Question
Which of the following are potential impacts of oceans on human populations as the result of climate change in the current century?
Select FOUR correct answers, each worth one point! (4 points)
Responses

Ocean acidity increases with ocean warmth and may threaten the survival of some species, such as those that find it more difficult to produce shells in ocean waters with too high a level of acidity, resulting in changes to ecosystems and impacting human food sources.

Warmer ocean waters will cause the migration of some marine species and the disappearance of others, affecting people who fish for a living and/or depend off of food from the ocean.

Due to rising temperatures, many species will thrive and reproduce, resulting in additional food sources for animals and humans.

Rising temperatures and melting polar ice may result with coastal communities dealing with increased flooding due to sea level rise.

Answer 1

The four correct answers regarding the potential impacts of oceans on human populations as a result of climate change in the current century are:

1. Ocean acidity increases with ocean warmth and may threaten the survival of some species, such as those that find it more difficult to produce shells in ocean waters with too high a level of acidity, resulting in changes to ecosystems and impacting human food sources.

2. Warmer ocean waters will cause the migration of some marine species and the disappearance of others, affecting people who fish for a living and/or depend off of food from the ocean.

3. Open currents could be affected and may change weather and climate patterns, which could have a major implications for humans.

4. Rising temperatures and melting polar ice may result with coastal communities dealing with increased flooding due to sea level rise.

The statement about species thriving and reproducing due to rising temperatures is generally more optimistic and less likely to be universally applicable, given the overall negative effects of climate change on marine ecosystems.
