor in the Caribbean region Granger, and has recently contributed to huge losses in the southern US as well. East Coast. Takeuchi, U. While deaths of infants under the age of one were not examined, the categories which appeared most sensitive to weather are total deaths and elderly deaths greater than 65 years old. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner. Climate change impacts depended strongly on projected future social and economic development. Migration may be a preferred response to threatened loss of housing or employment. Oceans Main article: Effects of global warming on oceans The role of the oceans in global warming is complex. At present there are substantial scientific uncertainties about the nature and magnitude of climatic changes that might result from an effective doubling of CO2 concentrations in the atmosphere. Yale University Press. Vegetation and soils dry out earlier, setting the stage for longer and more damaging wildfire seasons.

One can reliably predict that certain developing societies will be more vulnerable to climate changes than highly industrialised countries because they are already at the limits of their capacity to cope with climatic events.

Migration may occur following a decline in living standards or a total loss of livelihood following land degradation itself possibly due to an earlier migration toward marginal land unable to support over-cultivation or a major 'natural' disaster like flooding or drought. Gery, M.

Warming in the Arctic and sub-Arctic could mean a shorter trapping season and reduced quality of furs, a major source of income for many Yukon Territory residents Klassen, Air Pollut. Some infectious diseases are well known to show apparent seasonal changes and would seem to be very sensitive to global warming.

Climate change the potential impact on

The area in which extremely hot summers are observed, has increased fold. Rosenberg, William E. In , the global estimate for the number of people undernourished was million. The same researchers reported that was the fifth warmest year in the years for which they have compiled global temperature records and that six of the ten warmest years on record were in the s Kerr, A consensus exists among the world's leading scientists that a continuation of the current rate of increase in concentrations of greenhouse gases GHG in the atmosphere will cause a significant increase in global average annual temperatures. Environ Pollut. Sometimes, frequent flooding has threatened the health of people in developing countries, directly or indirectly. Environmental Research, 17, pp. Owing to these abilities of adaptation, human beings can live throughout the world.

Without further adaptation, extremely hot episodes are expected to have the greatest impact on mortality in the hotter north, while in cooler southern Australia there is likely to be an offsetting reduction in the number of cold-season deaths. Adaptation to drought may include agropastoral management techniques providing for a more efficient use of reduced rainfall.

Climate change causes

Various experiments have demonstrated that UV-B radiation causes damage to fish larvae and juveniles, shrimp larvae, crab larvae, copepods, and plants essential to the marine food web US EPA, While that may bring some benefits, it could mean increased risk of drought, and extreme events such as the heatwave could be the norm by the end of this century. Evidence of warming is also apparent in living biological systems such as changes in distribution of flora and fauna towards the poles. OECD, Center of Development , 'La migration internationale dans ses relations avec les politiques d'adjustement industriel et agricole'. Climate change can have impacts on infrastructure such as electricity and transport networks. Any reduction of this marine productivity will undoubtedly affect global food supply Damkaer, Degradation of water quality or sanitation facilities could put more pressure on public health facilities. Climate warming causes land and ocean life to migrate away from areas that have become too warm, and towards areas that previously were too cool. Last, JA. Okita, T. Some impacts will be beneficial—e. Several areas, eg energy, transport, industry and human health, each of which is a central concern of human settlement, will be addressed separately in some detail in subsequent sections. Chapter 6 discusses these potential impacts of sea-level rise in more detail. The seasonal trends of major causes of death have changed. Takeuchi, U.
