The brachialis does not act at the shoulder and the coracobrachialis does not act at the elbow joint. explain

Coracobrachialis  is the first muscle that gets innervation. it is involved in the flexing of shoulder and its adducts at the glenohumeral point. It does not cross elbow joint that's why it has no function there.

Brachialis is the essential versatile flexor of elbow joint. It originates at the upper arm almost mid of humerus, from the distal portion and inserts on ulna. that is why it can not have any kind of influence on shoulder.

it would affect precipitation by causing flooding in some areas of the world due to climate increasing, causing the glaciers in the northern and southern pole of our planet to melt.

i wish you would have provided choices to simplify it and allow me to give an exact answer.
