Uncertainties - How Do We Know?

The video explains how rising CO2 levels from fossil fuel burning are linked to global warming. It discusses three key aspects: physics, forcings, and fingerprints. The physics shows CO2's warming influence, while investigations into other forcings like solar activity and ocean heat reveal no alternative causes. CO2 fingerprints, such as warming patterns and model predictions, align with observed data. Human activities, particularly increased greenhouse gases, are necessary to explain recent warming trends, as models with only natural factors show cooling.

What are the three pieces of the puzzle that help us understand the warming caused by rising CO2?

How does the warming influence of CO2 differ from that of the sun?

What is meant by 'fingerprints' in the context of climate change?

What predictions do computer models make regarding temperature changes in different regions?

Why is it important to include human factors in climate models?
