Which of the following is predicted to be an impact of global warming?
a. extreme weather
b. ocean acidification
c. species extinction
d. all of the above

The correct answer is the following: option D. Extreme weather, ocean acidification and species extinction are all predicted impacts of global warming. The term "global warming" is used to define the long-term rise in the average temperature of the Earth's climate system. Global warming is already and will keep on carrying a set of impacts in the world, as we know it. Extreme weather such as records of high temperature and low temperature as well, stronger and more dangerous storms, hurricanes and tornadoes are impacts of global warming. Ocean acidification, which is the ongoing decrease of the PH of the ocean, will join the climate changes to make the world an inhospitable habitat for a lot of species, that will become extinct.
