Ned wants to demonstrate that global warming is indeed a real occurrence within our world. Ned’s speech will be addressing a: a. question of policy b. question of fact c. question of theory

b. question of fact

Explanation:

A policy represents a proposed principle of action by an organization, individual or government.

A fact represents a process or an event that has been proven to be always true.

A theory is a hypothesis that has been proven by several independent individual or researcher.

Global warming means the average increase in global temperature as a result of absorption of more radiation by greenhouse gases. The phenomenon has been established and proven as a fact.

Hence, Ned will be addressing a question of fact rather than a question of policy or theory.

The correct option is b.

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
