The video discusses the ocean's decreasing effectiveness in absorbing atmospheric carbon due to warming temperatures and slowed circulation. Warmer oceans hold less carbon, similar to how warm soda releases gas. Slower ocean circulation reduces carbon transfer to the deep ocean. The carbon cycle has different response times; CO2 emissions warm the planet immediately, but long-term absorption by Earth's systems takes centuries.

Why does warm water hold less carbon compared to cold water?

• Warm water has more dissolved oxygen.

• Warm water molecules are more active, reducing carbon solubility.

• Warm water is denser than cold water.

• Warm water has a higher pH level.

What is one consequence of a warmer climate on ocean circulation?

• It increases the speed of ocean currents.

• It enhances the ocean's ability to absorb carbon.

• It slows down the ocean's circulation.

• It decreases the ocean's temperature.

How does slowed ocean circulation affect carbon absorption?

• It speeds up the carbon absorption process.

• It enhances the ocean's capacity to store carbon.

• It reduces the ocean's ability to pull carbon into the deep ocean.

• It increases the ocean's surface area.

What happens to CO2 emissions in the short term?

• They immediately cool the planet.

• They have no immediate effect on the climate.

• They immediately begin to warm the planet.

• They are instantly absorbed by the ocean.

How long can it take for the ocean to move absorbed CO2 into the deep ocean?

• 1 to 10 years

• 1000 to 2000 years

• 100 to 1000 years

• 10 to 100 years
