Answer:
Climate change, also called global warming, refers to the rise in average surface temperature on Earth. An overwhelming scientific consensus maintains the 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.
Global warming is measured by the increase in the average global temperature of the Earth. Along with our currently increasing average global temperature, some parts of the Earth may actually get colder while other parts get warmer—hence the idea of average global temperature. Greenhouse gas-caused atmospheric heating and also increases the unpredictability of the weather and climate, and dramatically increase the severity, scale, and frequency of storms, droughts, wildfires, and extreme temperatures.
Effect of Global Warming :
#Mass migration and security threats:
Global warming is likely to increase the number of "climate refugees"—people who are forced to leave their homes because of flooding drought, storm, or other climate related disasters.
#On Ocean:
Because of global warming, permafrost and ice are melting massively at the poles, increasing the sea level at a rate never known before. In a century, the increase reaches 18 cm (including 6 cm in the last 20 years). The worst case scenario is a rise of up to 1m by 2100.
#Wet and Dry:
Water will be the primary vector through which climate change will make its presence known. Because a warmer atmosphere can hold more water, precipitation patterns will change dramatically, with the trend being towards more water coming down at once, leading to increased runoff and flooding, with less water being absorbed into the ground. Other areas will be deprived of rain altogether, becoming deserts as a result.
#Health:
Global warming impacts threaten our health by affecting the food we eat, the water we drink, the air we breathe, and the weather we experience.
The severity of these health risks will depend on the ability of public health and safety systems to address or prepare for these changing threats, as well as factors such as an individual's behavior, age, gender, and economic status. Impacts will vary based on a where a person lives, how sensitive they are to health threats, how much they are exposed to climate change impacts, and how well they and their community are able to adapt to change.
