Answer:
"climate change" means a change in climate that persists over a sustained period of time.[15][16] The World Meteorological Organization defines this time period as 30 years.[15] Examples of climate change include increases in global surface temperature (global warming), changes in rainfall patterns, and changes in the frequency of extreme weather events. Changes in climate may be due to natural causes, e.g., changes in the sun's output, or due to human activities, e.g., changing the composition of the atmosphere.[17] Any human-induced changes in climate will occur against a background of natural climatic variations[17] and of variations in human activity such as population growth on shores or in arid areas which increase or decrease climate vulnerability.[18]
Also, the term "anthropogenic forcing" refers to the influence exerted on a habitat or chemical environment by humans, as opposed to a natural process.[19]
"Detection" is the process of demonstrating that climate has changed in some defined statistical sense, without providing a reason for that change. Detection does not imply attribution of the detected change to a particular cause. "Attribution" of causes of climate change is the process of establishing the most likely causes for the detected change with some defined level of confidence.[20] Detection and attribution may also be applied to observed changes in physical, ecological and social systems.
Explanation:
Explanation:
the addition of certain gases like carbondioxide , methane , nitrous oxide ,ozone and CFC ( Cloro floro carbon ) increase the temperature of earth ,formaing an insulating layer .The surface becomes hot due to solar radiation .these radition are normally reflected back into the space . However ,due to persence of inculating layer the heat remain with in the earth's atmosphere and increase its temperature . This is called globel Warming.
WHY GLOBEL WARMING HARMFUL---
Globel warming is the melting of polar ice caps which contributes to the rise in the level of water in ocean .It is also called greenhouse effect.
