(04.05 HC)The graph shows how much sea levels changed from about 1870 to 2018. Items with pluses (+) are factors that caused ice to melt and sea levels to increase globally, while minuses (−) are variables that caused sea levels to decrease. These items are displayed at the time they were affecting sea level.© 2021 NASA’s Goddard Space Flight CenterWhich factor led to an increase in sea levels between 1960 and 1980?

(04.07 HC)Read the following case study:When carbon-dioxide-rich air meets seawater containing less carbon dioxide, the greenhouse gas diffuses from the atmosphere into the ocean as irresistibly as a ball rolls downhill. Today, about a quarter of human-produced carbon dioxide emissions get absorbed into the ocean. Once the carbon is in the water, it can stay there for hundreds of years.Warm, carbon-rich surface water flows in ocean currents to colder parts of the globe, releasing its heat along the way. In the polar regions, the now-cool water sinks several miles deep, carrying its carbon burden to the depths. That’s good for the atmosphere, but the ocean pays a heavy price for absorbing so much carbon: acidification. Carbon dioxide reacts chemically with seawater to make the water more acidic.(Source: climate.nasa.gov)Which statement best explains how the global changes in the case study could impact humans?
