With visualizations we can see the entire planet from all angles at once. We can see the invisible – such as water vapor in the atmosphere and the way air flows around the world.
Factors that have the power to change global climate can be natural, like volcanic eruptions and changes in solar energy, or caused by humans, like the addition of greenhouse gases to the atmosphere.
