Models that also account for the greenhouse gases emitted by humans are able to explain this warming. Click the image to view a larger version. When incoming energy from the sun is absorbed by the Earth system, Earth warms. When absorbed energy is released back into space, Earth cools.
A article in the American Psychologist identified three classes of psychological impacts from global climate change: The topic of climate change is very complex and difficult for people to understand, which effects how they act upon it.
It is shown by Ranney and Clark  that by informing people to make them understand the topic of climate science clearly, it promotes the change in behaviour towards mitigation of climate change. Extreme weather events[ edit ] Further information: Extreme weather This trend towards more variability and fluctuation is perhaps more important, in terms of its impact on human health, than that of a gradual and long-term trend towards higher average temperature.
Effects of global warming on infectious diseases Climate change may lead to dramatic increases in prevalence of a variety of infectious diseases. Malaria kills approximatelychildren under age 5 annually, poses an imminent threat through temperature increase.
Patz and Olson argue that these changes in landscape can alter local weather more than long term climate change. It is highly unlikely that climate exerts an isolated effect.
Environment[ edit ] Climate change may dramatically impact habitat lossfor example, arid conditions may cause the deforestation of rainforestsas has occurred in the past. A study by NOAA from concluded that heat stress will reduce labor capacity considerably under current emissions scenarios.
Water crisis The freshwater resources that humans rely on are highly sensitive to variations in weather and climate. Inthe IPCC reported with high confidence that climate change has a net negative impact on water resources and freshwater ecosystems in all regions.
Warmer water temperatures affect water quality and accelerate water pollution. This reduces the amount of freshwater available for drinking and farming.
This situation is particularly acute for irrigation in South America,  for irrigation and drinking supplies in Central Asia, and for hydropower in Norway, the Alps, and the Pacific Northwest of North America.
Increased extreme weather means more water falls on hardened ground unable to absorb it, leading to flash floods instead of a replenishment of soil moisture or groundwater levels. At the same time, human demand for water will grow for the purposes of cooling and hydration.
Displacement and migration[ edit ] See also: Environmental migrant A refugee camp Climate change causes displacement of people in several ways, the most obvious—and dramatic—being through the increased number and severity of weather-related disasters which destroy homes and habitats causing people to seek shelter or livelihoods elsewhere.
Effects of climate change such as desertification and rising sea levels gradually erode livelihood and force communities to abandon traditional homelands for more accommodating environments.
Deteriorating environments triggered by climate change can also lead to increased conflict over resources which in turn can displace people.
This figure includes those displaced by storms, floods, and heat and cold waves. Still others were displaced drought and sea-level rise. Most of those compelled to leave their homes eventually returned when conditions improved, but an undetermined number became migrants, usually within their country, but also across national borders.
It is highly exposed to climate impacts, and is home to highly vulnerable population groups, who are disproportionately poor and marginalized.Factors that Influence Climate, are prevailing global wind patterns and altitude.
Weather Information World Weather Home Factors that Climate Change - Climate change is a long-term change in the statistical distribution of weather patterns over periods of time that range from decades to . Just look at any globe or a world map showing land cover, and you will see another important factor which has a influence on climate: the surface of the Earth.
The amount of sunlight that is absorbed or reflected by the surface determines how . The Politics of Climate.
Polarized views about climate issues stretch from the causes and cures for climate change to trust in climate scientists and their research. The Influence Of Climate Change On Hydrological Extremes: Floods & Droughts by Renata Romanowicz Climate change impact on hydrological extremes was studied by the project under the same name, acronym CHIHE, over the years Key vulnerabilities.
Most of the key vulnerabilities to climate change are related to climate phenomena that exceed thresholds for adaptation; such as extreme weather events or abrupt climate change, as well as limited access to resources (financial, technical, human, institutional) to cope.
Climate change is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time (i.e., decades to millions of years). Climate change may refer to a change in average weather conditions, or in the time variation of weather .
