give the effect of goobal warming
Answers
The effects of global warming are the environmental and social changes caused (directly or indirectly) by human emissions of greenhouse gases. There is a scientific consensus that climate change is occurring, and that human activities are the primary driver.[1] Many impacts of climate change have already been observed, including glacier retreat,[2] changes in the timing of seasonal events[2] (e.g., earlier flowering of plants),[3] and changes in agricultural productivity.[2] Anthropogenic forcing has likely contributed to some of the observed changes, including sea level rise, changes in climate extremes, declines in Arctic sea ice extent and glacier retreat.[4]
Future effects of climate change will vary depending on climate change policies[5] and social development.[6] The two main policies to address climate change are reducing human greenhouse gas emissions (climate change mitigation) and adapting to the impacts of climate change.[7] Geoengineering is another policy option.[7]
Near-term climate change policies could significantly affect long-term climate change impacts.[5][8] Stringent mitigation policies might be able to limit global warming (in 2100) to around 2 °C or below, relative to pre-industrial levels.[9] Without mitigation, increased energy demand and extensive use of fossil fuels[10] might lead to global warming of around 4 °C.[11][12] Higher magnitudes of global warming would be more difficult to adapt to,[13] and would increase the risk of negative impacts.[14]
This article doesn't cover ocean acidification, which is directly caused by atmospheric carbon dioxide, not global warming.
Global warming has affected the living of people globally. It has become the reason of many environmental and social level changes directly and indirectly all through the world. The emission of greenhouse gases increases the heat on the earth which has created living problem. According to the scientific consensus, it has been noted that the climate changes are continuous because of the global warming. Bad human activities are the primary driver of the increasing effects of the global warming. Many impacts of climate changes which are clearly observed are glacier retreat, fluctuations in the timing of the seasonal events, earlier flowering of plants, changes in agricultural productivity, increasing heat, etc.
