Rates of climate change in deep oceans could be severely affected, even in the best case scenario: study

The video discusses climate velocity, which is the rate at which marine mammals must move to find suitable water temperatures as ocean layers warm. It explores three scenarios of greenhouse gas emissions: immediate reduction, mid-century reduction, and continued rise. Even with immediate reductions, climate velocity in the mesopologic layer could increase significantly by mid-century, affecting marine life.

What is climate velocity?

• The velocity of ocean currents

• The speed at which marine mammals swim

• The rate at which ocean temperatures change

• The speed at which marine mammals must move to stay in suitable temperatures

Which scenario describes emissions starting to fall immediately?

• Emissions continue to rise until 2100

• Emissions start falling now

• Emissions fall in the middle of the century

• Emissions remain constant

In which scenario do emissions continue to rise until 2100?

• Emissions decrease gradually

• Emissions start falling now

• Emissions fall in the middle of the century

• Emissions continue to rise until 2100

What is the Mesopologic layer?

• The layer from 200 meters to 1 kilometer deep

• The ocean surface layer

• The deepest ocean layer

• The layer where sunlight penetrates

How might climate velocity change in the Mesopologic layer by mid-century?

• Increase to 100 kilometers per decade

• From 6 kilometers per decade to 50 kilometers

• Remain constant at 6 kilometers per decade

• From 50 kilometers per decade to 6 kilometers
