How do scientists typically measure the impact of the greenhouse effect?

Scientists typically measure the impact of the greenhouse effect using satellite imagery because it allows for comprehensive monitoring of Earth's surface and atmosphere. Satellites equipped with various sensors can collect data on temperature changes, greenhouse gas concentrations, and radiation levels from space. This information is crucial for understanding how greenhouse gases are impacting climate patterns, energy balance, and heat distribution around the planet.

Satellite imagery provides a broad, consistent, and systematic view of changes over time, making it possible to track global trends and regional variations. This method also enables scientists to observe phenomena such as the melting of ice caps, changes in vegetation coverage, and shifts in weather patterns, directly linking these observations back to the greenhouse effect.

While ocean currents, thermal imaging, and weather balloons play roles in atmospheric studies, they are focused on more localized data rather than providing the extensive global perspective necessary to measure the comprehensive impact of the greenhouse effect.
