Which of the following might be an observation related to global temperature increases? glaciers in many areas of the world are shrinking. the number of predatory birds in an area is decreasing over time. there is an increase in skin cancer deaths in the united states. cfc concentrations in the atmosphere are high.

High CFC concentrations in the atmosphere are an observation related to global temperature increases.

CFC concentrations in the atmosphere are high

Explanation:

Detailed statistical analysis shows that Chlorofluorocarbons (CFC) are the most vital engine for global climate change. The data even suggests that cosmic ray tracing in CFC's has caused polar ozone holes and global warming.

By demonstrating the relationship between CFC, ozone depletion and temperature changes in Antarctica, Professor Lu established an almost perfect correlation between the rise in global atmospheric temperatures and CFC's.

The variation in global temperature showed almost sharp linear correlation with CFC up to 0.97.

this is math not biology xd
