NASA is a world leader in climate studies and Earth science. While its role is not to set climate policy or prescribe particular responses or solutions to climate change, its purview does include providing the robust scientific data needed to understand climate change.

The effects of climate change span the physical environment , ecosystems and human societies. It also includes the economic and social changes which stem from living in a warmer world. Human-caused climate change is one of the threats to sustainability.

Global Warming 101

The effects of climate change on humans are far reaching and include effects on health, environment, displacement and migration , security, society, human settlement , energy, and transport. Climate change has brought about possibly irreversible alterations to Earth's geological, biological, and ecological systems. A growing body of research explores the many impacts of climate change on human health, food supply, economic growth , migration , security, societal change, and public goods , such as drinking water. The consequences of these changes can help or hurt local human populations. For example, climatic changes in Siberia are expected to improve food production and local economic activity in the short to medium term. However, Bangladesh has experienced an increase in climate-sensitive diseases; such as malaria, dengue, childhood diarrhea, and pneumonia, among vulnerable communities.

What causes the Earth's climate to change?

During the course of global warming, the energy balance and thus the temperature of the earth change, due to the increased concentration of greenhouse gases, which has a significant impact on humans and the environment. It is not scientifically possible to assign individual weather events to the current climate change, however, it can be statistically proven that global warming will increase the probability of extreme weather events. The indirect consequences of climate change, which directly affect us humans and our environment, include:. As the global climate is a highly interconnected system that is influenced by many different factors, the consequences usually result in positive or negative feedback effects. This refers to developments that are self-enhancing due to the occurrence of certain conditions. A common example is the ice-albedo feedback, which refers to the melting of the polar caps.

And scientists say that unless we curb global-warming emissions, average U. Normally, this radiation would escape into space—but these pollutants, which can last for years to centuries in the atmosphere, trap the heat and cause the planet to get hotter.

Research has also evaluated actions that could be taken—and in some cases are already being taken—to limit the magnitude of future climate change and adapt to its impacts. In the United States, a series of reports by the U. Internationally, scientific information about climate change is periodically assessed by the Intergovernmental Panel on Climate Change IPCC , most recently in

The climate of an area determines its seasons and when they come and go. This, in turn, affects the type of plants that grow and which animals survive. The species and places we love depend on intricate ecosystems, and even small changes to the climate can disrupt the delicate balance of nature.

Effects of climate change on humans

The potential future effects of global climate change include more frequent wildfires, longer periods of drought in some regions and an increase in the number, duration and intensity of tropical storms. Global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner.

Global climate change has typically occurred very slowly over thousands or millions of years. However, research shows that the current climate is changing more rapidly than shown in geological records. During the last ice age, the British Isles had many glaciers like the example above, located in present-day Iceland. The energy output of the Sun is not constant, it varies over time and this has an impact on our climate. The period between these changes happen over 10s of s of years precession and axial tilt to more than s of s of years eccentricity.

Global Warming - Impacts and Future Perspective. Global warming and climate change refer to an increase in average global temperatures. Natural events and human activities are believed to be main contributors to such increases in average global temperatures. The climate change, caused by rising emissions of carbon dioxide from vehicles, factories and power stations, will not only effects the atmosphere and the sea but also will alter the geology of the Earth. Emissions of carbon dioxide due to our use of fossil energy will change the climate and the temperature is estimated to increase by 2 to 6 o Celsius within year , which is a tremendous increase from our current average temperature of 1. This may cause huge changes to our civilization, both positive and negative, but the total impact on our society is currently very uncertain. Forecasts indicate that major storms could devastate New York City in next decade whereas Gulf countries will get affected badly well before.

Climate change is the global phenomenon of climate transformation characterized by the changes in the usual climate of the planet regarding temperature, precipitation, and wind that are especially caused by human activities.

Climate Change: Meaning, Definition, Causes, Examples And Consequences

Climate change, also called global warming, refers to the rise in average surface temperatures on Earth. An overwhelming scientific consensus maintains that climate change is due primarily to the human use of fossil fuels, which releases carbon dioxide and other greenhouse gases into the air. The gases trap heat within the atmosphere, which can have a range of effects on ecosystems, including rising sea levels, severe weather events, and droughts that render landscapes more susceptible to wildfires. There is broad-based agreement within the scientific community that climate change is real.

Global warming , the phenomenon of increasing average air temperatures near the surface of Earth over the past one to two centuries. Increases in greenhouse gases —i. Continued global warming is expected to impact everything from energy use to water availability to crop productivity throughout the world. Poor countries and communities with limited abilities to adapt to these changes are expected to suffer disproportionately.

Мы погибли. - Теряем фильтры Протокола! - раздался чей-то голос.  - Открылся третий уровень защиты! - Люди в комнате засуетились. На экране агент с короткой стрижкой безнадежно развел руками. - Сэр, ключа здесь .

The burning of these fuels produces gases like carbon dioxide, methane and nitrous oxides which lead to global warming. Deforestation is also leading to warmer temperatures. The hazard of global warming is continuously causing major damage to the Earth's environment.
