What is joint role in the climate system?Show answer
The coupling makes the climate system more sensitive than either cycle alone would suggest. Extra carbon dioxide warms the surface; the warmer surface evaporates more water, and the added water vapour strengthens the greenhouse effect further, the water-vapour feedback. At the same time, warmer oceans dissolve less carbon dioxide, so the ocean sink weakens and atmospheric carbon dioxide rises faster. These cross-cycle feedbacks are why understanding climate change requires treating water and carbon together rather than in isolation.
