Understanding Ocean Heat Storage and Climate Change

What was the climate puzzle that scientists faced between 2003 and 2012?

• An unexpected rise in sea levels

• A stabilization of global surface temperatures

• A sudden increase in global temperatures

• A decrease in CO2 levels

Where did scientists find the missing heat that was not reflected in global surface temperatures?

• In the Arctic ice

• In the atmosphere

• In the Earth's core

• In the subsurface layers of the Pacific and Indian oceans

What tool did scientists use to measure ocean temperatures and gather data on heat storage?

• Weather satellites

• Underwater drones

• Deep-sea submarines

• The Argo array of sea probes

What is the Pacific Decadal Oscillation (PDO) and its significance in climate studies?

• A cycle of volcanic eruptions

• A short-term weather pattern affecting Europe

• A phenomenon related to solar activity

• A long-term climatic cycle affecting ocean heat distribution

What could be the potential impact if the PDO shifts to a positive phase?

• Accelerated global surface warming

• An increase in ice formation

• Stabilization of sea levels

• A decrease in global temperatures
