File Name: causes and effects of global warming and climate change .zip
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.
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.
What is climate change? Is it the same as global warming? What are its main causes and consequences? Is it a lie? Find everything about climate change bel ow! 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.
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.
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.
Climate change deniers have argued that there has been a “pause” or a “slowdown” in rising global temperatures, but several recent studies.
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. Effects that scientists had predicted in the past would result from global climate change are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves.

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. As humans, every aspect of our life is reliant on the natural environment. This includes the food we eat, the air we breathe, the water we drink, the clothes we wear and the products that are made and sold to create jobs and drive the economy.
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.
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.

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 Much has been learned, and this knowledge base is continuously being updated and expanded with new research results.
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. Global warming is already being associated with increases in the incidence of severe and extreme weather, heavy flooding , and wildfires —phenomena that threaten homes, dams, transportation networks, and other facets of human infrastructure. Temperature increases related to global warming have been the most pronounced at the poles, where they often make the difference between frozen and melted ice. Polar bears rely on small gaps in the ice to hunt their prey.
Замечательно. Он опустил шторку иллюминатора и попытался вздремнуть. Но мысли о Сьюзан не выходили из головы. ГЛАВА 3 Вольво Сьюзан замер в тени высоченного четырехметрового забора с протянутой поверху колючей проволокой.
Выходит, мне придется встать. Он жестом предложил старику перешагнуть через него, но тот пришел в негодование и еле сдержался. Подавшись назад, он указал на целую очередь людей, выстроившихся в проходе. Беккер посмотрел в другую сторону и увидел, что женщина, сидевшая рядом, уже ушла и весь ряд вплоть до центрального прохода пуст.
Лиланд Фонтейн окинул своего помощника убийственным взглядом. - Я был .
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.Vebotttravuk1967 28.04.2021 at 22:18
