Question

Give some consequences of global warming

Answer 1

Answer:

The effects of global warming are the environmental and social changes caused (directly or indirectly) by human emissions of greenhouse gases. There is a broad 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 extreme weather events, glacier retreat,[2] changes in the timing of seasonal events[2] (e.g., earlier flowering of plants),[3] changes in agricultural productivity,[2] sea level rise, and declines in Arctic sea ice extent.[4]

The physical effects of future climate change depends on the extent of prevention efforts (i.e., reducing greenhouse gas emissions). The social impact of climate changes will be further affected by our efforts to prepare for changes that do occur.[5][6] Climate engineering is another policy option, although there are uncertainties regarding its effectiveness and little is known about potential side effects.[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 the warming of global warming itself.

Answer 2

Answer:

______________________________________

Some consequences of global warming are as follows :-

______________________________________

•The coral reefs are being affected in nearly all the world oceans.The increasing sea temperature has wiped out 90% of the coral in Indian ocean.

•Coral reefs, complex ecosystem that are sometimes referred to as the rainforests of the sea, not only serve as breeding grounds for many species of marine life, they also protect coast lines from storms.

•Increasing global temperatures may affect the regional climate or atmospheric changes with regard to the temperature Precipitation, soil moisture etc. All those consequences of increase in global temperature may pose serious probelems in the ecological balance.
