It is a form of static electricity.
Free electrons most definitely repel each other. Any attempt to create a buildup of electrons in a specific spot will eventually result in the repulsion amongst these electrons to overcome the attempt to collect them. When you rub your skin against a wool rug on a dry day, you build up a surplus of free electrons on your skin. The repulsion between these free electrons cause this surplus to scatter to all parts of the skin, thus permitting a discharge of them to occur at any place in your skin.
They don't help with global warming naturally but the large buildup of greenhouse gases does assist with global warming.
Its all called electron shielding.

Sparks! And when the distance is large enough, lightning!

It is a form of static electricity.
a buildup of electrons on an object is called a blank charge
Electrons don't jump from the nucleus, because there are no electrons in the nucleus. They DO jump, or can jump from one orbit to another. If it jumps to a higher orbit, then energy must be added, and if it jumps, or falls to a lower orbit, energy is released.
if there is a large amount of electrons, heat will be conducted very fast.
Electrons! (Although it is possible that some other charged particle is causing your static charge, electrons are the most likely culprit.)
