which of the following is the consequences of global warming
Answers
Answer:
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. Many physical impacts of global warming are already visible, including extreme weather events, glacier retreat,[8] changes in the timing of seasonal events (e.g., earlier flowering of plants),[9] sea level rise, and declines in Arctic sea ice extent.[10] The future impact of global warming depends on the extent to which nations implement prevention efforts and reduce greenhouse gas emissions. Ocean acidification is not a consequence of global warming, but instead has the same cause: increasing atmospheric carbon dioxide.
Climate change has already impacted ecosystems and humans as well.[11] In combination with climate variability, it makes food insecurity worse in many places[12] and puts pressure on fresh water supply. This in combination with extreme weather events, leads to negative effects on human health. Rising temperatures threaten development because of negative effects on economic growth in developing countries.[12] The social impact of climate change will be further affected by society's efforts to prepare and adapt.[13][14] Global warming already contributes to migration in different parts of the world.[15]
Near-term climate change policies significantly affect long-term climate change impacts.[13][16] Stringent mitigation policies might be able to limit global warming (in 2100) to around 2 °C or below, relative to pre-industrial levels.[17][18] Without mitigation, increased energy demand and extensive use of fossil fuels[19] might lead to global warming of around 4 °C.[20][21] With higher magnitudes of global warming, is more likely that societies and ecosystems will encounter limits to how much they can adapt.[22] Stronger warming increases the risk of negative impacts.[23]A broad range of evidence shows that the climate system has warmed.[47] Evidence of global warming is shown in the graphs (below right) from the US National Oceanic and Atmospheric Administration (NOAA). Some of the graphs show a positive trend, e.g., increasing temperature over land and the ocean, and sea level rise. Other graphs show a negative trend, such as decreased snow cover in the Northern Hemisphere, and declining Arctic sea ice, both of which are indicative of global warming. Evidence of warming is also apparent in living (biological) systems such as changes in distribution of flora and fauna towards the poles.[48]
Human-induced warming could lead to large-scale, abrupt and/or irreversible changes in physical systems.[49][50] An example of this is the melting of ice sheets, which contributes to sea level rise and will continue for thousands of years.[51] The probability of warming having unforeseen consequences increases with the rate, magnitude, and duration of climate change.[52]
