Referring to the graph shown below, which of the following statements best describes the trend in global sea ice coverage in the past 1400 years plus? a. Total ice coverage has fluctuated but increased over the last 1400 years, with it's greatest extent in the last 50 years. b. Total ice coverage has remained relatively constant at 10 million square km for the last 1400 years until about 1960 when it dramatically decreased. c. Total ice coverage has steadily decreased over the last 1400 years. Which of the following would be the most likely causes of the trend described in the previous question? a. Carbon dioxide emissions were high for 1000's of years during the Agricultural Revolution, and rapidly dropped in the last 150 years, causing the changes seen in sea ice coverage. b. Emissions of carbon dioxide remained relatively low over the past few 1000 years, then increased steadily after the Industrial Revolution and correlate well with the trends in sea ice cover over the last 1400 years. c. Emissions of carbon dioxide and methane by humans had no effect on global temperatures and melting of sea ice over the last 1400 years. Sea Ice Area in August: Last 1400+ Years 12 10 m ptember
