Question

Explain factors affecting global warming

Answer 1

Answer:

Explanation:

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.Many impacts of climate change have already been observed, including glacier retreat, changes in the timing of seasonal events (e.g., earlier flowering of plants), and changes in agricultural productivity. 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.

Future effects of climate change will vary depending on climate change policies and social development.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.Geoengineering is another policy option.

Near-term climate change policies could significantly affect long-term climate change impacts.Stringent mitigation policies might be able to limit global warming (in 2100) to around 2 °C or below, relative to pre-industrial levels. Without mitigation, increased energy demand and extensive use of fossil fuels might lead to global warming of around 4 °C. Higher magnitudes of global warming would be more difficult to adapt to,and would increase the risk of negative impacts.

The effects can pose an existential threat to human civilization by 2050.

This article doesn't cover ocean acidification, which is directly caused by atmospheric carbon dioxide, not the warming of global warming itself.
