Question

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.

Answer 1

Glaciers shrinking in various regions is a strong indicator of global temperature increases. This is part of the broader effects of global warming, which include ecosystem disruption and rising sea levels linked to human-induced greenhouse gas emissions.

Step-by-step explanation:

An observation that might be related to global temperature increases is that glaciers in many areas of the world are shrinking. This phenomenon, often referred to as glacier recession, has been well-documented in various parts of the world, including Glacier National Park in Montana. The retreat of glaciers is a direct consequence of rising mean annual temperatures, which has been recorded at an increase of 1.33°C since 1900 in the park. As glaciers shrink, they contribute to rising sea levels and affect local ecosystems by reducing seasonal water supplies.

The impact of global warming is not limited to glacier retreat; it also encompasses the loss of polar ice fields, increases in extreme weather events, shifts in habitats and biodiversity, and a range of other ecological disturbances. These changes are indicative of the broader shifts occurring due to increases in greenhouse gas emissions, which have been linked to human activities such as the burning of fossil fuels.

Answer 2

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

Answer: 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.
