Why does the effect of rising global temperatures in the ocean have such a broad effect on Earth? a. As water cools, it can hold less carbon dioxide, so more CO is released into the atmosphere, where it is a greenhouse gas. b. As water warms, it can hold less carbon dioxide, so more CO is released into the atmosphere, where it is a greenhouse gas. c. As water warms, it can hold more carbon dioxide, so less CO is released into the atmosphere, where it is a greenhouse gas. d. There is no overwhelming effect due to rising global temperatures.
