Answer 2

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]
