The concentration of greenhouse gases in the atmosphere is believed to have increased because of the burning of fossil fuels, the eruption of volcanoes, and deforestation, among other things. What is an increase in atmospheric greenhouse gases most likely to cause?
A.
a global decrease in the sea level
B.
extreme weather events
C.
less severe acid rain
D.
an increase in water pollution

  the awnser would be   D

An increase in atmospheric greenhouse gases are likely to cause many different things. Here are a few examples:

- Greenhouse gases (such as carbon dioxide, methane..) will cause the earth to get hotter. A hotter earth basically means global warming.

- The increased temperature will cause the polar ice caps to melt, which in turn increases sea levels (making some low-lying areas prone to flooding) and destroys habitats for many species (polar bears, for example).

- Extreme weather will become more commonplace, droughts will occur more often.
