Carbon dioxide, methane, and nitrous oxides levels in the atmosphere are higher now than in the past 800,000 years.

Which of the following statements about global climate change is correct? Global sea levels are falling. Carbon dioxide, methane, and nitrous oxides levels in the atmosphere are higher now than in the past 800,000 years. Natural processes quickly remove surplus greenhouse gases from the atmosphere, so reduction of emissions now will restore the original climate equilibrium. Extreme weather events are less frequent and less severe now than in the past century. Glaciers and ice caps have decreased in size in the Northern Hemisphere but not in the Southern Hemisphere.
