Key Idea.
Section 1
Quantifying Light Energy
Scientists collect quantitative data to measure exactly how much energy arrives at different locations on Earth.
By comparing "Solar Intensity" data, we can confirm that Australia receives a significantly higher amount of energy per square meter than many other places. This intense energy input is a primary suspect in the health investigation.
Section 2
Cumulative Energy and Correlation
Damage to materials is often a result of cumulative energy—the total amount of energy absorbed over a long period.
Even if sunlight is not immediately burning, small amounts of energy absorbed every day add up over years to cause significant damage.
